Ostial and midshaft lesions vs. bifurcation lesions in 1111 patients with unprotected left main coronary artery stenosis treated with drug-eluting stents: results of the survey from the Italian Society of Invasive Cardiology.

Aims: In this study, we compared the cumulative risk of major adverse cardiac events (MACE) of patients with distal unprotected left main coronary artery (ULMCA) stenosis with those of patients with ostial and midshaft lesions treated with drug-eluting stent (DES).

Methods And Results: The survey promoted by the Italian Society of Invasive Cardiology on ULMCA stenosis was an observational study involving 19 high-volume Italian centres. We enrolled 1111 patients with ULMCA stenosis treated with DES.

A comparison between coronary artery bypass grafting surgery and drug eluting stent for the treatment of unprotected left main coronary artery disease in elderly patients (aged > or =75 years).

Aims: In this study, we compared the clinical outcomes of elderly patients with unprotected left main coronary artery (ULMCA) stenosis treated with either coronary artery bypass grafting (CABG) or drug-eluting stent (DES).

Methods And Results: From January 2003 to April 2006, 259 patients with ULMCA stenosis and age > or =75 years underwent coronary revascularization with either CABG or DES. One hundred and sixty-one patients were treated with CABG and 98 with DES.
