data obtained with this new technique indicated that ( 1 ) right and left ventricular cavity functions are similar in the normal newborn , ( 2 ) right and left ventricular cavity filling and emptying vary directly with peak rates of septal and ventricular wall thinning and thickening , respectively , and ( 3 ) there is a close time relationship among maximum left atrial dimension , minimum left ventricular dimension , and mitral valve opening .
