An 83-year-old male suffering from severe symptomatic aortic valve stenosis received an implant of a biological aortic prosthesis through the femoral artery without complications. Seven days after dischargement he experienced a syncope. The patient was wearing an ECG holter monitor that day, which showed a wide QRS complex tachycardia of 300 beats per minute. The electrophysiological study revealed a bundle-branch reentry ventricular tachycardia as the cause of the syncope. Radio-frequency was applied on the right-bundle branch. Twelve months later, the patient has remained asymptomatic.
The image shows a left atrium completely occupied by a giant non-homogeneous, irregularly-surfaced mass, obstructing the disc motion, mimicking severe mitral prosthetic stenosis.
Keywords Echocardiography Á Thrombus Á Left atriumA 78-year-old man with a history of permanent atrial fibrillation and a mitral valve replacement (a 29 mm St Jude mechanical valve) for rheumatic disease 10 years before, was admitted by an acute cardioembolic coronary syndrome without ST elevation. Although he was treated with acenocoumarol his target index normalised ratio was not achieved. The transthoracic echocardiography showed that the mitral valve area measured by the pressure half time method was 0.9 cm 2 . The transvalvular gradient through the prosthesis was 10 mmHg. Because of the poor acoustic window, a transesophageal echocardiography was performed. The left atrium was completely occupied by a giant non-homogeneous, irregularly-surfaced mass (Fig. 1) which was obstructing the disc motion, mimicking severe mitral prosthetic stenosis (video 1). He was scheduled for cardiac surgery. A huge thrombus was removed but unfortunately he died during the surgery.
