Am J Med Genet ; Jpn J Thorac Cardiovasc Surg ; Case report and literature review. In the intensive care unit, the patient developed pneumonia due to Sthaphylocococus aureus, with bad and long evolution. Tetralogy of Fallot Tetralogy of Fallot is a congenital heart defect which usually involves four anatomical abnormalities of the pukmonar. Echocardiographic examination showed a severe infundibular and pulmonary valve infundibluar in both of them.

This is known as a right-to-left shunt. During surgery a laceration of the pulmonary artery with important bleeding occurred as a complication.

Cardiac catheterization confirmed the echocardiogram diagnosis and an additional stenosis was found at the origin of the left pulmonary artery Figure 2a. Abstract Two pairs of twins with specific concordance in congenital heart lesions are presented. It results in low oxygenation of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the ventricular septal defect, and preferential flow of the mixed blood through the overriding aorta because of the obstruction of the pulmonary stenosis.
