Why the study?
TTCP can lead to right ventricular wall penetration or perforation, but no study had analyzed its effect on myocardial injury by cardiac troponin measurement.
Does temporary transvenous cardiac pacing cause myocardial injury in patients undergoing noncardiac procedures?
Does temporary transvenous cardiac pacing cause myocardial injury in patients undergoing noncardiac procedures?
Elective temporary transvenous cardiac pacing for noncardiac procedures is associated with significant perioperative myocardial injury as evidenced by cardiac troponin elevation.
INTRODUCTION: Temporary transvenous cardiac pacing (TTCP) can lead to potential penetration and occasional perforation of the right ventricular wall. No study to date has analyzed the effect of TTCP on myocardial injury by cardiac troponin (cTn) measurement. The present study was designed to investigate perioperative myocardial injury in elective TTCP in noncardiac surgical settings. PATIENTS AND METHODS: This retrospective study investigated the data collected from August 2018 through March 2020 from 22 eligible patients who underwent elective TTCP for noncardiac procedures. The patients had a median age of 66 (50-83) years; six (27.3%) of them were women, and all of them had a baseline cTn <1 upper reference limit (URL). Cardiac biomarker assays were performed before and after TTCP, and their results were compared. CONCLUSION: The study demonstrates a high incidence of myocardial injury associated with TTCP, which should be a matter of concern for the involved physicians.
