Surgical experience following percutaneous transluminal coronary angioplasty.
Percutaneous transluminal coronary angioplasty (PTCA) was attempted in 600 patients, 97 of which were considered unsuccessful. Review of our surgical experience in a large series of these procedures helps to confirm some facts regarding the unique interaction between these two modalities of myocardial revascularization. Serious complications are still relatively common, even when PTCA is performed in centers with broad experience. While emergency operation is not required in all major complications, about 7% of patients need immediate surgical intervention, which is usually performed on unstable patients, and thus associated with increased morbidity and mortality. The combined incidence of major complications, such as coronary dissection, occlusion, and spasms, still approaches 20% of attempts. In contrast to other studies, surgical mortality and morbidity do not appear to be higher in our series of operations on patients with complicated PTCA than in coronary bypass operations in general. This fact may attest to our practice of alerting all surgical services in anticipation of problems. Our short complication-to-operation completion time, averaging 123 minutes, may be partially responsible for the good results. We conclude that standby open-heart services for PTCA are warranted in most hospitals; however, it should not be performed in hospitals without surgeons who are experienced in the practice of open-heart surgery.
