Procedural Complications and Long-Term Mortality in Complex Coronary Interventions

Overview

The relative risks for different non-fatal intraprocedural complications during complex percutaneous coronary intervention (PCI) on subsequent mortality have not been described. This study aimed to assess the association between non-fatal intraprocedural complications and late mortality after complex coronary PCI.

Complex coronary lesions include chronic total occlusion, osteal epicardial lesions, long (diffuse) coronary disease, severe calcific lesions, true bifurcation disease, left main coronary lesion, lesions with severe thrombus, and in-stent restenosis. Non-fatal intraprocedural complications included abrupt occlusion, worsening of thrombolysis in myocardial infarction (TIMI) flow grade (TIMI \< 3), major dissection (greater than type B), occurrence of thrombus formation, perforation of the main vessel or side branch, malignant arrhythmias, stroke/transient ischemic attack, and non-coronary major bleeding.
