Severe haemolytic anaemia and acute renal failure caused by pinhole perforation of native mitral valve: a case report
A prior study suggested the presence of subclinical intravascular haemolysis in patients with primary MR. In the present case, an accelerated MR jet through a pinhole perforation, in addition to a jet directed against the atrial wall, appears to have caused clinically significant haemolysis. This case highlights that native mitral valve perforation can induce mechanical haemolysis in a manner similar to that seen following mitral valve surgery.
