Abstract:
Objective To summarize clinical results of 29 cases of multi-vessel coronary disease treated by hybrid revascularization.Methods A total of 29 consecutive patients(all male,aged 62.8?9.7 years) with coronary artery disease(two-vessel,n=10;three-vessel,n=19) were treated with minimally invasive direct coronary artery bypass(MIDCAB)(left internal mammary artery to left anterior descending artery,LIMA-to-LAD) and percutaneous coronary intervention(PCI) between January 2000 and April 2005.The left ventricular ejection fraction(LVEF) was 0.576?0.108.Concomitant diseases included hypertension in 23 patients,insulin-dependent diabetes mellitus in 5 patients,chronic obstructive pulmonary disease in 2 patients,and old myocardial infarction in 14 patients.Results The 29 patients received 33 grafts(LIMA: 27 grafts;great saphenous vein: 6 grafts).Balloon angioplasty was carried out in 41 coronary lesions,usually following surgery.The mean number of revascularization was 2.5 per patient.There was no surgery-related complications and mortality.The blood flow in the LIMA was 45?14 ml/min.The chest drainage volume was 274?197 ml.Blood transfusion was required in 2 patients(6.9%).The length of ICU stay was 1.9?0.1 d and the length of hospital stay was 4~11 d(mean,7.5 d).Follow-up for 2.2?0.9 years showed no late death and myocardial infarction.Postoperative New York Heart Association(NYHA) Classification showed Class Ⅰ in 25 patients and Class Ⅱ in 4 patients.Repeated angiography was conducted in 4 patients,which found great saphenous vein graft occluded in 1 patient and stent re-stenosis in 2 patients.Conclusions The midterm results of hybrid techniques for coronary artery disease are satisfactory.Hybrid procedure is beneficial to high-risk patients.The long-term results need further investigation.
