Simultaneously recorded base and apex phonocardiograms and mitral valve echocardiogram (MVE) demonstrating the frequent association of late systolic murmur with a prominent late systolic click. Although the murmur is well transmitted to the base the click transmits poorly. In the first two complexes, an additional softer click precedes theclick murmur complex. The last complex shows only a single click, demonstrating the variability of the auscultatory findings even at rest. The large click occurs at maximal the prolapse and the smaller click occurs near the onset of the echocardiographic prolapse .
