Bicuspid Aortic Valve Types

Bicuspid aortic valve BAV refers to a spectrum of deformed aortic valves with two functional leaflets or cusps which are often unequal in size. These characteristics served to classify and codify the bicuspid aortic valves into three categories.

Bicuspid aortic valve BCAV is one of the common congenital abnormality of heart.

Bicuspid aortic valve types. Schematic diagram and images of different bicuspid aortic valve morphology. Three major types were identified. This condition is present from birth.

The Bicuspid Aortic Valve Consortium is investigating the relationship between phenotype and genetics using a very large number 4000 of patients with well-characterised bicuspid aortic valve to allow for genome-wide association studies6 This type of research simultaneously examining the genetics and haemodynamics of bicuspid valves has. What is bicuspid aortic valve. The bicuspid aortic valve is not a disorder confined to the aortic valve but a spectrum involving the aortic valve aortic annulus aortic root ascending aorta and the left ventricular outflow tract.

These characteristics served to classify and codify the bicuspid aortic valves into three categories. Among patients with bicuspid aortic valve and raphe differentiation was possible only in systole in 5 240 of cases and when com-bining diastole and systole in 95 3840 of cases. It can result in premature aortic degeneration with Aortic stenosisAortic regurgitation or both.

Bicuspid valves are classified as type 1 right-left coronary cusp fusion type 2 right-noncoronary cusp fusion and type 3 left-noncoronary cusp fusion. Type 0 no raphe type 1 one raphe and type 2 two raphes followed by two supplementary characteristics spatial position and function. Dichotomous classification is shown in B.

They are most often congenital while an acquired bicuspid valve occurs when there is fibrous fusion between the right and left cusps of a pre-existing trileaflet aortic valve. Codify the bicuspid aortic valves into three categories. Three major types were identified.

It can occur with other heart defects. In bicuspid aortic valve the valve has only two small parts called leaflets instead of the normal three. These characteristics served to classify and codify the bicuspid aortic valves into three categories.

In three bicuspid aortic valves with raphe the valve was misclassified by CT as tricuspid aortic valve. Overall sensitivity and specificity of CT for the diagnosis of bicuspid aortic valve were 94 and 100. Type 0 no raphe type 1 one raphe and type 2 two raphes followed by two supplementary characteristics spatial position and function.

Most frequently a bicuspid aortic valve with one raphe was identified type 1 n 269. Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. The figure demonstrates BAV phenotypes.

BAV can coexist with other congenital cardiovascular malformations particularly coarctation of the aorta COA. Bicuspid aortic valve BAV is the most common congenital cardiovascular malformation affecting approximately 052 of the popu lation. The normal development and arrangement of three cusps is altered rather interrupted during fetal life.

Aortic Valveabnormalities Aortic Valvesurgery. Aortic Valve Stenosisetiology Aortic Valve Stenosissurgery. Patients with BAV are at increased risk of both valvular and vascular complications.

Three major types were identified. Incidence can be 1-2 of population. Aortic Valve Insufficiencyetiology Aortic Valve Insufficiencysurgery.

Type 0 no raphe type 1 one raphe and type 2 two raphes followed by two supplementary characteristics spatial position and function. Different types of bicuspid aortic valves may present with distinct aetiologies and morphologies. Red bands and arrows represent the raphe or commissural fusion.

The Sievers classification and echocardiographic images are shown in A.
