Essential echocardiography : A practical guide
A Practical Handbook serves as today's premier practical guide to the understanding of the most commonly used cardiac imaging technique in the world. The perfect marriage between anatomy and physiology, the text covers emerging cardiac imaging technologies, advances in ultrasound technology, as well as new techniques and applications of cardiac ultrasound. Essential Echocardiography: A Practical Handbook provides the physiological, anatomical, and diagnostic grounding for all students of cardiac ultrasound, as well as a sound basis for a more general understanding of cardiac imaging.
Aortic valve disease
Your heart has four valves to keep blood flowing in the direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (epiphysis or leaflets) that opens and close once during each heartbeat sometimes the valve do not open or close completely; this interferes with the flow of blood inside the heart, and may lead to impaired ability to pump blood to your body. In aortic valve disease, the aortic valve between the lower left chamber (left ventricle) and the primary artery that delivers blood from the heart to the body (the aorta) does not work completely. It may not close completely; This causes blood to leak back into the left ventricle (regurgitation), or possibly narrowing of the valve (stenosis).
