  2. Aortic valve area calculation - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_area_calculation

    In cardiology, aortic valve area calculation is an indirect method of determining the area of the aortic valve of the heart. The calculated aortic valve orifice area is currently one of the measures for evaluating the severity of aortic stenosis. A valve area of less than 1.0 cm 2 is considered to be severe aortic stenosis. [1] [2]

    Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient with severe aortic stenosis. Modified from [3]

    Aortic stenosis; In the center an aortic valve with severe stenosis due to rheumatic heart disease. The valve is … surrounded by the aorta. The pulmonary trunk is at the upper right. The right coronary artery, cut lengthwise, is at the lower left. The left main coronary artery, also cut lengthwise, is on the right. Specialty: Cardiac surgery ...

    en.wikipedia.org/wiki/Pressure–volume_loop...

    Aortic stenosis. Aortic valve stenosis is abnormal narrowing of the aortic valve. This results in much greater LV pressures than the aortic pressures during LV ejection. The magnitude of the pressure gradient is determined by the severity of the stenosis and the flow rate across the valve. Severe aortic stenosis results in

    Aortic regurgitation, though obvious using echocardiography visualization, usually does not produce an audible murmur. [citation needed] Stenosis of the mitral valve, if severe, also rarely produces an audible, low frequency soft rumbling murmur, best recognized by a practiced ear using high quality, especially electronically amplified ...

    Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
