WITH CORRECT SOLUTIONS.

What valvular lesion is associated with early closure of the mitral valve? - correct answer- Aortic Insufficiency

*What parameters are used to assess the severity of pulmonic valve stenosis? - correct answer- Peak Velocity and Peak Gradient

MILD. peak velocity <3 m/s. peak gradient <36 mmHg. right ventricular systolic pressure 25-49 mmHg. ...MODERATE peak velocity 3-4 m/s. peak gradient 36-64 mmHg. ...SEVERE. peak velocity >4 m/s. peak gradient >64 mmHg.

52 to 72 - correct answer- *What is the normal range for ejection fraction in males?

A 63 year old male has a left ventricular EF of 35%, mitral valve E/A ratio 2.3 and E/e ratio of 12 and tricuspid peak regurgitant velocity of 2.6 m/s what is the grade of diastolic dysfunction in this patient? - correct answer- Grade III (if E/A is > 2 then always grade III)

Where is the anterior leaflet of the mitral valve located in the image - correct answer-

Pulse Repetition frequency of the system - correct answer- The Nyquist limit of pulsed doppler is dependent upon which of the following?

which anatomic defects are associated with Tetralogy of Fallot - correct answer- 1. ventricular septal defect (VSD)

• overriding aorta
• pulmonary stenosis /anomalous pulmonary veins
• right ventricular hypertrophy (RV hypertrophy)

*A follow-up echo is ordered on a patient diagnosed with Takotsubo cardiomyopathy. What findings would be MOST RELEVANT from the previous study? choose 2 ; - correct answer- 1. abnormal movements in the walls of the left ventricle. 2 / 3

• ballooning of the lower part of the left ventricle (apex).

*What is one significant benefit of utilizing 3d transthoracic imaging? - correct answer- more accurate ejection fraction and volumes

given a mitral valve pressure half -time of 260 ms the mitral valve area is - correct answer- 0.85 cm2 (220 / 260)

A patients tricuspid regurgitation velocity measures 3.5 m/s and the IVC measures 2.3 cm with greater than 50% inspiratory collapse. What is the patient's right ventricular systolic pressure? - correct answer- 4 (3.5 x 3.5 ) + 8mmhg = 57 mmHg (IVC>2.1 ; Inspiratory collapse>50%)

What control would be used to increase the gain in the far field of an image without impacting the new field? - correct answer- TGC (time-gain composition)

What echocardiographic window will MOST LIKELY give you the best information regarding left ventricular function on a barrel-chested individual with emphysema? - correct answer- subcostal
