Echocardiography for the Primary Care Practitioner
• Educational Objectives:
– Understand the Bernoulli and Continuity equations and how they may be used to assess valvular disease – Recognize echo techniques to assess the severity of mitral regurgitation and their limitations – Describe what factors determine whether a pericardial effusion promotes tamponade and echo features that would support this – Appreciate the utility of echo in diagnosing and following patients with cardiomyopathies – Understand the role of exercise echo in predicting cardiac risk – Relate which echo technique is most …show more content…
The peak gradient through the aortic valve is 30 mm Hg. This finding represents what degree of aortic stenosis?
– – – – A) Mild B) Moderate C) Severe D) Unknown
Pre Test
• 2) A young woman with a history of a heart murmur and a mid systolic click has an echo study performed to assess for mitral valve prolapse. What echo view is most appropriate to make this diagnosis?
– – – – A) Parasternal long axis B) Parasternal short axis C) Apical four chamber D) Apical two chamber
Pre Test
• 3) A breast cancer patient has significant shortness of breath symptoms and echo reveals a moderate sized pericardial effusion. Which of the following echo features does not support tamponade physiology?
– – – – A) Right atrial systolic collapse B) Right ventricular diastolic collapse C) Inferior vena cava collapse D) Marked respiratory variation of tricuspid valve inflow
Pre Test
• 4) The following echo features are noted in a patient with shortness of breath and dyspnea. Biatrial enlargement; normal left ventricular size, function, and wall thickness; mitral valve inflow Doppler with a tall E wave. Which type of cardiomyopathy do these findings …show more content…
• EF postop decreased significantly (50% v 58%) • Postop LV dysfunction was common (41%) and carried a poor prognosis (38% v 69% 8 year survival) • Preop echo variables were predictive of postop EF (preop EF, systolic diameter)
