[Performance of fragmenting operation for restoration of a correct rhythm while treating the isolated failure of a mitral valve].

Possibilities of application of the proposed procedure for intraoperative restoration of the sinus rhythm while the mitral valve prosthesis (MVP) were studied up. In 161 patients, suffering the isolated mitral valve failure stage IV, a surgical treatment was conducted in Department of surgical treatment of acquired heart failures. The left atrium plasty was conducted in 119 (73.9%) of them with the objective to reduce its size and eliminate the re-entry waves passability. Fragmentation in left atrium was conducted in lowradiofrequency regime of diathermy (25-35 W) in accordance to variant (cut and sew) of operations Maze - 3 and Maze - 4. On a hospital stage 3 patients died (hospital lethality 1.9%). MVP in combination with Maze operation in a lowradiofrequency regime have permitted to restore successfully a correct rhythm in 80.2% of patients on a hospital stage and to stabilize it during 1 year postoperatively.

[Diagnosis and treatment of biatrial myxomas of the heart]. / Diagnostika i lechenie biatrial'nykh miksom serdtsa.

Of the multiple myxomas of the heart (MH) the bilateral myxomas were revealed in 57.1%. Of 4 patients before the operation the correct diagnosis was established only in one. Meticulous data on clinical signs, diagnosis and surgical treatment peculiarities of patients with bilateral MH were adduced. Morphological peculiarities of the tumor were analyzed. Special attention was paid to the necessity of clinical and surgical guard toward revelation of undiagnosed tumors, the choice of optimal approaches to the heart cavities while performing radical operation. Basing on results of histological studying of operational specimen it was established that MH is originated from transformed vessels of interatrial septum.

[Transcutaneous balloon aortic valvuloplasty as the 1st stage of surgical treatment of aortic valve stenosis]. / Primenenie chreskozhnoi ballonnoi aortal'noi val'vuloplastiki na pervom étape khirurgicheskogo lecheniia stenoza klapana aorty.

The results of conduction of transcutaneous balloon aortic valvuloplasty in 99 patients were analysed. After the operation conduction was noted the systolic pressure gradient lowering on aortal valve by 67.8% from the initial one. In 28.3% of patients in such conditions the retrograde blood flow to aorta occurs or enhances, but in 7% of patients only the substantial aortic regurgitation increase by 2 points occurs. The occurrence or enhancement of retrograde blood flow in the aorta is more probable if there is a two cuspid valve and while the two balloon method application. Hospital mortality in the intervention performance had constituted 4%.
