Surgical and percutaneous coronary artery intervention revascularization are traditionally considered isolated options. A simultaneous hybrid approach may allow an opportunity to match the best strategy for a particular anatomic lesion. Concerns regarding safety and feasibility of such an approach exist. We examined the safety, feasibility, and early outcomes of a simultaneous hybrid revascularization strategy (minimally invasive direct coronary bypass grafting of the left anterior descending [LAD] artery and drug-eluting stent [DES] to non-LAD lesions) in 13 patients with multivessel coronary artery disease that underwent left internal mammary artery to LAD minimally invasive direct coronary bypass performed through a lateral thoracotomy, followed by stenting of non-LAD lesions, in a fluoroscopy-equipped operating room. Assessment of coagulation parameters was also undertaken. Inhospital and postdischarge outcomes of these patients were compared to a group of 26 propensity score matched parallel controls that underwent standard off-pump coronary artery bypass. Baseline characteristics were similar in both groups. All hybrid patients were successfully treated with DES and no inhospital mortality occurred in either group. Hybrid patients had a shorter length of stay (3.6 +/- 1.5 vs 6.3 +/- 2.3 days, P < .0001) and intubation times (0.5 +/- 1.3 vs 11.7 +/- 9.6 hours, P < .02). Despite aggressive anticoagulation and confirmed platelet inhibition, hybrid patients had less blood loss (581 +/- 402 vs 1242 +/- 941 mL, P < .05) and decreased transfusions (0.33 +/- 0.49 vs 1.47 +/- 1.53 U, P < .01). Six-month angiographic vessel patency and major adverse cardiac events were similar in the hybrid and off-pump coronary artery bypass groups. A simultaneous hybrid approach consisting of minimally invasive coronary artery bypass grafting with left internal mammary artery to LAD combined with revascularization of the remaining coronary targets using percutaneous coronary artery intervention with DES is a feasible option accomplished with acceptable clinical outcomes without increased bleeding risk.
传统上,外科手术和经皮冠状动脉介入血管重建被视为独立的选择。同步混合方法可能提供一个机会,以匹配针对特定解剖病变的最佳策略。人们对这种方法的安全性和可行性存在担忧。我们研究了13例多支冠状动脉疾病患者采用同步混合血管重建策略(左前降支[LAD]动脉的微创直接冠状动脉搭桥术和非LAD病变的药物洗脱支架[DES])的安全性、可行性和早期结果。这些患者通过侧胸壁切口进行左乳内动脉至LAD的微创直接冠状动脉搭桥术,随后在配备荧光透视的手术室中对非LAD病变进行支架置入。同时还进行了凝血参数评估。将这些患者的住院和出院后结果与一组26例倾向评分匹配的平行对照进行比较,这些对照接受了标准的非体外循环冠状动脉搭桥术。两组的基线特征相似。所有混合手术患者均成功接受DES治疗,两组均未发生住院死亡。混合手术患者的住院时间较短(3.6±1.5天对6.3±2.3天,P<.0001),插管时间较短(0.5±1.3小时对11.7±9.6小时,P<.02)。尽管进行了积极的抗凝和确认的血小板抑制,混合手术患者的失血量较少(581±402毫升对1242±941毫升,P<.05),输血次数减少(0.33±0.49单位对1.47±1.53单位,P<.01)。混合手术组和非体外循环冠状动脉搭桥组的6个月血管造影血管通畅率和主要不良心脏事件相似。由左乳内动脉至LAD的微创冠状动脉搭桥术与使用DES的经皮冠状动脉介入对其余冠状动脉靶点进行血管重建组成的同步混合方法是一种可行的选择,可实现可接受的临床结果,且不会增加出血风险。
