The Dor procedure requires a hospital stay of approximately 8 days, which is only one day longer than CABG, and the early mortality rate is about 5.6%. Post-operation, the patient does not have any lifestyle constraints other than those associated with CABG. There is a 4% chance the patient will require another cardiac operation; according to Maxey et al., 2004, 18% of patients who underwent CABG had recurrent heart failure. Because the Dor procedure restores the left ventricle to its correct, elliptical orientation, it results in a mean ejection fraction increase of 12.5%. This number continues to improve over the patient’s lifetime, and patients can expect to live an extra 4–10 years, which, according to Maxey et al., 2004, is 3.3% longer than CABG alone with virtually no extra risk.

Famous quotes containing the word results:
“It is perhaps the principal admirableness of the Gothic schools of architecture, that they receive the results of the labour of inferior minds; and out of fragments full of imperfection ... raise up a stately and unaccusable whole.”
—John Ruskin (1819–1900)
“It amazes me when I hear any person prefer blindness to deafness. Such a person must have a terrible dread of being alone. Blindness makes one totally dependent on others, and deprives us of every satisfaction that results from light.”
—Horace Walpole (1717–1797)
“If family communication is good, parents can pick up the signs of stress in children and talk about it before it results in some crisis. If family communication is bad, not only will parents be insensitive to potential crises, but the poor communication will contribute to problems in the family.”
—Donald C. Medeiros (20th century)
