Aims: Timely referrals for transplantation and left ventricular assist device (LVAD) play a key role in favourable outcomes in patients with advanced heart failure (HF). Cardiovascular mortality, driven by sudden cardiac death, is the main reason for dying while waiting for heart transplantation (HTx). The purpose of the Preventive Catheter Ablation for ventricular arrhythmiaS in patients with end-sTage heart faiLure rEferred for heart transplantation eValuaTion (CASTLE-VT) trial is to test the hypothesis that prophylactic catheter ablation of arrhythmogenic ventricular scar tissue will reduce mortality, need for LVAD implantation, and urgent HTx in patients with end-stage HF related to ischaemic cardiomyopathy (ICM).

This study examined three extracorporeal life support (ECLS) systems regarding mortality, bleeding complications, and intensive care unit (ICU) stay duration.
Methods: This monocentric, retrospective case-control study included all patients receiving LVAD with paracorporeal RVAD between 2009 and 2020.
Introduction: The aim of this study was to analyze the results after pediatric heart transplantation (pHTx) at our single center differentiating between ABO-incompatible (ABOi) and -compatible (ABOc) procedures.
Methods And Patients: We retrospectively analyzed outcomes of ABO-incompatible HTx procedures performed at our center and compared the data to ABO-compatible HTx of the same era. Eighteen children (<17 months) underwent pediatric HTx and seven of them underwent ABO-incompatible HTx between 2003 and 2015.
Article Synopsis
- * In a study of 194 patients, those who underwent catheter ablation showed a significant decrease in AF recurrence and improvement in their heart function, with left ventricular ejection fraction (LVEF) rising from 29.2% to 39.1% after 12 months.
- * Overall, AF ablation not only lowered AF burden but also successfully shifted patients from persistent AF to a less severe form, benefiting those with or without left atrial cardiomyopathy.
Article Synopsis
- * The study retrospectively compared outcomes of patients with coronary artery disease (CAD) and very low left ventricular function who received either CABG or LVAD, using statistical matching to analyze 168 pairs.
- * Results indicated that while LVAD patients needed longer ventilation and ICU stays, they had lower rates of postoperative renal therapy and required less temporary mechanical support; however, CABG patients had significantly better mid-term survival rates compared to those receiving LVADs.
