Conduction disturbance after TAVR raises mortality risk
These patients need close follow-up, warn researchers
Conduction disturbances after transcatheter aortic-valve replacement (TAVR) are associated with increased mortality and other adverse outcomes, according to a systematic review and meta-analysis.
New-onset persistent left bundle branch block (NOP-LBBB), high-degree atrioventricular block leading to permanent pacemaker implantation and other conduction disturbances are the most frequent complications of TAVR. But the clinical impact of these disturbances remains controversial.
