  1. Valvular Heart Disease Gregory Hill, DO Interim CV Fellowship Program Director OSU Division of Cardiovascular Disease

  2. Valvular Heart Disease • Format for this lecture • KNOW COLDfor current test • IMPORTANT CLINICAL INFO know for boards, tests and clinical practice

  3. Spectrum of VHD Aortic Valve Mitral Valve Tricuspid Valve Pulmonic Valve

  4. Spectrum of VHD Regurg Aortic Valve Stenosis Regurg Mitral Valve Stenosis Regurg Tricuspid Valve Stenosis Regurg Pulmonic Valve Stenosis

  5. Spectrum of VHD Regurg Acute Aortic Valve Chronic Stenosis Acute Chronic Regurg Acute Mitral Valve Chronic Stenosis Acute Chronic Regurg Acute Tricuspid Valve Chronic Stenosis Acute Chronic Regurg Acute Pulmonic Valve Chronic Stenosis Acute Chronic

  6. Spectrum of VHD Regurg Acute Aortic Valve Chronic Stenosis Acute Chronic Regurg Acute Mitral Valve Chronic Stenosis Acute Chronic

  7. Spectrum of VHD Regurg Acute Aortic Valve Chronic Stenosis Chronic Regurg Acute Mitral Valve Chronic Stenosis Chronic

  8. Spectrum of VHD Regurg Acute Aortic Valve Chronic Stenosis Chronic Regurg Acute Mitral Valve Chronic Stenosis Chronic

  9. Spectrum of VHD – Right Sided VHD Tricuspid Valve Endocarditis – IV drug abusers or inpt with IVs Carcinoid HD - classically TS TR – common, benign, may be secondary to Pulm HTN Pulmonic Valve Pediatrics – Pulm Stenosis Rheumatic HD – PI (Graham Steel Murmur) Right sided valvular lesions change in intensity with inspiration

  10. Cardiac Physiology 101 Systole AV/PV – opens S1-S2 MV/TV – closes Diastole AV/PV – closes S2-S1 MV/TV – opens

  11. Cardiac Physiology 101

  12. Cardiac Physiology 101 Regurg/ Insuff – leaking (backflow) of blood across a closed valve Stenosis – Obstruction of (forward) flow across an openedvalve SystoleAV/PV – opens-------Aortic Stenosis S1-S2 MV/TV – closes------Mitral Regurg DiastoleAV/PV – closes------Aortic Regurg S2-S1MV/TV – opens-------Mitral Stenosis These concepts are set in stone, it can’t occur any other way, It would be anatomically impossible

  13. Cardiac Anatomy 101

  14. Cardiac Anatomy 101

  15. Valvular Heart Disease Aortic Valve • Aortic Stenosis • Aortic Regurgitation

  16. Aortic Stenosis Etiologies • Congenital 0-30 yrs • Bicuspid 30-50 yrs • Rheumatic 30-60 yrs • Degenerative >60 yrs

  17. Aortic Stenosis

  18. Aortic Stenosis – pathophysiology

  19. Aortic Stenosis – pathophysiology

  20. Aortic Stenosis Physical Exam • Harsh Systolic Ejection Murmur – late peaking • S4 gallop (from LVH) • Sustained Bifid LV impulse (from LVH) • Pulsus Parvus et Tardus (Carotid Impulse)

  21. Aortic Stenosis Symptoms • Angina • Syncope • Congestive Heart Failure (CHF)

  22. Aortic Stenosis

  23. Aortic Stenosis

  24. Aortic Stenosis Diagnosis • Ecg – LAE, LVH • Echo 2D/color doppler –test of choice • Cardiac Cath – helpful, confirmatory, needed if the pt is older – look at the coronaries

  25. Aortic Stenosis Treatment of Symptomatic Aortic Stenosis or Decreased LV Function Medical Therapy – treats the symptoms not the cause Aortic Valve Replacement Bioprosthetic vs Mechanical AVR

  26. Valvular Heart Disease Aortic Valve • Aortic Stenosis • Aortic Regurgitation

  27. Aortic Regurgitation

  28. Aortic Regurgitation Etiologies • Abnormalities of the Leaflets • Rheumatic, Bicuspid, Degenerative • Endocarditis • Dilation of the Aortic Annulus • Aortic Aneurysm / Dissection • Inflammatory (Syphyllis, Giant Cell Arteritis. Coll Vasc Dis-Ankylosis Spondylitis, Reiters) • Inheritable (Marfans, Osteogensis Imperfecta)

  29. Aortic Regurg – pathophysiology

  30. Aortic Regurg – pathophysiology

  31. Aortic Regurg – pathophysiology

  32. Aortic Regurgitation

  33. Aortic Regurgitation Physical Exam • Diastolic Decrescendo Blowing Murmur • Hyperdynamic LV apical impulse • Bounding Pulses • S4, S3 Gallop-advanced AI • Apical Rumble – “Austin Flint Murmur”

  34. Aortic Regurg – Austin Flint Murmur Due to the vibration of the anterior leaflet of the mitral valve as it is buffetted simultaneously by the blood jets from the left atrium and the aorta.

  35. Aortic Regurgitation Diagnosis • Ecg – LAE, LVH • Echo 2D/color doppler –test of choice • Cardiac Cath – helpful, confirmatory, needed if the pt is older – look at the coronaries

  36. Aortic Regurgitation Treatment of Asymptomatic Aortic Regurg Medical Therapy – treats the symptoms not the cause • Serial Check ups with Echos (eval EF, Severity AR) • SBE Prophylaxis • Vasodialators (Nifedipine, ACE-I) • Diuretics Treatment of Symptomatic Aortic Regurg Aortic Valve Replacement Bioprosthetic vs Mechanical AVR

  37. If you're not confused, you're not paying attention. Tom Peters

  38. Valvular Heart Disease Mitral Valve • Mitral Regurgitation • Mitral Stenosis

  39. Mitral Regurgitation Etiologies • Alterations of the Leaflets, Commissures, Annulus • Rheumatic • MVP • Endocarditis • Alterations of LV or LA size and Function • Papillary Muscle (Ischemic, MI, Myocarditis, DCM) • HOCM • LV Enlargement – Cardiomyopathies - • LA Enlargementfrom MR – • MR begets MR

  40. Mitral Regurgitation

  41. Mitral Regurg – pathophysiology

  42. Mitral Regurg – pathophysiology

  43. Mitral Regurg – pathophysiology

  44. Mitral Regurgitation Symptoms • Fatigue and weakness • Dyspnea and orthopnea • Right sided HF • MVP Syndrome (if present)

  45. Mitral Regurgitation Physical Exam • Holosystolic Apical Blowing Murmur • Laterally displaced apical impulse • Split S2 (but is obscured by the murmur) • S3 Gallop (increased volume during diastole) • Radiation depends on the etiology

  46. Mitral Regurgitation Diagnosis • Ecg – LAE, LVH • Echo 2D/color doppler –test of choice • Cardiac Cath – helpful, confirmatory, needed if the pt is older – look at the coronaries

  47. Mitral Regurgitation - SBE Prophylaxis
