ABSTRACT
BACKGROUND: The CarboMedics prosthetic heart valve was produced in an attempt to improve the existing valve designs and was especially concerned with easily the implantation and further reduction of turbulence. Precise positioning of the valve in situ was achieved by the abilityof the valve to rotate relative to the sewing ring. Improved monitoring is possible due to increased radiopacity and the dacron sewing ring is coated with carbon to reduce pannus overgrowth. The leaflets have an opening angle of 78 degrees that apparently allows a rapid synchronous closure The aim of this study was to analyze the clinical performance of the CarboMedics valve prostheses(45 mitral 13 aortic and 7 double aortic-mitral valve replacement) were implanted in 65 patients(mean age 48.75+/-9.74 years) RESULT: The operative mortality was 3.1%(2/65) causes of death were low cardiac output syndrome. Total follow up was 1831 patient-months and mean follow up was 29.06+/-10.97 months/patient. No structural failure hemorrhage valve thrombosis and late death have been observed. Embolism occurred at a rate of 0.65%/Patient-year. Actuarial survival and thrombombolism free rate at 36 months were 96.9% and 98.4% respectively. CONCLUSIONS: The CarboMedics valve stands for low valve related complicatons.

The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.
