The relationship between the ascending aortic and left ventricular size after aortic valve replacement.

Results After aortic valve replacement there was a decrease in the ascending aorta and aortic root dimensions (p = 0.001, p = 0.001 respectively). Left ventricular end-diastolic diameter and ejection fraction did not changed significantly after AVR. There were the correlations between the preoperative ascending aortic size and the preoperative and after the first year left ventricular end-diastolic diameter (r = 0.419, p = 0.001 and r = 0.320, p = 0.314 respectively). Postoperatively there was also a correlation between the ascending aortic size and the preoperative and after the first year left ventricular end-diastolic diameter (r = 0.320, p = 0.003 and r = 0.136, p = 0.335 respectively). Discussion/Conclusion In conclusion, in this retrospective study we showed that there was a correlation between the preoperative and postoperative aortic size (ascending aorta and aortic root) and the postoperative left ventricular end-diastolic diameter. Although it is early for definite clinical conclusions, however it is the first study which tried to analyze this relationship.
