It depends on the cause of the shunt.we find it in congenital heart ailments.reverse shunt rt to lt is more dangerous it may cause cyanosis.we can opine more illustratiously if have clinical scenario & 2d echo reports

Shunt is either bidirectional or lft to right because lt sided pressure is more than right side bidirectional shunt is more worse because both side of heart are at same pressure and rt side of heart is low pressure area

Obviously right to left side is more dangerous as right have low pressure than left
