Conduction abnormalities post alcohol septal ablation for hypertrophic cardiomyopathy - a single center experience

Indian Heart J. 2021 Oct 21:S0019-4832(21)00224-8. doi: 10.1016/j.ihj.2021.10.005. Online ahead of print.ABSTRACTConduction abnormalities are commonly noted after alcohol septal ablation(ASA). This was a retrospective, observational study where we studied the incidence of new onset conduction abnormalities post ASA. 23 patients, who underwent ASA over a period of 5 years, were included in the study. Baseline conduction abnormalities were noted in 26% patients(n=6). Transient complete heart block(CHB) was noted in 21.7%(n=5) whereas new onset right bundle branch block (RBBB) was seen in 60.8%(n=14). Left bundle branch block was uncommon(4.3%,n=1). Permanent pacemaker implantation was done in 4.3% (n=1) for CHB. Conduction anomalies are frequent after ASA with RBBB being most common.PMID:34688620 | DOI:10.1016/j.ihj.2021.10.005
