Valvular heart disease<br />

Aortic stenosis<br />

سؤال Aortic stenosis –most common cause<br />

Features of severe aortic stenosis<br />

- Narrow pulse pressure<br />

- Slow rising pulse, apico-carotid delay<br />

- Delayed ESM (ejection systolic murmer), maximally over RT 2 nd intercostal space.<br />

- LVH or LVF quieter murmur<br />

- Soft/absent S2<br />

سؤال - S4<br />

- Thrill<br />

- Late sign : exertional syncope (=passing out) سؤال if present ,1 st test is echo.<br />

أهم مافى الموضوع Management<br />

1. If symptomatic Aortic valve replacement (AVR)<br />

2. If asymptomatic observe the patient (regular follow up) is general rule<br />

3. If asymptomatic but<br />

- Valvular gradient > 50 mmHg and with features such as left ventricular systolic<br />

dysfunction consider surgery (AVR)<br />

4. Balloon valvuloplasty<br />

Age < 65 y : bicuspid aortic valve<br />

Age > 65 y : aortic calcification<br />

- Is limited to patients with critical aortic stenosis who are not fit for AVR (mainly<br />

infants & children).<br />

5. Trans-catheter aortic valve implantation (TAVI) :<br />

- In adults with sever aortic stenosis who are unfit for open AVR surgery.<br />

Prosthetic heart valves<br />

- The most common valves which need replacing are the aortic and mitral valve.<br />

- There are two main options for replacement:<br />

1. Biological (bioprosthetic)<br />

2. Mechanical<br />
