13. Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis
Abstract Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population. Objective: To evaluate the long-term mortality predictors in patients with a small aortic ann

14. Use of Bovine Pericardium and Sutureless Biological Glue in Left Ventricular Rupture After Mitral Valve Replacement, Five Years of Follow-up
ABSTRACT Rupture of the left ventricular wall after mitral valve replacement is an infrequent but lethal complication. Reporting correction technique of ventricular rupture with bovine pericardium patch secured with glue and without suturing: a 51 years-old female patient, with double rheumatic mitral lesion, severe stenosis and discrete insufficiency, who h

16. Valvopatia mitral em gestantes: repercusões maternas e perinatais / Maternal and perinatal events in pregnant women with mitral valve disease
Os objetivos deste estudo foram correlacionar o tipo de lesão valvar mitral com eventos maternos e neonatais. É um estudo retrospectivo, observacional, realizado na Clínica Obstétrica do Hospital das Clínicas da Faculdade de Medicina de São Paulo. Foram coletados dados de 117 gestações em 111 mulheres com valvopatia mitral e 117 recém-nascidos resul

17. Efeitos hemodinâmicos da ventilação não invasiva com pressão positiva em pacientes com estenose mitral sintomática / Hemodynamic effects of positive pressure noninvasive ventilation in patients with symptomatic mitral stenosis
Background: Continuous positive airway pressure (CPAP) impacts hemodynamic changes in heart failure patients by impending cardiac filling and reduces cardiac afterload by reducing left ventricular transmural pressure. These effects may collaborate for the success of this therapy in patients with pulmonary congestion. However, to your knowledge, no study has

18. Williams-Beuren syndrome: cardiovascular abnormalities in 20 patients diagnosed with fluorescence in situ hybridization
OBJECTIVE: To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS: We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old), assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH) was used to confirm th

19. Supravalvular Congenital Mitral Stenosis
Congenital supravalvular mitral stenosis is a rare malformation characterized by the presence of a shelf-like fibrous membrane, with 1 or 2 small orifices, covering and obstructing the mitral valve. The membrane is positioned closely to the mitral valve (and sometimes it is attached to it); therefore, a preoperative diagnosis is inevitably difficult, even wi

20. Percutaneous mechanical mitral commissurotomy performed with a Cribier's metallic valvulotome. Initial results
OBJECTIVE: To evaluate the immediate results of percutaneous mechanical mitral commissurotomy. METHODS: Thirty patients underwent percutaneous mechanical mitral commissurotomy performed with a Cribier's metallic valvulotome from 8/11/99 to 2/4/00. Mean age was 30.7 years, and 73.3% were women. With regards to functional class, 63.3% were class III, and 36.7%

21. Unsupported valvuloplasty in children with congenital mitral valve anomalies. Late clinical results
OBJECTIVE: To analyze late clinical evolution after surgical treatment of children, with reparative and reconstructive techniques without annular support. METHODS: We evaluated 21 patients operated upon between 1975 and 1998. Age 4.67±3.44 years; 47.6% girls; mitral insufficiency 57.1% (12 cases), stenosis 28.6% (6 cases), and double lesion 14.3% (3 cases).

22. Prognostic factors of rheumatic mitral stenosis during pregnancy and puerperium
OBJECTIVE: To identifity characteristics associated with complications during pregnancy and puerperium in patients with rheumatic mitral stenosis. METHODS: Forty-one pregnant women (forty-five pregnancies) with mitral stenosis, followed-up from 1991 to 1999 were retrospectively evaluated. Predictor variables: the mitral valve area (MVA), measured by echocard

23. Echocardiographic analysis of posterior mitral leaflet movement in mitral stenosis.
Echocardiographic analysis of the movement of the posterior mitral valve leaflet in 60 patients with lone mitral stenosis, 35 patients with aortic stenosis, and 18 patients with aortic and mitral stenosis showed a spectrum of initial posterior mitral valve leaflet movement in early diastole. The classical anterior movement was seen in 36 out of 60 patients w

24. Assessment of rheumatic mitral valve disease. Value of echocardiography in patients clinically suspected of predominant stenosis.
The value of echocardiography as compared with cardiac catheterisation was evaluated prospectively in 33 consecutive patients clinically suspected of predominant mitral stenosis. Patients with clinical signs of accompanying mitral regurgitation, no matter how severe, and patients with clinical findings indicating insignificant aortic valve disease were inclu
