External aortic annuloplasty with a dedicated expansible ring improves outcomes in remodeling root repair compared to homemade Dacron ring.
In remodeling valve-sparing root replacement with external annuloplasty, we compare long-term outcomes of a calibrated expansible extra-aortic ring with a homemade Dacron ring. ⋯ Valve-sparing root remodeling with calibrated expansible extra-aortic ring annuloplasty improves the outcomes of reoperation and recurrent AI compared with a homemade Dacron ring. It prevents dilation and maintains physiological root dynamics for durable valve repair.

Efficacy of a surgical cardiac ablation clamp using nanosecond pulsed electric fields: An acute porcine model.
To examine the effectiveness of a recently developed nonthermal technology, nanosecond pulse-field ablation (nsPFA), for surgical ablation of the atria in a beating heart porcine model. ⋯ The novel nsPFA clamp device was effective in creating acute conduction block and transmural lesions in both the right and left atria in an acute porcine model. This nonthermal energy source has great potential to both shorten procedural time and enable effective ablation in the beating heart.

Outcomes of extracardiac Fontan operation: A single institution experience with 398 patients.
The study objective was to evaluate the outcomes of the extracardiac Fontan operation at a single institution. ⋯ Rates of failure of the Fontan circulation are low after the contemporary extracardiac Fontan operation. Risk factors for failure of the extracardiac Fontan circulation include right ventricular dominance, aortic atresia, and elevated pulmonary artery pressures.
