Kaposiform hemangioendothelioma (KHE) is a rare and aggressive vascular tumor that can be associated with a consumptive coagulopathy and thrombocytopenia (Kasabach-Merritt phenomenon). Only one case of an intracardiac KHE has been reported which was treated with surgical excision and then expectant management.We present a patient with an intracardiac KHE which presented as a large mass surrounding the atria, pulmonary veins, superior vena cava, and infiltrating the atrial septum with moderate compression of the superior vena cava and mild compression of the pulmonary veins. This tumor clinically presented as persistent tachypnea and was unresponsive to conventional therapy with vincristine and steroids but responded dramatically to Sirolimus with almost complete regression on follow-up.None of the current treatments for KHE, alone or in combination therapy have been found to be effective in a uniform or reproducible manner. Well designed, preferably randomized trials are required for a better understanding of the appropriate dosage and duration as well as response to treatment and a consensus of first and second line therapies.

Hemoptysis in the children is a rare but serious diagnosis and is even more uncommon in infancy. Mortality is reported and depends on associated illnesses, underlying etiology, and amount of bleeding. A 4-month-old patient presented with significant hemoptysis. Flexible bronchoscopy with differential lavage confirmed the presence and site of origin of hemoptysis. She was managed with cardiac catheterization for embolization of an aorto-pulmonary collateral vessel with immediate complete resolution and no further recurrences. This highlights the importance of cardiac catheterization to detect collateral vessels as a cause for hemoptysis at this age and its successful resolution following embolization.

Pulmonary artery, and rarely aortic, calcifications have been reported in sporadic case reports in the recipient twin of twin-to-twin transfusion syndrome. This presentation is more likely to be secondary to the haemodynamic alterations in the recipient twin, but must be differentiated from idiopathic infantile arterial calcification as the clinical implications, treatment, and prognosis may be drastically different.
