What is Pathology -Aortic Stenosis
Pathophysiology • The flaps of the valve can become thickened, scarred, calcified, vegetated, or fused as AS progresses. • As a result of the sympathetic nervous system being engaged to make up for poor cardiac production, left ventricular hypertrophy develops. Heart failure happens when compensatory systems are ineffective. Evaluation and Diagnostic Results • The existence of a sternal border or apex-down, crescendo-decrescendo, noisy, harsh midsystolic murmur that extends to the side of the neck. At the second right ICS, heard loudest. • Low blood pressure, exhaustion, dizziness or syncope, palpitations, and angina chest discomfort. • The left heart and ventricle are enlarged on the CXR and ECG. • Aortic valve dysfunction, reduced cardiac output, and a lowered ejection fraction are all visible on two-dimensional and Doppler echocardiography. • Cardiac catheterization reveals reduced cardiac production and elevated ventricular pressure. Complications: lung edoema and CHF. Medical Attention and Surgical Procedure • Anticoagulant and prophylactic antibiotic treatment. • Valvotomy in adolescents; valve replacement in seniors. • Tell customers to report any instances of syncope, vertigo, or chest pain right away. • Tell customers to go to the doctor right away if they experience chest pain. • Inform the patient about the significance of continuing anticoagulant medication and attending lab appointments in the event that a valve replacement is done. • Keep track of the INR and PT in patients receiving warfarin treatment and having valve replacement. • Check the CBC for anemia, check the platelet count, and check for bleeding. • On the valves, microorganisms can develop and produce flora that can embolise.
