Abstract

SummaryA 62-year-old man presented to hospital with chest oppression. Coronary angiography revealed total occlusion of the right coronary artery and inferior myocardial infarction was diagnosed. He was treated by percutaneous coronary intervention with stenting for myocardial infarction. After four months, echocardiography revealed a huge aneurysm protruding below the inferior surface of the left ventricle. It was considered to be a pseudoaneurysm from the echocardiographic findings. The patient had no symptoms and he refused surgery, so progression of the aneurysm was monitored carefully. At seven months after revascularization, the aneurysm showed a marked increase in size, with a maximal diameter of 48mm and orifice diameter of 22mm. Accordingly, the patient agreed to undergo surgical excision. The aneurysm was resected and the defect was closed with a pericardial patch. Pathological examination revealed all of the myocardial elements in the aneurysm wall and thrombus in its lumen. In conclusion, this was a rare case of venricular subepicardial aneurysm.

Abstract

SummaryBackgroundClinical features of diastolic heart failure (DHF) have not been well characterized, leading to an inaccuracy in the diagnosis of DHF. Recently, the ratio of transmitral E velocity to early diastolic mitral annular velocity (E/E′) has been shown to be useful to assess LV filling pressure.PurposeWe tested the hypothesis that persistent elevation of E/E′ ratio is one of the characteristics of patients with DHF.MethodsCandidates of this study were 89 patients who presented to the emergency department because of acute pulmonary congestion. Those with an ejection fraction of >45% on admission comprised the DHF group (n=18). A control group consisted of consecutive 30 hypertensive patients with an ejection fraction of >45%. Doppler echocardiographic data were obtained with plasma BNP measure in the chronic stage >6 months after the emergent admission.ResultsThe E/E′ ratio was higher in the DHF group than in the control group (16.7±2.8 vs. 9.4±3.3, p
