Multidisciplinary Heart Team Approach for Complex Coronary Artery Disease: Single Center Clinical Presentation

Abstract

Background The Heart Team approach is ascribed a Class I recommendation in contemporary guidelines for revascularization of complex coronary artery disease. However, limited data are available regarding the decision-making and outcomes of patients based on this strategy. Methods and Results One hundred sixty-six high-risk coronary artery disease patients underwent Heart Team evaluation at a single institution between January 2015 and November 2018. We prospectively collected data on demographics, symptoms, Society of Thoracic Surgeons Predicted Risk of Mortality/Synergy Between PCI with Taxus and Cardiac Surgery (STS-PROM/SYNTAX) scores, mode of revascularization, and outcomes. Mean age was 70.0 years; 122 (73.5%) patients were male. Prevalent comorbidities included diabetes mellitus (51.8%), peripheral artery disease (38.6%), atrial fibrillation (27.1%), end-stage renal disease on dialysis (13.3%), and chronic obstructive pulmonary disease (21.7%). Eighty-seven (52.4%) patients had New York Heart Association III-IV and 112 (67.5%) had Canadian Cardiovascular Society III-IV symptomatology. Sixty-seven (40.4%) patients had left main and 118 (71.1%) had 3-vessel coronary artery disease. The median STS-PROM was 3.6% (interquartile range 1.9, 8.0) and SYNTAX score was 26 (interquartile range 20, 34). The median number of physicians per Heart Team meeting was 6 (interquartile range 5, 8). Seventy-nine (47.6%) and 49 (29.5%) patients underwent percutaneous coronary intervention and coronary artery bypass grafting, respectively. With increasing STS-PROM (low, intermediate, high operative risk), coronary artery bypass graft was performed less often (47.9%, 18.5%, 15.2%) and optimal medical therapy was recommended more often (11.3%, 18.5%, 30.3%). There were no trends in recommendation for coronary artery bypass graft, percutaneous coronary intervention, or optimal medical therapy by SYNTAX score tertiles. In-hospital and 30-day mortality was 3.9% and 4.8%, respectively. Conclusions Integrating a multidisciplinary Heart Team into institutional practice is feasible and provides a formalized approach to evaluating complex coronary artery disease patients. The comprehensive assessment of surgical, anatomical, and other risk scores using a decision aid may guide appropriate, evidence-based management within this team-based construct.
