Tricuspid regurgitation (TR) can occur due to many etiologies, including primary valve disease, left heart disease, annular dilatation in atrial fibrillation, or pulmonary hypertension (PH). Functional TR is caused by tricuspid annular dilatation in the setting of right ventricular remodeling. The right ventricle (RV) ischemia is an overlooked cause of functional TR which tends to diminish with an improvement in right heart functions. We present the case of a patient in whom functional TR significantly improved after percutaneous revascularization. We highlight that the ischemic RV can present with reversible functional TR or PH and emphasized the necessity of accurate detection of the etiology.
