Impact of Intravascular Ultrasound Guidance on Long-Term Mortality in Stenting for Unprotected Left Main Coronary Artery Stenosis.

The article discusses a study which compared the long-term outcomes of intravascular ultrasound (IVUS)-guided stenting and conventional angiography-guided stenting for unprotected left main coronary artery stenosis. To assess the differential effectiveness of IVUS in the placement of drug-eluting stent (DES) and bare-metal stent (BMS) the outcomes were also stratified. Findings suggest that when compared with conventional angiography guidance, elective stenting with IVUS guidance may reduce long-term mortality rate.
