Left atrial wall thickness and outcomes of catheter ablation for atrial fibrillation in patients with hypertrophic cardiomyopathy

Abstract

The LA wall in the HCM patients with AF was not thicker than that of the matched patients without structural heart disease. Catheter ablation of AF showed favorable outcomes in both patient groups.

Catheter ablation for atrial fibrillation in hypertrophic cardiomyopathy: a systematic review and meta-analysis

“…Of these, 177 were excluded as they were either duplicates or deemed unsuitable for the purpose of the meta-analysis (editorials, letters, reviews or case reports). The remaining 32 studies were carefully screened and after analysis of their abstracts and/or full-text only [14][15][16][17][18][19][20][21][22][23][24][25][26][27] (one was a conference abstract 22 ) were considered adequate for inclusion in the systematic review (figure 1). Of these, only six studies, 16 19 22-25 provided enough details to be included in the meta-analysis.…”

Left Atrial Wall Thickness and Pulmonary Vein Size are Increased in Patients with Atrial Fibrillation Compared to Healthy Controls - A Multidetector Computed Tomography Study

“…Location 12 covers anatomically the left lateral ridge; a well-known structural complex region often re-ablated [24]. In general LAWT for controls in this study was thinner compared to previous studies [3,14,26]. Yet the control cohorts are characterized by much diversity and size variability.…”

Incidence of Atrial Fibrillation following Alcohol Septal Ablation for Hypertrophic Cardiomyopathy

“…More recently, LA percent ejection fraction has been shown to reliably identify patients with HCM at risk for development of AF . Yet others found that the LA wall in HCM patients with AF was not thicker than that of matched patients without structural heart disease, suggesting that overt atrial fibrosis and hypertrophy do not contribute to the incidence of AF …”
