Anatomic, histopathologic, and echocardiographic features in a dog with an atypical pulmonary valve stenosis with a fibrous band of tissue and a patent ductus arteriosus

Acta Veterinaria Scandinavica, 2017
Background Congenital pulmonary valve stenosis and patent ductus arteriosus are common congenital heart defects in dogs. However, concurrence of atypical pulmonary valve stenosis and patent ductus arteriosus is uncommon.

Echocardiogram of the Pulmonary Valve

Japanese Heart Journal, 1974
The echogram of the pulmonary valve was recorded in 11 normal subjects and in 70 patients with various underlying disease. On the routine examination, the detection of the pulmonary valve was about 20%, but the aimed study disclosed the valve more frequently. The technique was described in detail.

A geometric model for the human pulmonary valve in its fully open case. [PDF]

PLoS ONE, 2018
The human pulmonary valve, one of the key cardiac structures, plays an important role in circulatory system. However, there are few mathematical models to accurately simulate it. In this paper, we establish a geometric model of the normal human pulmonary

Quadricuspid Pulmonary Valve

Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging, 2018
Quadricuspid pulmonary valve (QPV) is a rare congenital cardiac malformation which is notable for its asymptomatic behavior. With only a few hundred cases reported in literature, its clinical significance is not exactly known, although many authors have placed its implications on the Ross procedure. We report a case of QPV which was detected on routine

A Rare Cardiac Anomaly in Absent Pulmonary Valve Syndrome with Tetralogy of Fallot [PDF]

, 2018
Heart failure and cardiomegaly are observed in patients with absent pulmonary valve syndrome with tetralogy of Fallot (TOF), unlike in those with TOF alone. Additional cardiac anomalies can also be seen in these patients, although not frequently.

Spectrum of pulmonary valve morphology and its relationship to pulmonary trunk in tetralogy of Fallot

Indian Journal of Radiology and Imaging, 2017
Background: Tetralogy of Fallot (TOF) is a complex congenital heart disease with anatomic variations. Although the pulmonary valve in TOF is abnormal, it has not been studied well, especially on newer imaging modalities such as multidetector computed ...

Impact of right ventriculotomy for tetralogy of Fallot repair with a pulmonary valve–sparing procedureCentral MessagePerspective

JTCVS Open, 2022
Objectives: The study objectives were to reconfirm the superiority of the pulmonary valve-sparing procedure versus the transannular patch procedure for repair of tetralogy of Fallot and to evaluate the influence of a right ventriculotomy in the pulmonary

Handmade Trileaflet Valve Design and Validation for Pulmonary Valved Conduit Reconstruction Using Taguchi Method and Cascade Correlation Machine Learning Model

IEEE Access, 2018
Pulmonary valve diseases in children and adults include different degrees of stenosis, regurgitation, or congenital defects. Valve repair or replacement surgery is used to treat valvular dysfunction and to improve regurgitations flow for pulmonary valve ...
