[Cooling of the myocardium: clinical comparison of 2 methods of administering the cardioplegic solution].
The authors studied the dynamics of changes in myocardial temperature in injection of an oxygenated cardioplegic solution through the root of the aorta (group 1 of patients) and through the right atrium (group 2) during prosthetic repair of the heart valves. Retrograde injection of the cardioplegic solution through the right atrium ensured adequate cooling of the hypertrophied myocardium of both ventricles and did not yield to antegrade infusion. It proved possible to attain a safe level of right-atrial hypothermia only when the cardioplegic solution was infused through the right atrium. This is due to the fact that the method combined the features of perfusion and local hypothermia.
