ABSTRACT
Objective To summarize the clinical experience of "One-stop" hybrid procedure that performs minimally in-vasive direct coronary artery bypass ( MII)CAB ) and percutaneous coronary intervention ( PC! ) concurrently on 35 patients with multivessel coronary artery disease (CAD). Methods Between June 2007 and May 2008, 35 patients [33 men and 2women, mean age (63.5±9.2) years] with multivessel CAD ( two-vessel CAD, n = 19; three-vessel CAD, n = 16, left main coronary artery disease, n = 7 ; coronary artery lesions, 2.5 lesions per patient) underwent "one-stop" hybrid procedure. The hybrid strategy was performed as a primary MIDCAB procedure for bypassing the left internal mammary artery ( LIMA ) to the left anterior descending artery ( LAD ), simultaneously followed by PCI ( pereutaneous transluminal coronary angioplasty (PTCA) and/or stenting) on the remaining non-LAD vessels. Concomitant diseases included hypertention in 20 patients, hy-perlipemia in 12 patients, previous myocardial infarction (MI) in 10 patients, diabetes mellitus (type 2) in 9 patients, previ-ous cerebrovascular disease in 2 patients, chronic obstructive pulmonary disease (COPD) in 1 patient, renal dysfunction in 1 patient, and ostium secundum atrial septal defect in 1 patient. The left ventricular ejection fraction (LVEF) averaged 0. 62±0.07. Results There were no reexploration for bleeding, strokes, myocardial infarctions, acute renal dysfunctions, or deaths in hospetal. Of the total 35 patients, 34 patients (97.1%) were successfully treated with "one-stop" hybrid procedure, and 1 patient (2.9%) was converted to conventional coronary artery bypass grafting ( CABG ) because of dissection of one obtuse marginal branch during PCI. One of the LIMA-LAD grafts was confirmed to be anastomotic stenosis by followed coronary angiog-raphy and was corrected immediately. The patient with ostium secundum defer underwent tranesophageal echocardiography guiding transcatheter closure after LIMA-LAD anastomosis. Catheter-based interventions were carried out in 61 coronary le-sions, including PTCA in 6 lesions and implantation of 62 drug-elating stents (DES) in the rest appropriate lesions. The mean number of DES implantation was 1.8 per patient, and the average diameter and length of implanted DES were respectively ( 3.2±0.5 )mm and 37.3 mm per patient. Of the 34 patients receiving hybrid procedure, the average mechanical ventrilation time was ( 10.8±7.9) hours, and 4 ( 11. 8% ) pateints were extubated in the operating room; length of stay in the intencive care unit averaged (33.6±33.0) hours and hospital stay (9±3) days; 24 patients (70.6%) avoided transfusion require-ment. Conclusion Our findings indicate that in high-risk patients with multivessel CAD, the "one-stop" hybrid procedure by performing MIDCAB and PCI simultaneously is a feasible and safe alternative.
