本研究是为了验证双侧背阔肌心肌成形术比单侧手术提供更大的血流动力学增强的假设。对8只杂种犬分别进行了两种类型的双侧手术和左后心肌成形术。用可编程脉冲刺激器实现r波同步肌肉起搏。使用配对试验比较受刺激心跳与非受刺激基线的血流动力学变量。双前肌包裹的效果与右前/左后配置相同。因此，我们将两种双侧手术的数据结合起来，并与左侧包裹术进行比较。双侧心肌成形术刺激导致右心室压（44±3.1 vs 26±1.8）、右心室压一阶导数（595±117 vs 196±14）、肺动脉压（34±1.9 vs 23±1.6）、左心室压（90±5.9 vs 69±5.3）、左心室压一阶导数（1454±141 vs 1072±107）、主动脉压（80±5.4 vs 67±4.9）显著升高。主动脉血流峰值（9.4±1.1比7.7±0.8），差异有统计学意义（p< 0.05）。所有这些变量的显著增加也发生在左心肌成形术的刺激中，但右室压力、右室压力一阶导数、肺动脉压力和主动脉压力的增加在双侧比左心肌成形术更大。双侧和左侧手术均可增强收缩期心室功能。双侧手术似乎有更大的影响，特别是对右心室功能。
This study was undertaken to test the hypothesis that a bilateral latissimus dorsi cardiomyoplasty provides greater hemodynamic augmentation than a unilateral procedure. Two types of bilateral procedure and a left posterior cardiomyoplasty were tested in each of 8 mongrel dogs. R-wave synchronous muscle pacing was achieved with a programmable burst stimulator. Hemodynamic variables of stimulated beats were compared with those of a nonstimulated baseline using pairedttests. The effects of a double anterior muscle wrap were equal to a right anterior/left posterior configuration. Therefore, the data on the two types of bilateral procedure were combined and compared with the left wrap. Stimulation of the bilateral cardiomyoplasty resulted in significant increases in right ventricular pressure (44 ± 3.1 versus 26 ± 1.8), first derivative of right ventricular pressure (595 ± 117 versus 196 ± 14), pulmonary artery pressure (34 ± 1.9 versus 23 ± 1.6), left ventricular pressure (90 ± 5.9 versus 69 ± 5.3), first derivative of left ventricular pressure (1454 ± 141 versus 1072 ± 107), aortic pressure (80 ± 5.4 versus 67 ± 4.9), and peak aortic flow (9.4 ± 1.1 versus 7.7 ± 0.8) (p< 0.05). Significant increases in all of these variables also occurred with stimulation of the left cardiomyoplasty, but the increases in right ventricular pressure, first derivative of right ventricular pressure, pulmonary artery pressure, and aortic pressure were larger for the bilateral than the left cardiomyoplasty. The bilateral and the left procedure can each augment systolic ventricular function. The bilateral procedure appears to have greater effects, especially on right ventricular function.
