CHEST, 78: 1, JULY, 1980 3 Barlow JB, Bosman CK, Pocock WA, et al. Late systolic murmurs and no-ejection (“mid-late”) systolic clicks: an analysis of 90 patients. Br Heart J 1968; 30:203-18. 4 Jeresaty RM. Mitral ballooning: a possible mechanism of mitral insufficiency in diseases associated with reduced end-systolic volume of the left ventricle. Chest 1971; 60: 114-5. S Winkle BA, Lopes MC, Go...
Experimental coronary occlusions were carried out in 12 closed-chest dogs to investigate the functional anatomic characteristics of the mitral valve complex during acute myocardial ischemia. Two-dimensional echocardiography was used to assess left ventricular function, the mitral valve complex, and left atrial size. Presence of mitral regurgitation was assessed by left ventricular contrast echo...
This study examines the clinical and surgical outcome of a group of 55 patients (mean age 33 years) with secundum atrial septal defect who underwent surgical repair of this defect between 1981 and 1990. A group of 25 of these patients underwent late echocardiographic follow-up. Fifty-two patients underwent repair by direct suturing and three by patch closure. Surgical mortality was nil. There w...
Echocardiography was performed in 25 consecutive patients with angina pectoris and angiographically demonstrable coronary artery disease. Left ventricular echograms detected late or pansystolic mitral valve bowing suggesting of mitral valve proplapse in 6/25 (24%). Left ventricular angiography showed prolapse of the posterior mitral leaflet in 15/25 (60%), including 5 detected by echocardiograp...
The prevalence and clinical significance of aortic valve prolapse were determined prospectively in 2000 consecutive patients undergoing routine clinical cross sectional echocardiography. Two hundred and twelve patients were excluded because the aortic cusps were not adequately visualised. Aortic valve prolapse was defined as downward displacement of cuspal material below a line joining the poin...
THE PROLAPSED MITRAL VALVE, or clickmurmur syndrome, continues to evoke interest, concern and controversy. Although the midsystolic click and late systolic murmur were well described in the late 19th century,1 it was not until 1961 that Reid2 suggested the mitral valve as the cause of the click and mitral insufficiency as the cause of the murmur. This was confirmed by angiocardiography and phon...
Marcus-gunn phenomenon is a congenital and sometimes hereditary anomaly, in which a ptotic eyelid retracts momentarily when the mouth is open, or the jaw is moved. These associated movements attributed to abnormal connections between the central mechanisms innervating the pterygoid and elevator muscles. Sometimes this anomaly is associated with dual,s retraction syndrome, duplex kindneys and ur...
purpose : to determine the efficacy of three therapeutic regimens for the treatment of amaurosis fugax secondary to embolic sources from the heart methods : sixty patients randomly divided into 3 groups (20 patients in each group). group 1 received 100 mg aspirin/day, group 2 received the same dose of aspirin plus dipyridamole 75 mg twice daily and group 3 received 10 mg warfarin for 3 days fol...
Mitral valve prolapse is not commonly on the list of differential diagnosis when a patient presents in the emergency department (ED) in severe distress, presenting with non-specific features such as abdominal pain, tachycardia and dyspnea. A healthy 55-year-old man without significant past medical history arrived in the ED with a unique presentation of a primary mitral valve prolapse with an at...
The tricuspid valve was studied in 143 subjects using two dimensional echocardiography. The groups studied were 40 normal subjects, 31 patients with mitral valve prolapse, 22 with clinically probable tricuspid valve prolapse, 20 with congestive cardiac failure, and 30 with miscellaneous cardiac conditions but no features of right heart disease. Using multiple views it was possible to record all...
