Spanish catheter ablation registry. 23rd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2023).

Introduction And Objectives: We report the results of the 2023 Spanish catheter ablation registry.

Methods: Procedural data were collected and incorporated into the REDCap platform by all participating centers through a specific form.

Results: There were 104 participating centers in 2023 compared with 103 in 2022.

QT interval measurement with portable device during COVID-19 outbreak.

Coronavirus Disease 2019 continues to spread and to date, no definitive treatment is available. Overcrowded and under-resourced healthcare centres have had to design different strategies to treat these patients, what includes the control of the electrocardiogram (ECG), as some drugs that have been used to treat this disease may prolong the QT interval as a side effect. During the COVID-19 outbreak, we designed a protocol for monitoring the QT interval using a portable device with Bluetooth connectivity.

Esophageal ulcers secondary to cryoenergy after pulmonary vein ablation using the second-generation balloon.

Pulmonary vein isolation is an effective treatment for patients with symptomatic paroxysmal atrial fibrillation. Cryoablation balloon therapy has been developed as an alternative. Cryoablation complications have primarily been related to phrenic nerve palsy, vascular complications, stroke, and others of lesser incidence.

Flecainide Reduces Ventricular Arrhythmias in Patients With Genotype RyR2-positive Catecholaminergic Polymorphic Ventricular Tachycardia.

Introduction And Objectives: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited disease characterized by polymorphic or bidirectional ventricular arrhythmias (VA) triggered by physical or emotional stress in young people with a structurally normal heart. Beta-blockers are the cornerstone of treatment, while flecainide has recently been incorporated into the therapeutic arsenal. The aim of this study was to report our experience with this drug.

Diagnostic accuracy of coronary ct for the quantification of the syntax score in patients with left main and/or 3-vessel coronary disease. Comparison with invasive angiography.

Background: The SYNTAX score helps in the treatment decision in multivessel coronary disease. Coronary computed tomography angiography (CTA) can measure the SYNTAX score but has been used in few patients with multivessel disease. Our aim was to assess the feasibility, accuracy and reproducibility of SYNTAX score with CCTA compared with invasive coronary angiography (ICA) in de novo left main and/or 3-vessel disease.

[Infective endocarditis in two Spanish university hospitals in different geographical locations with and without a cardiac surgery department].

Objectives: To assess possible differences in clinical presentation, microbiology, morbidity and mortality of infective endocarditis between two Spanish hospitals, one on the mainland that has cardiac surgery and one in the Canary Islands without this service.

Method: A total of 229patients consecutively diagnosed of endocarditis between 2005 and 2012, including pediatric population, were studied in the Reina Sofía Hospital (Córdoba, n=119) and Nuestra Señora de Candelaria Hospital (Tenerife, n=110). We compared the clinical, microbiological and echocardiographic data and analyzed mortality differences by binary logistic regression analysis.

Late relapse of progressive multifocal leucoencephalopathy postallogenic transplant in a young patient with CLL.

We describe a case of progressive multifocal leucoencephalopathy (PML) in a 39-year-old patient diagnosed with chronic lymphocytic leukaemia (CLL) who underwent two allogenic matched-sibling stem cell transplantations. PML was confirmed just after the first transplantation with cerebral MRI and by PCR in the cerebrospinal fluid. After immunosuppression withdrawal and cidofovir treatment, he achieved a reversal of clinical symptoms, John Cunningham (JC) virus positivity and MRI lesions regression.
