Abstract

Background:
@EN Improvements in catheter equipments and increasing experience of the operators have brought about a broadening of the indications and applications of percutaneous transluminal coronary angioplasty (PTCA). In particular, coronary angioplasty
has
been
employed in total occlusions. We evaluated the initial success rate and safely of PTCA for total occlusive coronary artery disease.
@ES Methods:
@EN To assess the success rate and safety of PTCA for total coronary artery occlusion. the data of 24 patients 9male 19. female 5. mean age 55±9 years). in whom PTCA for total occlusion were performed, were examined.
@ES Results:
@EN Primary success rate of procedure was 66.7% 916 out of 24 lesions). The success rate according to the duration of total occlusion was 8 out of 11 (72.7%) with occlusion <4 weeks duration and 3 out of 7 (42.9%) with occlusion>4 weeks duration
(p=0.07). there was no differece in success rate according to vessel dilated (left anterior descending 75.0%. right coronary 44.4%) and lenght of occluded lesion (0.93±0.47 cm vs 1.05±0.55cm. p=0.35). Eight procedural failures included
inability
to
cross the lesion with a guide wire in 6 and inability to dilate the lesion in 2. but there was no emergency coronary bypass surgery or cardiac death.
@ES Conclusion:
@EN Even though the recanalization of occluded coronary arteries has a lower initial success rate than angioplasty for stenotic arteries. PTCA in total occlusion can be performed as a safe and effective therapeutic modality in selective patients.
