The mature heart valves are dynamic structures composed of highly organized cell lineages and extracellular matrices. The discrete architecture of connective tissue within valve leaflets and supporting structures allows the valve to withstand life-long functional demands and changes in hemodynamic forces and load. The dysregulation of ECM organization is a common feature of heart valve disease and can often be linked to genetic defects in matrix protein structure or developmental regulation. Recent studies have identified specific regulatory pathways that are active in the developing valve structures and also control cartilage, tendon, and bone development. This review will focus on the regulatory hierarchies that control normal and abnormal heart valve development in parallel with other connective tissue cell types.

Aims: This study compared echocardiography (echo) and cardiac computed tomography (CT) in measuring the Wilkins score and evaluated the potential added benefit of CT in predicting immediate percutaneous mitral valvuloplasty (PMV) outcomes in rheumatic mitral stenosis (MS) patients deemed eligible for PMV by echo.
Methods And Results: From a multicentre registry of 3,140 patients with at least moderate MS, we included 96 patients (age 56.4±11.

The pulmonary valve (PV), although often less emphasized than other heart valves, is crucial for cardiac function and hemodynamics. Historically, the PV has been underrepresented in echocardiographic assessments due to its rare involvement in pathological conditions, particularly in adults. Additionally, the anatomical position of the PV makes it one of the most challenging valves to visualize using conventional echocardiography.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Background: Transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with severe aortic valve stenosis; however, clinical valve thrombosis is a major challenge.
Case Summary: A 92-year-old woman underwent TAVR for severe aortic stenosis. One month later, the patient developed acute heart failure.

We report a 75-year-old female with a history of two heart operations: aortic valve replacement (St. Jude Medical 21 mm) at the age of 44 years for severe rheumatic aortic stenosis and mitral valve replacement (Carbomedics 29 mm) at the age of 51 years for rheumatic mitral regurgitation. Decades later, she presented with exertional dyspnea.
