Backgroung:
@EN Indications and applications of percutaneous transluminal coronary angioplasty (PTCA) have been broaden in recent years. We evaluated the initial success rate and safety of PTCA in multiple lesions and vessles.
@ES Methods:
@EN To assess the success rate and safety of PTCA in multiple lesions and vessels. the dats of 670 lesions from 28 patients (male 23. female 5, mean age 56±12 years). in whom PTCA for multiple lesions and vessels were performed. were examined.
Initial
results and complications were compared in 37 lesions undergoing multivessel and 23 lesions undergoing multilesion PTCA.
@ES Results:
@EAN Overall primary success rate of procedure wa s82% (49 out of 60 lesions). Angioplasty was attempted in mean 2.1 stenotic lesions per patient. Primary success rate per lesion was 84% (31 of 37) among those who unerwent multivessel and 78% 918
of 23)
among those who underwent multilesion PTCA (n>0.05). Success rate according to the combination of dilated vessels was 85.7% (12 of 14) in left anterior descending (LAD) and left circumflex (LCX), 83.3% (10 of 12) in LAD and right coronary artery
(RCA),
100.0%(4 of 4) in LAD and diagonal branch, RCA and LCX in 75.0% (3 of 4), and 66.7% (2 of 3 ) in LAD, LCX and diagnonal branch. Eleven failures (18.3%)included inability to pass the guide wire cross the lesion or inability to locate the balloon
catheter
in 5 (8.3%). inability to dilate lesions in 6 (10.0%). Complications included coronary dissection in 5 (8.3%), abrupt closure in 2 (3.3%), coronary spasm in 1 (1.7%) and majro branch occlusion in 3 (5.0%). but there was no emergecy coronary
bypass
surgery or cardiac death.
@ES Conclusion:
@EN Coronary angioplasty in selected patients with multivessel and multilesion coronary artery diseas might be useful and have relatively good inital results, but the long-term efficacies with other forms of treatment must be evaluated
prospectively.
