Background: Cardiogenic unilateral pulmonary edema (UPE) has been reported as an unusual condition and to occur in association with severe mitral regurgitation (MR). However, the prevalence of UPE in patients with severe MR remains unknown.Methods and Results: Among 143 consecutive patients with chordal rupture and significant MR, 38 patients with acute severe MR were studied. The prevalence of UPE was 50% (19 patients); all these patients had right-sided UPE. Eight (21%) patients had bilateral pulmonary edema (BPE). All 8 patients with BPE and 18 of 19 patients with UPE had chordal rupture of the posterior leaflet. All patients with UPE and BPE had severe MR with similar left atrial size. Chest radiographs taken ≤48 h from symptom onset diagnosed UPE in 15 of 19 (79%) patients and BPE in 3 of 8 (38%) patients (P=0.037). Chest radiographs taken >48 h from symptom onset diagnosed UPE in 4 (21%) patients and BPE in 5 (62%) patients (P=0.037).Conclusions: The prevalence of UPE was estimated as 50%; it was most frequently right sided and almost always associated with chordal rupture of the posterior leaflet. UPE is not rare, but common, particularly shortly after the development of acute severe MR caused by chordal rupture.

Background:The geographic distribution of cardiovascular (CV) health-care services has not been assessed systematically.Methods and Results:Data of the Japanese Circulation Society (JCS) annual survey were provided to the JCS working group with the permission of the JCS Scientific Committee. The status of CV practice in 2010 was then assessed in 47 prefectures retrospectively, along with national census and gross domestic product (GDP) data. The surveyed indices included resources (hospitals, beds and cardiologists), burden (number of inpatients), and outcome (CV mortality and autopsy) in each prefecture, which correlated well with respective populations or GDP. Inequality of geographic distribution was evident for pediatrics among the 47 prefectures, according to Lorenz curve, Gini coefficient or the maximum/minimum ratio for each index. According to the Gini coefficients, only the number of inpatients (medical or acute myocardial infarction) and beds for the total number of general hospitals or the hospitals surveyed in the present JCS study were lower than expected with regard to GDP.Conclusions:Geographic disparity of CV resources or burden was larger in pediatrics than in CV medicine or surgery. Improvement of equality in CV practice with regard to appropriateness and quality are the coming challenges for the JCS. (Circ J 2015; 79: 1058–1067)

Background Because of their favorable prognostic effects, angiotensin converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB) and β blockers have become background therapy in dilated cardiomyopathy (DCM). However, there are few reports concerning the long-term prognosis of Japanese patients with DCM in relation to these treatments. Methods and Results One hundred and fifty patients with DCM were divided into 2 groups: group A (n=46) (diagnosis: 1982-1989) and group B (n=104) (diagnosis: 1990-2002). During follow-up period of 6.9±4.8 years, 62 patients died and 1 patient had a heart transplant. The survival rate at 5 and 10 years was 60.9% and 34.8%, respectively, in group A patients, and 80.9% and 65.3%, respectively, in group B patients (p=0.0079). In group A patients, ACEI/ARB or β blockers were less frequently used (p<0.0001), whereas antiarrhythmics (class Ia or Ib) were more often used (p<0.0001). The patients treated with ACEI/ARB and β blockers showed a better survival rate than those without (p<0.0001). The patients with antiarrhythmics showed a worse survival rate than those without (p<0.0001). Conclusion The prognosis of Japanese patients with DCM has significantly improved over the past 20 years. This improvement may be explained partly through the increased use of ACEI/ARB and β blockers and a declining use of antiarrhythmics. (Circ J 2006; 70: 376 - 383)
