Right heart echocardiographic variables and prediction of clinical severity in dogs with pulmonary stenosis

Journal of Veterinary Internal Medicine, Volume 37, Issue 3, Page 835-843, May/June 2023., 2023
Abstract Background Pulmonary stenosis (PS) usually is evaluated using echocardiography. A multiparametric approach, in addition to the maximum pressure gradient (PG), might be indicated to better characterize PS severity and address its management.

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.

Puérpera com trombose de prótese mecânica e estenose supravalvar aórtica adquirida Postpartum patient with thrombosis of mechanical prostheses and acquired supravalvular aortic stenosis

Brazilian Journal of Cardiovascular Surgery, 2011
A hipercoagulabilidade sanguínea proporcionada na gravidez aumenta consideravelmente a incidência de trombose de valvas mecânicas. A estenose supravalvar aórtica adquirida é extremamente rara.

Surgical treatment of Shone’s syndrome and patent ductus arteriosus in an adult

BMC Cardiovascular Disorders, 2022
Background Shone’s syndrome is a rare complex congenital anomaly. The classical definition consists of four anomalies: supravalvular mitral membrane, parachute mitral valve (PMV), subaortic stenosis, and coarctation of the aorta (CoA).

Supramitral obstruction of left ventricular inflow tract by supramitral ring [PDF]

, 2004
Supramitral ring (SMR) is a rare developmental abnormality of the supravalvular area of the mitral valve which produces a variable degree of obstruction to left ventricular filling.

Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation [PDF]

PeerJ, 4: e2240, 2016, 2016
Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics.

A rare combination of cardiovascular anomaly: Supravalvular aortic stenosis and congenital absence of right coronary artery

, 2021
We reported a case of a 3-month-old infant presented with supravalvular aortic stenosis with congenital right coronary artery deficiency. According to cardiovascular CT results, Doty technique was adopted to restore the aortic root geometry under ...

Echocardiographic Morphological Classification of Aortic Stenosis in Sulaimani Pediatric Teaching Hospital/Kurdistan/Iraq

Kurdistan Journal of Applied Research, 2017
Aortic stenosis occurs when the heart's aortic valve narrows. This narrowing prevents the valve from opening fully, which obstructs blood flow from the heart into the aorta and onward to the rest of the body.
