Multidisciplinary Approach to Right Ventricular Myxoma [PDF]

Brazilian Journal of Cardiovascular Surgery
Right ventricular (RV) myxoma that obstructs the RV outflow tract is rare. Multimodality imaging is crucial due to the curved and triangular shape of the RV anatomy. Incomplete resection by the right atrial approach in cardiac myxomas may be prevented by

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...

Late development of double-chambered right ventricle after repair of a ventricular septal defect

Türk Kardiyoloji Derneği Arşivi, 2015
Double-chambered right ventricle is a rare heart defect causing right ventricular outflow tract (RVOT) obstruction. In this malformation, the right ventricle is divided into two chambers by a fibromuscular band.

Development and Validation of a Novel Contact Force‐Integrated Pulsed Field Quantization Index for Pulmonary Vein Isolation in a Porcine Model

Journal of Cardiovascular Electrophysiology, EarlyView.
A two‐phase pre‐clinical porcine study was performed to develop and validate the Pulsed Field Quantisation Index (PFQI), the first bipolar‐specific ablation index integrating real‐time contact force (CF), pulse‐train number, delivery voltage, and impedance variation for bipolar pulsed field ablation (PFA).

Double trouble - dual outflow tract obstruction in congenital heart disease: a case report

BMC Cardiovascular Disorders
Background Double chambered right ventricle is a rare congenital heart disease that is characterised by the presence of an anomalous muscle bundle that divides the right ventricle into a low pressure superior (distal) chamber and a high pressure inferior

A Triple Threat: A Case Report Detailing Surgical Management for Hypertrophic Cardiomyopathy, Flail Mitral Valve and Severe Pulmonary Hypertension

Reports
The combination of hypertrophic cardiomyopathy with outflow tract obstruction, severe pre-capillary and post-capillary pulmonary hypertension, and severe primary mitral regurgitation is rare and presents distinct management challenges.

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

Journal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.
