Is this trial a fit for you?

Likely a good fit

Adults aged 18-85 with complex coronary disease undergoing PCI.

Probably not a fit

Patients with straightforward coronary disease or those without intraprocedural complications may have little relevance to the study’s questions.

What this trial studies

This observational study examines complex coronary artery disease patients who undergo PCI to see if non-fatal intraprocedural complications are associated with increased long-term mortality. Complex lesion types include chronic total occlusions, ostial epicardial lesions, diffuse disease, severe calcification, true bifurcations, left main disease, high thrombus burden, and in-stent restenosis. Non-fatal complications of interest include abrupt vessel occlusion, reduced TIMI flow, major dissections, thrombus formation, vessel perforation, malignant arrhythmias, stroke or TIA, and major non-coronary bleeding. The goal is to describe relationships between these intraprocedural events and late mortality after complex PCI.

Why it matters

Potential benefit: If associations are found, clinicians may better identify patients at higher risk of late death and tailor follow-up accordingly.

How similar studies have gone: Previous work in complex PCI has explored intraprocedural events, with some evidence suggesting links to outcomes, though detailed associations with non-fatal events require further clarification.
