Eccentricity Index in Bicuspid Aortic Valve

All About Cardiovascular System and Disorders

Transcript of the video: Closure line of aortic valve on M-Mode echocardiogram, is seen as central line, while in bicuspid aortic valve, it is an eccentric closure, nearer to one of the walls of the aorta. This eccentricity of closure of the aortic valve leaflets, can be calculated using what is known as eccentricity index.

Brachiocephalic Artery Access for Transcatheter Aortic Valve Replacement

All About Cardiovascular System and Disorders

Transcatheter aortic valve replacement (TAVR) is increasing in popularity for symptomatic severe aortic stenosis. Transfemoral arterial route is the most commonly used approach for TAVR, also known as TAVI or transcatheter aortic valve implantation. No calcifications in the artery causing vascular stenosis.

Fetal aortic valvuloplasty

All About Cardiovascular System and Disorders

Fetal aortic valvuloplasty is considered for fetuses with severe valvar aortic stenosis and echocardiographic features suggesting a risk of progression to hypoplastic left heart syndrome. So if progression to hypoplastic left heart syndrome can be prevented by fetal aortic valvuloplasty, that would be theoretically a great boon.

Echocardiographic evaluation in aortic regurgitation

All About Cardiovascular System and Disorders

The large aortic regurgitation jet can be seen as a mosaic jet in the left ventricular outflow tract anterior to the anterior mitral leaflet. A portion of the thickened aortic valve can be seen between the aorta and left ventricle. Thickening of both aortic and mitral leaflets indicate the possible etiology as rheumatic.

Surgical Treatment of Tetralogy of Fallot and Sequelae

All About Cardiovascular System and Disorders

One is ventricular septal defect, second is overriding aorta, third is pulmonary stenosis, usually right ventricular outflow tract stenosis and associated right ventricular hypertrophy. You can see the ventricular septal defect and aortic over ride. Pulmonary stenosis, which is usually right ventricular outflow tract stenosis.

Fractional flow reserve for guiding coronary intervention and functional SYNTAX score

All About Cardiovascular System and Disorders

Coronary angiography gives a visual impression about the severity of the stenosis. But it need not imply the actual functional significance of the stenosis in terms of flow physiology. A downside of the study was that it had included lesions of 50 to 79% stenosis also. identified physiologically significant stenosis.

Arterial Switch Operation

All About Cardiovascular System and Disorders

Graft material has the disadvantage that it will not grow as the baby grows and can lead to supravalvar pulmonary stenosis later, one of the delayed complications of arterial switch. This is diagrammatic representation of stenosis of pulmonary artery at the site where it has been repaired.
