Long Inflation at Stent Deployment in Intravascular Ultrasound-Guided Percutaneous Coronary Intervention for Acute Myocardial Infarction.

ABSTRACT:

Background

There is a substantial risk of slow flow during percutaneous coronary intervention (PCI) for the culprit lesion in acute myocardial infarction (AMI), which can lead to adverse outcomes. We hypothesized that single-step long balloon inflation during stent deployment was associated with a more favorable final Thrombolysis in Myocardial Infarction (TIMI) flow grade. This retrospective study aimed to compare both the final TIMI flow grade and the delta TIMI flow grade in intravascular ultrasound (IVUS)-guided PCI for AMI between patients with long balloon inflation and those with conventional inflation.

Methods and results

Long inflation was defined as single-step inflation ≥60 s at stent deployment. The primary endpoints were achievement of the final TIMI flow grade
