[Late results of mitral valve replacement with ball-type and low-profile prostheses].

The discussion covers long-term results of mitral valve replacement with Soviet-made prostheses. Two hundred and sixty-three patients have been under observation, the follow-up periods lasting from six months to five years. A ball-valve prosthesis (MK4-25) was implanted to 125 patients; 138 patients received a low-profile (,) prosthesis. Functional parameters were improved in 86 (69.9 percent) patients with ball-valve implants and in 118 (89 percent) patients with low-profile implants. Ten ball valve implanted patients (8 percent) and 6 (4.3 percent) patients with low-profile prostheses died in the long-term period. The five-year survival of rotation-disc artificial valve recipients was 90 percent, and that of the ball valve-implanted patients, 83 percent.

[Reduction of the incidence of suppurative complications after mitral commissurotomy through the use of pentoxyl and methyluracil].

Clinico-experimental study of the pentoxyl and methyluracil effect upon the natural resistance in mitral stenosis cases is presented together with the findings obtained in the experiments dealing with the healing of the wounds infected with pathogenic staphylococcus. All the control animals developed subcutaneous abscesses leading to the separation of the wound margins. The inflammation of the wound was less pronounced in the animals treated with pentoxyl and methyluracil. The use of pyrimidin derivatives before and during operation and postoperatively resulted in the decrease of the incidence of postoperative suppurative complications.

[Surgical correction of multivalvular defects in patients who had earlier undergone heart surgery].

The article analyses the results of surgical treatment of 45 patients with multivalvular acquired heart diseases which had been previously treated by operation. Stage III (terminal) circulatory disorders were diagnosed in 11 (24.1%) patients. A pathological condition of the tricuspid valve was found in almost all patients with the terminal stage of circulatory disorders. Eleven (24.4%) patients died after the operation. The most frequent causes of the fatal outcomes were: cardiac failure (in 6 patients) and hemorrhage (in 2 patients during the operation and in 1 patients on the 6th post-operative day; the bleeding occurred from varicose veins of the stomach and esophagus). Severe initial circulatory insufficiency was the main factor of operative risk. The criteria of operability must be elaborated for this contingent of patients suffering from severe cardiac insufficiency on the eve of the operation.
