Cardiac effects of CPAP treatment in patients with obstructive sleep apnea and atrial fibrillation.
Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for the development and progression of atrial fibrillation (AF). We aimed to investigate the changes in heart rate and atrial and ventricular ectopy after continuous positive airway pressure (CPAP) treatment in patients with OSA and AF. ⋯ There is a significant decrease in atrial and ventricular ectopy count/24 h in patients with AF and OSA at 3 and 6 months of CPAP treatment compared to baseline.

Observational StudyThe relationship between obstructive sleep apnea and recurrence of atrial fibrillation after pulmonary vein isolation using a contact force-sensing catheter.
Our aim was to elucidate the relationship between obstructive sleep apnea (OSA) and atrial fibrillation (AF) recurrence after repeated pulmonary vein isolation (PVI). ⋯ The rate of AF recurrence might not be greater in patients with untreated OSA than in those without OSA and those with treated OSA after repeated PVI, using a contact force-sensing catheter, for patients with paroxysmal or short-term persistent AF.

Left atrial appendage exclusion during mitral valve surgery and stroke in atrial fibrillation.
The purpose of this study was to determine whether surgical left atrial appendage (LAA) exclusion performed during mitral valve surgery is associated with a reduction in cerebrovascular events in patients with atrial fibrillation. ⋯ LAA exclusion was associated with fewer cerebrovascular events. However, this benefit was seen only with concomitant surgical ablation.

Comparative StudyAtrial resynchronization therapy in patients with atrial fibrillation and heart failure with and without systolic left ventricular dysfunction: a pilot study.
We examined the long-term (≥ 5 years) outcomes of dual-site atrial pacing (DAP) when added to background antiarrhythmic drugs (AADs) and/or ablation in patients with refractory atrial fibrillation (AF) and heart failure (HF). ⋯ ART using DAP as add on therapy improved HF and established long-term RC in many patients with HFrEF and HFpEF with refractory AF. Long-term survival rates were superior in HFpEF than HFrEF.

Multicenter Study Comparative StudyElectrophysiological characteristics and radiofrequency ablation of sustained monomorphic ventricular tachycardia in adult patients with isolated ventricular noncompaction.
This study examined electrophysiological characteristics and outcomes of patients with sustained ventricular tachycardia (VT) in the setting of isolated ventricular noncompaction (IVNC). ⋯ IVNC Patients with sustained VTs appear to have a poor prognosis despite receiving ICD or apparently successful VT ablation therapy. Further, most VTs appear to arise remote from the noncompaction zone. Whether these VTs were "idiopathic" or related to IVNC was uncertain.
