New pathological illuminations on 3D transillumination transesophageal echocardiography imaging

The use of 3D technology has significantly improved the diagnostic accuracy of echocardiography by overcoming the limitation of 2D echocardiography. Transillumination 3D image post processing technique enhances shadows and contrast of cardiac structures with a movable virtual light source improving further the clarity and detail provided by conventional 3D imaging. In this report, we present 3 cases, one of mobile atherosclerotic aortic root plaque, another of small thrombi on ICD lead, and a third case of bicuspid aortic valve perforation due to infective endocarditis in whom TEE 3D transillumination further improved the diagnostic quality of conventional 3D imaging and lead to accurate clinical diagnosis.

Evaluation of subvalvular pannus formation in mechanical aortic valve by transesophageal echocardiography

Subvalvular pannus formation is a rare but clinically important complication with prosthetic valves. Transthoracic echocardiography still plays a role in the initial assessment of mechanical aortic valve dysfunction. But evaluation with transesophageal echocardiography is more useful. Subvalvular area may be a blind spot of echocardiography due to acoustic shadowing. The case presented herein underlines the significant role of transgastric plane and three-dimensional TEE in the assessment of subvalvular pannus formation in mechanical aortic valves.

Successful thrombolysis of a subacute prosthetic valve thrombosis with modified ultra-slow thrombolytic therapy

Prosthetic valve thrombosis is a serious complication of heart valve surgery. According to the recent studies, thrombolytic therapy is an important alternative therapy to the open heart surgery with successful outcomes. We present a case of a prosthetic mitral valve thrombosis who was successfully treated with modified ultra-slow thrombolytic therapy.
