P-Wave Beat-to-Beat Analysis to Predict Atrial Fibrillation Recurrence after Catheter Ablation.

The identification of patients prone to atrial fibrillation (AF) relapse after catheter ablation is essential for better patient selection and risk stratification. The current prospective cohort study aims to validate a novel P-wave index based on beat-to-beat (B2B) P-wave morphological and wavelet analysis designed to detect patients with low burden AF as a predictor of AF recurrence within a year after successful catheter ablation. From a total of 138 consecutive patients scheduled for AF ablation, 12-lead ECG and 10 min vectorcardiogram (VCG) recordings were obtained.

Trends in ablation procedures in Greece over the 2008-2018 period: Results from the Hellenic Cardiology Society Ablation Registry.

Objective: In 2008, the radiofrequency ablation (RFA) procedures registry of the Hellenic Society of Cardiology was created. This online database allowed electrophysiologists around the country to input data for all performed ablation procedures. The aim of this study is to provide a thorough report and interpretation of the data submitted to the registry between 2008 and 2018.

CPVT: Arrhythmogenesis, Therapeutic Management, and Future Perspectives. A Brief Review of the Literature.

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) is a primary electrical disease characterized by a normal resting electrocardiogram and induction of malignant arrhythmias during adrenergic stress leading to syncope or sudden cardiac death (SCD). CPVT is caused by mutations in the cardiac ryanodine receptor (RyR2) or in the sarcoplasmic reticulum protein calsequestrin 2 genes (). The RyR2 mutations are responsible for the autosomal dominant form of CPVT, while mutations are rare and account for the recessive form.

Improved 'cut-down' technique for transvenous pacemaker lead implantation.

Aims: We improved the cut-down approach aiming at minimizing the subclavian/axillary vein puncture during implantation of permanent pacemaker leads.

Methods And Results: We incorporated previously reported refinements of the cut-down approach, i.e.

Cardiac tamponade because of left atrium direct invasion by a large cell neuroendocrine metastatic carcinoma of the lung.

A 53-year-old man presented with cardiac tamponade due to direct invasion of left atrium by a large cell neuroendocrine metastatic lung adenocarcinoma. Direct invasion of left atrial cavity by this type of lung tumour is rare. When cardiac involvement is suspected, two-dimensional echocardiography is the first-line diagnostic tool.

Presentation of an embolised Amplatzer septal occluder to the main pulmonary artery 2 years after implantation.

Percutaneous occlusion techniques of secundum type atrial septal defects have recently become the treatment of choice, delivering excellent results and being associated with a low rate of early and late complications. The investigators report an unusually delayed presentation of acute right heart failure due to Amplatzer septal device embolisation into the main pulmonary artery, 2 years after implantation.

Antirestenotic effects of a novel polymer-coated d-24851 eluting stent. Experimental data in a rabbit iliac artery model.

Experimental and clinical data suggest that stents eluting antiproliferative agents can be used for the prevention of in-stent restenosis. Here we investigate in vitro the antiproliferative and apoptotic effect of D-24851 and evaluate the safety and efficacy of D-24851-eluting polymer-coated stents in a rabbit restenosis model (n = 53). Uncoated stents (n = 6), poly (DL: -lactide-co-glycolide) (PLGA)-coated stents (n = 7), and PLGA-coated stents loaded with 0.
