The waffle procedure is performed in patients with marked thickening and calcification of the epicardium and no substantial improvement in hemodynamic parameters after pericardiectomy. We retrospectively investigated the efficacy of the waffle procedure in 6 of 11 patients who underwent pericardiectomy. These 6 patients showed no improvement in central venous pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure, or cardiac index after pericardiectomy. After the waffle procedure, all hemodynamic parameters improved, and there were no significant differences compared to those of the 5 patients who did not require the waffle procedure, despite higher pulmonary capillary wedge pressure and lower cardiac index values preoperatively in the waffle group. The waffle procedure was considered effective in patients with persistent epicardial constriction.
华夫手术适用于心包显著增厚和钙化且心包切除术后血流动力学参数无实质性改善的患者。我们回顾性研究了11例行心包切除术患者中6例接受华夫手术的疗效。这6例患者心包切除术后中心静脉压、肺动脉压、肺毛细血管楔压或心脏指数均无改善。华夫手术后，所有血流动力学参数均有改善，与5例不需要华夫手术的患者相比无显著差异，尽管华夫组术前肺毛细血管楔压较高且心脏指数较低。华夫手术被认为对持续性心包缩窄患者有效。
