[Use of balloon catheters for intraoperative control of resting myocardial pressure during cardioplegia].
Twenty-two patients operated on for aortal, mitral and multivalvular prosthesis under pharmacological cardioplegia were examined for the purpose of monitoring myocardial resting tension by the tensometric method and by using modified balloon catheters. The results demonstrated that the use of the balloon catheters permits making not only qualitative and quantitative assessments of myocardial lesions and a prompt evaluation of the function of the arrested heart but also the initial myocardial contractility and the restoration of myocardial contractility after cardioplegic arrest by controlling the contraction and relaxation myocardial rate.
