The importance of the right ventricle as a determinant of clinical symptoms, exercise capacity, peri-operative survival and postoperative outcome has been underestimated for a long time. Right ventricular ejection fraction has been used as a measure of right ventricular function but has been found to be dependent on loading conditions, ventricular interaction as well as on myocardial structure. Altered left ventricular function in patients with valvular disease influences right ventricular performance mainly by changes in afterload but also by ventricular interaction. Right ventricular function and regional wall motion can be determined with right ventricular angiography, radionuclide ventriculography, two-dimensional echocardiography or magnetic resonance imaging. However, the complex structure of the right ventricle and its pronounced translational movements render quantification difficult. True regional wall motion analysis is, however, possible with myocardial tagging based on magnetic resonance techniques. With this technique a baso-apical shear motion of the right ventricle was observed which was enhanced in patients with aortic stenosis.

“…1 Because of a long-recognized relationship between FTR and left-sided cardiac 2,3 or pulmonary 1,4 diseases, the link FTR excessive afterload of pulmonary hypertension (PHTN) is construed as core FTR mechanism and is the main focus of guidelines for valve diseases 5 ; however, FTR remains a frustrating condition, poorly understood. 6 Epidemiological studies uncovered TR with high prevalence, even without PHTN, 7 and, conversely, severe PHTN does not necessarily cause notable FTR.…”

“…1,2 Several echocardiographic and angiographic studies have suggested important changes in the tricuspid valve (TV) geometry in patients with functional TR, including annular dilatation and tethering of the leaflets. [3][4][5] These TV deformations may restrict the motion of the leaflets and decrease coaptation.…”

Background-The durability of tricuspid valve (TV) repair by annuloplasty is limited. Identification of mechanisms of recurrent or residual tricuspid regurgitation (TR) after annuloplasty is necessary to improve results of TV repair. The purpose of this study was to investigate echocardiographic determinants of mid-term outcome after TV annuloplasty. Methods and Results-This study consisted of 39 patients with functional TR who had echocardiography preoperatively, early postoperatively (5Ϯ2 days), and Ͼ1 year (20Ϯ6 months) after TV annuloplasty. Detailed echocardiographic measurements were performed, including TR severity, TV annular dimension, TV leaflet displacement, left ventricular (LV) function, and right ventricular (RV) function and pressures. Preoperative leaflet tethering height and area predicted early and mid-term outcome of annuloplasty. Early postoperative LV ejection fraction and TR severity influenced degree of TR Ͼ1 year after surgery. In addition, increased RV pressure was related to worse TR during late follow-up. Conclusions-Although
