Clinical Context and Mechanism of Functional Tricuspid Regurgitation in Patients With and Without Pulmonary Hypertension

.

Conclusions—Idiopatic-TR is frequent, linked to aging and atrial fibrillation, can be severe, and is of unique mechanism. In Id-TR, excess annular and RV-basal enlargement exhausts valvular/annular coverage reserve, and RV conical deformation does not cause notable valvular tenting. Conversely, Hypertension-TR is determined by valvular tethering with tenting linked to RV elongation and elliptical/spherical deformation. These specific FTR-mechanisms may be important in considering surgical correction in FTR.

Interessante abordagem da regurgitação tricúspide com valva normal anatomicamente e funcionalmente doente por mecanismos diferenciados.

Notem que o formato do ventrículo direito é fundamental para o tipo de refluxo.
