1. A Complete Occlusion of Right Coronary Artery Due to Stanford Type A Aortic Dissection - Successful Treatment with Extracorporeal Membrane Oxygenation (ECMO)
Abstract We present a patient diagnosed Stanford Type A aortic dissection, who was misdiagnosed as acute myocardial infarction for 5 days. In the surgery, the right coronary ostium was totally occluded, and the right coronary artery (RCA) was bluish from the trunk to branches. The true lumen couldn’t be found when we opened the RCA. We had to give up coron

2. Alterações anatomopatológicas em corações de camundongos submetidos à inalação crônica de cocaína crack / Anatomopathological alterations in hearts of mice submitted to chronic inhalation of crack cocaine
Crack cocaine is the currently popular form of cocaine, due to its low cost and rapid effects on the central nervous system. Alterations caused by cocaine on the hearts of humans and animals are well known and severe disorders in the cardiovascular system, which are sometimes fatal, are frequent. Considering the growing concern regarding the increase in the

3. Origem, trajeto, ramificações e distribuição dos ramos ventriculares da artéria coronária direita no macaco prego (Cebus apella)
Comparative Anatomy of mammals has been a relevant subject of researches in biomedical and biological areas with the objective of looking for more information that could aid for searching about understanding of the unit variety-complex. Nonhuman primates have been considered an important group among many studied animals having a great interest not only for t

4. Origem, trajeto, ramificaÃÃes e distribuiÃÃo dos ramos ventriculares da artÃria coronÃria direita no macaco prego (Cebus apella)
A Anatomia Comparativa de mamÃferos vem sendo tema de pesquisas nas Ãreas biomÃdicas e biolÃgicas com o objetivo de se buscar conhecimentos que possam contribuir na busca sobre o entendimento do binÃmio unidade-variedade. Os primatas nÃo humanos tÃm se constituÃdo em importante grupo dentre os animais submetidos a estudos diversos, o que se reveste d

5. Arterial vascularization of the papilares muscles of the left ventricle of the dog´s heart (Canis familiaris - L. 1758) / Vascularização arterial dos músculos papilares do ventrículo esquerdo de cães (Canis familiaris - L. 1758)
Cardiac irrigation, both in man and in other mammals, is a relevant subject that has been researched by several authors, among whom H. Rodrigues and his team, who have been seeking to subsidy the biomorphological base for myocardium vascular diseases. Information about the arterial vases related to papillary muscles is incomplete and scarce in the medical li

6. The developing atrioventricular bundle and its branches in relation to small induced ventricular septal defects in the heart of chick embryos.
The form and position of the developing atrioventricular bundle and its branches has been studied in the hearts of domestic fowl embryos operated upon to induce delayed closure of the interventricular foramen. The operation was performed at 3 days of incubation when the outflow tract of the tubular heart was temporarily distorted by placing a nylon rod benea

7. The development of the atrioventricular bundle and its branches in the avian heart.
A light microscopic study of serial sections of the hearts of 64 avian embryos (chicken, turkey, duck and goose) was undertaken in order to elucidate the development of the atrioventricular bundle and its branches. The developing atrioventricular bundle and its branches were shown to appear simultaneously (at about a third of the way through incubation) as r

8. Distribution of cardiac myosin isozymes in human conduction system. Immunohistochemical study using monoclonal antibodies.
To determine the presence and distribution of cardiac myosin isozymes in the human conduction system, we performed an immunohistochemical study using monoclonal antibodies CMA19 and HMC14, which are specific for myosin heavy chains of human atrial type (alpha-type) and ventricular type (beta-type), respectively. Serial frozen sections of human hearts were ob

9. The coronary circulation of the heart of the ostrich (Struthio camelus).
The distribution of the coronary arteries of the ostrich is described and compared with existing accounts of other species of birds. The blood supply to the ventricular walls, part of the interventricular septum and atria comes from the superficial branches of the left and right coronary arteries. The deep branches are small, supplying most of the interventr

10. Congenital absence of the pulmonary valve
The clinical, radiological, electrocardiographic, and haemodynamic findings in 7 patients with the syndrome of congenital absence of the pulmonary valve with ventricular septal defect are reported. Findings included a pansystolic murmur and a low-pitched delayed diastolic murmur at the left sternal border with no pulmonary valve closure sound, an rsR′ patt

11. The surgical anatomy of the conduction tissues.
On the basis of our collective experience we have reviewed the disposition of the cardiac conduction tissues as they might be observed by the surgeon in both normal and abnormal hearts. The sinus node lies subepicardially in the terminal sulcus; because of its variable blood supply the entire superior cavoatrial junction is a potential danger area. There are

12. Delay and block of cardiac impulse caused by enhanced phase-4 depolarization in the His-Purkinje system.
The underlying mechanism of bradycardia-dependent bundle-branch and paroxysmal atrioventricular block appears to be enhancement of phase-4 depolarization in a branch or in a natural or acquired monofascicular pathway. Clinical records of these forms of impaired conduction occurring in the bundle-branches, with either longer or shorter cardiac cycle lengths,
