Transcatheter Mitral‐Valve Repair in Patients with Heart Failure
New England Journal of Medicine, 2018 BACKGROUND Among patients with heart failure who have mitral regurgitation due to left ventricular dysfunction, the prognosis is poor. Transcatheter mitral‐valve repair may improve their clinical outcomes.

Transcatheter Edge-to-edge Repair of Severe Tricuspid Regurgitation
US Cardiology Review, 2019 Despite the increasing knowledge of the long-term adverse consequence of severe tricuspid regurgitation (TR), most patients with moderate- to-severe TR are still treated conservatively because of the high risk of surgery.

The living aortic valve: From molecules to function. [PDF]
, 2014 The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

Controlled Comparison of Simulated Hemodynamics across Tricuspid and Bicuspid Aortic Valves [PDF]
, 2021 Bicuspid aortic valve is the most common congenital heart defect, affecting 1-2% of the global population. Patients with bicuspid valves frequently develop dilation and aneurysms of the ascending aorta. Both hemodynamic and genetic factors are believed to contribute to dilation, yet the precise mechanism underlying this progression remains under debate.
