Randomized Controlled TrialEffect of shunt type on echocardiographic indices after initial palliations for hypoplastic left heart syndrome: Blalock-Taussig shunt versus right ventricle-pulmonary artery conduit.
The study objective was to compare echocardiographic indices in infants with hypoplastic left heart syndrome (HLHS) randomized to different surgical pathways. ⋯ Right ventricle size and function do not appear significantly affected by surgical type of initial palliation for HLHS, and this correlates with early outcome. Echocardiographic Doppler findings correlate well with the expected physiologies of the different shunts as these infants progress through initial palliative strategies.

Case ReportsTransthoracic echocardiographic diagnosis of a type C interrupted aortic arch in an adult.
Interrupted aortic arch is the complete loss of luminal continuity between the ascending aorta and the descending aorta and accounts for 1% of all congenital heart disease. Of the affected patients, 75% die within the first month of life and about 90% within the first year if not surgically treated. We report a case of an echocardiographic diagnosis of a type C interrupted aortic arch in an adult who presented with exertional dyspnea and angina after a recent coronary event.

Free-floating right heart thrombi are rare echocardiographic findings usually encountered in patients with massive pulmonary embolism and associated with poor prognosis. We report a case of a large free-floating right heart thrombus without clinically significant pulmonary embolism. The patient was treated conservatively with heparin and warfarin, and the thrombus resolved uneventfully.
