When you listen to a beating heart, you will notice two sounds (“lub” and “dub”). The first sound (“lub”) is when the mitral and the tricuspid valves close at the same time. The second sound (“dub”) is due to the closing of the pulmonary and the aortic valves at the same time. In some heart conditions, one might hear an extra sound between the “lub” and the “dub” sounds.

In some heart conditions, one might hear a split sound during the “lub.” Which of the following choices is the most plausible explanation for the extra sound?
