Reversal of flow in the pulmonary veins during atrial contraction was detected by transthoracic pulsed Doppler echocardiography in a patient with bicuspid aortic valve and heart failure. The flow reversal disappeared after his recovery from heart failure. Flow reversal during atrial contraction detected by transthoracic Doppler may be a sign of congestive heart failure.

Aortic valve insufficiency may occur in a number of backgrounds. A unique etiology is illustrated in a 53-year-old man with terminal cardiac failure due to ischemic heart and aortic valvular disease. Nodular calcification complicated a congenital bicuspid valve and caused erosion through a valve cusp, producing a chronic cusp defect and valvular insufficiency.

Results are reported of an examination of 8 patients with congenital bicuspid aortal valves confirmed at autopsy. Clinical symptoms of this abnormality of development appear as a result of valvular dystrophy and addition of calcinosis with formation of aortal cardiac failure (most frequently stenosis of the aortic ostium). Aortal cardiac failure is very frequently interpreted as rheumatic or atherosclerotic. The author proposes criteria of during life diagnosis of congenital bicuspid aortal valve pathology.

There have been several recent advances in our understanding of aortic stenosis and in its diagnosis and treatment. Aortic stenosis is now most commonly due to a bicuspid valve. Rheumatic aortic stenosis has become much less common and calcific stenosis of valves in the elderly is a rapidly increasing cause. The prognosis of patients with aortic stenosis can be largely determined by their symptoms, with a mean length of survival of 3 to 5 years for patients with angina, 3 years for patients with syncope, and only 12 to 24 months for patients with heart failure. Virtually all symptomatic patients should be operated on, even those with reduced left ventricular function. The risk of sudden death in asymptomatic adults is low, and thus surgery is generally not needed in these cases. Recently, the noninvasive diagnosis of aortic stenosis has improved dramatically with the advent of two-dimensional and Doppler echocardiography. These techniques provide information on the pressure gradient and can even allow accurate estimates of valve area. Cardiac catheterization is still required, however, to determine the anatomy of the coronary arteries prior to surgery since many patients will have concomitant coronary artery disease. The newest development in the treatment of aortic stenosis is catheter balloon valvuloplasty, which is relatively safe and has shown early promise in reducing the pressure gradient across not increased to the normal range and is significantly less than that following aortic valve replacement. The long-term results of balloon valvuloplasty are still being evaluated.(ABSTRACT TRUNCATED AT 250 WORDS)

Seventy nine patients were operated for aortic regurgitation due to bacterial endocarditis confirmed anatomically at surgery between 1968 and 1984. They were classified into 3 groups according to the stage of endocarditis at the time of operation: progressive endocarditis (21 cases), recent endocarditis (39 cases) and late endocarditis (19 cases). The patients were adults (21 to 70 years) and predominantly male (82 p. 100). Previous valvular disease was found in 38 cases, bicuspid aortic valves were found in 21 cases. Most of the patients operated early (recent progressive endocarditis) had cardiac failure and the surgical indication was nearly always poor haemodynamic tolerance. In addition, this indication was also retained in late forms of the disease in patients usually panci-symptomatic in the presence of signs of increasing left ventricular dysfunction. The aortic lesion was the only pathology in 55 cases and was associated with periannular abscess in 8 cases, septal abscess in 5 cases including one with septal perforation, and mitral endocarditis in 12 cases. Seven patients died during surgery, in low output states in 6 cases (global mortality 8.9 p. 100). The 72 survivors were followed up for an average period of 5 years (4 to 168 months); three patients were lost to follow-up. The actuarial survival rate including the operative mortality was 77 p. 100 at 5 years and 64.6 p. 100 at 10 years. Valve dehiscence was common (52 p. 100); although the perivalvular leak was usually small, in 11 cases it was quite severe and 7 patients had to be reoperated. An excellent functional result was observed in 30 cases, especially in those patients operated early.

A series of 45 adults with severe valvular aortic stenosis underwent echocardiographic examination before surgery. The echocardiographic indices of the severity of the stenosis were reviewed: In M mode: aortic valve opening was only clearly defined and quantifiable in 22 out of 45 cases. In these 22 cases, the separation of the valves was variable in 9 cases; the stenosis was underestimated in 2 cases both of which were unsuspected bicuspid valves; the stenosis were overestimated in 1 case leading to an erroneous diagnosis. In 2D: aortic valve opening was easier to detect than in M mode; it was quantifiable in 16 out of 21 patients (80 p. 100). The subcostal view was particularly valuable in patients with chronic pulmonary disease or with barrel-shaped chests. The 2D examination however, suffers from the same limitations as M mode: variability in the values of aortic valve opening in a third of cases and a general tendency to overestimate the severity of the stenosis. In two cases an erroneous diagnosis of severe stenosis was made in cases of simple aortic sclerosis either because of the inability to visualise a mobile 3rd left anterior cusp in the long axis view or because of artefact due to paravalvular calcification. The most reliable index of severity was the thickness of the left ventricular posterior wall: this measurement was never less than 13 mm, with a mean value of 15,8 +/- 1,8 mm in the 43 patients in whom it was measured. The measurement was also of prognostic significance; paradoxical thinning of the posterior wall and septum was a poor prognostic sign which was associated with cardiac failure and passive dilatation of the left ventricle sometimes shortly preceding sudden death. In the absence of cardiac failure, a posterior wall thickness of less than 13 mm excludes surgical aortic stenosis.

Although nonspecific pericarditis, myocarditis, valvulitis, and coronary arteritis are known as cardiac lesions that accompany rheumatoid arthritis (RA), there have been few reports of the occurrence of clinically severe valvular disease. We report here the case of 69-year-old man with a 25-year history of RA who died of acute left-sided heart failure complicating to aortic steno-insufficiency and angina pectoris. Autopsy findings revealed the coincidence of a congenital bicuspid aortic valve with chronic inflammation, fibrosis and calcification; eccentric hypertrophy and myocardial fibrosis of the left ventricle; 75% luminal narrowing of the proximal portion of the coronary artery due to atherosclerosis, and narrowing of the small arteries of the cardiac muscle due to angitis. It is deduced that the coronary artery lesions, aortic valve lesions and myocardial lesions were aggravated by the bicuspid aortic valve, changes with ageing and corticosteroid therapy.

Based on the findings of 50 patients with infective endocarditis, 37 affecting the aortic, six the mitral and seven both the aortic and mitral valves, in addition to analysis of predisposing factors, prominent signs and symptoms distinctive for the clinical entity were assessed (Tables 1 to 3). Preexistent conditions such as aortic valve lesions including bicuspid aortic valve as well as mitral valve lesions including mitral valve prolapse were proven in 66%. Factors which may have compromised host defense mechanisms such as cachexia and chronic alcohol or intravenous drug abuse were present in isolated cases. In 38% of the patients, a diagnostic or therapeutic manipulation, suspected to have given rise to the bacteremia, antedated the onset of endocarditis. Malaise, fatigue and chills were the most frequent symptoms (Table 4). Fever and cardiac murmurs were observed in all patients, anemia and bacteremia in 74% of the patients, respectively (Tables 4 to 6). In blood cultures, the most common microorganisms were found to be hemolytic and nonhemolytic streptococci accounting for 65% of positive findings, followed by enterococci and gram-negative bacteria each with 14% respectively (Table 6). Congestive heart failure predominated among cardiac complications with its occurrence in 84% of the patients. Valvular ring or myocardial abscess, aortic or sinus of Valsalva aneurysm, occasionally with perforation, were found in 24% of our patients. Coronary embolism was documented in 6%; infection-associated pericarditis was observed only rarely (Table 7). Extracardiac complications involved the skin, central nervous system, spleen and kidneys, respectively, in 20 to 30% of the patients. Complications afflicting the eyes, lungs, gastrointestinal tract and the musculo-skeletal system were seen with a lesser frequency of 0 to 12% (Table 8). The diagnosis of infective endocarditis, rendered highly-probable by the constellation of fever, cardiac murmur, bacteremia and anemia, necessitates, however, confirmation through cardiac examinations. In this respect, electrocardiographic and radiologic findings are of limited value, although they may be useful in the detection of cardiac complications. In 6% of the patients, positive criteria for myocardial infarction were indicative of coronary embolism and, i 30%, atrioventricular or fascicular block suggested the presence of abscess formation (Table 9). As radiologic evidence of heart failure, 74% of the patients were found to have pulmonary vascular congestion (Table 10).(ABSTRACT TRUNCATED AT 400 WORDS)

Echocardiographic (ECHO) findings in 211 consecutive examinations performed at Eldoret Medical Services from August 1992 to May 1994 were analysed. Most patients were referred by physicians from Eldoret and from the surrounding hospitals for assessment of heart failure or a heart murmur. Thirty three echocardiograms were judged as being normal and 177 abnormal. Of the abnormal ECHOs, congenital heart disease accounted for 38.4% while rheumatic heart disease accounted for 40.7%: Of the 68 patients with congenital defects, 21 (30.1%) had ventricular septal defects; 19 (27.9%) persistent ductus arteriosus; five (7.5%) mitral valve; four (5.9%) tetralogy of Fallot; and three (4.4%) atrial septal defects. In addition, there were two (3.0%) patients each with complete atrio-ventricular septal defects, tricuspid atresia, complete transposition of the great arteries, truncus arteriosus, single ventricle and bicuspid aortic valve. Of the 67 patients with uncomplicated rheumatic heart disease, mitral valve involvement alone was seen in 39 (58.2%), mitral and aortic in 26 (38.8%) and aortic valve alone in two (3.0%). Rheumatic heart disease was complicated by bacterial endocarditis in five patients. Nine patients had pericardial effusion. The possible role of colour-flow ECHO as a feasible, non-invasive and, in the long term, cost-effective means of allowing for early detection and timely institution of secondary prophylaxis while rheumatic heart disease is still asymptomatic is highlighted.

In the literature, the mitral valve prolapse and bicuspid aorta have been widely discussed as isolated cases or in association with other congenital heart pathologies or systematic illnesses. Nevertheless, they have not been documented contemporarily in the same clinical case. The following case describes a healthy, young, asymptomatic athlete, who has a double valvular heart failure. The defect is occasionally evident during transthoracic echocardiographic examination. The role of echocardiography is stressed taking into consideration the natural lineage and unfavourable reciprocal effect on cardiac hemodynamics, omitting relative implications of familial pathologies. This method is suggested as the means of suitable evaluation for athletes. In fact, this is the best technique to reveral the most precocious modification of cardiac hemodynamic. Consequently, echocardiography allows us to guide and monitor the most appropriate therapy.
