Rhabdomyosarcoma is the rare malignant tumor of the heart. A case of a large malignant rhabdomyosarcoma in a 37 year old woman is presented. The tumor arose from the anterior wall of the right atrium and was treated by surgical resection with replacement of the tricuspid valve with bioprosthesis. The patient passed two courses of adjuvant chemotherapy. Six months later transthoracic echocardiography revealed absence of any tissue masses in right atrium, superior vena cava and normal function of the bioprosthesis.
Aim. To study the frequency and validity of posterior aortoplasty for bioprosthetics of the aortic valve.Materials and methods. To study the problem of the required aortoplasty frequency and reliability of the study, 99 patients with Neo-Cor “Uniline” 21-size bioprosthesis implantation were selected. According to the presence/absence of posterior arthroplasty, patients were divided into two groups. In the postoperative period the groups were compared according to the following criteria: left ventricular end-diastolic volume (LV EDV), ejection fraction (LV EF), stroke volume (LV SV), peak and mean valve gradients. Following parameters were calculated stroke volume index (SVI) and valve effective orifice area index (EOAI).Results. There were no significant differences in postoperative data between the groups. In the group without an aortic aneurysm, left ventricular end-diastolic volume (LV EDV), stroke volume (LV SV), peak and mean valve gradients. were slightly larger. In the second group, ejection fraction (LV EF), and peripheral perfusion index were slightly larger. Which with lower gradients on the valve indicates more optimal contractility of the left ventricle.Conclusion. In our practice in all cases, posterior aortoplasty was performed as indicated. Group of patients with aortoplasty demonstrated more optimal left ventricle function. Probably aortoplasty is to be applied more frequently.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
