  • A 70-year-old man with aphasia due to ischemic cerebral events by thromboemboli was admitted. The cause of thromboemboli was investigated, and transesophageal echocardiography and chest MRI revealed an encapsulated cystic mass in the right atrium, not circulating. It was a homogeneous cystic mass suggesting a tumor (Myxoma) rather than thrombus. Right atrial mass was resected together with partial atrial septum under the normgthermic cardiopulmonary bypass. Histologically it was an atrial septal aneurysm, closed on itself, filled with blood. We re-port this rarely seen case with a review of the literatures.

  • 생명체 안에는 정맥혈과 동맥혈이라는 두 가지 종류의 혈액이 흐른다. 여기에는 신체 내 세 가지 기관이 관여하는데, 간은 영양과 성장의 임무를 심장은 생명의 원동력을 뇌는 인지와 이성을 담당한다. 영양과 성장은 간에서 형성되는 '정맥혈'을 통해 형성되고 생명의 원동력은 심장에서 형성되는 '동맥혈'을 통해 전신으로 퍼진다. 이 혈액들은 심장으로 다시 돌아오지 않고 온 몸에 퍼져 소비된다. 혈액은 심장이 이완될 때 심장 안으로 빨아들여진다. 심장은 혈액을 펌프질하는 기능이 없으며 동맥이 그 스스로가 '박동성'을 가지고 혈액을 밀어낸다. 좌심실에서 정맥혈과 프네우마(Pneuma)가 섞이게 되는데 심장 오른쪽 심실과 심방의 정맥혈은 좌심실과 우심실 사이 중격(심실중격, interventricularseptum)의 작은 구멍을 통해 좌심실로 이동한다.

  • Purpose : To evaluate late gadolinium enhancement (LGE) pattern of left ventricular (LV) myocardium and presence or absence of LGE in other regions of the heart on cardiac magnetic resonance (CMR) imaging in patients diagnosed with cardiac amyloidosis. Materials and Methods: From 2009 to 2011, 9 patients who were suspected cardiac amyloidosis underwent CMR. We retrospectively analyzed the presence or absence of LGE and enhancement pattern in LV myocardium, and the presence or absence of LGE in other chambers as well. Also we measured interatrial septal thickness (IST), relative signal intensities of atrial septum and epicardial fat over the left atrial (LA) cavity on delayed enhanced images. MRI parameters in these patients were compared to those of control group of patients with ischemic heart disease by Wilcoxon rank sum test. Results: Of nine patients, LGE were found in 8; subendocardial circumferential pattern in 4 and diffuse pattern in 4. LGE in right ventricle was observed in 7. IST was significantly increased in patients with cardiac amyloidosis (P = 0.02). Ratio of atrial septum to LA cavity and ratio of epicardial fat to LA cavity showed a significant difference (P = 0.0002 and P = 0.0006, respectively). Conclusion: In LGE CMR, subendocardial or diffuse enhancement pattern is a typical finding for patients with cardiac amyloidosis. Atrial septum and epicardial fat show relatively increased signal intensities over LA blood cavity.
