Description
Summary:Despite the great improvements in technology over the past 4 decades, PVT has been associated with a significant death risk. [...]diagnosis and management of PVT are crucial, especially in the developing countries where this condition is prevalent.2-4 Transthoracic echocardiography is usually the first imaging modality to evaluate suspected PVT, but it is limited in evaluating valve mobility and mechanism of valvular obstruction.5,6 Transesophageal echocardiography, especially real-time (RT) handling of 3-dimensional information, has been a milestone in the era of cardiovascular imaging of both native and prosthetic valves.7-10 Real-time 3-dimensional transesophageal echocardiography provides better visualization of the atrial and ventricular sides of the prosthesis, improves understanding of the relation between cardiac structures, and helps in discriminating pannus from thrombus.11 Cinefluoroscopy is a noninvasive, readily available method for detecting PVT, especially in patients with bileaflet prosthetic valves, and plays a complementary diagnostic role in evaluating disk mobility of the prosthesis.5,12 Multislice computed tomography has also been proven to be a useful tool in the differential diagnosis of prosthetic valve dysfunction13 including PVT and pannus.
