[Left ventricular behavior following acute right ventricular pressure overload: an experimental study].

Abstract:

:Relationships between biventricular pressures, left ventricular shape and paradoxical septal motion in patients with right ventricular pressure overload (RVPO) are unknown. To clarify these relationships, we measured left and right ventricular short-axis dimensions and ventricular pressures using anesthetized open-chest dogs with pulmonary embolizations. With repeated microembolization, right ventricular systolic pressure (RVSP) increased stepwise from a level of 27 mmHg to the maximum value of 72 mmHg. This elevation caused gradual leftward shift of the interventricular septum (IVS) both at end-diastole and end-systole. Further embolization caused collapse (shock: left ventricular systolic pressure: LVSP < 70 mmHg) with a fall in RVSP. In the state of shock, the rise in right ventricular end-diastolic pressure (RVEDP) and fall in left ventricular end-diastolic pressure (LVEDP) were prominent, and the degree of shift of the IVS became significantly greater at end-diastole than at end-systole, resulting in paradoxical motion of the IVS. There were significant linear relationships between the degree of end-diastolic IVS displacement and end-diastolic transseptal pressure (LVEDP-RVEDP), and between the degree of end-systolic IVS displacement and end-systolic transseptal pressure (LVESP-RVESP) throughout the course of repeated pulmonary microembolization even in the state of shock. In conclusion, abnormal movements of the IVS in RVPO patients indicate the presence of a marked decrease in end-diastolic transseptal pressure due to right ventricular failure.
