A percutaneous left ventricular support (PLVS) system can play an important role in the short-term support of patients with severe heart failure, but these devices are not available for clinical use. We devised a new transseptal left atrial (LA) cannula for PLVS without thoracotomy. The cannula is 21 Fr in size (internal diameter: 5.3 mm) and 65 cm in length. This transseptal LA cannula can be inserted easily into the left atrium under fluoroscopy, by the usual transseptal technique, using a conventional Brockenbrough's needle. PLVS was used in two patients who developed cardiogenic shock following acute myocardial infarction and underwent resuscitation using percutaneous cardiopulmonary support (PCPS). The patients could not be weaned from PCPS even after successful percutaneous transluminal coronary angioplasty (PTCA), and PLVS provided 3.0 L/min of assist flow. The duration of PLVS was 114 and 92 hr. Both patients were weaned from PLVS, and one survived. There were no complications related to the PLVS. PLVS with a new transseptal LA cannula may be effective and useful for patients with severe heart failure.
经皮左心室支持（PLVS）系统在重度心力衰竭患者的短期支持中可发挥重要作用，但这些设备尚未用于临床。我们设计了一种无需开胸的用于PLVS的新型经房间隔左心房（LA）插管。该插管尺寸为21 Fr（内径：5.3 mm），长度为65 cm。这种经房间隔LA插管可在透视引导下，通过常规经房间隔技术，使用传统的布罗肯布罗针轻松插入左心房。PLVS用于两名急性心肌梗死后发生心源性休克并接受经皮心肺支持（PCPS）复苏的患者。即使在成功进行经皮腔内冠状动脉成形术（PTCA）后，患者仍无法撤离PCPS，而PLVS提供了3.0 L/min的辅助血流。PLVS的持续时间分别为114小时和92小时。两名患者均成功撤离PLVS，其中一名存活。未发生与PLVS相关的并发症。采用新型经房间隔LA插管的PLVS可能对重度心力衰竭患者有效且实用。
