A cardiologist recieves a patient who is presenting with chest pain, fatigue and shortness of breathe. Upon examination she finds that valve between the lower left heart chamber and the body's main artery (aorta) is narrowed and doesn't open fully. What valve is this and what is the name of the condition and its resulting effect on blood circulation?
Aortic Valve, Type of Valve Stenosis (Aortic Stenosis) , This stenosis reduces or blocks blood flow from the heart to the aorta and to the rest of the body.
