CAS 2150 Exam 2 Review

Front

What is the peak or maximum pressure gradient through a valve with a velocity of 5.0 m/s?

Back

100 mmHg

Front

What does severe aortic stenosis (AS) indicate when associated with aortic insufficiency (AI)?

Back

Severe AS is shown with AI.

Front

Is an AV area of 1.7 cm² considered normal?

Back

False

Front

What measurements demonstrate severe aortic stenosis?

Back

AVA of 0.6 cm², 5.2 m/s, Max PG of 100 mmHg - all of these.

Front

What can happen to the mitral valve (MV) if aortic insufficiency (AI) is severe enough?

Back

It can close prematurely.

Front

Define aortic stenosis (AS).

Back

Aortic stenosis is a condition where the aortic valve narrows, restricting blood flow from the heart.

Front

What is the normal range for aortic valve area (AVA)?

Back

Normal AVA is typically greater than 2.0 cm².

Front

What is the significance of a maximum pressure gradient (PG) in assessing valve function?

Back

A higher maximum PG indicates greater obstruction and severity of valve disease.

Front

What are the common symptoms of severe aortic stenosis?

Back

Symptoms include shortness of breath, chest pain, and syncope.

Front

What is the relationship between aortic stenosis and left ventricular hypertrophy?

Back

Aortic stenosis can lead to left ventricular hypertrophy due to increased workload on the heart.
