Surgery>>>>>Surgical Considerations in the Elderly
Question 7#

In elderly patients undergoing heart valve replacement, bioprosthetic valves are preferred over synthetic valves because:

A. There is less need for anticoagulation which is hazardous in the elderly
B. The operative time is shorter which reduces the risk of pulmonary complications
C. Synthetic valves have a higher incidence of manufacturing defects
D. The extent of hemolysis is less with bioprosthetic valves

Correct Answer is A

Comment:

Prolonged anticoagulation is more hazardous in the elderly where the risk of falls is increased. Even a fall from the standing position can result in a fatal intracranial bleed in an anticoagulated patient.
