RT Journal Article SR Electronic T1 Severe tricuspid regurgitation 14 years after diagnosis of “transient neonatal tricuspid regurgitation” JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 88 OP 90 DO 10.1136/hrt.86.1.88 VO 86 IS 1 A1 Boshoff, D A1 Mertens, L A1 Gewillig, M YR 2001 UL http://heart.bmj.com/content/86/1/88.abstract AB A 14 year old girl presented with severe tricuspid regurgitation after she was diagnosed with “transient tricuspid regurgitation of the newborn”. In the neonatal period she had presented with severe tricuspid regurgitation without an obvious underlying anatomical cause. This spontaneously regressed during the first months of life. She was dismissed from follow up at the age of 5 years after complete normalisation of the clinical and echocardiographic examination. The subsequent evolution and management of the patient, as well as the possible pathogenesis responsible for the unusual clinical course, is discussed. This case stresses the importance of long term follow up of patients with transient tricuspid regurgitation.
