Koroner kusp kaynaklı prematüre ventriküler komplekslerin kateter ablasyonu sonrası ortaya çıkan aort kapak yetmezliği sıklığı

Abstract

Aims: There are conflicting results about the effect of radiofrequency catheter ablation (RFA) of aortic cusp premature ventricular complexes (PVCs) on aortic valve regurgitation (AR). We aimed to investigate the effect of aortic valve function and integrity of RFA of coronary cusp PVCs. Methods: This cross-sectional study included 54 patients who underwent RFA of the aortic cusp region within the specified indications. Basal echocardiography was performed at baseline and 3 months after radiofrequency catheter ablation of aortic cusp PVCs. An increase of more than 1 degree in AR was considered significant. Results: The mean age of the patients was 44.6±12.0 years and the male gender ratio was 42.6%. On 24-hour rhythm holter monitoring, the mean VES burden was 21.5%, of which 12.9% were right coronary cusp (RCC), 59.3% left coronary cusp (LCC), and 27.8% RCC-LCC junction. Total procedure time was 136.9±33.2 minutes and RFA time was 14.9±11.4 minutes. When pre- and post-ablation parameters were compared, left ventricular ejection fraction was found to be higher after the procedure than before the procedure (p0.05). Conclusion: There was no increase in the degree of AR as a procedure-related complication and no significant AR was determined in patients who underwent RFA for PVCs in the aortic cusp region. Therefore, it can be concluded that VES ablations in the aortic cusp region are safe for the development of AR.
