Surgical treatment of primary cardiac valve tumor: early and late results in eight patients.

<bold>Background: </bold>To report early and late outcomes of patients with the primary cardiac valve tumor undergoing surgical treatment over a 30-year period in our cardiovascular center.<bold>Methods: </bold>From January 1980 to December 2014, a total of 211 patients with primary cardiac tumors accepted surgical treatments, of which only 8 (3.8 %) were primary cardiac valve tumor patients in our surgical center of cardiovascular.<bold>Results: </bold>The diagnosis was identified by echocardiography preoperatively and pathological analysis postoperatively. All patients underwent intracardiac procedures with extracorporeal circulation. Intracardiac procedures included resection of tumor on leaflet in 2 patients (25 %), resection of tumor and native valvuloplasty in 2 patients (25 %), resection of neoplasm and replacement of native valve with prosthetic valve in 4 patients (50 %). One man was performed a resection of tumor on aortic noncoronary leaflet and a coronary artery bypass graft. Eight cases of primary valve tumor occurred in all of four cardiac valves. The majority of valvular tumor was myxoma in 3 cases (37.5 %), followed by the papillary fibroelastomas in 2 cases (25 %). There were one rhabdomyoma (12.5 %), one lipoma (12.5 %) and one mild malignant sarcoma (12.5 %). The mitral valve was the most commonly original valve (62.5 %). There was pulmonic (12.5 %), aortic (12.5 %) and tricuspid (12.5 %) valve tumor each one patient. There was no death and recrudescence in the series. Follow-up of all patients ranged from 1 to 16 years (mean 7.06 ± 4.24 years). There was no recrudesce and cardiac valve dysfunction.<bold>Conclusion: </bold>The incidence of primary valve tumor was very low. More understanding of the rare disease and widespread use of echocardiography would greatly improve the diagnosis of primary valve tumor in the early stage. Echocardiography could detect millimeters in diameter neoplasms on cardiac valve. The diagnoses were based on imaging findings and the classical triad symptoms associated with the hemodynamic abnormalities, the organ embolism and the systemic symptoms directly from tumors. The intraoperative frozen sections and postoperative pathology analysis provided accurate diagnosis and supported the treatment strategies. Early diagnosis and intervention were keys to reserve the normal original valve function. Prompt surgical resection is necessary to prevent potential critical events. [ABSTRACT FROM AUTHOR]
