OUTCOMES OF SUCCESSFUL VERSUS UNSUCCESSFUL PERCUTANEOUS CORONARY INTERVENTION IN CHRONIC TOTAL OCCLUSIONS: A TWO YEAR STUDY

Abstract

Objective: To determine the clinical outcomes of successful versus unsuccessful PCIs in CTOs.

Study Design: Single center, comparative cross-sectional study.

Place and Duration of Study: Army Cardiac Center, Lahore from January 2017 till December, 2018.

Material and Methods: A total of 218 patients of PCI for CTO with native CAD were recruited in our study. Patients with CTO lesion ≥3 months were included in our study. All the included patients had CTO lesion ≥3 months. All Patients information was recorded. Patients were followed for 2 year. Data was entered and analyzed in SPSS-21.

Results: We enrolled 218 patients, 200 (91.3%) were male patients while 18(8.2%) were females. Mean age of patients was 58.5 ± 9.4 years and range 37-87 years. 103 (47.0%) patients were hypertensive, 93 (42.7%) were smokers and 89 (40.8%) were diabetic. Out of 218 PCIs in CTOs successful were 14 7(67.4%) while unsuccessful were 71 (32.6%). The comparison between the two groups showed that gender, arteries involved, J-CTO score and initial approach to the lesion were found to be statistically significant (p<0.05). Most frequent reason of failure of procedure was inability of wire to cross the CTO lesion 65 (91.5). No deaths were reported during the procedures.

Conclusion: With increasing experience and better equipment recanalization of CTO coronary lesions is a safe and effective treatment option for patients with persistent Angina even on appropriate medical treatment.
