ABSTRACT Atrioventricular conduction disturbances and the need for cardiac implantable electronic device (CIED) therapy are frequently required after transcatheter tricuspid valve implantation (TTVI). The interaction between the annulus, transcatheter heart valve and the leads is often complex and the optimal management under debate.

ABSTRACT Ascending thoracic aortic aneurysm formation differs fundamentally between patients with bicuspid (BAV) and tricuspid (TAV) aortic valve phenotypes, yet current clinical management largely relies on shared diameter thresholds, although clinical and scientific data fail to correlate with diameter and risk of rupture.

Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Background: The improvement rate and predictors of secondary mitral regurgitation in patients with aortic regurgitation undergoing transcatheter aortic valve replacement (TAVR) remain unclear.

Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

Valvular Heart Disease and Its Association With Death in Advanced Heart Failure
Background Valvular heart disease contributes to symptomatic heart failure, but its prevalence and prognostic significance in advanced heart failure is not well understood. Methods This retrospective population‐based cohort study included adult residents

Multiscale four‐dimensional imaging of cardiac remodelling after myocardial infarction
Abstract figure legend Multiscale 4D imaging framework for integrated phenotyping of post‐infarction remodelling. Myocardial infarction triggers dynamic changes across mechanical, haemodynamic and biological axes, progressing from acute injury and inflammation to extracellular matrix remodelling and scar maturation.
