[Changes in left-ventricular contractility and diastolic rigidity and the dynamics of various indicators of blood circulation in patients after aortic valve prosthesis].
The relationship between the stroke output and parameters relating to left-ventricular contraction and relaxation was examined within the early hours after the implantation of prosthetic aortic valve. Quantitative analysis demonstrated a close correlation between left-ventricular performance and diastolic regidity. Left-ventricular diastolic regidity is shown to make a more important contribution than contractility to the formation of stroke output. For this reasons, a therapy aiming only to improve myocardial contractility in patients after prosthetic aortic valve implantation failed to effectively improve their clinical condition.
