Randomized Controlled Trial
A prospective randomized controlled trial on the incidence and predictors of late-phase postoperative atrial fibrillation up to 30 days and the preventive value of biatrial pacing.
Postoperative atrial fibrillation (POAF) is considered to be a transient arrhythmia in the first week after cardiac surgery. ⋯ POAF is not limited to the first week after cardiac surgery but also occurs frequently in the postoperative month. It is desirable to regularly follow patients with POAF for atrial fibrillation recurrences after discharge.

Hemodynamic support using percutaneous left ventricular assist devices (pLVADs) during catheter mapping and ablation of unstable ventricular tachycardia (VT) can provide effective end-organ perfusion. However, its effect on procedural and clinical outcomes remains unclear. ⋯ In this nonrandomized retrospective study, catheter ablation of unstable VT supported by a pLVAD was associated with shorter ablation times and reduced hospital length of stay. While pLVAD support did not affect VT recurrence, it was associated with a lower composite end point of 30-day rehospitalization, redo-VT ablation, recurrent implantable cardioverter-defibrillator therapies, and 3-month mortality.
