Prosthetic TTK Chitra aortic valve on chest X-ray

X-ray chest PA view showing a prosthetic aortic valve within the lower portion of the cardiac silhouette overlapping the spine. Multiple sternal suture wires are also seen on this chest X-ray. There is mild obliteration of costophrenic angles suggesting minimal pleural effusion. Only the cobalt based alloy cage of the prosthetic valve is seen on this chest X-ray. It is a tilting disc valve with non radio-opaque disc made of polyethylene. Hence the disc cannot be seen on the X-ray image. Left dome of diaphragm is slightly elevated compared to the right, though normally the right dome is at a higher level than the left.

This X-Ray image is that of a TTK Chitra heart valve. Several studies have been published on the use of this valve [1,2,3]. Ten year outcomes have been published by Muralidharan S and colleagues in 2011 [4].
