We report the case of a patient with persistent cardiac rhythm originating from the superior vena cava (3 cm above the vena cava-atrial junction). It was detected by noncontact balloon mapping before induction of tachycardia and confirmed by conventional contact mapping with image studies. Thus, a 12-lead ECG showing normal ...

The venous drainage of the heart in porcupines (Hystrix cristata) was investigated. Each of the five adult porcupines (three males, two females) was injected with a coloured latex mixture via the V. cava caudalis for the demonstration of the cardiac veins. The dissection of the specimens revealed that the venous ...

Infrahepatic interruption of the inferior vena cava (IVC) is a rare but well-documented finding. In this condition, the IVC between renal and hepatic vein is absent and the hepatic veins directly empty into the right atrium; because of the enlargement of the azygos-hemiazygos vein system, this condition could mimic aortic ...

In a patient with native aortic valve endocarditis, transoesphageal echocardiography yielded a teddy bear appearance which is not reported so far. A perivalvular abscess (right ear), the superior vena cava in cross section (left ear) and the dilated (post-stenotic) aortic root (face) made up the teddy bear. This was not ...

Fenestrating an extracardiac conduit used for total cavopulmonary connection normally requires an additional incision on the right-sided atrium and is time consuming.

A 92-year-old woman with a brain tumor developed swelling of the left lower extremity. Venography showed considerable thrombi from the left common iliac vein to the femoral vein. Following implantation of a temporary inferior vena cava filter, catheter aspiration therapy and catheter-directed thrombolysis were performed. Venography after 3 days showed ...

Malignant neoplasms rarely extend into the inferior vena cava and up to the right side of the heart. Although massive pulmonary tumor embolism occurs relatively rarely, it can be a catastrophic problem. Intraoperative pulmonary tumor embolism and cardiac arrest occurred in a 68-year-old woman while dissecting the inferior vena cava ...

Anomaly of the inferior vena cava (IVC) as a cause of (recurrent) deep vein thrombosis (DVT) is uncommon. We report on a 33-year-old patient suffering from this unusual cause of DVT without the presence of known predisposing factors (immobilization, trauma, surgery, or underlying thrombophilia). Thus, in young patients with recurrent ...

Venous anomalies are not infrequently encountered during aortoiliac reconstruction, because of the complexity of development of the venous system. Retroaortic left renal veins, duplicate inferior vena cava (IVC), and left-sided IVC are occasionally found. Left-sided IVC has been reported with infrarenal aortic aneurysms. We report successful repair of a thoracoabdominal ...
