Clinical Manifestations
This disorder can being silently, symptoms can appear and the heart can no longer adapt to the increasing resistance to blood flow.
A progressive narrowing that becomes symptomatic over time.
This condition increases resistance against, which the left ventricle must pump.
Chronic pressure overload
Sthethoscope
Interventions can help with these symptoms, but they don't reverse the mechanical obstruction.
Medical therapies for symptom relief
Age degeneration can cause calcium buildup, leading to a stiffened valve.
Calcific degeneration
Patients may report feeling light-headed or fainting during physical activity due to limited blood flow during exertion
Extertional syncope
Over time, the left ventricle responds to increased workload by thickening its muscular wall.
Concentric hypertrophy
This image test is essential for determining valve area, pressure gradients, and overall severity.
Echocardiography
Patients are warned to avoid activities that require straining, as it can be dangerous to this
Cardio output
A congenital version of this disorder occurs when the valve forms with two leaflets instead of three.
Bicuspid valve
A patient may descirbe chest tighness due to the heart muscle not recieving enough oxygen during increased workload.
Angina
Reducing forward flow through the affected valve decreases this essential heart performance measurement
Stroke volume
Electrical tracing may show a sign of increased muscle mass in the left ventricle.
Left ventricular hypertrophy. LVH
An invasive procedure delivers a new valve using a catheter-based method
Transcatheter heart valve replacement, TAVR
The affected valve lies between these two major heart structures.
The left ventricle and the aorta
Pulsus parvus et tardus
The stiffened ventricular wall eventually limits filling, contributing to a specific type of heart failure pattern
Diastolic dysfunction
An invasive study can be used to measure pressures directly within the heart chambers
Cardiac catheterization
Healthy patients undergo this open-heart procedure to replace the narrowed valve.
Surgical valve replacement
The measurement progressively decreases as the condition worsens and makes ejection more difficult.
A systolic murmur that radiates to the neck is characterisits of this disorder.
A mumer casues by an obstruced valve opening.
Obstruction over a long period of time reduces blood flow to this major arterial vessel supplying the body.
The aorta
A chest X-ray can reveal this enlargement because of years of increased workload.
Cardiomegaly
Without corrective intervention, severe cases can progress and lead to a fatal event.
Death from heart failure
A poor prognosis is associated with the onset of this class symptom triad.
Angina, syncope, and heart failure
