Abstract
Background: Computed tomography coronary angiography(CTCA) can be useful in procedure planning for CTO PCI by identifying factors known to influence PCI success rates, such as calcification, severe tortuosity and length of the occluded segment. Percutaneous coronary intervention for CTO is considered to be one of the most challenging procedures of interventional cardiology, and in the earlier studies, successful recanalization rates of CTO ranged from 51% to 74%. However, with improved operator experience and the development of novel equipment and techniques, procedural success rates have been increased, which brings an increasing number of CTO into a treatable category.
Aim of the study: This study aimed at identification of MDCT coronary angiography findings that can predict the outcome of retrograde PCI upon chronic totally occluded coronary arteries.
Patients and Methods: The study is an exploratory pilot study that was conducted On 40 patients were performed using retrograde wire approach with various strategies by highly experienced CTO operators. In Ain Shams University hospitals and in Kobry Elkobba Military hospital from August 2015 to 2016
Results : Our study was performed on 40 CTO patients categorized into two groups, group (1) with successful retrograde PCI In 32 patients (80%) and group (2 ) with failure retrograde PCI 8 patients (20%).
