Efficacy of one-stop hybrid revascularization for treatment of unprotected left main coronary artery disease / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy of one-stop hybrid coronary revascularization [simultaneous minimally invasive direct coronary artery bypass surgery (MIDCAB) and percutaneous coronary intervention (PCI) procedures performed in an enhanced (or called "hybrid") operative unit] for the treatment of unprotected left main coronary artery (ULMCA) disease.</p><p><b>METHODS</b>From June 2007 to April 2009, 14 patients [13 male, mean age (60.4 +/- 15.4) years] underwent the one-stop hybrid approach in the "hybrid" operating room. Proximal lesions were evidenced in 5 patients and distal or bifurcation lesions in 11 patients. MIDCAB procedure for grafting of the left intramammary artery (LIMA) with the left anterior descending (LAD) artery was first performed via lower partial ministernotomy on the beating heart, followed by PCI on the LMCA disease and non-LAD coronary lesions.</p><p><b>RESULTS</b>Operation was successful in all patients underwent the one-stop hybrid procedure. LIMA grafts were used in all 14 patients and confirmed to be patent by angiography. A total of 25 non-LAD coronary lesions were treated by PCI and 29 stents (27 drug-eluting stents and 2 bare-mental stents) were implanted to 23 lesions and coronary angioplasty was performed in the remaining lesions. There was no death, perioperative myocardial infarction, stroke or repeat revascularization during the procedure and the follow-up period. All the patients remained free from angina during the 7.9 months (range 1 - 15 months) follow-up period. LIMA grafts and stents were patent in 5 patients at 1-year follow-up.</p><p><b>CONCLUSIONS</b>Our initial experience demonstrates that one-stop hybrid coronary revascularization provides a reasonable, feasible and safe alternative for selected patients with LMCA diseases.</p>
