The term 'Artificial Heart Ventricles' refers to the synthetic replacement for the human heart's natural ventricles. The spelling of this word can be broken down phonetically as follows: /ɑːtɪˈfɪʃ(ə)l hɑːrt ˈvɛntrɪk(ə)lz/. The 'ai' in 'artificial' is pronounced like the long 'i' sound in 'eye'. 'Heart' is pronounced with a silent 'h' and a long 'a' sound. 'Ventricles' is pronounced with the emphasis on the first syllable and the 'c' is pronounced like a 'k'.
Artificial Heart Ventricles refer to mechanical devices that are designed to function as a replacement for the natural ventricles of the heart. Ventricles are the two lower chambers of the heart responsible for pumping oxygenated blood to the body's organs and tissues. In certain cases of heart failure, when the heart is unable to effectively pump blood, artificial heart ventricles may be used as part of a medical intervention to support and sustain the patient's cardiovascular system.
These devices are typically made from biocompatible materials and are implanted into the patient's chest cavity through surgical procedures. Artificial heart ventricles are connected to the heart's chambers and blood vessels, enabling them to assist or entirely replace the pumping action of the natural ventricles. They are powered by an external system that propels blood flow, with the mechanical pumping action closely mimicking the physiological functioning of the human heart.
Artificial heart ventricles are often used temporarily, serving as a bridge to heart transplantation for patients waiting for a suitable donor heart. They can also be utilized as a long-term solution for individuals who are not eligible for a heart transplant. In such cases, these devices, known as ventricular assist devices (VADs), can significantly improve the patient's quality of life and extend their lifespan.
Overall, artificial heart ventricles exemplify the advancements in medical technology and highlight the possibilities of mechanical support to supplement or replace vital organ functions.
