A. A. Introduction. Multidetector computed tomography (MDCT) is a useful adjunct imaging modality in the assessment of native and prosthetic heart valve-related complications. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) remain the primary noninvasive modalities for valvular assessment, but MDCT can be useful

Echocardiography is the key noninvasive modality for evaluation of prosthetic valve structure and function [ 1 ]. Transthoracic echocardiography (TTE) is the mainstay for monitoring prosthetic valves and can generally identify normal function as well as evidence of valve dysfunction (stenosis). Transesophageal echocardiography (TEE) is helpful

CT provides a 3D data set that allows good to excellent visualization of anatomic details of the mitral valve and its apparatus including thickening of the mitral valve leaflets, annular, and leaflet calcification and has good agreement with echocardiography and surgery in diagnosing mitral valve abnormalities. 53 It can be used to reliably

Prosthetic valve endocarditis. Prosthetic valve endocarditis is a potentially fatal condition with a 20-34% mortality rate. 13 Prompt diagnosis is therefore vital to prevent severe morbidity and death. Cardiac CT can accurately identify large vegetations and paraprosthesis abscess or pseudoaneurysm formation.

Abstract. Cardiac computed tomographic angiography (CTA) using multidetector computed tomographic scanners has proven to be a reliable technique to image the coronary vessels. CTA also provides excellent visualization of the mitral and aortic valves, and yields useful information regarding valve anatomy and function.

3. "How to" Evaluate Cardiac Valves by CT. Multiplanar reformations (MPR) on advanced 3-D post-processing workstations or thin client server based solutions are mandatory for aortic valve assessment. The aortic valve should be reviewed on thin slices MPR (1 mm slice width) and reconstructed in three different views (Figure 2) (left sagittal oblique, left coronal oblique, and cross

Abstract. Rapid advancements in transcatheter mitral valve procedures have driven an increasing demand on noninvasive imaging to help assist in evaluation and procedural planning, with echocardiography and CT playing complementary roles in preprocedural work-up. The role of noninvasive imaging to help guide transcatheter aortic valvular

The annual rate of mechanical valve thrombosis has been estimated between 0.1% and 5.7%. Because of slower blood flow, thrombosis rates are higher for valves in the mitral versus aortic position and higher for right- compared to left-sided valves; implantation of right-sided mechanical valves is rare [].Most valve thrombosis occurs within months or a year after implantation, and is more common

Although echocardiography remains the principal imaging technique for assessment of the cardiac valves, contrast material-enhanced electrocardiographically gated computed tomographic (CT) angiography is proving to be an increasingly valuable complementary modality in this setting. CT angiography allows excellent visualization of the morphologic features and function of the normal valves, as

Transcatheter mitral valve replacement (TMVR) is a catheter-based interventional technique for treating mitral valve disease in patients who are at high risk for open mitral valve surgery and with unfavorable anatomy for minimally invasive edge-to-edge transcatheter mitral valve repair. There are several TMVR devices with different anchoring mechanisms, delivered by either transapical or

Recent studies have demonstrated that cardiac CT and MRI are important adjuncts to echocardiography for the evaluation of aortic and mitral valvular heart diseases (VHDs). Radiologists should be aware of the technical aspects of cardiac CT and MRI that allow comprehensive assessment of aortic and mitral VHDs, as well as the typical imaging

A pressure half-time ˃130 msec is the single best indicator of prosthetic obstruction. 2. Taking into account heart rate is not necessary when assessing trans-mitral gradients. 3. Pannus in-growth is more common in the mitral position than with aortic PHVs. 4. A peak velocity ≥2.5 m/sec suggests significant stenosis.

Computed tomography (CT) and magnetic resonance (MR) imaging are increasingly important adjuncts to echocardiography for the evaluation of mitral valve disease. The mitral valve may be involved in various acquired or congenital conditions with resultant regurgitation or stenosis, and many of these conditions can be identified with CT or MR imaging. In addition, CT is useful for detecting and
