Despite of the improvement in exercise performance after heart transplant, it still remains sub- normal when compared with healthy subjects [3]. Car- diac causes as chronotropic incompetence [4] and diastolic dysfunction [5] have been proposed to be related to the post-transplant exercise impairment, but few studies are available about this theme. The study by Abdul-Waheed et al. [6] is very interest- ing and adds important information to what we know about cardiac causes of exercise capacity limitations in heart transplant recipients. This retrospective study investigated the left atrial volume (LAV, n = 50) and its change along one year (ΔLAV, n = 40) in transplant recipients. The main find of the study by Abdul-Waheed et al was the increasing of the LAV along the one year follow-up and the modest correlation between LAV (r = 0.3; p = 0.038) and ΔLAV(r = 0.48; p = 0.002) with VE/ VCO2 slope, what made the authors speculate about the surgical scar between the native and donor atrium. This scar could impair left atrial pump function and induce atrium dilatation to increase its capacity, as a compensa- tory mechanism. In the figure one of the study, it is evident that some patients decreased LAV while the greatest part of patients increased LAV along the follow-up. Maybe if the aut
