LUTEMBACHER'S SYNDROME

Fig. 1. TTE PLAXV shows thickened mitral leaflets with mild restriction of motion and 
doming of AML.  A mean diastolic pressure gradient of 5 mmHg across the mitral 
valve was obtained by Doppler echocardiography.  MVA by P1/2 T was 2.8 cm2. 
Color Doppler showed moderate MR.

Fig. 2. TEE showed moderate sized ASD (white arrows) Calculated QpQs 2.3:1   

Fig. 3. TEE color Doppler clearly shows flow (arrows) from LA to the RA through ASD.

Abbreviations: MVA = mitral valve area, P1/2T = pressure half-time, ASD = atrial septal defect, LA = left atrium, RA = right atrium, RV = right ventricle, LV = left  ventricle, Ao = aorta, LVOT = left ventricular outflow tract.
