Objective We evaluated the initial results of a fast-track discharge protocol for patients undergoing minimally invasive transmyocardial revascularization (MiTMR). Methods Fifteen male patients, aged 64.5 ± 9.2 years, with an ejection fraction of 46.8% ± 9.9%, underwent MiTMR through a mini-left anterior thoracotomy aided by robotic-controlled thoracoscopic assistance. A postoperative management protocol included immediate extubation, early chest tube and pulmonary artery catheter removal, and mobilization within 12 hours. Results There were no operative arrhythmias or in-hospital mortalities. Three of 15 patients developed left lower lobe atelectasis, delaying discharge between 2 and 5 days. Overall hospital length of stay was 1.4 ± 1.2 days, although 12 of 15 patients (80%) were discharged to home in 23 hours. Mild-moderate cardiomyopathy (ejection fraction 30%–50%) was not associated with prolonged length of stay. Mean hospital profit margin was $1882.50. One 30-day readmission occurred on day 23 for rapid atrial fibrillation, and one death occurred on day 11. Conclusions Despite these high-risk patients having end-staged, ischemic coronary artery disease, most MiTMR patients can be discharged to home in less than 24 hours. Perioperative morbidity and mortality rates are relatively low, and hospital profit margins are modest.

We hypothesized that pretreatment of an infarcted heart by mechanical transmyocardial revascularization (TMR) before transplantation of bone marrow cells (BMCs) or BMC-expressing angiogenic growth factors would increase transplanted BMC survival and enhance myocardial repair. Female Lewis rats underwent coronary ligation 3 wk before creation of 10 needle TMR channels (3 groups) or no TMR (3 groups), followed by transplantation of 3 × 106 male donor BMCs, BMC transfected with vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and insulin-like growth factor-1 (IGF-1) (BMC + VBI), or medium alone. At 1, 3, and 7 days, we evaluated transplanted cell survival, vascular densities, and left ventricular (LV) function ( N = 4 per group × 6 groups × 3 time points). At 3 days, vascular densities in the scar were increased by TMR + BMC + VBI and by BMC + VBI ( P < 0.05), and at 7 days, vascular densities were greatest in rats receiving TMR + BMC + VBI ( P < 0.05). Transplanted cell survival at 3 and 7 days was increased by TMR and by BMC + VBI. Combined therapy with TMR + BMC + VBI resulted in the greatest cell survival at 3 days ( P < 0.05) versus BMC. After 7 days, LV ejection fraction (LVEF) was lowest in rats receiving neither BMC nor TMR and greatest in rats receiving TMR + BMC + VBI ( P = 0.004). We concluded that mechanical pretreatment of infarcted myocardium by TMR enhances the effect of subsequent cell-based gene therapy on transplanted cell survival, angiogenesis, and LV function. Scar pretreatment with TMR combined with cell-based multigene therapy may maximize myocardial repair.
