[Rupture of the posterior wall of the left ventricle after mitral valve prosthesis].
Rupture of the posterior wall of the left ventricle after mitral valve prosthetics is a rare (0.6%) but a dangerous and death-threatening complication. Injury to the fibrous ring in the anatomically hazardous zone (at 4-5 o'clock of an imaginary clock-face) is the most frequent cause of the ruptures. Surgical correction of this complication will be successful only with the use of extracorporeal circulation and repeated cardioplegia. Preservation of the posterior cusp and subvalvular apparatus is a reliable measure preventing rupture of the posterior wall of the left ventricle.
