Preoperative left ventricular diastolic dysfunction, particularly defined by a flow propagation velocity <40 cm/s, identifies patients at increased risk of left ventricular dysfunction after aortic valve replacement.
What is the association between left ventricular systolic and diastolic dysfunction and immediate post-operative outcomes in patients undergoing aortic valve replacement for aortic stenosis?
This review highlights the importance of assessing both left ventricular systolic and diastolic dysfunction as prognostic factors for immediate post-operative outcomes following aortic valve replacement.
Reports suggested that immediate post-aortic valve replacement (AVR); left ventricular (LV) dysfunction may be an important risk for morbidity and mortality in patients requiring positive inotropic support. Several factors have been identified as significant prognostic factors i.e., LV systolic dysfunction, LV diastolic dysfunction (LV-DD), heart failure and myocardial infarction (MI). Specific to pathophysiological changes associated with AS, markers of systolic LV function (e.g., LVEF) have been extensively studied in management, yet only a few studies have analysed the association between LV-DD and immediate post-operative LV dysfunction This review brings together the current body of evidence on this issue.
Elahi et al. (Wed,) conducted a review in Aortic stenosis with left ventricular dysfunction. Aortic valve replacement (AVR) was evaluated. Preoperative left ventricular diastolic dysfunction, particularly defined by a flow propagation velocity <40 cm/s, identifies patients at increased risk of left ventricular dysfunction after aortic valve replacement.
