Arrhythmias After Heart Transplantation: Mechanisms and Management

Pacemaker implantation in pediatric heart transplant recipients: Predictors, outcomes, and impact on survival

“…It is also associated with less sinus node injury and lower rates of atrial dilatation. 4,12 Although we show that donor age is a statistically significant predictor of acute PPM implantation, HR of 1.05 is small and may not be clinically meaningful. Similarly, the higher incidence of acute PPM implantation in association with biatrial anastomosis may not be clinically relevant in the current era given that most centers have moved away from this technique because of sinus node dysfunction.…”

“…3 Bradyarrhythmias in the form of atrioventricular block or sinus node dysfunction after HTx is a major complication in the posttransplant period potentially requiring permanent pacing. 4 small sample size in single-center analyses. 5,6 he incidence of bradyarrhythmias requiring pacemaker placement in the pediatric population has been variably reported at 2.8% to 6.6%.…”

The influence of surgical technique on early posttransplant atrial fibrillation — comparison of biatrial, bicaval, and total orthotopic heart transplantation

“…Prolonged ischemic time has been associated with an increased rate of posttransplant AF, especially patients with a prolonged ischemic time (≥240 minutes) are at higher risk 15. As BA-HTX has a shorter ischemic time due to fewer anastomoses, this might be associated with a decreased rate of AF.…”

Tricuspid Valve Insufficiency in Recipients With Transplanted Heart

“…Наряду с анатомическими несоответствиями использование биатриальной методики может при-водить к возникновению асинхронных сокращений сердца, что также со временем усугубляет развитие трикуспидальной недостаточности [30,31].…”
