The document discusses various types of cardiomyopathies and valvular disorders. It defines cardiomyopathy as a disease of the heart muscle and describes the main types as dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy. It provides details on symptoms, diagnostic evaluations, risk factors, treatments, and statistics for each type. The document also discusses various valvular disorders including mitral valve insufficiency, mitral valve stenosis, aortic valve insufficiency, and aortic valve stenosis.

1. Cardiomyopathies & Valvular Disorders Telemetry Course Natalie Bermudez, RN, BSN, MS Clinical Educator for Cardiac Telemetry

30. Mitral Valve Insufficiency The abnormal leaking of blood through mitral valve, from the left ventricle into the left atrium May be caused by stenosis or prolapse of the mitral valve

32. Mitral Valve Stenosis Narrowing of the mitral valve; Results in impedance of blood flow to ventricles Results in decreased ventricular filling = ↓ CO Backflow to Left Atrium = Atrial Remodeling

33. MVS is very commonly caused by atherosclerotic disease which results in calcification of valves Other Causes: Congenital Heart Disease Rheumatic Heart Disease

34. Mitral Valve Prolapse Folding, inversion, and displacement of mitral valve leaflets towards the left atrium

36. Aortic Valve Insufficiency Aortic Valve fails to close completely Causes backflow of blood into ventricle May be caused by stenosis or prolapse of the aortic valve

37. Aortic Valve Insufficiency VENTRICULAR REMODELING: Eccentric Hypertrophy – (ventricular wall thickening with dilatation) Concentric Hypertrophy – (ventricular wall thickening with diminished capacity)

38. Aortic Valve Stenosis The hardening of the aortic valve or aorta itself

39. Aortic Valve Stenosis
