A 25-year follow-up study found that increasing mitral regurgitation severity was associated with higher mortality risk, while surgery was linked to improved survival.

A matched cohort study found no significant differences in tricuspid regurgitation progression between left bundle branch area pacing and conventional cardiac resynchronisation therapy.

Comprehensive echocardiographic guidance was shown to support all stages of transcatheter tricuspid valve interventions, from patient selection and device deployment to postprocedural assessment and complication monitoring.

New evidence suggests bipolar radiofrequency ablation remains the preferred strategy for difficult ventricular tachycardia, while pulsed field ablation requires further validation.

An iatrogenic atrial septal defect reduced pulmonary capillary wedge pressure in computational and swine models of acute myocardial infarction without immediate haemodynamic instability.

A UK consensus statement has been developed by 26 expert interventional cardiologists recommending broader intravascular ultrasound use during percutaneous coronary intervention.
