Case ReportsScimitar syndrome; an unusual congenital abnormality occasionally seen in adults.
Scimitar syndrome a very rare and variable congenital disorder characterized by an anomalous connection of the pulmonary vein with the IVC. The syndrome is mostly seen in very early infancy, but was now recognized in a 46-year-old woman, who was referred to the outpatient clinic of the department of cardiology with complaints of dizziness. Contrast enhanced computer tomography (CT) showed dextroposition of the heart and a large right pulmonary vein joined the inferior vena cava (IVC) just above the level of the diaphragm. The typical features of the syndrome are discussed.

Case ReportsBiatrial compression caused by intrapericardial hematoma secondary to ruptured type I acute aortic dissection following aortic valve replacement.
Ruptured aortic dissection after aortic valve replacement (AVR) is uncommon and rarely diagnosed premortem. We report a patient with a ruptured type I aortic dissection and biatrial tamponade 2 months after AVR caused by loculated intrapericardial hematoma. The diagnosis was made by transthoracic echocardiography and confirmed at operation.

Coronary 64-slice computed tomographic angiography models employing aortic root and selective catheter directed contrast enhancement in swine: technical feasibility and preliminary results using 3D and 4D reconstructions.
The technical feasibility of combining catheter directed coronary enhancement and multidetector computed tomographic angiography (MD-CTA) is presented in a swine model at various cardiac and injection rates. ⋯ Catheter directed MD-CTA can be performed by retrofitting the current CT scanner with a portable c-arm fluoroscopy unit. S and AR MD-CTA provide high coronary anatomy definition and luminal attenuation without obscuring cardiac chamber signal and with the least iodinated contrast volume.
