Prognosis
The outcome and prognosis of patients depends on the magnitude of left ventricular (LV) function and symptoms.[28][29] The 5-year survival in patients with normal LV function has been reported as 96% whereas that in patients with reduced LV function is 62%.[29] Long-term improvement in LV function is related to the immediate and short-term (first 6 months) response to surgery. Patients who have an immediate reduction in LV dilatation following surgery are more likely to have short- and long-term improvements in the ejection fraction (EF). Furthermore, patients who have an improvement in EF within the first 6 months following surgery are likely to have further late improvements in LV function after this time. The EF is unlikely to improve in patients who do not have an improvement in EF within the first 6 months of surgery.[28]
