A 17-year-old woman with mitral and tricuspid valve prolapse and myxomatous degeneration presented puerperal infection by Staphylococcus aureus with clinical picture of sepsis and multiple septic embolism (right eye, left thumb, spleen, and left calf). She underwent total hysterectomy on the 10th day postdelivery and right eye enucleation on the 16th. Temporary total AV block occurred on the 14th day with temporary external pacing during the next couple of days. Acute endocarditis with acute mitral regurgitation was diagnosed on the 13th day, demanding immediate valve replacement. On the 46th day she developed moderate tricuspid valve regurgitation due to another episode of endocarditis. Final clinical discharge took place on the 62nd day after antibiotic therapy completion.

Transesophageal echocardiography (TEE) was introduced recently in France. The aim of this study was to review the diagnostic value of this technique after 8 months' use in our cardiology department. A total of 532 TEE studies were carried out between April and December 1988 in 396 patients (average age 54 years, range 17 to 89 years) at Tenon Hospital. The failure rate was 1.8 per cent (N = 10), over half of which occurred at the beginning of the operator's experience. TEE was particularly valuable compared with the standard transthoracic approach in the following instances: the investigation of mitral stenosis, especially before percutaneous valvuloplasty (N = 75). A left atrial thrombus was demonstrated in 5 cases by TEE vs none by standard echocardiography. There was also a much higher diagnostic sensitivity for small interatrial shunts (40 vs 6) resulting from transseptal catheterisation. In the preoperative investigation of severe mitral regurgitation (N = 29). The etiology was accurately diagnosed in 29 vs 26 cases, and the mechanism of the regurgitation was correctly classified especially in cases of ruptured chordae (15 vs 6 cases). In endocarditis (N = 26) by the visualisation of abscess of the aortic ring (7 vs 1) and vegetations (19 vs 8). In prosthetic valve dysfunction (N = 65) by the demonstration of primary degeneration of bioprostheses (7 vs 4), perivalvular leaks (10 vs 4) and non-occlusive thrombi of mechanical prostheses (3 vs 0). In cases of intracardiac tumours, dissection of the thoracic aorta and atrial septal defects.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to determine the reliability of preoperative transthoracic and transesophageal echocardiography compared with the surgical findings in pure or dominant severe mitral regurgitation with respect to: the evaluation of the lesions, mechanism and etiology; the provision of the type of surgery (valve replacement or reconstruction); One hundred and fifty patients were divided into two groups: Group I (N = 120) in which preoperative assessment included transthoracic echo-Doppler coupled with color Doppler in the last 32 patients; Group II (N = 30) operated recently who underwent both transesophageal and transthoracic echo-Doppler examination. In Group I, the sensitivity of transthoracic echo in the evaluation of the etiological was 86% overall [100% in rheumatic valve disease (N = 28), 86% in degenerative or dystrophic valves (N = 72), 44% in endocarditis (N = 9), 87% in ischaemic dysfunction (N = 8)]. The echo evaluation of the mechanism of the regurgitation was also reliable with the exception of ruptured chordae in which direct visualisation of the rupture was only possible in 19 of the 64 cases (30%). The type of surgery predicted by echo was practiced in 87% of cases.

The authors report the value of Doppler color flow mapping in the diagnosis of late diastolic mitral regurgitation in two patients with severe post-endocarditis aortic regurgitation requiring rapid surgical intervention. Doppler color flow mapping played an essential part in the management of these cases by helping in the diagnosis of late diastolic mitral regurgitation which is known to carry a very poor prognosis in this context.

Aortic stenosis and mitral valve insufficiency are common precipitating causes of infectious endocarditis in older persons. These degenerative cardiac valvular lesions may result from an exaggerated calcification process seen in association with aging. Mitral valve prolapse, especially when noted in an older man, may predispose the person to infectious endocarditis. Infectious endocarditis is harder to diagnosis and treat in older persons, and about half of patients die of the disease or its complications. Prophylactic antibiotics must be prescribed for patients with degenerative cardiac or atherosclerotic valvular defects having dental procedures likely to produce a bacteremia.

This paper briefly reviews the anatomy, epidemiology and clinical aspects of the Mitral Valve Prolapse (MVP), and focuses attention on the association between infective endocarditis and prolapse, particularly after oral surgery. It is recommended that all MVP patients, irrespective of whether they have mitral regurgitation or not, receive correct prophylactic treatment. The pharmacological approach suggested, based on the most recent advances in antibiotic pharmacodynamics, is designed in accordance with specific patient risks.

A 34-year-old man, a heavy drinker, was admitted with a high fever and hematuria two months previously. Surgery was performed for acute sever pancreatitis and postoperatively antibiotics were administered with intravenous hyperalimentation. After discharge he was readmitted and infective endocarditis was strongly suspected because of high fever, hematuria, Osler's nodes, Janeway's lesions, splinter hemorrhages and mitral regurgitation. Penicillin G in combination with Gentamycine therapy was started on the first hospital day. On the second hospital day, blood culture revealed Candida tropicalis so Miconazole therapy was commenced. On the forth hospital day, he underwent surgery for replacement of a mitral prosthesis with a prosthetic valve because he had embolus in the radial artery. Despite intensive antifungal therapy, he showed no improvement in clinical symptoms. Then we changed the antifungal drug from Miconazole to Amphotericin B and 5-fluorocytosine. On the 109th hospital day, his clinical symptoms improved. Antifungal therapy was halted and at present 10 months later, he is healthy.

The capability of transesophageal (TEE) versus transthoracic (TTE) echocardiography as a diagnostic tool in clinical practice was prospectively examined in 86 consecutive cases. A conclusive diagnosis was possible in 95% with TEE, whereas the same result was achieved in 48% by TTE. Specifically, TEE provided a conclusive diagnosis in 14 of 16 cases of infective endocarditis, while TTE gave this result in 4 of the 16 cases (p less than 0.001). Similarly, TEE allowed a conclusive diagnosis in 11 of 11 instances of aortic dissection, while TTE gave this indication in two cases (p less than 0.001). TEE was similarly effective in eight of eight cases of atrial thrombi, whereas TTE gave the diagnosis in three of eight cases (p less than 0.01). In five subjects with intracardiac masses, TEE gave a conclusive diagnosis in all five, whereas TTE was able to diagnose conclusively in one subject (p less than 0.02). In seven patients with mitral regurgitation, TEE gave the conclusive diagnosis in all seven and TTE was able to provide this information in four (p = NS). TEE was able to provide a conclusive diagnosis in four patients with aortic insufficiency, and TTE gave the same information in two of the four (p = NS). In 14 patients with prosthetic valve dysfunction, TEE gave the diagnosis in 12 and TTE gave it in eight patients (p = NS). Both methods gave a conclusive diagnosis in 13 out of 13 cases of mitral stenosis (p = NS). Also, TEE provided a conclusive diagnosis in eight of eight patients with adult congenital heart disease and TTE gave this information in four (p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)

The causes, clinical indications and diagnosis and differential diagnosis of cardiac disorders which may lead to cerebral symptoms are illustrated on the basis of a review of the present day level of scientific research. Principally involved are cerebral ischaemias arising from cerebral embolisms or from reduction of cardiac output in cardiovalvular and myocardial disorders. The incidence of all embolisms of cardiac origin makes up 10% of all ischaemic cerebral infarcts, with auricular fibrillation, irrespective of its origin, mitral stenosis, myocardial infarct, mitral insufficiency and combined mitral valve defects, and, in younger patients, mitral valve prolapse, being, in this order of frequency, of primary clinical significance. The other cardiovalvular and myocardial disorders have, in comparison, a relatively low incidence of cerebral embolisms. Haemodynamically induced cerebral ischaemias frequently occur in the form of complications following acute cardiac arrest, in myocarditis and in case of primary cardiomyopathies resulting from cardiac insufficiency or complicating bradyarrhythmia. They are clinically apparent in the form of syncope, and other impairments of consciousness of various levels of seriousness with and without indications of cerebral origin, extending up to coma. In view of the high incidence of 25% of acute cerebral ischaemias in cases of cardiac disease, not only neurological but also detailed cardiological investigation is vital in all cases for a correct diagnosis and for the selection of a suitable course of treatment. Cerebral complications in bradyarrhythmia and endocarditis are discussed in the context of a review of the relevant literature together with consideration of their epidemiology, aetiology, pathophysiology and clinical profile. Pathological sinus-bradycardia, bradyarrhythmia absoluta, sinu-atrial and atrio-ventricular blockages, carotid-sinus and sick-sinus node syndrome, paroxysmal atrial tachycardia, AV-node tachycardias, and auricular fibrillation and flutter, taken as a whole, lead to cerebral complications affected patients in 5 to 10% of afflictions of the central nervous system occur in 50% of patients suffering from complete AV blockage and, at a not precisely definable frequency, in patients suffering from other bradyarrhythmias. In addition to transitory, uncharacteristic symptoms such as dizziness, vertigo, impairment of vision and balance, presyncope, syncope and Adams-Stokes syndrome dominate the clinical profile. Endocarditis, with an incidence of 0.01 to 0.05% in the overall population, results in central nervous system complications in 12 to 25% of cases on average.(ABSTRACT TRUNCATED AT 400 WORDS)

The heart was studied in 30 persons who died suddenly from natural causes in the driver's seat of an automobile, truck or bus. Twenty had cardiac arrest while driving and the other 10 while sitting in the driver's seat of a parked vehicle. Of the 20 drivers, 16 died from atherosclerotic coronary artery disease (CAD): 12 (75%) had minor collisions and 4 did not. Of the 16 with fatal CAD, an average of 2.3 +/- 0.8 of the 4 major coronary arteries were narrowed greater than 75% in cross-sectional area (CSA) by plaque; of 668 five-mm segments of the 4 major (right, left main, left anterior descending, left circumflex) coronary arteries in 13 of these 16 cases, 27 (4%) were narrowed 96 to 100% and 127 (19%) were narrowed 76 to 95% in CSA by plaque. The remaining 4 drivers died from noncoronary conditions: aortic rupture associated with the Marfan syndrome in 1; cardiac sarcoidosis in 1; thoracic aortic dissection in 1; and severe mitral regurgitation from infective endocarditis, which had healed in 1. The other 10 persons were found dead in the driver's seat of a parked vehicle and 8 of them had fatal CAD. Of the 8 CAD victims, an average of 2.5 +/- 1.2 of the 4 major coronary arteries was narrowed greater than 75% by plaque; of the 283 five-mm segments of coronary arteries in 7 of the 8 cases, 44 (16%) were narrowed 96 to 100% and 69 (24%) were narrowed 76 to 95% in CSA by plaque.(ABSTRACT TRUNCATED AT 250 WORDS)
