Correction of Tetralogy of Fallot with Absent Pulmonary Valve Syndrome in a Young Infant Using a Bicuspid Equine Pericardial Tube

Journal of the Formosan Medical Association, 2006
Absent pulmonary valve syndrome (APVS) is an uncommon variant of tetralogy of Fallot (TOF), which manifests morphologically as vestigial pulmonary valve cusps at the right ventricle-pulmonary trunk junction.

The Hammock Sign in Computed Tomography as a Detection Aid for Bicuspid Aortic Valves

Journal of the Belgian Society of Radiology, 2023
Introduction: Bicuspid aortic valve is difficult to detect on standard transverse images. Purpose: We aimed to investigate the usefulness of the hammock sign for detection of bicuspid aortic valve.

The Ross Procedure with a Bicuspid Pulmonary Autograft [PDF]

ASVIDE, 2021
BACKGROUND >We illustrate the steps for a Ross procedure in a 24-years old patient who presented with an unicuspid aortic valve with mixed aortic stenosis/aortic regurgitation and who was intraoperatively found to have a bicuspid pulmonary autograft, warranting the need for concurrent repair of the autograft.

Pulmonary artery and right ventricle function in patients with bicuspid aortic valve

Türk Kardiyoloji Derneği Arşivi, 2017
Objective: Bicuspid aortic valve (BAV) is a complex developmental anomaly caused by abnormal aortic leaflet formation during valvulogenesis. The present study is an assessment of the effects of BAV disease on the ascending aorta and pulmonary artery (PA),

Age, Sex, and Valve Phenotype Differences in Fibro‐Calcific Remodeling of Calcified Aortic Valve

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background In calcific aortic valve disease on tricuspid aortic valves (TAVs), men have higher aortic valve calcification and less fibrosis than women. However, little is known in bicuspid aortic valves (BAV).

Space closure and incisor alignment in the mandibular arch following first premolar extraction without appliance therapy

Australasian Orthodontic Journal, 1989
Changes in the mandibular arch were evaluated in 32 cases of lower first premolar extraction without appliance therapy. There was a mean reduction in the irregularity index and extraction space of 52 percent and 45 percent respectively.
