Low normal LV function with a mitral ring prosthesis

This patient has relatively preserved LV function but appears to have a mitral repair prosthesis.

Status post transplant, Shumway procedure

This parasternal long axis TTE clip shows a patient with a bulge in the mid-wall of his left atrium. He recently underwent a Shumway procedure orthotopic heart transplant in which part of the recipient\s atrium is retained.

Severe Aortic valve stenosis and calcification

This parasternal short axis TTE clip of the aortic valve demonstrates that shi valve is severely calcified and appears very stenotic. Doppler estimated pressure gradient across this valve was between 60 and 80 mm Hg at peak.

Bioprosthetic Aortic Valve

This transthoracic TTE clip shows a patient with a bioprosthetic aortic valve. The doppler study was limited but it did not appear to have any significnat stenosis or regurgitation.

Diseased bicuspid Aortic valve

This short axis view of the aortic valve demonstrates severe stenosis and it appears to be bicuspid. Valve area measured by the continuity equation was estimated at 0.69 cm2.

Moderate to Severe Aortic Stenosis

Parasternal short axis view of a patient with mdoerate to severe aortic stenosis with valve area calculated to be 0.76 cm2. This is a side by side of loops with and without color flow doppler. Note the poor excursion of the valve leaflets and the turbulent flow on CFD (loop on right)
