Valve-in-valve Transcatheter Aortic Valve Replacement for Failed Surgical Valves and Adjunctive Therapies

US Cardiology Review, 2022
While redo surgical aortic valve replacement has traditionally been the gold standard for the treatment of failed surgical valves, valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) has arisen as a viable, less invasive option with the ...

Outcomes in Asymptomatic Severe Aortic Stenosis With Preserved Ejection Fraction Undergoing Rest and Treadmill Stress Echocardiography

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundIn asymptomatic patients with severe aortic stenosis and preserved left ventricular ejection fraction, we sought to assess the incremental prognostic value of resting valvuloarterial impedence (Zva) and left ventricular global longitudinal ...

Quadriscupid aortic valve with concurrent aortic stenosis and insufficiency [PDF]

, 2016
We present the case of a 22-year-old man with a congenital mixed aortic valve dysfunction who underwent cardiac Magnetic Resonance Imaging (MRI) for the assessment of aortic valve morphology and function prior to valve replacement.

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.

Relationship Between the Ratio of Acceleration Time/Ejection Time and Mortality in Patients With High‐Gradient Severe Aortic Stenosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background The ratio of acceleration time/ejection time (AT/ET) is a simple and reproducible echocardiographic parameter that integrates aortic stenosis severity and its consequences on the left ventricle.
