Multicenter Study Observational Study
Early feasibility of hypoglossal nerve upper airway stimulator in patients with cardiac implantable electronic devices and continuous positive airway pressure-intolerant severe obstructive sleep apnea.
Implantable hypoglossal nerve upper airway stimulation (HNS) is a novel strategy approved by the US Food and Drug Administration for the management of moderate-to-severe obstructive sleep apnea (OSA) in patients with continuous positive airway pressure therapy intolerance or failure. Because of the proximity of a cardiac implantable electronic device (CIED) to this stimulator, interaction between these devices is theoretically possible. ⋯ In this early experience, simultaneous use of a novel hypoglossal nerve upper airway stimulation device with transvenous CIEDs seems to be safe, effective, and without any device-device interactions.

Pulmonary vein activity does not predict the outcome of catheter ablation for persistent atrial fibrillation: A long-term multicenter prospective study.
Pulmonary vein (PV) isolation (PVI) remains the cornerstone of catheter ablation (CA) in persistent atrial fibrillation (AF) (PeAF), although less successful than for paroxysmal AF. Whether rapid or fibrillatory (PV AF) PV firing may identify patients with PeAF more likely to benefit from a PV-based ablation approach is unclear. ⋯ The rapidity of PV firing or presence of fibrillation within the PV was not predictive of outcome of CA for PeAF. PV activity does not identify patients most likely to benefit from a PV-based ablation strategy.

Pulmonary vein isolation cryoablation for patients with persistent and long-standing persistent atrial fibrillation: Clinical outcomes from the real-world multicenter observational project.
Pulmonary vein isolation (PVI) is a cornerstone ablation strategy in the management of patients with atrial fibrillation (AF). Consensus guidelines and statements recommend PVI during the index catheter ablation procedure in patients with paroxysmal and persistent AF. ⋯ In this multicenter evaluation of cryoballoon ablation, the PVI procedure was safe, effective, and efficient with regard to the treatment of patients with persistent and long-standing persistent AF. The reasonable mid-term success rates agree with current clinical studies that establish PVI as a cornerstone index ablation strategy.

Implantable cardioverter-defibrillator-computed respiratory disturbance index accurately identifies severe sleep apnea: The DASAP-HF study.
Sleep apnea (SA) is a relevant issue in the management of patients with heart failure for risk stratification and for implementing treatment strategies. ⋯ The RDI accurately identified severe SA and demonstrated good agreement with AHI. Therefore, it may serve as an efficient tool for screening patients at risk of SA.

Multicenter Study
Long-term outcomes of prophylactic placement of an endovascular balloon in the vena cava for high-risk transvenous lead extractions.
Many clinicians use the strategy of prophylactically placing an endovascular balloon before transvenous lead extraction, yet there are no data regarding this practice. ⋯ During the study period, we observed no acute or long-term adverse outcomes associated with prophylactic placement of an endovascular balloon in the venae cavae of patients undergoing transvenous lead extraction.
