Tricuspid valve is as pointed
1.Background. Functional TR is primarily due to tricuspid annular dilation and right ventricular (RV) enlargement and dysfunction; it occurs most often secondary to left-sided heart disease, especially in the setting of mitral valve pathology.
2.Functional TR assessment. The authors propose that, in assessing functional TR, it is important to have a systematic approach that addresses its impact; which includes the severity of TR, tricuspid annular size, and the mode of tricuspid leaflet coaptation and extent of tricuspid leaflet tethering.
3.Tricuspid valve anatomy. The tricuspid valve has three leaflets (anterior, posterior, and septal). The anterior leaflet is largest in surface area and is almost always anchored by a single papillary muscle; affected most by annular dilation, functional TR occurs when annular dilation reduces coaptation of the anterior leaflet. RV enlargement can result in papillary muscle displacement, another mechanism of functional TR.
4.TR severity. TR severity is most often assessed on echocardiography using color-flow Doppler; 5.Categories of TR severity. 6.Tricuspid annular assessment
7.Leaflet coaptation. The surface of contact between the leaflets is the coaptation height
8.Tethering distance, tethering area. The distance of leaflet coaptation that forms the plane of the tricuspid annulus is the tethering distance (or tethering height
