Long-term efficacy of percutaneous transluminal coronary angioplasty.
Percutaneous transluminal coronary angioplasty (PTCA) is a well-accepted procedure used in therapy for coronary artery stenosis. It is a delicate procedure depending upon the operator's experience and technique. Major efforts have been directed toward improving such performance. This is a report of our growing experience accumulated over the last eight years. From July 1983 to December 1990, 893 cases of coronary artery disease with a total of 1111 procedures received PTCA in this hospital. The success rate in dilatation increased year by year; to peak in 1990 (94%). PTCA was performed in 447 cases of single vessel disease; 310 cases of double vessels disease; and 136 cases of triple vessels disease. Dilated coronary artery lesions included left anterior descending artery, 637 (64%), right coronary artery, 198 (20%), and left circumflex artery 157 (16%). More than one procedure was undertaken in 178 patients, and about 20% patients had repeated PTCA. Major complications such as acute myocardial infarction developed in 3.0%. One point one percent had emergency surgery and the mortality rate was 1.8%. The majority of cases were followed up and appeared well after successful angioplasty. In conclusion, PTCA is an valuable procedure for treatment of critical coronary artery stenosis, with acceptable complications.
