Infective endocarditis of main pulmonary artery in tetralogy of Fallot: “Transesophageal echocardiography adds lease of life”.

Infective endocarditis is a rare occurrence in the main pulmonary artery trunk and even rarer in tetralogy of Fallot.

Interventricular septal hydatid cyst: Transesophageal echocardiography as a therapeutic tool during bypass.

Cystic echinococcosis (hydatid disease) arising from infestation with a larval or adult form of the Echinococcus granulosus tapeworm is endemic in certain states of India, but affecting interventricular septum (IVS) solitarily is a scarce phenomenon. We present a rare case of transesophageal echocardiography guided management of IVS hydatid cyst even during cardiopulmonary bypass, which presented with a rather unusual complaint of repeated syncope.
