Abstract | AIMS: METHODS AND RESULTS: A total of 501 patients (mean age 74±8 years, 53% male) without preoperative cardiac conduction disturbances who underwent AVR or TAVI were included in the study. Su-AVR patients and TAVI patients had a higher incidence of new-onset LBBB at hospital discharge (23% and 16%, respectively) compared to patients treated with conventional AVR (4%; p<0.001). On multivariate logistic regression analyses, the type of AVR was independently associated with complete LBBB, after correcting for age, preoperative QRS duration and heart rate (su-AVR and TAVI relative to the reference category conventional AVR: odds ratio [OR] 8.5, 95% confidence interval [CI]: 3.7-19.5; p<0.001, and OR 5.8, 95% CI: 2.4-14.1; p<0.001, respectively). CONCLUSIONS: Su-AVR and TAVI were associated with higher risk of developing postoperative LBBB compared to conventional AVR, after adjusting for age, preoperative heart rate and QRS duration.
