[Direct percutaneous transluminal coronary angioplasty]

Early reperfusion in acute myocardial infarction (AMI) effectively reduces mortality. Direct. percutaneous. transluminal coronary angioplasty (PTCA) is a recognized alternative to intravenous thrombolytic therapy in early AMI. Of 289 PTCAs performed during a year, 29 (10%) were direct PTCAs. Indications for direct PTCA in 21 patients (72%) were large infarcts, and in 8 (28%) cardiogenic shock. The left anterior descending artery was involved in 15 patients (52%), the right coronary artery in 10 (34%), the left circumflex in 3 (10%), and the left main artery in 1 (3%). Satisfactory opening of the occlusion was achieved in 26 (90%); there was partial success in 2 (7%) and failure in 1 (3%). 4 patients required stent deployment for treatment of dissection. There was no major complication. A patient in whom success was only partial, and the one in whom PTCA failed, were sent for operation. These data do not differ from our success rate in elective PTCA. It is concluded that direct PTCA is a safe procedure with a high rate of successful reperfusion in AMI.
