Aims

To overcome numerous contradictions in the knowledge of the blood transportation, a hypothesis was supposed asserting the swirling pattern of blood flow in the heart and main vessels which resembles tornado-like flows and which is widespread in nature. These flows can be exhaustively described by the exact solutions of the nonstationary hydrodynamic Navier-Stokes equations and the continuity equations for the class of viscous swirling flows offered by Kiknadze - Krasnov.

Materials and methods

Using morphometric studies of human and canine left ventricular casts and Multislice Computed Tomography it has been shown that the trabeculae in the ventricular cavity are oriented along the streamlines of the tornado-like flow of appropriate dimension. Moreover, this principle covers both the diastolic trabeculae of the inlet part of the left ventricle and the systolic trabeculae of the outlet part of the left ventricle.

Results

It is concluded that the main trabeculae function consists in the structural organization of the intraventricular tornado-like swirling flow of Kiknadze – Krasnov type.

Conclusion

The hydrodynamic analysis of the blood flow laws is indispensable for the development of new diagnostics criteria in cardiology, cardiac surgery optimization, the design of new implantable and paracorporal devices contacting with blood flow and mathematical and physical modeling of circulation.
