“…Pre-procedural planning using multi-detector computed tomography (MDCT) provides many details regarding tricuspid annulus measurement, the relationship with the surrounding structures, and good-quality motion-free images of the right ventricular outflow tracts 13 . Furthermore, MDCT is used to access routes for percutaneous procedures.…”

Isolated tricuspid valve surgery is usually carried out with very high morbidity and mortality given the complexity of the affected patients. In light of this, trans-catheter tricuspid valve interventions have been emerging as an attractive alternative to surgery over the last few years. Although feasibility has been shown with a number of devices, clinical experience remains preliminary and associated with significant clinical and technical challenges. Here we describe currently available trans-catheter treatment options for severe tricuspid regurgitation implanted in different locations.

“…Successful imaging of this region necessitates homogenous enhancement around the tricuspid valve annulus, which is otherwise compromised by artifacts arising from the mixture of high-attenuation contrast from the superior vena cava and unenhanced blood from the inferior vena cava. Therefore, dilute contrast must be used for optimal visualization of right-sided cardiac structures on CT [5]. At our institution we usually use iohexol at a concentration of 350 mgI/mL for our cardiac CT studies.…”

Clinical aspects of myocardial fibrosis in adults with Ebstein’s anomaly

et al. 2018

Heart failure and arrhythmia are common complications in adults with Ebstein’s anomaly. They may result not only from hemodynamic alterations, but also from myocardial fibrosis. Late gadolinium enhancement (LGE) by CMR enables the evaluation of myocardial fibrosis. The aim of the study was to asses the presence of LGE and its relation to clinical outcome. We studied a group of 37 unoperated adults aged 43.0 ± 14.4 years with Ebstein’s anomaly from the congenital heart disease outpatient clinic. Study protocol included: cardiopulmonary test, assessment of supraventricular arrhythmia (SVA), and CMR with evaluation of cardiac chambers’ morphology and function, and presence of LGE. Variables following normal distribution were shown as mean ± SD if otherwise median (range) was applied. Fibrosis was found in 18 patients (48.6%) and was distributed as follows: 12 patients (32.4%) in the right atrium, 12 (32.4%) in the atrialized right ventricle, and 2 (5.4%) in the functional right ventricle. In patients with fibrosis, the tricuspid regurgitation fraction was bigger (48.3 ± 19.7 vs. 36.1 ± 22.6%, p = 0.048) and SVA was more frequent [12 (66.7%) vs. 6 (31.6%), p = 0.046] when compared to patients without fibrosis. However, exercise capacity did not differ between patients with and without LGE (peak VO2 24.0 ± 4.7 vs. 23.7 ± 4.4, p = 0.87). In adults with Ebstein’s anomaly fibrosis estimated by LGE-CMR was localized in the right atrium and the right ventricle only. Volume overload resulting from tricuspid regurgitation might be a factor conducive to fibrosis. Myocardial fibrosis did not influence exercise capacity. Association between myocardial fibrosis and supraventricular arrhythmia was confirmed.
