Randomized Trial to Compare Percutaneous Coronary Intervention Between Massachusetts Hospitals With Cardiac Surgery On-Site and Community Hospitals Without Cardiac Surgery On-Site - MASS COMM


Current American College of Cardiology Foundation (ACCF)/American Heart Association (AHA) guidelines list elective percutaneous coronary intervention (PCI) as a Class IIb indication for institutions without on-site cardiac surgery. Most of this is based on earlier observational data showing worse outcomes in patients undergoing PCI at such institutions. The current trial sought to study this question in a randomized, controlled fashion.
