The left ventricular volume also increases and initially the stroke volume is maintained by the Frank-Starling principle. ... These factors include the afterload, the left ventricular to left atrial pressure gradient and the compliance of the left atrium, and the size of the mitral valve orifice during regurgitation.

Ask another question, I may be able to help!
