Recovery of atrioventricular conduction after pacemaker placement following cardiac valvular surgery
Cardiac Pacing, Artificial
Cardiac Surgical Procedures
Approximately 40% of patients who received a PPM for AVB after valve surgery displayed no evidence of high-grade AVB during serial device interrogations. However, simple baseline demographic, operative, and postoperative variables are not sufficiently robust for discriminating those patients with early postoperative AVB who will not need long-term pacing following valve surgery.
