Abstract Aims The aim of this study is to explore the relationships of tricuspid annulus area (TAA) with right atrial maximal volume (RAVmax) and right ventricular end-diastolic volume (RVEDV) in healthy subjects and patients with functional tricuspid regurgitation (FTR) of different aetiologies and severities. Methods and results We enrolled 280 patients (median age 66 years, 59% women) with FTR due to left heart disease (LHD), pulmonary hypertension (PH), corrected tetralogy of Fallot (TOF), chronic atrial fibrillation (AF), and 210 healthy volunteers (45 years, 53% women). We measured TAA at mid-systole and end-diastole, tenting volume of tricuspid leaflets, RAVmax, and RVEDV by 3D echocardiography. Irrespective of TA measurement timing, TAA correlated more closely with RAVmax than with RVEDV in both controls and FTR patients. On multivariable analysis, RAVmax was the most important determinant of TAA, accounting for 41% (normals) and 56% (FTR) of TAA variance. In FTR patients, age, RVEDV, and left ventricular ejection fraction were also independently correlated with TAA. RAVmax (AUC = 0.81) and TAA (AUC = 0.78) had a greater ability than RVEDV (AUC = 0.72) to predict severe FTR (P < 0.05). Among FTR patients, those with AF had the largest RAVmax and smallest RVEDV. RAVmax and TA were significantly dilated in all FTR groups, except in TOF. PH and TOF had largest RVEDV, yet tenting volume was increased only in PH and LHD. Conclusion RA volume is a major determinant of TAA, and RA enlargement is an important mechanism of TA dilation in FTR irrespective of cardiac rhythm and RV loading conditions.

Abstract Aims  We sought to investigate tricuspid valve (TV) geometry and right heart remodelling in atrial functional tricuspid regurgitation (AF-TR) as compared with ventricular functional TR with sinus rhythm (VF-TR). Methods and results  Transoesophageal 3D echocardiography datasets of the TV and right ventricle were acquired in 51 symptomatic patients with severe TR (AF-TR, n = 23; VF-TR, n = 28). Three-dimensional right ventricular (RV) endocardial surfaces were reconstructed throughout the cardiac cycle and then postprocessed using semiautomated integration and segmentation software to calculate position of papillary muscle (PM) tips. Compared with VF-TR, AF-TR had more dilated and posteriorly displaced annulus and less leaflet tethering angles with more prominent right atrium and smaller RV end-systolic volume. On the XY (annular) plane, the centre of annulus was getting closer towards the anterior and posterior PM tips and was going away from the medial PM tip caused by prominent annular dilatation in AF-TR. On the Z-axis, the position of each PM tip in AF-TR was not so much displaced apically as that in VF-TR. Multiple linear regression analyses revealed that right atrial volume and right atrial/RV end-systolic volume ratio were determinants of annular area and orientation in AF-TR, respectively (both P < 0.001). Additionally, the posteromedial-directed component of posterior PM tip position and the apically directed component of the position of all three PM tips were independently associated with TV tethering angles of each leaflet in AF-TR (all P < 0.02). Conclusion  Right heart remodelling and its association with 3D TV geometry differ entirely between AF-TR and VF-TR, which may offer distinctive therapeutic implication.

Abstract Introduction Isolated tricuspid regurgitation (TR) prevalence is increasing in the last decades. Its presence is associated with a worse prognosis when EROA is >40 mm2. Because of high surgery risk and increasing incidence, isolated TR is a challenge in modern cardiology. Purpose To evaluate the prevalence and characteristics of isolated TR compared to other TR aetiologies in a large cohort of patients. Methods Prospective study where consecutive patients undergoing an echocardiographic study within a three-month period were included. All studies with at least moderate TR were selected. Isolated TR was defined as TR with no likely pulmonary hypertension (>50 mmHg), no overt TR cause (no intrinsic tricuspid disease, LVEF ≥50%, no pacemaker/defibrillator wire across the tricuspid, no other significant valve disease, no disease that may cause TR, no congenital or pericardial heart disease); and no previous valve surgery. Patients with isolated TR and other aetiologies were compared. Results 2121 patients with at least moderate TR were included. Isolated TR was found in 398 patients (18.8%). Basal characteristics are shown in table 1. Patients with isolated TR did not have a higher prevalence of AF (47.5% vs. 48.6% p=0.362). Isolated TR was less severe (20.5% vs. 32.1% of patients with severe TR; p<0.001) and less symptomatic (NYHA ≥ II in 27.8% of patients vs. 69.3%; p<0.001). After selecting patients with at least severe TR, patients with isolated TR were also less symptomatic (NYHA≥II in 47.8% of patients vs. 70.7%; p<0.001) and they had better RV function (TAPSE <17 mm in 13.4% vs. 35.6%; p=0.001). We found that patients with isolated severe TR had a larger tricuspid annulus diameter (25.4±0.8 mm/m2 vs. 24.0±0.3 mm/m2; p=0.047). Conclusions In this large prospective study, isolated TR is present in 18.8% of significant TR. Isolated TR was less severe, was associated with less RV dilatation (but with larger tricuspid annulus diameter) and patients had a better functional class compared to other TR aetiologies.
