Incidence and Risk Factors for Permanent Pacemaker Implantation Following Mitral or Aortic Valve Surgery.

ABSTRACT:

Background

Risk factors for post-operative conduction disturbances after cardiac valve surgery requiring a permanent pacemaker (PPM) are poorly characterized.

Objectives

The aim of this study was to investigate the timing and risk factors for PPM implantation after mitral or aortic valve surgery.

Methods

All patients who underwent open aortic or mitral valve surgery between January 1996 and December 2014 were reviewed using New York State's mandatory hospital discharge database. Patients with prior cardiac surgery or pre-existing PPM were excluded. The primary endpoint was PPM implantation within 1 year.

Results

Among 77,882 patients, 63.8% (n = 49,706) underwent aortic valve replacement (AVR), 18.9% (n = 14,686) underwent mitral valve replacement (MVR), 10.5%
