Abstract

Transient Tricuspid Insufficiency(TTI) of newborn is a feature of myocardial dysfunction caused by myocardial hypoxemia secondary to reduced arterial oxygen content and excessive right ventricular work consequent to pulmonary hypertension.' Since Doppler echocardiography has been used to diagnose cardiac disease, it allows recording of regurgitant turbulent flow pattern. We report one case of TTI in a 36 week-gestational-aged newborn detected by continuous wave Dopplar echocardiography with review of related literatures.
