In January 2020, the first Medtronic VDD leadless pacemaker Micra AV was approved by FDA to treat patients with advanced AV block, based on the encouraging results from the Micra Atrial tRacking using a Ventricular accELerometer 2 (MARVEL 2). There is reassuring data about safety and short‐term outcomes of traditional leadless pacemaker implant after recent surgical tricuspid valve replacement, but only few cases are reported in literature. No data was found regarding AV Micra implant safety and outcomes in patients following bioprosthetic tricuspid valve replacement as of today. Our patient is a 44‐year‐old gentleman with history of IV drug use who recently underwent tricuspid replacement with bioprosthesis for infective endocarditis complicated by postsurgical heart block, acute kidney insufficiency requiring hemodialysis, persistent bacteremia and candidemia, and progressive failure of the epicardial pacing wires. Given the elevated infective risk, the decision of attempting leadless pacer implant through the bioprosthetic valve was taken and our patient underwent successful Micra AV implant on postoperative day 30. To our knowledge, this is the first AV Micra placement following bioprosthetic tricuspid valve replacement. The uneventful procedure and the encouraging short‐term device follow‐up results seem to confirm the relative safety of this device in treating advanced atrioventricular conduction disorders in patients at elevated infective risk.
