Abstract

Background- Although a total coronary occlusion is identified approximately in one third of the diagnostic cardiac catheterizations, still an attempted revascularization of total occlusion accounts for less than 8% of all percutaneous coronary interventions (PCI). Percutaneous Coronary Intervention (PCI) of chronic total occlusion (CTO) is one of the major challenges in interventional cardiology. It is now an well-accepted revascularization procedure.

 Methods: It was a prospective observational study conducted in National Institute of Cardiovascular Diseases, Dhaka, from July 2004 to June 2005. 50 consecutive patients with chronic total occlusion undergoing PCI were included in the study. Patients were observed during procedure and during the hospital stay.

Result: The mean age of the patients was 46.7 ± 9.3 and 48.0% were in the age range of 45-54 years. 24 patients had post MI angina, 20 patients had chronic stable angina and 6 patients had unstable angina. Technical success was in 98% cases and procedural success was in 94% cases. One patient developed vessel perforation and was treated by prolonged balloon inflation. There was no death or STEMI and only 2 patients developed NSTEMI.

Conclusion: In our study with the use of available facilities PCI in CTOs was possible with a high success rate. But dealing of more complicated lesion will require more improved technology and hardware. A study with larger number of patients and longer duration of follow up to determine the efficacy of the procedure in improving morbidity and mortality is needed.
