Post-transseptal puncture re-entrant atrial tachycardia mimicking typical flutter.

This case report discusses the management of a 75-year-old man who developed an unusual type of atypical atrial flutter following a previous pulmonary vein isolation for paroxysmal atrial fibrillation. Despite a second attempt to re-isolate the pulmonary veins and performing cavotricuspid isthmus ablation (which was suspected to be part of the arrythmia circuit), the flutter continued and was converted to sinus rhythm through electrical cardioversion. A few weeks later, the patient's atrial tachycardia relapsed.

Shortened radiofrequency delivery time to optimize efficiency and safety of pulmonary vein isolation with the radiofrequency balloon: insights from the COLLABORATE registry.

Aims: Previous clinical studies on pulmonary vein isolation (PVI) with a radiofrequency balloon (RFB) reported safe and effective procedures using conventional ablation settings with 20/60 s RF delivery via posterior/anterior (PST/ANT) electrodes. The latest evidence suggests that reducing the application time to 15 s (s) on the posterior wall when facing the oesophageal region is as effective as applying 20 s. To prospectively assess whether reducing RF time on PST/ANT segments to 15/45 s can ensure sufficient quality of lesion metrics and compare the new shortened ablation settings with the conventional one in terms of safety, and effectiveness at 1-year.

Prophylactic ECMO Support during Elective Coronary Percutaneous Interventions in High-Risk Patients: A Single-Center Experience.

Introduction: Evidence regarding the impact of prophylactic implantation of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for elective high-risk percutaneous coronary intervention (PCI) is limited. The purpose of this paper is to evaluate the outcome during index hospitalization and 3 years after interventions.

Methods: This is an observational retrospective study including all patients undergoing elective, high-risk PCI and receiving VA-ECMO for cardiopulmonary support.

[Coxalgia].

Coxalgia is one of the most common painful complaints in orthopedic surgery. The management of a "traumatic" hip is relatively well codified, however atraumatic coxalgia is more difficult to diagnose and explore. The history and a well-conducted clinical examination are essential for the management of coxalgia.

RailTracking: A Novel Technique to Overcome Difficult Anatomy During Transradial Approach.

Objective: We aim to investigate the safety and efficacy of a new technique, "RailTracking," in the management of challenging transradial routes during percutaneous coronary interventions (PCI).

Background: The transradial access (TRA) currently represents the access site of choice in PCI, but complex anatomy could lead to complications and access-site crossover. The assisted-tracking techniques described in the past (such as balloon-assisted tracking and pigtail-assisted tracking) are based on the concept of a "guiding tapered tip" to improve trackability.

Efficacy of advanced pace-mapping technology for idiopathic premature ventricular complexes ablation.

Purpose: Catheter ablation is an effective treatment for premature ventricular complexes (PVCs). Activation mapping is accurate but requires PVCs at the time of the ablation. Pace-mapping correlation (PMC) is a supplemental tool recently developed as an integrated module for an electro-anatomical mapping platform.

Evaluation of left atrial linear ablation using contiguous and optimized radiofrequency lesions: the ALINE study.

Aims: Achieving block across linear lesions is challenging. We prospectively evaluated radiofrequency (RF) linear ablation at the roof and mitral isthmus (MI) using point-by-point contiguous and optimized RF lesions.

Methods And Results: Forty-one consecutive patients with symptomatic persistent AF underwent stepwise contact force (CF)-guided catheter ablation during ongoing AF.

Vasovagal syncope initiating ventricular fibrillation in a healthy subject.

A 62-year-old man with cured lymphoma as only significant medical history experienced a first reflex syncope after prolonged orthostatic posture, with cardiac arrest. Prolonged asystole was followed by ventricular fibrillation needing external defibrillation. The defibrillator provided complete recordings.
