[Radical surgical treatment of heart myxoma]

Experience of surgical treatment of 362 patients with the heart myxoma (HM) was summarized. The expediency of application of various approaches in the left auricle (LA) myxoma was analyzed. Significant advantages of application of the approach through the right auricle to reduce the danger of the tumor fragmentation while its excision were noted. There was elaborated and introduced transbiauricle approach to the LA tumor, application of which secures minimal risk of the tumor fragmentation as well as the possibility of adequate heart revision conduction and the processing of full value of tumor bed for any localization. In terms of observation up to 30 years in 5 (17%) of patients the HM recurrency had occurred. Application of the method, which envisages excision of part of interatrial septum, where HM is fixed, in its all thickness with subsequent suturing and plasty of defect using the patch, making additional processing of the tumor bed with iodine solution and diathermocoagulation, had permitted to reduce the recurrency of the disease from 4.3 to 0.5%.
