Key result
AVR plus tricuspid repair triggers spontaneous resolution of severe secondary MR without mitral intervention.
Why the study?
Instant spontaneous resolution of severe secondary mitral regurgitation after surgical correction of aortic regurgitation causing left ventricular volume overload is not well documented.
Case Report (n=1)
Instant spontaneous resolution of secondary mitral regurgitation is possible after surgical correction of aortic regurgitation causing left ventricular volume overload.
Secondary MR may resolve spontaneously after AVR in multivalvular disease; leaves open whether mitral intervention can be safely deferred.
We present the case of a patient with infective endocarditis anesthetized for replacement of severely regurgitant aortic valve. Intraoperative transesophageal echocardiography revealed a new diagnosis of severe secondary mitral regurgitation. After aortic valve replacement and tricuspid valve repair, severe mitral regurgitation resolved rapidly without any intervention. In multivalvular disease, instant spontaneous resolution of secondary mitral regurgitation is possible after surgical correction of an aortic regurgitation causing left ventricular volume overload.

Friess et al. (2021) conducted a case report in Infective endocarditis with severe aortic and secondary mitral regurgitation (n=1). Aortic valve replacement and tricuspid valve repair was evaluated on Resolution of severe secondary mitral regurgitation. Aortic valve replacement and tricuspid valve repair led to the rapid, spontaneous resolution of severe secondary mitral regurgitation without direct intervention on the mitral valve.
