Joseph balloon mitral valvuloplasty is a single balloon procedure for severe symptomatic mitral stenosis. We present a case where difficulty was encountered in advancing the balloon catheter across the mitral valve by standard technique. As the left atrium was grossly dilated, every time the balloon was tracked over the 0.035" extra support wire placed in left ventricle, the wire prolapsed into left atrium. A modified method wherein the balloon was maneuvered into left ventricle with the support of 14F long introducer sheath is presented. This step is useful to complete balloon mitral valvuloplasty successfully in subset of patients with giant left atrium.
约瑟夫球囊二尖瓣成形术是针对严重症状性二尖瓣狭窄的单球囊手术。我们报告一例采用标准技术将球囊导管推进穿过二尖瓣时遇到困难的病例。由于左心房明显扩张，每次将球囊沿置于左心室的0.035英寸超硬导丝推送时，导丝都会脱垂至左心房。本文介绍了一种改良方法，即在14F长穿刺鞘的支撑下将球囊送入左心室。这一步骤对于在左心房巨大的部分患者中成功完成球囊二尖瓣成形术很有用。
