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 ...
Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with a mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. [ 22 ]
Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte imbalance, or a heart attack. [ 2 ] [ 3 ] Diagnosis is by an electrocardiogram (ECG) showing a rate of greater than 120 beats per minute and at least three wide QRS complexes in a row. [ 2 ]
The standard PSAX view is at the level of the aortic valve, but moving the probe along the long-axis can review the LV outflow tract, LV at the base, and LV at the midsection. Structures visible: Aortic valve in short-axis Aortic valve dysfunction, aortic sclerosis/stenosis; Tricuspid valve in long-axis; Pulmonary valve in long-axis
In patients with non-severe asymptomatic aortic valve stenosis, increased age- and sex-adjusted N-terminal pro-brain natriuretic peptide levels alone and combined with a 50% or greater increase from baseline had been found associated with increased event rates of aortic valve stenosis related events (cardiovascular death, hospitalization with ...
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]
