Abstract
From June 2000 to April 2002, 100 cases (156 lesions) of percutaneous transluminal coronary angioplasty (PTCA) had been performed at Maharat Nakhon Ratchasima Hospital. Fifty seven percent of the patients were male. Mean age was 62.2 ± 9.3 years and mean ejection fraction was 63 ± 19.5%. The indication for PTCA consisted of chronic stable angina (67%), unstable angina (31%) and acute ST elevation myocardial infarction (MI) (2%). Emergency PTCA was performed on 4 cases with one patient in cardiogenic shock. The patients were classified into 3 groups, according to number of stenosed coronary arteries, single vessels 58%, double vessels 35% and triple vessels 70%. The vessels dilated were left anterior descending artery (LAD) 51.1%, right coronary artery (RCA) 16%, left circumflex artery (LCx) 30.8% and left main 1.92%. mean balloon size was 2.5 mm. The overall success rate of PTCA defined on residual diameter stenosis less than 50%, was 95%. In addition to PTCA, 140 stent implantation with mean stent size 2.95 mm. was performed. Complication of PTCA occurred in 6 cases (6%). It comprised 1 abrupt closure (1%), 1 acute stent thrombosis (1%), 1 subacute stent thrombosis, 2 groin hematoma and 1 acute fatal thrombosis of left anterior descending coronary with retrograde clot to the left main artery.
Conclusion: PTCA is the coronary interventional procedure that can be performed in Maharat Nakhon Ratchasima Hospital with high success rate and minimal complications.
