A member asked:

Can performing the valsalva maneuver while weightlifting exacerbate normal leakage across the valves of the heart if a murmur already exists?

Even not weightlifti: Performing a Valsalva maneuver (of which there are 4 phases) can exacerbate the regurgitation of blood in a number of valve pathologies. If a murmur already exists, the augmentation of blood flow across the valve (or diminution of it) can increase (decrease) the intensity of the murmur. It depends on the valve (mitral? aortic?) & phase of Valsalva. Do you have a concern? Discuss on HealthTap Prime

Provided original answer
You don't have to be weightlifting - any Valsalva maneuver can theoretically change the blood flow across a valve, depending on the valve and the type of leakage (stenosis vs. regurgitation).

Yes it could: It is a long explanation but you should continue to breath during lifting and avoid grunting and holding breath
