To evaluate the efficacy of left ventriculectomy, on a short term basis, as a treatment for patients with end-stage heart failure.
From February to June 1995, 7 patients with end-stage heart failure underwent partial left ventriculectomy. Before the surgical procedure, 7 (100%) patients were in functional class IV. Three (42%) patients needed inotropic support for hemodynamic stability. The mean daily dose of furosemide was l48.67 +/- 128.27 mg, of captopril 87.50 +/- 95.20 mg and of digoxin 0.23 +/- 0.04. Mean left ventricular diastolic dimension determined by 2-D echocardiography was 78.29 +/- 12.63 mm, mean left ventricular ejection fraction, determined by radionuclide ventriculography, was 0.15 +/- 0.05 whereas mean transpulmonary gradient and pulmonary vascular resistance in Wood units, determined by right heart catheterization, were 16.80 +/- 8.80 and 6.57 +/- 3.22, respectively.
Sixty days after the surgery, the mean functional class was 1.71 +/- 0.48 (p = 0.009), the mean left ventricular diastolic dimension 64.67 +/- 11.41 mm (p = 0.02) and the mean left ventricular ejection fraction 0.22 +/- 0.04 (p = 0.02).
The left ventriculectomy is a promising treatment for patients with end-stage heart failure.
短期评估左心室切除术治疗终末期心力衰竭患者的疗效。
1995年2月至6月,7例终末期心力衰竭患者接受了部分左心室切除术。手术前,7例(100%)患者心功能为IV级。3例(42%)患者需要使用正性肌力药物以维持血流动力学稳定。呋塞米的平均每日剂量为148.67±128.27毫克,卡托普利为87.50±95.20毫克,地高辛为0.23±0.04。二维超声心动图测定的平均左心室舒张末期内径为78.29±12.63毫米,放射性核素心室造影测定的平均左心室射血分数为0.15±0.05,而右心导管检查测定的平均跨肺压差和以伍德单位表示的肺血管阻力分别为16.80±8.80和6.57±3.22。
术后60天,平均心功能分级为1.71±0.48(p = 0.009),平均左心室舒张末期内径为64.67±11.41毫米(p = 0.02),平均左心室射血分数为0.22±0.04(p = 0.02)。
左心室切除术对于终末期心力衰竭患者是一种有前景的治疗方法。
