ASSERTIONS
• Traditional barriers between medical specialties result in a provider-centric rather than a patient-centric healthcare system
• These barriers are not compatible with the effective application of today’s hybrid technologies
• Elimination of these barriers improves patient outcomes (win) and offers a non-zero opportunity for providers (win-win)– -> WIN-WIN-WIN

IMPACT OF DECENTRALIZED CARE
System Perspective• Poor information transfer• Duplicative care
– increases in direct costs• Decreased quality
Patient Perspective• Wastes patients’ time
– increase in indirect costs• Patients lost in system
– delays care• Patients lost to system
– go elsewhere• Patients forced to make decisions
based on complex information provided by multiple disparate sources with competing interests
![Page 12: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/12.jpg)
Compared w 4 other comparable countries, U.S. patients more likely to:-undergo duplicative testing-tell the same story to multiple HCPs-experience delay in reporting of results

IT IS POSSIBLE. . . • 87yo h/o B THR and L TKR, severe PHTN, walks w a cane but highly functional p/w
severe AS; eval for TAVR– Thurs: Referral secured by outreach team
• Facilitated direct MD-to-MD contact– Tues: Next Valve Clinic date seen by Cards, CTS, IC, Vasc
• TTE (Cards) – previously unscheduled• CTA C/A/P (Rads) – previously unscheduled
– Fri: Returned to referring MD for cardiac cath– Sun: Spent Mothers Day with family– Mon: Underwent TF-TAVR
• Uneventful case• Awake and extubated < 30 mins after the procedure
– Fri: Discharged on POD #5• Home before the NATO riots
Yes, but . . . this should NOT be a case study . . . it should be the standard of care

These barriers between specialties are no longer compatible with the effective application of
today’s hybrid therapies

Drugs Open Surgery
ONCE UPON A TIME…
Medical Physician Surgeon
• Its clear who provides services• More likely to be complementary, less likely competing
TREATMENT OPTIONS WERE DISCRETE
![Page 17: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/17.jpg)
Drugs Open Surgery
INTERVENTIONAL ERA: RECENT PAST
Interventions
• Technologies were competing and mutually exclusive, eg:• PCI (IC) vs CABG (CTS) aka “The Stent Wars”• Open distal bypass (VS) vs peripherial stenting (IC/IR)
![Page 18: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/18.jpg)
Drugs Open Surgery
HYBRID ERA: PRESENT
Interventions MISHybrid
• Differences are obscured• Its unclear who provides which services/treats which pts
![Page 19: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/19.jpg)
EXAMPLE: TAVRProcedural Steps• Planning CT and echo:
• Aortic Valve• Aorta• Lower extremities
• Vascular access– Percutaneous– Femoral, iliac, axillary– Apical, aortic
• Pass large bore- sheath -- approved device is only slightly smaller in caliber than a garden hose
• Cross the aortic valve• Position Valve under echo/fluoro• Balloon valvuloplasty/valve replacement• Closure of access site
• Perc• Open
• Complications• Valve embolization• Dissection• Coronaries• Vascular injury
Specialty most suited
• Cards/CT• Rads/CT/VS• Rads/VS/IC
• IC/VS• VS/CT• CT• VS/CT
• IC• CT/Cards/IC• IC
• IC/VS• VS/CT
• CT• CT• IC• VS
No single specialty competent to do all parts based on traditional training/skills. . .
A TEAM IS REQUIRED
![Page 20: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/20.jpg)
WHAT IS A TEAM?• Comprises a group of people linked in a common purpose
• Especially appropriate for conducting tasks that are high in complexity and have many interdependent subtasks
• Members have complementary skills
• Allow each member to • maximize their strengths • minimize their weaknesses • generates synergy
• Improves on what is possible for an individual actor
![Page 21: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/21.jpg)
In baseball, team members have different skills and fulfill
different roles
![Page 22: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/22.jpg)
THIS IS A PITCHING STAFF…NOT A BASEBALL TEAM
Curveball
Submarine
Split-finger fastball
Leftie
Knuckleballer• Slightly different nichesBUT…• Working in parallel, not together• All filling the same role
![Page 23: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/23.jpg)
IN HEALTHCARE, “TEAM” MEMBERS OFTEN HAVE NEARLY IDENTICAL SKILLS
![Page 24: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/24.jpg)
Elimination of these barriers improves patient outcomes and offers a non-zero opportunity for
providers
![Page 25: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/25.jpg)
GAME THEORY
Zero Sum Scenarios– participant's gain (or loss) of
utility is exactly balanced by the losses (or gains) of the utility of the other participant(s).
– If one gains, another losses
– Only Win-Lose possible
– Example: party goer eats a piece of cake…there is less cake for the other partiers
Non-Zero Sum Scenarios– a participant's gain (or loss)
of utility is not balanced by the losses (or gains) of the utility of the other participant(s).
– If one gains, another may also gain
– Win-Win possible
– Example: Prisoners’ dilemma
![Page 26: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/26.jpg)
PRISONERS DILEMMA
Prisoners DO cooperate . . . less jail time (WIN-WIN)
Prisoners DO NOT cooperate . . . more jail time (LOSE-LOSE)
Prisoners DO NOT cooperate . . . more jail time (WIN-LOSE)
Prisoners DO NOT cooperate . . . more jail time (WIN-LOSE)
In a NON-ZERO scenario. . . one player does not need lose for
another to win. . .WIN-WIN scenarios exist
![Page 27: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/27.jpg)
OUR WORLD IS INCREASINGLY NON-ZERO
“The more complex societies get . . . the more complex the networks of interdependence. . . the more people are forced in their own interests to find. . . win-win [non-zero] solutions instead of win-lose [zero] solutions. . .
We find as our interdependence increases . . . we do better when. . . people [around us] do better as well.”
—an ex-US President, December 2000
![Page 28: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/28.jpg)
OUR WORLD IS INCREASINGLY NON-ZERO
“The more complex therapies get . . . the more complex the networks of interdependence. . . the more clinicians are forced in their own interests to find. . . win-win [non-zero] solutions instead of win-lose [zero] solutions. . .
We find as our interdependence increases . . . we and--our patients--do better when. . . people [around us] do better as well.”

REVELATION
• In a 25 mile radius of UofC, there are: – 75 cardiac surgery programs (more than NYS - 7x the pop) – 79 cath labs (more than Canada – 12.5x the pop)– No dominant center
• Each center is doing a fraction of the total CV work in the area
• What if we worked together?– try to take cases from the guys across the street . . . – rather than cases from the guys across the hall?
![Page 30: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/30.jpg)
OUR EXPERIMENT• Create a team composed of members with different skills sets/from different
disciplines• Cardiology• Vascular surgery• Radiology
• Objectives: • To expand our practice • To increase our volume• To improve our outcomes• To deliver patient-centric care
• Methods:• Sought out opportunities to collaborate• Leverage unique skills and existing systems
• Interventional Cardiology• Cardiac Surgery• Anesthesiology

TRANSPARENCY/SHARE THE WORK
• Eliminate the “I’m a hammer . . . you’re a nail” approach = Pt gets the procedure the MD can offer
• Instead, offer the best solution for the pt– Coronary revascularization cases discussed (IC and CTS)– Valve cases discussed in valve conf and valve clinic
(Cards/CTS/IC)– Aortic cases discussed in aortic conf and aortic clinic
(CTS/VS/Cards)
![Page 33: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/33.jpg)
LEVERAGE ESTABLISHED SYSTEMS• Example: ECMO
– Emergency surgery only exists in Level 1 Trauma Centers….and on TV
• OR: 1-3 hours to active– 80%+ of ECMO is now initiated in the cath lab– Advantages
• Cath lab - Faster and Cheaper– activated in 30-60 mins– Cost < 20% of the OR
• Better imaging for perc access, if needed• Opportunity for collaboration

WORK-UP
Aortic root injection Selective cannulation of pseudoaneurysm using
coronary catheter
![Page 49: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/49.jpg)
THE PLAN• 10mm graft to LSCA for
device access (Vasc)• 8mm graft to RSCA to
initiate CPB (CTS)• Selective catheterization of
LCA (IC)
• Approach allowed for:• Control BP/volume
status for more precise deployment of device
• Protection if coronary covered

THE TEAM
IC CTS VS Cards Imaging/Anes
![Page 51: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/51.jpg)
THE RESULT
• Successful deployment• Exclusion of PSA• D/ced home POD #2
![Page 52: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/52.jpg)
CSB/TEVAR• 72yo w large penetrating ulcer requiring CSB and TEVAR• Possible approaches:
– Advantages of Concomitant Approach:• Single trip to the OR; Less OR utilization• Potential for decrease LOS, faster recovery
– Advantages of Staged Approach• No physician fatigue – 2 short cases• “If complication occurs, we know who caused,”
– but…if the patient has a stroke, do THEY really case “who caused it”?
• Actual Approach - Concomitant – HD #1: Spinal drain by Anes – HD #2: 5 hours in OR; labor divided -> little stress/fatigue, max learning
opportunity• VS + fellow -> LCA-graft anastomosis • CTS + fellow -> LSCA-graft anastomosis• VS + CTS + fellows -> TEVAR
– HD #4: pt discharged

CSB/TEVAR
• Secondary advantage of collaboration – prepared for complications– If arch is covered by VS – CTS likely is needed for bailout– If iliac is avulsed by CTS – VS likely is needed for bailout– If each service is not immediately available…complication
is likely irreversible before help arrives– If each service is committed to primary treatment choice,
they will be more committed bailout if needed

COMPLICATION AFTER TAVR• 77yo with severe, symptomatic AS
– Deemed in operable 2/2 h/o radiation to chest – Undergoes uneventful TAVR procedure– LFA sheath pulled in ICU– At MN, noted to have no pulses below L knee– Vascular surgeon involved in pts original TAVR case was consulted– Taken immediately to OR for embolectomy
• No discussion of possible vasospasm, trial heparin, watchful waiting– Pulses regained in OR– Pts remaining hosp course uneventful
![Page 55: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/55.jpg)
R/O AoD• 68yo w substernal pain x 5 hrs presents to an OSH
– Reported to have moderate to severe AI and moderate pericardial effusion– Presumed diagnosis: Type A AoD
• Outside ED called 855-808-2223– Transfer center paged covering surgeon, but in OR (unable to be reached)– CT Surgeon was reached….accepted the pt– UCAN (helicopter) dispatched
• Pt directly to OR– TEE revealed: mild AI, trace effusion, moderate TR– No evidence of AoD, but (+) RV dysfunction
• Pt transferred directly to cath for aortography, diagnostic cath possible PCI• RCA stent placed• Repeat CT and TEE on HD#1 – no evidence of AoD• Discharged on POD#3
Even more compelling when hybrid room is
available
![Page 56: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/56.jpg)
AoD• 61 yo M presented to OSH with substernal chest pain radiating to the back
– Diagnosis: Type A AoD
• Outside ED called 855-808-2223 -> paged Ao pager
• Reached Vasc Surgeon 1st….accepted the pt– Pact to “Just say YES”
• eg AoD accepted by cards, AAA by CTS, Type As by Vasc– Without collaboration, vasc surgeon will tell OSH to find a CT surgeon
• OSH may call other hospital

FAMILY LETTER“I’d like to thank you for saving my father’s life last week. My dad is not only alive, but is walking, talking, and ornery as ever all thanks to your expertise. It truly has been a surreal week to say the least. I feel very fortunate to know that my father was in such good hands.
“I wanted to extend my most sincere gratitude towards you and your extremely skilled and professional team at U of C for your amazing and miraculous work. Thank you a million times over, from the bottom of our hearts (and the top of my father’s newly grafted aorta).” Best regards

BLURRING LINES• Cross coverage
– Disease-specific pagers • TAVR covered by IC/CTS• Aortic covered by VS/CTS
– Clinics• Aortic staffed by VS/CTS/CV Radiology• Valve staffed by Cards/Cards Imaging/IC/CTS/VS
– Cases
• Pact to “Just say YES” (eg .AoD accepted by cards; AAA by CTS; Type As by Vasc)
• Cross training: – in combined cases, attempt the part less comfortable w under the
supervision of more experience operators
![Page 64: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/64.jpg)
COMMON OUTREACH• CME w outreach team
• Disease specific contact/pager– Aortic disease: 855-808-2223 (UCCAD)/8222– TAVR: 855-808-8287 (TAVR)– Worked with the call center to initiate a phone tree
• Websites– Visits/day: ~200– Pageviews/day: ~300– Clinic Visits/week: 1-3– 4 OR cases per mo– Retention of clinic patients– Bottom line < $3000

POTENTIAL BENEFITS
• Patients• Providers• Healthcare System
![Page 66: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/66.jpg)
POTENTIAL BENEFITS: PATIENTS
• Care focused on patients condition– Avoid competing sales pitches
• Higher quality– Receive appropriate therapies– More eyes on the pts (attendings/fellows/APNs/PAs from
multiple service)• Decreased costs
– Direct and indirect– Decreased delay in care
• Higher patient satisfaction
![Page 67: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/67.jpg)
POTENTIAL SUCCESS: PROVIDERS
• Better working environment– Common mission– No finger pointing– Egos checked at the door
• Easier acquisition of others’ input – Planning procedures, management, complications
• Providers more invested in al CV patients• Broader understanding of disease process and available therapies• Learning new skill sets• “CCF Effect” – MDs refer to team/organization, not a specific MD
– Decreases hurt egos when a CTS refers a complex CTS pt to an outside CTS; IC a complex IC pt; or VS a complex VS pt
![Page 68: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/68.jpg)
POTENTIAL SUCCESS: PROVIDERS
• Expanding practice – TAVR, Frozen Elephant Trunk, Asc Ao Stent Graft, Ao Arch Stent,
Antegrade Ao Stent, Perc Closure of PSA, Perc Closure of Aortic Valve, Pararenal Snokel, MD-Modified Stent Graft
• Increased volume
– TEVAR: 2010 - 3, 2011 – 8, 2012 – 20+ (through Aug; 40 projected)– EVAR: up 40% over previous year
• Academic productivity/TAVR Team– 2011: 50 publications– 2012: 40 (to date)
![Page 69: COLLABORATION IN CARDIOVASCULAR INTERVENTIONS: A NON-ZERO SOLUTION Mark J. Russo, MD, MS Assistant Professor of Surgery Co-Director, Center for Aortic.](https://reader037.fdocuments.net/reader037/viewer/2022103111/55199e7f55034643068b4ab8/html5/thumbnails/69.jpg)
POTENTIAL BENEFITS: THE HEALTH CARE SYSTEM
• Decreased resource utilization– Decreased duplicative testing– Decreased need for multiple encounters
• Higher quality care– More appropriate/balanced use of technology
• Team polices themselves for appropriateness rather than leaving it to an outside non-clinical entity (eg govt, insurance)
– Better outcomes

OBSTACLES• Playing field – need a hybrid room; available in Feb• “The Division of . . .Cardiac Surgery/Cardiology/Vascular Surgery . . .”
– Artificial divisions exist between groups that should naturally work together, particular in our 100% hospital-based employment model
• Resources – no mechanism to share across disciplines; different services
• Billing – who gets the RVUs; how to divide
• Personal Incentives• Reimbursement
– Prob not maximizing• Existing Culture
– buy-in not universal
