Caracterización de las arterias coronarias en corazón de porcino como modelo anatómico didáctico en estudiantes del área de la salud

The human heart has a characteristic supply of irrigation given by two coronary arteries: left and right.  Depending on the route of these arteries, the importance and clinical relationship with the electrocardiogram can be determined, since the branches of the coronary arteries have a different predominance in different irrigation territories. Objectives: This research work has a descriptive approach in which the main structural differences in the irrigation of the human heart and pigs were determined to establish a learning tool for students in the area of health sciences.  Methodology: The study was conducted at the University of Applied and Environmental Sciences (UDCA);  where 28 pig hearts were taken as samples, which were injected with latex and then dissected.  Results: The evaluated arteries of the porcine heart presented a morphology similar to that of the human, but, nevertheless, the posterior interventricular artery showed an anatomical variation with respect to its origin.  The irrigation territory was given by the right coronary artery in all the samples.  It is recommended to use a greater number of specimens to be evaluated
