Tóm tắt

 BACKGROUND: Cardiac tamponade complicating transcatheter aortic valve replacement (TAVR) typically results from right ventricular (RV) injury induced by a pacemaker electrode, left ventricular (LV) injury induced by guidewires and catheters used during the procedure, and rupture of the aortic annulus during valve implantation. METHODS: We retrospectively analysed our institutional TAVR database to gain mechanistic insights relating to this complication. RESULTS: A total of 1247 TAVR procedures were performed from 2010 to 2024. Cardiac tamponade complicated 21 (1.7%) of these procedures. There was a nonsignificant reduction in occurrence of tamponade (1.9% among the first 623 cases vs 1.4% among the subsequent 624 cases
  CONCLUSIONS: Periprocedural cardiac tamponade during TAVR may be caused by various mechanisms. Careful guidewire manipulation may decrease occurrence of LV perforation.
