Interlayer dissection of the atrial septum resulting in the formation of a cavity developed after an attempted repair of a mitral paraprosthetic leak. Subsequent rupture of the cavity into both atria resulted in a small left-to-right shunt and significant left ventriculoatrial regurgitation. Misplaced stitches, aimed at obliterating the paraprosthetic leak, were the cause of the dissection. This case illustrates a previously unreported complication of mitral valve surgery and stresses the importance of proper exposure and handling of the mitral annulus.
二尖瓣人工瓣膜旁漏修补术尝试后，房间隔层间剥离导致形成一个腔隙。随后该腔隙破裂至双侧心房，导致少量左向右分流及显著的左心室-心房反流。旨在消除人工瓣膜旁漏的缝线位置不当是剥离的原因。本病例说明了二尖瓣手术一种此前未报道的并发症，并强调了二尖瓣环适当暴露和处理的重要性。
