Apparently this Naples edition is the second. The first edition (Rome 1728) is GM 2973: 
Giovanni Maria Lancisi (1654 – 1720) 
“Lancisi noted the frequency of cardiac aneurysm and showed the importance of syphilis, asthma, palpitation, violent emotions, and excess as causes of aneurysms. He was the first to describe cardiovascular syphilis. Lancisi shares with Vieussens the honor of laying the foundation of the pathology of heart disease.” 
“…his own work on dilatation of the heart is significant in the history of cardiology. It forms the second part of his De Motu Cordis….” (Thornton pg 54)
 
See also Heirs 448, as well as GM 2731, which notes Lancisi to be the first to describe valvular vegetations, and noting cardiac hypertrophy and dilatation as causes of sudden death.
