    DISEASES OF THE HEART. CASES AND OBSERVATIONS. SECTION I. HYPERTROPHY AND DILATATION. Iypertrophy and Dilatation of the Heart have been long and ustly regarded as conditions secondary in their nature, and de- ciding on some obstruction to the circulation. They may arise rom causes widely different from each other ; but the most usual, as veil as the most important, are the organic affections of the heart; md few of these exist without more or less hypertrophy or dilatation. ?he frequency with which hypertrophy and dilatation occur as com- jlications of the organic affections of the heart, confers an almost miversal importance on them; and the intimacy of their mutual ■elation—for the one probably never exists without the other— uggests the necessity of a careful inquiry into their effects and in- luence. It was the opinion of M. Bertin, and this has been corroborated >y more modem investigations, that hypertrophy, though capable >f giving rise to troublesome and even dangerous accidents, is not n itself a dangerous affection. Dilatation has been esteemed dangerous, chiefly because believed o indicate that obstruction of the circulation has become extreme ; Bind the cause of that obstruction, from which the dilatation arose, Bas been regarded as the cause of all those secondary evils and ■istresses which so invariably occur in the last stage of cases of dis- Base of the heart. Now, I think that an error has been committed Bere, and that the dilatation exerts a material and direct influ- A
