Endoscopic Mitral Surgery in Noonan Syndrome-Case Report and Considerations.
J Clin Med
January 2025
Department of Surgery IV, George Emil Palade University of Medicine, Pharmacy, Science and Technology of Targu Mures, 38 Gheorghe Marinescu Street, 540139 Targu Mures, Romania.
: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.

Background: Focal pulsed-field ablation (F-PFA) integrated in electroanatomical mapping (EAM) systems allows tailored lesion sets in patients with atrial fibrillation (AF).
Objective: To determine feasibility, safety and 6-months outcome of F-PFA for a tailored substrate-based catheter ablation (CA) approach in patients with AF and advanced atrial substrate.
Methods: Consecutive patients with AF and advanced atrial substrate treated by a F-PFA system (Cardiofocus) through contact-force sensing catheters integrated in EAM systems were prospectively enrolled.
Peak Frequency Analysis and Functional Substrate Mapping to Predict Critical Isthmus of Atypical Atrial Tachycardia; Findings from a Novel Automated Annotation Algorithm to Detect Near Field Signals.
Heart Rhythm
January 2025
Hacettepe University, Faculty of Medicine, Department of Cardiology, Ankara, Turkey.
Background: Atypical atrial tachycardia (AT) is a commonly encountered rhythm disorder especially in patients with underlying atrial scar. Peak frequency (PF) annotation of bipolar electrograms is a novel method, which mainly aims to discriminate near-field and far-field signals.
Objective: To evaluate the association between PF annotation of low-voltage zones (LVZ) and deceleration zones (DZ) during sinus / paced rhythm and their role to predict the critical isthmus (CI) and termination sites of atypical ATs.
Left Atrial Papillary Fibroelastoma Mimicking Myxoma.
JACC Case Rep
January 2025
Department of Cardiovascular Medicine, Mayo Clinic, Rochester, Minnesota, USA.
Papillary fibroelastomas (PFEs) followed by cardiac myxomas (CM) are the 2 most common primary benign cardiac tumors. Although typically asymptomatic, they can manifest with nonspecific symptoms such as dyspnea and dizziness or more acute manifestations such as embolic events. We describe an unusual location of a PFE typically seen with a CM.

Division of Cardiology, Geneva University Hospitals, Geneva, Switzerland.
Atrial flutter (AFL), defined as macro-re-entrant atrial tachycardia, is associated with debilitating symptoms, stroke, heart failure, and increased mortality. AFL is classified into typical, or cavotricuspid isthmus (CTI)-dependent, and atypical, or non-CTI-dependent. Atypical AFL is a heterogenous group of re-entrant atrial tachycardias that most commonly occur in patients with prior heart surgery or catheter ablation.
