Resident training and minimally invasive cardiac surgery

To the Editor:
We enjoyed reading the editorial by Reardon and associates, titled "Minimally Invasive Coronary Artery SurgeryA Word of Caution" (J Thorac Cardiovasc Surg 1997;114:419-20), and we share many of the views and concerns expressed regarding minimally invasive coronary artery bypass grafting (MICABG). However, we were surprised to read that MICABG cannot be considered a truly successful procedure because it cannot be mastered by surgical residents. We would like to share with the readership of the Journal the experience of the Minimally Invasive Cardiac Surgery Program of the University of Pittsburgh. Within our Cardiothoracic Surgery Training Program (Bartley P. Griffith, MD, Program Director), our residents (PGY-6 and beyond) are being actively trained in MICABG as part of their coronary surgery armamentarium. For instance, during the 6-month period July to December 1997, our current chief resident (Dr. Lawrence Spier) performed as "first" surgeon 25 "full credit" MICABG operations (attending surgeon scrubbed and teaching while first assisting). The angiographic patency of the left internal thoracic artery to left anterior descending coronary artery in these 25 patients is 100%, whereas our overall angiographic patency is 97.8%. Our cardiothoracic surgery residents routinely participate in the preoperative patient selection for MICABG and follow-up after the operation. Furthermore, given our large volume of cases and our ability to attract new technologies, our residents are exposed and trained with a large variety of new devices for harvesting the left internal thoracic artery and mechanical stabilization of target vessels.
We believe that MICABG is a highly reproducible surgical technique in the current "mechanical stabilization" era and can be taught successfully to our cardiothoracic surgery residents with comparable results.
