the case we have described shows that ( 1 ) the early diastolic sound ( tumor plop ) coincided with maximal excursion of the tumor in the left ventricular inflow tract , ( 2 ) tumor movements during mid to late diastole corresponded to low-frequency oscillations in left ventricular pressure , ( 3 ) tumor expulsion from the left ventricle into the left atrium was initiated during `` '' isovolumic '' '' contraction but continued into the early ejection phase , ( 4 ) mitral valve closure was abnormally delayed until after the onset of aortic ejection , and ( 5 ) systolic ejection was initiated before coaptation of the mitral valve leaflets .
