The report findings you provided state that he underwent a 3 vessel bypass surgery in which one of the grafts is occluded (the segment of the right internal mammary artery to the PDA (which is the branch off either the right coronary artery or the left circumflex).  Impaired LV function suggests that his heart contracts much less forcefully than a normal heart -- and most likely due to his underlying coronary artery disease (i.e. an ischemic cardiomyopathy).

If he is experiencing further symptoms such as chest pain, shortness of breath, or fatigue, it would be of importance that he sees his primary cardiologist for further evaluation.
