Conversion to Cardiac Surgery During Elective and Urgent Transcatheter Aortic Valve Implantation: A Systematic Review and Meta‐Analysis

Catheterization and Cardiovascular Interventions, Volume 107, Issue 1, Page 210-220, January 1, 2026.
ABSTRACT Transcatheter aortic valve implantation (TAVI) has become an established treatment for severe aortic stenosis. However, the need for unplanned conversion to cardiac surgery (CS) during TAVI remains an infrequent but critical event. It is unclear whether this risk is higher in patients undergoing urgent procedures.

Percutaneous Management of Right Ventricular Outflow Tract Obstruction in an Adult Patient After Atrial Switch: A Case for Targeted Infundibular Ablation

Catheterization and Cardiovascular Interventions, Volume 107, Issue 1, Page 357-360, January 1, 2026.
ABSTRACT Alcohol septal ablation is a well‐established treatment method for patients with hypertrophic cardiomyopathy. We present a case report of a patient with transposition of the great arteries (TGA) after a Mustard procedure, who developed significant right ventricular outflow tract obstruction (RVOTO), functionally resembling subaortic stenosis ...

Isolated Right Ventricular Hypertrophic Cardiomyopathy Mimicking an Intramural Mass in a 13‐Year‐Old Male

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Hypertrophic cardiomyopathy (HCM) primarily involves the left ventricle, with severe right ventricular hypertrophy or right ventricular outflow tract (RVOT) obstruction being rare. Hypertrophic myocardium may mimic intramural masses, requiring imaging, intraoperative observation and pathological examination for diagnosis.

Integrative Evidence From Metabolome‐Wide Mendelian Randomization and Animal Models Implicates Tyrosine in Cardiac Hypercontractility and Arrhythmia Risk

Food Frontiers, Volume 7, Issue 1, January 2026.
Plasma metabolome‐wide Mendelian randomization analysis established a causal link between tyrosine and arrhythmia. GWAS meta‐analysis identified tyrosine‐associated loci linked to cardiovascular risk factors. Animal studies confirmed that oral tyrosine intake modulates heart rhythm via adrenergic signaling activation.

Ultrasound‐Based Z Score and Pulmonary Valve/Aortic Valve Diameter Ratio Improving the Predictive Value of Fetal Aortic Stenosis

Journal of Clinical Ultrasound, Volume 54, Issue 1, Page 64-72, January 2026.
A total of 24 singleton fetuses with suspected AS who underwent two or more fetal echocardiograms were enrolled in this study. Using electronic spatiotemporal image correlation (eSTIC) technology, the AV and PV Z scores, along with the PV/AV ratio, were measured and compared between two echocardiographic examinations to assess diagnostic efficacy ...
