Closure of the atrial septal defect and replacement of the mitral valve was performed in a 56-year-old female with an unusual presentation of intermittent severe mitral insufficiency.
Case Report (n=1)
Describes a rare case of intermittent severe mitral insufficiency caused by a billowing anterior mitral leaflet associated with an atrial septal defect, treated with surgical closure and valve replacement.
May alert clinicians to ASD in intermittent mitral regurgitation; leaves open prevalence and management questions.
An unusual case of atrial septal defect secundum type, associated with intermittent severe mitral insufficiency due to billowing anterior mitral leaflet, in a 56-year old female is described. The degree of mitral insufficiency ranged from severe to none. This phenomenon manifested itself by an intermittent systolic apical thrill and intermittent mitral regurgitation on angiocardiography. Pulling the anterior mitral leaflet at operation through the atrial septal defect demonstrated that this leaflet could be caught in the left atrium, thus causing intermittent mitral insufficiency. Closure of the atrial septal defect and replacement of the mitral valve was performed.

Friedensohn et al. (1979) conducted a case report in Atrial septal defect secundum type with intermittent severe mitral insufficiency (n=1). Closure of the atrial septal defect and replacement of the mitral valve was evaluated. Closure of the atrial septal defect and replacement of the mitral valve was performed in a 56-year-old female with an unusual presentation of intermittent severe mitral insufficiency.
