CHRONIC TOTAL OCCLUSION OF NATIVE CORONARY ARTERIES - PERCUTANEOUS CORONARY INTERVENTION STILL A SAFE AND EFFECTIVE OPTION

Abstract

Objective: To study the results and complications of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) of native coronary arteries at a newly established cardiac hospital.

Study Design: Retrospective case studies from hospital database.

Place and Duration of Study: This retrospective study was done at Army Cardiac Centre, Lahore, January
2009 to January 2014 (Five years initial experience).

Patients and Methods: Army Cardiac Centre Lahore is a tertiary care cardiac hospital with state of the art
cardiac catheterization laboratories, cardiac operation theatres and attached facilities. The duration of this
study has covered its initial 5 years of inception. PCI record of all the CTO’s were retrieved from the hospital
database and data was analyzed for different variables which included age, gender, duration of disease,
distribution of coronary lesions in CTO, number of successful angioplasties in different coronary arteries
having CTO, number of un-successful angioplasties in different coronary arteries having CTO, mortality, and
number of major acute coronary events.

Results: Out of a total of 1870 PCI’s performed, 210 (11%) had CTO. Males 177 (84.2%) dominated the study as
against 33 (15.8%) females. Age of the patients ranged from 31-90 years with a mean age of 60.5 years. Group I
of relatively younger age patients (31 – 70 years) had better success rate 153 (73%) as against Group II of

Conclusion: Although tedious and time consuming, PCI to CTO is a safe and effective option for
revascularization
