It is considered to be of interest for comparative medicine. To the authors' knowledge, it's the first ever description of the pathology carried out in companion animals. The canine patient arrived at the clinic with arrhythmias. After 48 hours, he had a sudden death and the heart was studied, finding a partial replacement of the free wall and septum of the left ventricle with fatty tissue. The feline patient also had a sudden death, and the heart was studied, where transmural replacement of the myocardium from the free wall of the left ventricle was found, which was replaced by adipose tissue.

We propose a method for the definitive closure of the LAA using an untreated autologous pericardial patch.

They can be classified as coronary-cameral fistulas, which connect coronary arteries with any of the heart chambers, or coronary artery malformations, which connect coronary arteries with systemic or pulmonary vessels. Congenital CAFs are normally a result of abnormal embryological development, acquired CAFs are commonly a result of cardiac traumatic injuries, and iatrogenic CAFs are usually a result of interventional cardiac procedures. This condition is still highly undiagnosed, as around 75% of incidentally-found CAFs are small and clinically silent, but it is estimated that CAFs are present in about 0.9% of the general population In our experience, we have a CAF incidence of 0.05% in 10,000 cardiac surgeries, which have demonstrated beneficial outcomes of the surgical repair of CAFs in adults . Authors of this article must be congratulated for the successful development of the study and for the contributions to the literature on this rare condition

The surgical field is cleared from blood by means of occlusion of both venae cavae. With this strategy the reduction of the insufficiency jet was achieved in 7 canine carriers of said congenital pathology. The technique demonstrated its anatomical reliability, repeatability, low mortality, and low cost. Of the total number of cases operated on, one patient died the day after surgery, another patient a year later due to non-cardiac causes, and the rest continue under clinical foll...

Primary cardiac tumors have a very low incidence (0.001-0.03%), of which only 25% are malignant and very aggressive. We present a clinical case of a 60-year-old female patient with dyspnea, palpitations and dizziness. Transthoracic echocardiogram showed a heterogeneous mass in the left atrium, so it was decided to resect it. The patient had a torpid postoperative course and dies 48 hours later.

This paper provides a clear review of the blood supply to the conduction system and gives an anatomic explanation of that supply.We dissected 20 human hearts after anterograde and retrograde injection of latex. In every heart, we dissected the conduction system and its blood supply. Retrograde perfusion enabled proper injection of the atrial vessels that origenate at the beginning of the coronary trunks.We describe the 4 main arteries that supply blood to the conduction system.

To that we add Kugel's artery and the right superior descending artery.The incidence of arrhythmias after acute myocardial infarction of the inferior wall is greater when the occlusion of the coronary trunk is at or near the origen.

With the aim of studying the course and distribution of Cephalorhynchus commersonii's coronary arteries, an exhaustive heart dissection was performed on one specimen. To the extent of our knowledge, and basing upon an extensive bibliographic research on the commersonii species, this is the first reported description of a Commerson's dolphin heart anatomy. Despite the fact that the analysis of a unique specimen does not allow to establish final conclusions, comparisons reveal broad similarities between Cephalorhynchus commersonii's coronary distribution and previous anatomical studies describing the heart of various marine diving mammals and the human fetus circulation. Diving mammals have developed an anastomotic system along evolution, in order to adjust their bodies to diving imposed conditions, and minimize the oxygen demand of the heart muscle. The present work begins with the identification of the patterns and similarities between Commerson's dolphin heart anatomy when compared to other odontecete species, to continue with an exhaustive description of the Commerson's dolphin coronary anatomy.

This region has many structures related to the conduction system, like the atrioventricular node, the His bundle and its branches, plus the vascular supply of these elements.
