A technique for bicuspidization of the aortic valve [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 1959
Although there are a dozen or more etiologies for aortic insufficiency, the ultimate problem is similar in most cases. There is a disparity between the area of the aortic orifice and the area of valve leaflet with which this orifice must be covered during diastole.

Hemodynamic Profiles Before and After Surgery in Bicuspid Aortic Valve Disease—A Systematic Review of the Literature

Frontiers in Cardiovascular Medicine, 2021
Bicuspid aortic valve (BAV) disease presents a unique management challenge both pre- and post-operatively. 4D flow MRI offers multiple tools for the assessment of the thoracic aorta in aortic valve disease.

Bicuspid aortic valve [PDF]

Annals of Cardiothoracic Surgery, 2017
Bicuspid aortic valve (BAV) has a prevalence of 0.5–1.39% in the general population. The prevalence of BAV in aortic dissection is 3.5–11.8%. Unfortunately, the incidence of aortic dissection in BAV remains unknown. The etiology of BAV is polygenetic, where environmental factors and unknown genetic factors seem to interact to cause BAV.

Atypical Expression of Smooth Muscle Markers and Co-activators and Their Regulation in Rheumatic Aortic and Calcified Bicuspid Valves

Frontiers in Cardiovascular Medicine, 2022
ObjectiveWe have previously reported that human calcified aortic cusps have abundant expression of smooth muscle (SM) markers and co-activators. We hypothesised that cells in bicuspid aortic valve (BAV) cusps and those affected by rheumatic heart valve ...

Prevalence of Bicuspid Aortic Valve and Associated Aortopathy in Newborns in Copenhagen, Denmark.

Journal of the American Medical Association (JAMA), 2021
Importance The prevalence and characteristics of bicuspid aortic valve (BAV) are mainly reported from selected cohorts. BAV is associated with aortopathy, but it is unclear if it represents a fetal developmental defect or is secondary to abnormal valve ...

Three-year outcomes of transcatheter aortic valve implantation for bicuspid versus tricuspid aortic stenosis.

EuroIntervention, 2022
BACKGROUND Transcatheter aortic valve implantation (TAVI) might be a feasible treatment option for more patients with bicuspid aortic valve (BAV) stenosis. However, long-term follow-up data in this population are scarce.

Effectiveness of Two Techniques in Removal of Calcium Hydroxide Medicament from Root Canals: An in-vitro Assessment [PDF]

Journal of Clinical and Diagnostic Research, 2018
Introduction: Calcium Hydroxide {Ca(OH)2 } is widely used as intracanal medicament. However, complete removal of Ca(OH)2 is very difficult from canal walls resulting in its residues on canal wall which interfere with bonding of sealers and reduce success

Elucidation of the genetic causes of bicuspid aortic valve disease

Cardiovascular Research, 2022
Aims The present study aims to characterize the genetic risk architecture of bicuspid aortic valve (BAV) disease, the most common congenital heart defect.

Contribution of NOTCH1 genetic variants to bicuspid aortic valve and other congenital lesions

Heart, 2022
Introduction Bicuspid aortic valve (BAV) affects 1% of the general population. NOTCH1 was the first gene associated with BAV. The proportion of familial and sporadic BAV disease attributed to NOTCH1 mutations has not been estimated.

Geometric characteristics of bicuspid aortic valvesCentral MessagePerspective

JTCVS Techniques, 2021
Objective: We studied the coaptation angles α and β in bicuspid aortic valve geometry from computed tomography scan images. Methods: In 45 patients, we calculated the coaptation angle α (the angle between the nonfused commissures crossing the center of ...
