Congenital subaortic stenosis by accessory mitral valve tissue, recognition and management [PDF]

open access: yes, 2017
Accessory mitral valve tissue as the single cause for left ventricular outflow tract obstruction is a very rare cardiac malformation in normally connected hearts.

Myocardial deletion of Smad4 using a novel alpha skeletal muscle actin Cre recombinase transgenic mouse causes misalignment of the cardiac outflow tract [PDF]

open access: yes, 2010
S MAD4 acts as the converging point f or T GF β and BMP signaling in heart development. Here, we investigated the role of S MAD4 in heart development usi ng a novel α skeletal muscle actin Cre recombinase (MuCre) transgenic mouse strain.

Sinus of Valsalva Aneurysm Dissecting into Interventricular Septum Compressing RVOT [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Aneurysm of sinus of valsalva is a rare disorder. Rupture of sinus of valsalva into the right atria, right ventricle and the left ventricle is more commonly seen.

A coupled mitral valve -- left ventricle model with fluid-structure interaction

open access: yes, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

open access: yes, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these

Catheter ablation of right ventricular outflow tract tachycardia using contact force guidance [PDF]

open access: yes, 2014
Outflow tract tachycardias (OTT) originating from the right or left ventricular outflow tract are thought to be benign. However, symptoms can be disabling and deterioration of left ventricular function may occur with a high arrhythmia burden.

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

open access: yes, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

Feline Hypertrophic Cardiomyopathy: A Spontaneous Large Animal Model of Human HCM. [PDF]

open access: yes, 2017
Hypertrophic cardiomyopathy (HCM) is a common disease in pet cats, affecting 10-15% of the pet cat population. The similarity to human HCM, the rapid progression of disease, and the defined and readily determined endpoints of feline HCM make it an ...
