Functional mitral regurgitation in heart failure.

Mitral regurgitation commonly occurs in patients with heart failure. Systolic dysfunction is the hallmark of dilated cardiomyopathy. Mitral functional regurgitation is mitral incompetence in the absence of intrinsic lesions of the mitral valve apparatus. Echocardiography can make a major contribution to the diagnosis of cardiomyopathies. A more careful anatomic and hemodynamic evaluation of mitral regurgitation mechanisms is possible with spectral Doppler, color Doppler, three-dimensional echocardiography and transesophageal echocardiography. Functional mitral regurgitation is due to the incomplete closure of mitral leaflets and is based on alterations of mitral annulus, left ventricular dimensions, function and geometry, left atrial dimensions and function. Knowledge of the mechanisms of mitral regurgitation helps us to gain an insight into therapeutic interventions that modify the mechanistic factors. Medical therapy reduces the tethering forces and also augments transmitral pressure; surgical approaches can modify geometric relationships in the left ventricular chamber and resynchronization therapy can improve co-ordinated timing of mechanical activation of papillary muscles.

[Mitral valve prolapse].

Mitral valve prolapse (MVP) is still a clinical challenging problem. In this report, we review the main characteristics of this entity. Epidemiology of MVP, which relies on the diagnostic criteria adopted, and the incidence of complications, both arrhythmic and structural, are influenced by the characteristics of the population studied, which may lead to bias in data interpretation. Even the definition of MVP may differ according to the cardiologist's or cardiac surgeon's point of view. Usually, cardiologists define MVP as the protrusion of all or part of the mitral leaflets into the left atrium, independent of maintenance of coaptation. Therefore, using this definition, mitral regurgitation is considered as a complication rather than a diagnostic criterion. Arrhythmias, either supraventricular or ventricular, are other possible complications, mostly not life-threatening and associated with myxomatous degeneration of the valve. Diagnosis of MVP is based on echocardiography, which provides detailed anatomic and functional evaluation of the affected valve. Leaflet thickness and motion as well as presence and severity of mitral regurgitation can be assessed, with important diagnostic and prognostic implications. Echocardiographic evaluation of the mitral valve requires a systematic approach in order to define the leaflet/scallop involved and the mechanisms of mitral regurgitation. To this aim, three-dimensional reconstruction may add further insights into objective rendering of mitral valve pathology. Finally, surgical timing in mitral regurgitation due to MVP is an evolving issue and the likelihood of surgical repair is a crucial factor in the optimal timing of surgical intervention, especially in asymptomatic patients with severe mitral regurgitation.

Eustachian valve endocarditis: a rare localization of right side endocarditis. A case report and review of the literature.

BACKGROUND: Right-sided endocarditis occurs predominantly in intravenous drug users, in patients with pacemaker or central venous lines and in patients with congenital heart disease. The vast majority of cases involve the tricuspid valve. Eustachian valve endocarditis is an uncommon disease with similar signs and symptoms of the tricuspid valve endocarditis. A series of only 16 cases of eustachian valve endocarditis are reported in the literature. CASE PRESENTATION: We present a case of a 25-year old woman with intravenous drug abuse who had a staphylococcus aureus tricuspid valve endocarditis associated to eustachian valve endocarditis. Transthoracic echocardiography, as first line examination, showed the vegetations on tricuspid and eustachian valve. CONCLUSION: Our case describe an unusual location of right side endocarditis in a intravenous drug abuser. In our case, in accord with other cases described in the literature, transthoracic echocardiography disclosed eustachian valve endocarditis. Antimicrobial management is not altered by the recognition of eustachian valve endocarditis. Antibiotic treatment and duration of eustachian endocarditis depends on the isolated organism and is similar to antibiotic therapy used in native valve endocarditis.

[First-aid treatment for acute myocardial infarction. Experience at the San Camillo Hospital of Rome].

STUDY OBJECTIVE: The aim of the study is to verify: 1) the trustworthiness level of the diagnosis of AMI defined in Emergency Department (ER); 2) the frequency and the effectiveness (length of staying in hospital, mortality rate) of the invasive or not invasive treatment which are implemented in the ER area. METHODS: We have studied the crowding of the patients suffering from chest pain (CP) who asked the ER for assistance during the year 2000 and that of the patients with AMI diagnosed in ER (diagnosis at the admittance and at the discharge from the hospital, therapeutic procedures, staying in hospital, mortality rate). RESULTS: The patients suffering from CP have been the 5.4% of all the patients who reached the ER and were admitted to the hospital more than the patients who reached the ER for all the other causes (41.5% versus 22.1%). In 61.7% of the patients affected by AMI the disease was identified by the physicians of the ER; the invasive treatment has been developed in 67.7% of those patients and the not invasive in 32.3% of the same patients. The mean length of the staying in hospital for the patients who have been treated with PTCA was 10.3 days; on the contrary, the same value for the patients treated with thrombolysis was 13.8 days and the difference was significant at the 0.001 level. The mortality rate during the staying in Hospital was 5.9% in the patients treated with PTCA and 13% in the patients treated with thrombolysis but the difference was not significant because of the little number of the dead patients. CONCLUSION: The sensitivity (62%) and the specificity (100%) of the diagnosis of AMI defined in the ER demonstrate the utility of a Cardiologic Service in ER.
