Background: A phrenic nerve injury (PNI) during cryoballoon (CB) pulmonary vein isolation (PVI) continues to represent a limitation of this technique. The objective of this study was to develop a novel technique with the aim of reducing the incidence of PNI.
Methods: We performed a retrospective analysis of data from two hospitals in patients with symptomatic, drug-resistant atrial fibrillation (AF) over 7 years to evaluate the incidence and clinical characteristics of PNI during cryoballoon PVI.
Article Synopsis
- The study tested whether adding allogeneic adipose tissue-derived stem cells (AASCs) to deproteinized bovine bone mineral (DBBM) would improve bone formation after sinus floor augmentation (SFA) compared to using DBBM alone.
- Eighteen minipigs were divided into three groups and euthanized at one, two, and four months post-augmentation to measure newly formed bone (NFB) and bone-to-implant contact (BIC) through histomorphometric analysis.
- Results showed no significant differences in NFB or BIC between the AASC-treated group and the control at any time point, suggesting that AASCs did not enhance bone healing compared to DBBM alone.
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).

View Article and Find Full Text PDFBackground: Takotsubo syndrome is characterized by transient regional systolic dysfunction, left ventricular (LV) dilatation, and edema, often occurring without obstructive coronary artery disease. The mechanisms underlying this stress-induced condition, especially the role of mechanical dyssynchrony in affecting systolic function, remain poorly understood.
Methods: In our study, we evaluated global LV function and mechanical dyssynchrony in 24 Takotsubo patients compared to 20 controls by analyzing pressure-volume loops and time-varying elastance.
