Imaging of the mechanical heart valve pannus formation with multidetector computerised tomography.
Fig. 1. Transthoracic Doppler echocardiography revealing severe obstruction of themechanical valve (A). The cause of obstruction could not be visualised by trans-oesophageal echocardiography (B). Multiplanar reformatted images on contrast-enhanced 64-slice multidetector CT clearly depict a circular mass (arrows) with high HU values involving both atrial (C) and ventricular (D) sides of mechanic...
متن کاملA mass obstructing mechanical prosthetic heart valve: thrombus or pannus?
Mahajan K, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-219573 Description Mechanical prosthetic valve obstruction carries a significant morbidity and mortality, if not treated urgently. Most notable causes of an acquired obstruction include thrombosis and pannus formation. It is critically important to exclude isolated pannus, since thrombolysis is an effective and rapid treatment option in ...
متن کاملSixty-Four-Section Cardiac Computed Tomography in Mechanical Prosthetic Heart Valve Dysfunction: Thrombus or Pannus.
BACKGROUND Distinguishing pannus and thrombus in patients with prosthetic valve dysfunction is essential for the selection of proper treatment. We have investigated the utility of 64-slice multidetector computed tomography (MDCT) in distinguishing between pannus and thrombus, the latter amenable to thrombolysis. METHODS AND RESULTS Sixty-two (23 men, mean age 44±14 years) patients with suspec...
متن کاملEarly transcatheter heart valve thrombosis detected by multidetector computed tomography
Article history: Received 7 November 2013 Accepted 18 November 2013 Available online 27 November 2013 IA–IC in the online-only Data Supplement). No paravalvular or central leakage was detected and LVEF was unaltered. Echocardiographic image quality did not allow for adequate assessment with regard to the mechanism of THV dysfunction. Contrast-enhanced multidetector computed tomography (MDCT) wa...
متن کاملEvaluation of prosthetic valve obstruction on electrocardiographically gated multidetector-row computed tomography--identification of subprosthetic pannus in the aortic position.
BACKGROUND This study was performed to evaluate the diagnostic role of electrocardiographically gated multidetector-row computed tomography (MDCT) for prosthetic valve obstruction (PVO) in the aortic position. METHODS AND RESULTS Between 2002 and 2006, 9 patients were diagnosed with PVO of an aortic bileaflet mechanical valve based on echocardiographic and cineradiographic criteria. These 9 p...
