Abstract

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditis of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditis initially mistaken diagnosis of cystic mass, which was confirmed at operation with successful mitral valve annuloplasty.

Figure

• 

  Fig. 1 A fluttering perforated cystic mass (1.3 × 1.6 cm, white arrow) in left atrium attached to the posterior mitral valve leaflet in the parasternal long axis view (A) and apical 4 chamber view (B), which resulted in poor coaptation and opening of mitral valve.

• 

  Fig. 2 The color Doppler flow showed that the cystic mass was filled with flow during systole (white arrow, A) and also the color flow in the cystic mass was communicated with the left atrium (white arrow, B). Continuous wave Doppler revealed that the mass caused hemodynamic disturbance and there was moderate increase of mean pressure gradient (C).

  Fig. 3 The specimen of the resected mitral valve aneurysm with a white thin wall (24 × 17 × 14 mm).
