Fatal coronary artery spasm triggered before transseptal puncture for mitral transcatheter edge-to-edge-repair: a case report

BACKGROUND: Transient ST-segment elevation or coronary artery spasm during transseptal catheterization has been previously described. Most cases were either reversible or asymptomatic. CASE SUMMARY: We present a case of severe multiple coronary artery spasms with advanced atrioventricular block and...

Sumario:BACKGROUND: Transient ST-segment elevation or coronary artery spasm during transseptal catheterization has been previously described. Most cases were either reversible or asymptomatic. CASE SUMMARY: We present a case of severe multiple coronary artery spasms with advanced atrioventricular block and ventricular fibrillation during compression of the fossa ovalis by a sheath catheter, before the performance of the transseptal puncture procedure for mitral transcatheter edge-to-edge-repair. DISCUSSION: The mechanical effects of forward tension from transseptal puncture on the interatrial vagal network could be the most possible explanation for the occurrence of this phenomenon.
