AI Article Synopsis
- The study examined the incidence of new conduction abnormalities after alcohol septal ablation (ASA) in 23 patients over 5 years.
- Pre-existing conduction issues were found in 26% of patients, while new onset right bundle branch block (RBBB) occurred in 60.8% of cases, and transient complete heart block (CHB) was noted in 21.7%.
- Permanent pacemaker implantation was required in 4.3% of patients, indicating that conduction abnormalities after ASA are common, with RBBB being the most frequently observed issue.
Article Abstract
Conduction 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.
