Venous Stent Migration into Right Ventricle.

Venous stents (VS) are used to treat central and peripheral stenoses. Stent embolization into a cardiac chamber is a rare, yet serious complication. We present a case of a 61-year-old man with a recently stented arteriovenous graft venous stenosis who developed VS migration into the right ventricle, associated with S.

Isolated Pulmonary Valve Endocarditis Complicated With Septic Emboli to the Lung Causing Pneumothorax, Pneumonia, and Sepsis in an Intravenous Drug Abuser.

Intravenous drug users are at increased risk for developing right-sided infective endocarditis involving the tricuspid and pulmonary valves. Isolated pulmonary valve endocarditis in intravenous drug users is very rare, and these patients often have more complications, such as pulmonary embolism, sepsis, and pneumonia. We report a case with pulmonary valve endocarditis and extensive pulmonary complications, including sepsis, septic emboli, pneumonia, and pneumothorax.

Giant coronary artery aneurysm seen on blood-pool study.

An 81-year-old man was incidentally found to have a large pericardial cyst on a chest computed tomography. Before surgical removal, an echocardiogram demonstrated that the cyst was more likely a large (7.5 cm) right coronary arterial aneurysm.

Klippel-Trenaunay syndrome and radial artery coronary graft spasm.

A 75-year-old woman with known diagnosis of Klippel-Trenaunay syndrome presented with acute onset of chest pain, dyspnea and elevated cardiac enzymes. She had triple vessel coronary artery disease on subsequent coronary angiography. Given the unavailability of venous conduits secondary to lower extremity varicosities, coronary artery bypass grafting with radial and internal mammary arterial grafts was carried out.

PQ segment depression in a patient with a benign atrial tumor.

A 56 year-old woman presented with palpitations. Her ECG revealed PQ segment depression and a prolonged QTc. Echocardiogram revealed a 2 x 3 cm right atrial mass.
