[Heart failure with preserved left ventricular function: clinical, echocardiographic, and clinical course features. Prognostic factors].
Heart failure is clinically associated with inadequate myocardial contraction, a significant reduction of left ventricular systolic function and ejection fraction and a cardiac enlargement. Some studies have reported that patients with symptomatic heart failure may have an impaired left ventricular filling with a normal or preserved left ventricular systolic function and an ejection fraction > 45%. These patients have a "diastolic heart failure" often neglected or misdiagnosed. ⋯ In conclusion heart failure with preserved left systolic ventricular function is frequent in women with hypertensive heart disease. The prognosis at mean term is better that prognosis of patients with systolic dysfunction but despite medical treatment there is a high morbidity with numerous re hospitalizations. Restrictive left ventricular filling pattern is significantly related to the occurrence of events and mortality.

Case Reports Comparative Study[Major reconstructions of the hip by allograft composite prostheses (long-term follow-up of 34 cases)].
Reconstruction after major resections of malignant tumors can be achieved by association of prostheses and of massive allografts. In 34 patients, we could reconstruct: the proximal femur in 21 cases, after an average resection of 180 mm, with a "composite" allograft prosthesis (with a bone graft around the stem) or a "composite and combined" allograft prosthesis (in which the femur allograft was associated with the trochanteric tendons, to facilitate the reinsertion of the glutei muscles); 10 hemipelvis in which the cup was inserted in an hemipelvic allograft; 3 proximal femurs and acetabulum (with composite cups and stems). ⋯ The association of allografts and prostheses not only allows reconstructions which could be hardly achieved with only prostheses (especially for the pelvis), but also improves functional result and longevity, thanks to the biological fixation of the osseous and tendinous allografts. Considering our 15 years follow up in oncology, we have now extended these procedures to the major bone losses of the femur and pelvis following iterative revisions of standard prostheses for arthritis.
