Postoperative outcome in aortic stenosis with diastolic heart failure compared to one with depressed systolic function.
BACKGROUND
In patients with aortic stenosis (AS), the clinical outcome worsens after the development of angina, syncope, and heart failure. This study was performed to elucidate whether the outcome with AS was also poor in patients with diastolic heart failure.


RESULTS
Fifty-two patients who had undergone aortic valve replacement (AVR) for AS were retrospectively classified into 3 groups (G) on the basis of LV ejection fraction (EF) and pulmonary wedge pressure (PWP): G-1) normal LVEF, low PWP (EF > or = 45% and PWP < 16 mmHg; n = 35), G-2) normal LVEF, high PWP (EF > or = 45% and PWP > or = 16 mmHg; n = 8), and G-3) low LVEF (EF < 45%; n = 9). Among these 3 groups, we compared the outcome after AVR. None of the patients died after the operation in AS with preserved LVEF irrespective of the PWP, whereas there were 3 cardiac deaths in AS with low EF irrespective of the PWP.


CONCLUSIONS
In patients with AS, diastolic heart failure developed in addition to systolic heart failure. The development of LV systolic dysfunction in AS was regarded as poor during the postoperative course, but diastolic heart failure did not affect the outcome. The occurrence of heart failure with preserved systolic function may have a slightly better prognosis and may still be suitable for AVR.
