The incidence of cardiac complications from atrial transseptal catheterization has never been quantified in patients with normal-sized atria. Series defining the complication rate are derived from diseased hearts with structural changes that may alter the complication rate of the procedure. The generation of a standardized incidence of perforation in a population of structurally normal atria has important implications. A total of 46 atrial transseptal catheterizations guided by transesophageal echocardiography (TEE) for radiofrequency ablation of left-sided accessory pathways was performed in 42 patients during a 3-year period (1990-1993). Clinical and echocardiographic data were analyzed, with special attention given to TEE reports pre- and post-transseptal catheterization. Only one complication occurred in the 46 procedures (2.2%): a perforation of the left atrium that led to pericardial effusion and cardiac tamponade. In a small series of patients with normal sized atria, we have demonstrated that TEE-guided transseptal catheterization in a procedure with a low complication rate.
在心房大小正常的患者中，经房间隔导管插入术引起心脏并发症的发生率从未得到过量化。确定并发症发生率的系列研究来自于存在结构改变的患病心脏，而这些结构改变可能会改变该手术的并发症发生率。在结构正常的心房人群中生成标准化的穿孔发生率具有重要意义。在1990年至1993年的3年期间，对42例患者进行了总共46次经食管超声心动图（TEE）引导下的房间隔导管插入术，用于左侧旁路途径的射频消融。对临床和超声心动图数据进行了分析，并特别关注经房间隔导管插入术前和术后的TEE报告。在这46例手术中仅发生了1例并发症（2.2%）：左心房穿孔，导致心包积液和心脏压塞。在一小系列心房大小正常的患者中，我们已证明TEE引导下的经房间隔导管插入术是一种并发症发生率较低的手术。
