[Quantitative aspects of the patho-morphogenesis of cor pulmonale after lung resection]

Hearts of 112 randombred dogs after resection of 33-75% of pulmonary tissue were studied macro- and microscopically, by stereometry, and morphological statistical analysis. Pulmonectomies (resection of 58% of pulmonary tissue) and extensive to the development of pulmonary heart. In these cases, the degree of hypertrophy correlates with the volume of the resected lung tissue, the duration of the post-operation period and terminates mostly in heart decompensation of the right type which develops most frequently when there exists a disproportion and unbalanced hypertrophy of various parts of the myocardium.
