Echocardiography is the initial imaging modality to delineate the cardiac mass. Clinically echocardiographic information about morphology, location, motion and hemodynamic consequences of the tumor is very important for decision making in terms of additional imaging studies and treatment. We present a case of left atrial leiomyosarcoma masquerading as myxoma preoperatively and discuss the echocardiographic features for distinguishing leiomyosarcoma from a benign tumor, such as myxoma.

Coronary artery bypass graft (CABG) intervention, particularly anastomosis site intervention, is challenging for interventional cardiologists. A paclitaxel-eluting balloon catheter (SeQuent Please) is a recently-introduced device capable of delivering paclitaxel homogeneously into the targeted vessel wall. We herein report our experience with two cases. In the first case, coronary angiography showed significant stenosis at the site of anastomosis between the saphenous vein graft and the left anterior descending artery (LAD). In the second case, coronary angiography showed significant stenosis at the site of anastomosis between the left internal mammary artery and the LAD. We performed percutaneous intervention of these CABG anastomoses using paclitaxel-eluting balloon catheters, and obtained favorable angiographic and clinical outcomes.

Spontaneous visceral hemorrhage is a rare complication of systemic lupus erythematosus (SLE). We report here on a 55-year old male with SLE and who presented with acute abdominal pain due to bleeding of the hepatic artery and the splenic artery. Angiography revealed a spontaneous hemorrhage from branches of the hepatic artery and the splenic artery. We report here on a case of spontaneous recurrent non-traumatic hemorrhage of a visceral artery in a patient with secondary antiphospholipid syndrome (APS), and such a condition has not been previously described in a Korean patient with SLE.
