[Narrow aperture of aorta in combined prosthesis of mitral and aortic valves].
Results of treatment of 520 patients consequently operated on in the clinic for combined mitral-aortal failure were summarized. All the operations were performed using artificial blood circulation and moderate hypothermia (28 ... 32 degrees C). The defense of myocardium was done using medicinal combined ante-retrograde cooling cardioplegia. While performing the analysis there was established the presence of dependency between hospital lethality and the fibrous ring size (FRS) of the aortal aperture (AA). In late follow-up period after the operation the most low frequency of good results was noted in patients with narrow FRSAA (lesser than 24 mm).
