Questions and Answers


When a patient has aortic regurgitation what is the equation for calculating left

ventricular end diastolic pressure (LVEDP)?


Ans- LVEDP= Diastolic BP- end diastolic AR gradient




Common associated defects with ventricular septal defect


Ans- pulmonic stenosis with VSDs




Common associated defects with sinus venous atrial septal defect


Ans- Partial anomalous pulmonary venous return with sinus venosus ASDs




Common associated defects with Epstein's anomaly


Ans- Secundum ASDs with Ebstein's anomaly

,Common associated defects with bicuspid aortic valve


Ans- Coarctation of the aorta




How do you assess the right atrial pressure based on the size and collapsibility

of the inferior vena cava


Ans- 3mmHg= IVC <2cm & collapses >50%


8mmHg= IVC >2cm & collapses >50%


15mmHg= IVC >2CM & collapses <50%




what is the valve of the coronary sinus


Ans- Thesbian valve




In which chamber would you see a chair network


Ans- seen in the right atrium as fine strands of tissue similar to chord of the

mitral and tricuspid valves

,when is the left ventricular volume the largest


Ans- end diastole




when is the left atrium volume the largest


Ans- end systole




what is the dimensionless index for evaluating aortic stenosis


Ans- represents the ratio of the LV outflow tract (LVOT) time-velocity

integral to that of the peak velocity of the aortic valve jet




difference between aortic valve area measurement and the dimensionless index


Ans- DI does not require the calculation of LVOT cross-sectional area, a major

cause of erroneous assessment and underestimation of AVA.




peak velocity (m/s) for mild aortic stenosis


Ans- <3.0

, peak velocity (m/s) for moderate aortic stenosis


Ans- 3.0-4.0




peak velocity (m/s) for severe aortic stenosis


Ans- 4.0 or greater




mean gradient (mmHg) for mild aortic stenosis


Ans- <20




mean gradient (mmHg) for moderate aortic stenosis


Ans- 20-40




mean gradient (mmHg) for severe aortic stenosis


Ans- greater or equal to 40




AVA (cm^2) for mild aortic stenosis


Ans- >1.5
