Final answer:
Regurgitant heart disease is generally better tolerated than stenotic heart disease perioperatively. Stenosis causes the heart to work harder to pump blood through rigid valves, which can weaken the heart over time. In contrast, regurgitant heart disease does not strain the heart as much, and can often be managed with medication and lifestyle changes.
Step-by-step explanation:
Perioperatively, regurgitant heart disease is generally better tolerated than stenotic heart disease. In regurgitant heart disease, the blood flows backward from its normal path, which can be detected using a stethoscope and produces a heart murmur. Although regurgitant heart disease may cause some symptoms, it does not strain the heart as much as stenotic heart disease, where the heart has to work harder to pump blood through rigid valves. Stenosis can weaken the heart over time. Surgical intervention may be required if the patient's condition deteriorates, while regurgitant heart disease can often be managed with medication and lifestyle changes.
