Percutaneous Coronary Intervention without onsite Cardiac Surgery Backup

Abstract

Introduction: Mechanical revascularization by percutaneous coronary interventions has now become an established and preferable method of revascularization in patients with acute coronary syndromes. The aim of the study was to identify the clinical indications for percutaneous coronary interventions and in-hospital outcomes of percutaneous coronary interventions in a tertiary-level hospital without onsite cardiac surgery backup. Methods: This was a prospective descriptive study. All consecutive patients who were admitted for percutaneous coronary interventions, including both primary as well as elective percutaneous coronary interventions, between March 2011 and December 2012 were included in the study. Results: Total 101 percutaneous coronary interventions were performed. The mean age was 58.9 ± 12.3 years. The most frequent indication was ST-elevation myocardial infarction 72 (71.3%). Proximal artery stenting were performed in 39 (38.5%) and the non proximal artery stenting in 62 (61.5%). The outcomes were mortality 5 (4.9%), periprocedural myocardial infarction 2 (1.9%), cardiogenic shock 6 (5.9%), contrast induced nephropathy requiring dialysis in 3 (2.9%), minor complications which were managed conservatively in 13 (12.9%). Conclusions: Percutaneous coronary intervention was feasible with acceptable complications in a tertiary-level hospital without onsite cardiac surgery backup. ST-elevation myocardial infarction was the major indication and cardiogenic shock was the major complication observed, and non proximal artery stenting was more common than the proximal artery stenting.
