Quadricuspid aortic valve: intraoperative echocardiographic approach [PDF]
, 2021 La válvula aórtica cuadricúspide se considera una malformación cardíaca rara, así como una etiología exótica de insuficiencia aórtica. La detección de esta anomalía cardíaca se puede realizar mediante ecocardiografía transtorácica y/o transesofágica ...

A Model of Fluid-Structure and Biochemical Interactions for Applications to Subclinical Leaflet Thrombosis [PDF]
, 2022 Subclinical leaflet thrombosis (SLT) is a potentially serious complication of aortic valve replacement with a bioprosthetic valve in which blood clots form on the replacement valve. SLT is associated with increased risk of transient ischemic attacks and strokes and can progress to clinical leaflet thrombosis. SLT following aortic valve replacement also

A Long‐Term Survivor with Tetralogy of Fallot Treated Only with the Classical Blalock‐Taussig Shunt
Case Reports in Cardiology, Volume 2018, Issue 1, 2018., 2018 The prognosis of tetralogy of Fallot (TOF) treated only with Blalock‐Taussig shunt (BTS) operation is unclear. A woman with TOF underwent classic BTS operation at 10 years of age. Despite no medication, she delivered two children and worked without apparent heart failure. At 72 years of age, she complained of dyspnea on exertion and leg edema.

Immersed boundary-finite element model of fluid-structure interaction in the aortic root [PDF]
, 2015 It has long been recognized that aortic root elasticity helps to ensure efficient aortic valve closure, but our understanding of the functional importance of the elasticity and geometry of the aortic root continues to evolve as increasingly detailed in vivo imaging data become available.

Material transport in the left ventricle with aortic valve regurgitation [PDF]
Physical Review Fluids, 3(11), 113101 (2018), 2018 This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.

Immersed boundary model of aortic heart valve dynamics with physiological driving and loading conditions [PDF]
Int J Numer Meth Biomed Eng, 28(3):317-345, 2012, 2017 The immersed boundary (IB) method is a mathematical and numerical framework for problems of fluid-structure interaction, treating the particular case in which an elastic structure is immersed in a viscous incompressible fluid. The IB approach to such problems is to describe the elasticity of the immersed structure in Lagrangian form, and to describe ...

Aortic, mitral and tricuspid valvular dysplasia in a 7‐month‐old colt
Equine Veterinary Education, Volume 36, Issue 11, Page e288-e294, November 2024.Summary A 7‐month‐old Warmblood cross colt was presented for the assessment of a laceration of the right hind pastern of 4‐days duration. At presentation, the colt was in poor body condition and had a rough, dull coat. Cardiac auscultation revealed a grade 5/6 pansystolic murmur on the left side and grade 4/6 continuous murmur on the left and right ...
