Jean Baptiste de Senac's (1693 1770) Important Work on Cardiology and Valvular Disorders.
In the 18(th) century clinical cardiology was based on pulse examination and auscultation by placing the ear directly on the patient's chest, while diagnosis of heart diseases was done in postmortem examination. In 1749, Jean Baptiste de Senac, physician of King Louis XV, published his work on the heart Traite de la structure du coeur, de son action et de ses maladies. It was the result of years of anatomical and physiological study, in an attempt to illuminate heart and its functions. Senac recognized among several heart disorders, aortic regurgitation, mitral calcification, and mitral regurgitation. His work remained a landmark in valvular pathology and cardiology until the early 19(th) century.
