Definitive diagnosis of infective endocarditis (IE) is mainly based on microbiological and imaging criteria. In a minority of cases, particularly when perivalvular area is involved, cardiac conduction disorders (CCD) may appear, which implies worse prognosis. In this scenario, different degrees of auriculoventricular block can occur, but development of bundle branch block is rare. Herein, we present a case of IE with negative initial imaging tests, where the occurrence of phase 4 bundle branch block after a sequence of type I second degree AV block was crucial to establish a definitive diagnosis and an optimal therapeutic approach.

Atypical Presentation of Andersen-Tawil Syndrome: Heart Failure with Reduced Ejection without Periodic Paralysis or Dysmorphic Features.
Eur J Case Rep Intern Med
December 2024
Internal Medicine, Holy Family Hospital, Rawalpindi, Pakistan.
Background: Andersen-Tawil syndrome (ATS) is a rare autosomal dominant disorder caused by variants in the gene. It is associated with periodic paralysis, dysmorphic features and cardiac arrhythmias. The syndrome exhibits incomplete penetrance, leading to a broad spectrum of clinical manifestations, making diagnosis challenging.

Background: This large-scale study analyzes factors affecting diagnostic accuracy of low-dose myocardial perfusion imaging and correlation with coronary angiography in a real-world practice.
Methods: We compared data extracted from routine reports of (i) low-dose [Tc]sestamibi stress-MPI performed with no attenuation correction and predominantly exercise stress testing and (ii) the corresponding coronary angiography.
Results: We considered 1070 pairs of coronary angiography/stress-MPI results reported by 11 physicians.
Ablate and pace strategy for atrial fibrillation: pacing modalities, ablation approaches and impact on patient outcomes.
Expert Rev Med Devices
January 2025
Cardiology Unit, "Card. G. Panico" Hospital, Tricase (Le), Italy.
Introduction: In patients with symptomatic, refractory atrial fibrillation the ablate and pace (A&P) strategy (pacemaker implantation followed by atrio-ventricular junction ablation (AVJA)) is superior to medical therapy in improving quality of life and prognosis. Despite its well-proven benefits, this invasive therapeutic option is still underutilized in clinical practice. The choice of pacing modality (right ventricular pacing, biventricular pacing, BVP, or conduction system pacing, CSP) is crucial and can have significant clinical implications.

Department of Cardiac Surgery, Klinikum Nürnberg, Paracelsus Medical University, Nuremberg, Germany.
Objectives: This study aims to investigate the association between interatrial conduction block and postoperative atrial fibrillation, which can precipitate acute cardiopulmonary instability and is associated with subsequent heart failure, stroke, and mortality following cardiac surgery.
Methods: Perioperative 12-channel electrocardiograms from 3405 patients undergoing myocardial revascularization, valve surgery, aortic surgery, or combinations thereof, were considered. Clinical and electrographic parameters were compared between patients with and without atrial fibrillation, and significant variables were analyzed using univariate and multivariate logistic regression.
Left Bundle Branch Area Pacing Versus Right Ventricular Pacing in Patients With Atrioventricular Block: A Systematic Review and Meta-Analysis.
J Cardiovasc Electrophysiol
January 2025
Division of Cardiology, Thomas Jefferson University Hospital, Philadelphia, Pennsylvania, USA.
Background: Left bundle branch area pacing (LBBAP) is a new technique for patients with atrioventricular block (AVB) and preserved left ventricular ejection fraction (LVEF), potentially offering better cardiac function than right ventricular pacing (RVP).
Methods: We searched databases and registries for studies that compared LBBAP with RVP in patients with AVB and preserved LVEF. We extracted data on various outcomes and pooled the effect estimates using random-effects models.
