Personally, I thought that dissecting the pig heart was fairly easy. Once you knew which part Mrs. Todd wanted you to cut next, actually making the appropriate cut, without over cutting, was easy.
Dissecting a pig heart does not affect me morally in any way. For one, we were not randomley mutilating the pig. We were using the pigs organ to help us learn the anatomy of a heart. I feel that it is morally wrong to mutilate an animals organ for no reason, but if it is being done for a justifiable purpose, then its acceptable.
Making the cuts into the pigs heart really wasn’t that hard. The only slightly tricky part was making sure not to cut to deep past the walls of the heart, slicing the valves and cutting the chordae tendinae.
Obviously, dissecting a pigs heart provides much less stress and consequences. If a mistake was made on cutting the pigs heart no one was to be affected. If operating on a live patient, one slip could permanently damage the patient. In the situation of a live operation the stress level would be exponentially increased, not to mention the heart you were operating on would be enclosed in the chest cavity and not out lying on the table for easy access.
Dr. Murphy’s lecture was fascinating and provided much insight into what its like to be a cardiovascular surgeon. I think the most interesting part of Dr. Murphy’s lecture was when he was explaining how a heart machine works, and then the pictures of a heart actually hooked up to a heart machine. Dr. Murphy made reapairing heart valves seem incredibly staright forward, yet at the same time tricky and a delicate process. I was surprised to learn that they actually use the valves in a pigs heart to be substituted in a human heart. To me it’s a little unerving and I would rather opt. for the mechanical valve.
Rheumatic fever is a rare inflammatory disease due to untreated or under-treated strep throat. Although it can develop in adults it is most common in kids from the ages of 5-15. It can damage the brain, spinal cord, skin, joints, and most importantly the heart. It can damage the heart so that the valves in the heart need to be replaced. The only way to prevent Rheumatic fever is to treat strep throat quickly with antibiotics. In the United States people almost always are treated with antibiotics when diagnosed with Rheumatic fever, however, in developing countries, this is not always the case and thus there are higher rates of Rheumatic fever.
