- ANSW ER- Directly What wave represents atrial systole on the Doppler tracing of the pulmonary vein? - ANSWER - A wave What grade of diastolic dysfunction is indicated by a low EF and an E/A ratio of over 2? - ANSWER - Grade III Where are the basal segments located in the LV? - ANSWER - Between the AV groove & the tip of the papillary muscle Where are the mid segments loca ted in the LV? - ANSWER - Segment that includes the papillary muscle Where are the apical segments located in the LV? - ANSWER - Between the base of the papillary muscles to the apex How does Doppler evaluation demonstrate that the pulmonary vascular resis tance is normally lower than resistance in the systemic vascular system? - ANSWER - The flow through the aortic valve reaches a peak velocity faster than the flow through the pulmonary valve What is another term for hypereosinophilia? - ANSWER - Loeffler en docarditis; causes endocardial thickening of the inflow tracts and fibrous obliteration of the left & right ventricular apices What is the vertical structure to the right of the aortic arch in SSN that normally demonstrates flow moving away from the trans ducer in systole?

- ANSWER - 4th left When does the TV open & close? - ANSWER - Opens before the MV opens & closes after the MV closes When is the blood volume the lowest in the RA? - ANSWER - Early systole The largest antegrade flow component seen on a Doppler tracing of a normal hepatic vein is identified during which part of the cardiac cycle? - ANSWER - Early systole What is stroke volume influenced by? - ANSWER - Preload, afterload, and myocardial contrac tility How does bradycardia affect diastasis? - ANSWER - It increases the length of it When does the AV open on the EKG? - ANSWER - Approx. 30 -35 ms after the completion of the QRS When does the IVRT occur on the EKG? - ANSWER - After the R wave What does a normal LVOT tracing demonstrate? - ANSWER - A steep acceleration slope, a sharply peaked early systolic max velocity, and a less steep deceleration slope What is the most anterior valve? - ANSWER - Pulmonic When does the MV close on an EKG? - ANSWER - About midway through the QRS after 60 ms has passed The left circumflex supplies the: - ANSWER - Basal and mid anterolateral walls What describes a normal response to exercise testing performed to assess diastolic function of the LV? - ANSWER - Both the E an d E' velocities should increase What coronary artery courses through the anterior interventricular groove? - ANSWER - LAD What is the purpose of the eustachian valve in fetal circulation? - ANSWER - To guide flow through the foramen ovale What secretes th e pericardial fluid? - ANSWER - Visceral pericardium What is the first parameter to consider when assessing a patient for diastolic dysfunction? - ANSWER - The LV EF What does medial cystic necrosis cause? - ANSWER - Dilated aortic root & ascending aorta (breakdown or damage of connective tissue in the large arteries) Most common complication of a septal myectomy? - ANSWER - VSD What happens to the aortic valve in HOCM ? - ANSWER - There will be mid -
systolic notching What best describes the Doppler tracing from within a patient with a PDA? - ANSWER - Continuous flow toward the transducer in systole & diastole Pressure 1/2 time formula: - ANSWER - .29 x decel time How doe s an LV pseudoaneurysm compare to a true LV aneurysm? - ANSWER - Pseudoaneurysm has a higher risk of rupture T/F: MS has no effect on the LVEDP - ANSWER - True (only has in increase in the LAP)
