What are the procedural and in-hospital outcomes of CTO-PCI in a South Asian population?
CTO-PCI can be performed with a high success rate (91%) in a South Asian population despite a high prevalence of complex lesions.
This retrospective study evaluated angiographic, procedural, and in-hospital outcomes of chronic total occlusion percutaneous coronary intervention (CTO-PCI) at Aga Khan University Hospital, Karachi, Pakistan, from January 2020 to December 2022. Among 55 patients with at least one identified CTO, 38 presented with low left ventricular ejection fraction (LVEF) and 17 with normal LVEF. Despite a high prevalence of complex lesions (elevated J-CTO scores), the procedure was successful in 50 cases (91%). There were no significant diffe-rences in outcomes between successful and unsuccessful CTO-PCI cases relative to the studied variables. Key Words: Chronic total occlusion, Left ventricular ejection fraction, Percutaneous coronary intervention outcomes.
Khan et al. (2026) conducted an observational in Chronic total occlusion (n=55). Chronic total occlusion percutaneous coronary intervention (CTO-PCI) vs. Unsuccessful CTO-PCI was evaluated on Procedural success. Chronic total occlusion percutaneous coronary intervention achieved a 91% procedural success rate (50 of 55 cases) despite a high prevalence of complex lesions.
