Transcript of the video: Closure line of aorticvalve on M-Mode echocardiogram, is seen as central line, while in bicuspid aorticvalve, it is an eccentric closure, nearer to one of the walls of the aorta. That is an important feature of bicuspid aorticvalve on M-Mode echocardiogram. This is a closure line.
Transcatheter aorticvalve replacement (TAVR) is increasing in popularity for symptomatic severe aorticstenosis. Transfemoral arterial route is the most commonly used approach for TAVR, also known as TAVI or transcatheter aorticvalve implantation. No calcifications in the artery causing vascular stenosis.
Mitral valve leaflets seen in open position between the left ventricle and left atrium are thickened. 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 aorticvalve can be seen between the aorta and left ventricle.
SMART 4 ( NCT04722250 ) studied patients with severe aorticstenosis and a small aortic annulus who underwent transcatheter aorticvalve replacement (TAVR). A total of 716 patients underwent TAVR with either a self-expanding supraannular valve or a balloon-expandable valve. vs. 6.2%) and stroke (2.9%
It is shown as a circle along the dotted Doppler line in the image, just beyond the aorticvalve. Most of the abnormal jets across abnormal valves and those across a ventricular septal defect and patent ductus arteriosus need either continuous wave or high pulse repetition Doppler for analysis due to the high velocity.
Usual structures imaged in this view are the right ventricular free wall and outflow region, interventricular septum, aorta, and aorticvalve, left ventricular outflow tract, anterior and posterior mitral leaflets, left ventricular cavity, posterior wall of left ventricle and left atrium.
