Schaff et  al (J Am Coll Cardiol 2019;74:645, PMID 31370956) evaluated the impact of conduction abnormalities on mortality in patients with obstructive hypertrophic cardiomyopathy after myectomy. The morality of 2482 patients with septal myectomy were analyzed. The mean age at operation was 54.2 ± 14.6 year s, and 1370 patients (55.2%) were men. Preoperatively, 2159 patients (87.0%) had normal conduction. Postoperatively, 38.8% developed left bundle branch block (LBBB), 1.1% developed right bundle branch block (RBBB), and 0.6% had complete heart block (CHB).
