The correct spelling of "Surgical Valves" involves a few phonetic intricacies. The pronunciation of "surgical" is /ˈsərdʒɪkəl/, where the "g" sounds like a "j" due to the following vowel "i". In "valves", the "v" sound is /v/ and the "a" is pronounced as /æ/, which is a short "a" as in "cat". The "l" is silent, and the final "es" is pronounced with a soft "z" sound, /ɪz/. Therefore, "Surgical Valves" is spelled /ˈsərdʒɪkəl vælvz/.
Surgical valves are mechanical devices that are used in cardiac surgery to replace damaged or diseased heart valves. The heart valves are responsible for regulating blood flow through the chambers of the heart and ensuring the unidirectional flow of blood. However, if a valve becomes damaged or is affected by a disease such as stenosis (narrowing) or regurgitation (leakage), it can impede the efficient flow of blood and compromise the overall function of the heart.
Surgical valves are artificial replacements that can be made from various materials, including metal, plastic, or biological tissues such as animal or human donor tissues. There are mainly two types of surgical valves: mechanical valves and biological valves.
Mechanical valves are composed of synthetic materials and require lifelong anticoagulant therapy (blood-thinning medication) due to their tendency to cause blood clot formation. These valves are durable and long-lasting, but they may also produce audible clicking sounds. On the other hand, biological valves are made from animal or human tissues and do not require long-term anticoagulation therapy. However, they have a limited lifespan and may need to be replaced after several years.
The selection of a specific surgical valve depends on various factors such as the patient's age, lifestyle, and overall health. Surgeons consider factors such as durability, potential for complications, and the need for anticoagulant therapy when choosing the most suitable surgical valve for a patient.
In conclusion, surgical valves are artificial devices used in cardiac surgery to replace damaged heart valves. They assist in restoring the normal blood flow through the heart and are available in two types: mechanical valves and biological valves, each with its own advantages and considerations.
The word "surgical" originated from the Latin word "surgicalis", which is derived from the Latin term "surgere", meaning "to rise" or "to lift". In English, "surgical" refers to anything related to surgery, specifically the use of medical operations or techniques to treat a condition or disease.
The term "valve" comes from the Latin word "valva", meaning "a folding door" or "a hinge". It evolved to describe a device that controls the flow of fluid, such as in plumbing or mechanical systems. In the medical field, a valve refers to a structure that controls the flow of blood or other bodily fluids in the body.
Therefore, "surgical valves" can be defined as devices used in surgical procedures to control or regulate the flow of fluid within the body, such as cardiac valves used in heart surgeries.
