Transcript

  • 1. Echocardiography -why do we need it?
  • 2. Overview • 90% of echo requests are for LV function assessment – Qualitative and quantitative • Remainder for valvular and structural problems
  • 3. Function • The Heart is a PUMP & forms part of the Cardiovascular system •Right and left side of the heart •Work in synchrony
  • 4. Basic Anatomy of the Heart
  • 5. Chambers • Right Atrium (RA) • Right Ventricle (RV) – Filling Chambers • Left Atrium (LA) • Left Ventricle (LV) – Pumping chambers
  • 6. Vessels • Vessels: – Aorta (Ao) – Pulmonary artery – Inferior & Superior Vena Cava (IVC & SVC) – Pulmonary Veins (PV)
  • 7. Valves • Atrioventrucular • Semilunar
  • 8. Valves • The function of the cardiac valves is to prevent retrograde flow of blood through the heart
  • 9. Septum • Interventricular septum (IVS) • Interatrial septum (IAS)
  • 10. Left Ventricular Walls
  • 11. Coronary Arteries Left Anterior Descending Artery Circumflex Artery Right Circumflex Artery
  • 12. The Cardiac Cycle • Ventricular filling – DIASTOLE – AV valves are opened – SV are closed • • Ventricular emptying – SYSTOLE – AV valves are closed – SV are opened
  • 13. The Heart in DIASTOLE
  • 14. The Heart in SYSTOLE
  • 15. Two-Dimensional Echocardiography (2D) • Access to the heart can be very difficult • Windows available: – Parasternal – Apical – Subcostal – Suprasternal – Transoesophageal
  • 16. Parasternal Long Axis • Right Ventricular Wall • Right Ventricle • Interventricular Septum • Left Ventricle • Posterior Wall • Mitral Valve • Papillary Muscles • Chordae Tendinae • Left Atrium • Aortic Valve • Ascending Aorta
  • 17. Parasternal Short Axis (Aortic Valve Level) • Right Ventricle • Left Atrium • Tricuspid Valve • Pulmonic Valve • Pulmonary Artery • Aortic Valve • Right Atrium
  • 18. Parasternal Short Axis (Mitral Valve Level) • Right Ventricular Wall • Right Ventricle • Interventricular Septum • Left Ventricle • Mitral Valve • Posterior Wall • Pericardium
  • 19. Parasternal Short Axis (Papillary Level) • Right Ventricular Wall • Right Ventricle • Interventricular Septum • Left Ventricle • Papillary Muscles • Posterior Wall
  • 20. Apical Four Chamber • Left Ventricular Apex • Interventricular Septum • Right Ventricle • Interatrial Septum • Left Ventricle • Lateral Wall • Mitral Valve • Tricuspid Valve • Papillary Muscles • Chordae Tendinae • Left Atrium • Right Atrium • Pulmonary Veins
  • 21. Apical Five Chamber • Left Ventricular Apex • Interventricular Septum • Right Ventricle • Interatrial Septum • Left Ventricle • Lateral Wall • Mitral Valve • Tricuspid Valve • Aortic Valve • LV Outflow Tract • Left Atrium • Right Atrium • Pulmonary Veins
  • 22. Apical Two Chamber • Left Ventricular Apex • Left Ventricle • Inferior Wall • Anterior Wall • Mitral Valve • Left Atrium • Pulmonary Veins
  • 23. Apical Long Axis • Left Ventricular Apex • Left Ventricle • Inferior Wall • Anterior Wall • Mitral Valve • Left Atrium • AO
  • 24. SUBCOSTAL
  • 25. SUPRASTERNAL
  • 26. Hands on!!!!!
  • 27. • M-Mode is obtained by placing a cursor through structures of interest in the Heart • Only structures transected by this line are imaged and they are plotted against time to form a tracing M-Mode echocardiography
  • 28. • A graph against time of the position of the reflecting structures of the heart relative to the marker is produced • The M-Mode, or Time Motion, makes accurate measurements of dimensions and velocity of motion M-Mode echocardiography
  • 29. • PLAX or PSAX M-Mode AO/LA
  • 30. • PLAX or PSAX M-Mode MITRAL VALVE
  • 31. • PLAX or PSAX M-Mode LEFT VENTRICLE
  • 32. Hands on!!!!!
  • 33. • To assess blood flow VELOCITY and DIRECTION • PWD is used when the exact location of the blood flow sampled needs to be known • CWD is used when we need to determine the peak velocity of blood flow through a particular valve DOPPLER
  • 34. • Blood flow from the LA to the LV • Diastole • Displayed above the baseline FLOW PATTERNS MITRAL VALVE FLOW
  • 35. • Blood ejected from the LV into the Ao • Systole • Displayed below the baseline FLOW PATTERNS AORTIC VALVE FLOW
  • 36. • Blood flow from the RA to the RV • Diastole • Displayed above the baseline FLOW PATTERNS TRICUSPID VALVE FLOW
  • 37. • Blood ejected from the RV into the PA • Systole • Displayed below the baseline FLOW PATTERNS PULMONARY VALVE FLOW
  • 38. • To assign colors to flow direction and show the entire area of any flow, normal or abnormal, within the Heart • Quick visual search of flow anomalies. • Standard practice is “BART” COLOR FLOW DOPPLER in Echocardiography
  • 39. AORTIC INSUFFICIENCY
  • 40. MITRAL STENOSIS/INSUFFICIENCY
  • 41. Hands on!!!!!
  • 42. PATHOLOGIESPATHOLOGIES
  • 43. Ultrasound in Cardiac Assessments Ultrasound in Cardiac Assessments • Valve Disease • Cardiomyopathy • Endocarditis • Prosthetic Heart valve assessment • Pericardial effusion • Systemic Hypertension • Pulmonary Hypetension • Ischemic Heart Disease • Septal Defects • Tumours
  • 44. Mitral ValveMitral Valve • Disease of the Mitral Valve – Mitral Stenosis – Mitral Regurgitation – Mitral Valve Prolapse
  • 45. Mitral StenosisMitral Stenosis
  • 46. Mitral RegurgitationMitral Regurgitation
  • 47. Aortic ValveAortic Valve • Disease – Aortic Stenosis – Aortic Regurgitation – Bicuspid Valve
  • 48. Aortic RegurgitationAortic Regurgitation
  • 49. Tricuspid ValveTricuspid Valve • Disease – Stenosis – Regurgitation
  • 50. Tricuspid RegurgitationTricuspid Regurgitation
  • 51. PulmonaryValvePulmonaryValve • Disease – Stenosis – Regurgitation
