Clinical significance of early or mid-systolic apical murmurs: analysis by phonocardiography, two-dimensional echocardiography and pulsed Doppler echocardiography.

The records of 2,000 consecutive patients who had been examined by auscultation, phonocardiography (PCG), two-dimensional echocardiography and pulsed Doppler echocardiography (PDE) were reviewed to assess the clinical significance of apical systolic murmurs which cease well before the aortic closure sound. Fifty-five patients were verified to have early or mid-systolic apical murmurs. Mitral regurgitation (MR) was detected in 32 patients by PDE (29/32) and/or PCG with methoxamine test (27/32). The degree of MR was judged to be mild by PDE in all cases. Apical systolic murmurs due to MR began mainly with the first heart sound (27/32), were confined to the apex (27/32), and high-pitched (25/32). Their intensity was grade III/VI or less in all cases. Mitral valve prolapse (12 patients) was the most common cause of MR. Other causes were rheumatic mitral involvement in seven patients, dilated or ischemic cardiomyopathy in five, mitral annular calcification in three, and hypertrophic cardiomyopathy in two. The causes of the MR in the remaining three patients could not be identified. Thus, early or mid-systolic apical murmurs are mainly attributable to mild MR which can be diagnosed by careful auscultation, PDE and/or PCG with the methoxamine test.

[Coronary sinus type atrial septal defect diagnosed by two-dimensional color Doppler echocardiography: a case report].

PubMed (1985)

H Takahashi Tatsuo Sakamoto Keiko Amano Yoshiyuki Hada Takeshi Serizawa

This is a case report of coronary sinus type atrial septal defect (ASD) diagnosed preoperatively by two-dimensional color Doppler echocardiography. A 22-year-old asymptomatic woman was admitted for preoperative cardiac evaluation. A cardiac murmur and cardiomegaly had been noted at a routine examination which included electrocardiography and chest radiography, and M-mode echocardiography suggested the presence of a secundum type ASD. Color Doppler echocardiography revealed a left to right atrial shunt flow through the coronary sinus ostium into the right atrium. By peripheral contrast echocardiography, a negative contrast echo from the coronary sinus ostium was observed within the right atrium and persistent left superior vena cava was excluded. At operation, a 2 X 3 cm defect was demonstrated at the interatrial septum in the vicinity of the coronary sinus ostium. This is the first reported case of a coronary sinus type ASD diagnosed preoperatively by color Doppler echocardiography.

本研究は「鉄道シニアパス」が郊外に居住する高齢者の交通行動に及ぼす影響を明らかにすることを目的としている.購入者の余暇活動頻度や内容,市街地利用形態の変化について特に考察する.また一部の被験者に沿線の店舗や施設・イベント情報をメーリングリストを用いて配信し,効果を検証した.ケーススタディ地域とした兵庫県川西市は,能勢電鉄と阪急バス沿線にオールドニュータウン群を有し,ターミナルの川西能勢口駅周辺は商業施設が並ぶ.アンケートの分析結果から,シニアパスは余暇活動と鉄道利用に,メーリングリストは鉄道利用に促進の効果が確認された.鉄道利用に伴って買い物や趣味,交流,余暇活動などの増加がわかった.また,川西能勢口駅周辺と,梅田や宝塚沿線の買い物やスポーツ,交際・交流等がシニアパスにより促進されていた.
