ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

Metabolic changes during cardiac regeneration in the axolotl
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Right Ventricular Myxoma Obstructing the Right Ventricular Outflow Tract [PDF]
A12-year-old previously healthy girl developed syncope when walking at school. When she was seen in the emergency department, her heart rate was 115 bpm, the precordial impulse was active, and a thrill was palpated. Third and fourth heart sounds were heard. A grade 4/6 systolic ejection murmur was heard at the …

Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers

Exercise-Induced Intraventricular Obstruction in a Child with Near Syncope and Chest Pain During Exercise [PDF]
We report the case of a 10-year-old girl with two episodes of light-headedness and chest pain during exercise. She had an unremarkable clinical record, physical examination, ECG, and echocardiogram.

Metastasizing Leiomyoma Obstructing the Right Ventricular Outflow Tract
A very loud systolic murmur was identified during a pre-operative evaluation of a 51-year-old woman for an elective hysterectomy. The TTE showed a 4.7 cm intracardiac mass obstructing the RVOT. The patient was scheduled instead for resection of the mass.

Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.
