ABSTRACT

A patient with advanced rheumatic heart valve disease underwent aortic and mitral valve replacement with tricuspid ring annuloplasty. There was an anomalous left circumflex coronary artery (LCCA) arising from the right coronary artery (RCA) running along the anterior surface of an enlarged right ventricle (RV). During the immediate postoperative course, signs of inferior and lateral myocardial ischemia developed. An emergent coronary angiography revealed LCCA entrapment. An additional suture placed in the RV outflow tract used to optimize exposition of the aortic root during the aortotomy was determined to be the origin of the coronary entrapment. No similar case of LCCA occlusion has previously been reported. This is a description of successful management of this complication.

ABSTRACT

A 52-year-old male patient, who underwent mitral replacement with a mechanical prosthesis as a child, sustained a cardiac arrest which was successfully resuscitated. Further investigation showed prosthesis malfunction with significant regurgitation in the context of multi-organ failure. In such a life-threatening condition, veno-arterial extracorporeal membrane oxygenation was considered as a rescue procedure to achieve optimisation of clinical status to allow definitive surgical treatment. An unusual complete fracture of the prosthesis was subsequently identified as the cause of acute dysfunction.

ABSTRACT

A patient who underwent previous implantation of a mitral valve replacement with a Björk-Shiley Delrin (BSD) mitral valve prosthesis during infancy was admitted to our institution 43 years later after an episode of syncope and cardiac arrest. Under extreme hemodynamic instability, a mitral valve prosthetic dysfunction causing massive mitral regurgitation was identified. The patient underwent an emergent cardiac operation, and a complete disc fracture with partial disc migration was found. Exceptional cases of mechanical prosthetic heart valve fracture exist. We report the first case of complete transversal disc rupture of a BSD mitral valve prosthesis after the longest period of implantation ever reported in that position.
