Abstract

The prevalence and predictors of atrial tachyarrhythmias (ATa) in patients with pulmonary hypertension (PH) is less well understood. We performed a retrospective study including 311 patients with PH, confirmed by right heart catheterization in our center between 2007 and 2011. Baseline characteristics, clinical, echocardiographic, and hemodynamic data were collected and compared between patients with and without ATa. The mean age was 61 ± 13 years with 64 % females. The mean pulmonary artery pressure (mPAP) was 46 ± 20 mmHg, mean left ventricular ejection fraction (LVEF) was 55 ± 13 %, and mean pulmonary capillary wedge pressure (PCWP) was 19 ± 9 mmHg. Of the 311 patients with PH, 121 (39 %) patients had ATa. Patients with ATa were older (p

Abstract

An association between atrial fibrillation (AF) and gastroesophageal reflux disease (GERD) and/or irritable bowel syndrome (IBS) is increasingly being identified; yet the role of radiofrequency catheter ablation (RFA) of AF has not been systematically evaluated in these patient populations.We performed a prospective matched case-control study of AF patients with GERD and/or IBS who underwent RFA for AF in two centers in North America. AF patients with GERD and/or IBS (gastrointestinal [GI] group) were matched by age, gender, and type of AF at each of the centers with an equal number of AF patients without GERD or IBS (non-GI group).Sixty patients were included in the study with 30 in each group. Mean age of the population was 45 years with 14 (47 %) males and 21 (87 %) patients with paroxysmal AF in each group. More patients in the GI group had identifiable GI triggers for AF episodes. During RFA, more patients in the GI group had a "vagal response" compared to non-GI group (60 vs 13 %; p 0.001). Left atrial scar as identified by electroanatomical mapping was more common in patients in the non-GI group compared to the GI group (57 vs 27 %; p = 0.018). At 1-year follow-up, 56 (93 %) of the patients were free from AF with no difference between both groups.Majority of AF patients with GERD and/or IBS have triggered AF and a positive vagal response during RFA. RFA is equally effective in this patient population when compared to those without GERD or IBS.
