Inflammatory Lesion Congenital Abnormalities

Aortic Anerysm

Deform Lesion of Aortic Valve

Vulvar defect Dilatation/tearing of aorta

Incompetent aortic valve

Incomplete Closure of Aortic valve

The blood pump by the left ventricle to the aorta returns

Blood is added to the normally delivered by the left atrium

Arteries compensate by reflex higher pressure

Dilation of the left ventricle

Left ventricle hypertropies

Reflex vasodilation

Dilatation of left ventricle

Left ventricle ⬆ its muscle strengths

Peripheral arterioles relax

Reduce peripheral resistance

⬇ Diastolic pressure

⬇ coronary perfusion

Left ventricle expels move blood volume above normal/⬆ blood volume

⬆ in systolic blood pressure

Fatigue

Rapid rise and fall of pulse

Tachycardia and palpitation

pt. is advice to avoid exertion competitive sports and isometric exercise

ACE inhibitor and calcium channel blocker

Aortic valvuplasty

ECG, Echocardiography

Radionuclide imaging, MRI

Cardiac catheterization

Reinforce all new information & self care instruction for 4 to 8 weeks after the procedure

Instruct pt. on importance of antibiotic prophylaxis
