Valvular Heart Disease
Published in P. Chopra, R. Ray, A. Saxena, Illustrated Textbook of Cardiovascular Pathology, 2013
Pulmonary valve insufficiency It may result from dilatation of the pulmonary artery and the valve ring secondary to pulmonary hypertension and right ventricular failure. Rarely, rheumatic valvulitis, infective endocarditis, carcinoid syndrome and congenital malformations may cause insufficiency of the pulmonary valve.

Another cause of right heart enlargement in patients without structural heart disease is DA constriction. The DA's prenatal constriction leads to increased pressure in the RV, enlargement of right heart structures, pulmonary artery enlargement, tricuspid and pulmonary valve insufficiency, and eventually, right heart failure (Gewillig et al. 2009; Alvarez and McBrien 2018). Patient # 4, both rFO and DA constriction were detected. The most likely cause of DA constriction is nonsteroidal anti-inflammatory drugs used during pregnancy (Siu and Lee 2004). It is well known that feeding the mother with polyphenol-rich foods (e.g. herbal teas, dark chocolate, orange derivatives, strawberries) increases the risk and rarely idiopathic (Trevett and Cotton 2004; Zielinsky et al. 2010). There was no mother's history of drug use or additional risk associated with pregnancy, and this case presented to us at 39 weeks with the suspicion of rFO. Foetal echocardiography showed severe tricuspid regurgitation with right heart cavities and RV dysfunction. The patient was decided to deliver. Postnatal echocardiography showed moderate tricuspid regurgitation, and right heart enlargement was resolved.

Considering the symptoms of chest discomfort after exercise with no obstructive coronary artery disease and especially given the expanding aneurysm and its extension to the proximal right PA, surgery was scheduled. The preoperative echocardiography revealed no PH and no pulmonary valve insufficiency.
