Takotsubo cardiomyopathy complicating transcatheter mitral valve-in-valve replacement

摘要

A 73-year-old female presented with symp-tomatic heart failure(NYHA class Ⅲ)due to a failed 29-mm Sorin(St.Jude Medical,St.Paul,MN)bioprosthetic heart valve surgically implanted 10-year before for severe primary mitral valve regurgitation(flail of the anterior mitral leaf-let at A2 scallop).Preprocedural echocardiography showed preserved left ventricular function with severe bioprosthetic valve stenosis and concomit-ant moderate regurgitation(Video 1 in Supplement).Because of prohibitive surgical risk,a transeptal mitral valve-in-valve(ViV)replacement was planned.
