Practical Implementation of the Coronary Revascularization Heart Team

Multidisciplinary decision making has been shown to be highly effective in various aspects of medicine, most notably with the concept of tumor boards and transplant committees.1 ,2 The most updated guidelines for percutaneous coronary intervention (PCI), published jointly by the American College of Cardiology Foundation, American Heart Association, and the Society for Cardiovascular Angiography and Interventions, assign a class IC recommendation for the use of a collaborative Heart Team approach in the treatment of patients with complex coronary artery disease (CAD).3 The guidelines assert that this recommendation is based on retrospective analyses showing that patients with complex CAD referred for revascularization based on a Heart Team consensus have improved mortality compared with patients merely assigned to a particular strategy in the context of their trial enrollment. Despite the suggestion of improved mortality in this retrospective comparison, the Heart Team approach has not been adopted widely in the current clinical practice of cardiovascular medicine. This multidisciplinary innovation remains in its infancy, and numerous questions remain about its practicality, feasibility, and efficacy. For several reasons, there remains significant variability in the care delivered to patients with complex CAD.4 Numerous reports show that although differences in patient characteristics may explain some of the variability in revascularization decisions, much of this variance is physician driven, such as practicing in a fee-for-service model or high-risk anatomy for low-volume operators.4,5 As emphasis grows on informed decision making and patient-centered care, a critical evaluation of these difficult questions will be essential to discovering whether there is a clinically meaningful effect of the Heart Team approach on patients with complex CAD. Although the longstanding use of tumor boards in the field of oncology represents a functioning model of interdisciplinary care on which the Heart Team may be based, it is critical …
