Case ReportsAtrial septal defect with right to left shunt despite normal pulmonary artery pressure.
A 74 year old woman had right to left shunting through an atrial septal defect despite normal right heart pressures. Acute volume expansion temporarily reduced the shunt. Contrast echocardiography and angiography demonstrated that this shunting occurred almost exclusively from the inferior vena cava. At surgery a redundant flap of septum secundum was found that was adjacent to the inferior vena cava orifice, intercepting its blood return like a spinnaker and shunting it into the left atrium.

Case ReportsTwo-dimensional and Doppler echocardiographic diagnosis of an aortic to right atrial fistula complicating aortic dissection.
A 60 year old woman presented with massive aortic root dilation and sudden cardiovascular collapse 10 years after aortic valve replacement. An aortic to right atrial fistula was diagnosed by echocardiographic imaging and Doppler ultrasound. At operation, the patient was found to have chronic aortic dissection with aneurysm formation. Rupture of the aneurysm into the right atrium was confirmed.
