Dextrocardia with situs solitus and inversion apex-basis axis in lesser anteater (Tamandua tetradactyla): case report

Dextrocardia is a rare cardiac anomaly where the heart is situated on the right antimeres of the thorax. This study had the objective of describing a case of dextrocardia with situs solitus and apex-basis axis inversion in a lesser anteater (Tamandua tetradactyla) between five evaluated animals, all from the area of Mine Bauxite - Paragominas - Para. The arterial system was filled with contrasted latex and the animals were fixed with 10% formaldehyde and a posterior dissection was done. The heart of an animal was found in right antimere with inversion of the base-apex axis. The right atrium was more developed then the left and the pulmonary veins arrived directly in the left ventricle. The main vases of the base were identified with some topographic alterations resulting in: aorta dorsal to the cava caudal vein, pulmonary artery dorsal and cranial to aorta, pulmonary veins ventral to the pulmonary artery, cava caudal vein in ventral plain and cava cranial vein in dorsal plan in relation to the other vessels. Internally there were four cardiac chambers, with absence of septal communication.

ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory insufficiency and whose clinical examinations revealed a giant tumor mass extending from the right ventricle to the pulmonary artery. We discuss the diagnostic and therapeutic options. CONCLUSION: In patients presenting with acute right heart failure, right ventricular masses should be kept in mind. Transthoracic echocardiography appears to be the most easily available, noninvasive, cost-effective and useful technique in making the differential diagnosis.

SummaryCor triatriatum sinister is a rare congenital cardiac anomaly that has been identified in 0.1% of children with congenital heart disease. It is defined as a fibromuscular membrane that divides the left atrium into two chambers: a superior (proximal) that in most cases receives drainage from the pulmonary veins and an inferior (distal) chamber that communicates with the mitral valve and the left atrium. Cor triatriatum sinister can be an isolated lesion (approximately 25% of cases), but in many cases it is associated with other congenital cardiovascular anomalies, the most common one being – atrial septal defect(3). Symptoms in patients with cor triatriatum sinister are related to obstruction of pulmonary venous drainage, pressure loading of the right side of the heart and congestive cardiac failure. Depending on the severity of the obstruction and presence of associated cardiac anomalies it can be diagnosed at any age. Diagnosis is usually achieved by echocardiography in early infancy. Elective treatment method is surgical excision of the membrane. Here we present a pediatric patient (4 months old) presenting in cardiogenic shock with a successful correction of isolated cor triatriatum sinister. To confirm diagnosis and success of surgical repair, transthoracic and transesophageal echocardiography were used.

Heart Lesions

The diagnosis of pulmonary hypertension (PH) requires a right heart catheterization (RHC) that reveals a mean pulmonary artery pressure ≥ 25 mmHg. The pulmonary artery catheter traverse the right atrium and ventricle on its way to the pulmonary artery. The presence of abnormal right heart structures, i.e. thrombus, vegetation, benign or malignant cardiac lesions, can lead to complications during this procedure. On the other hand, avoidance of RHC delays the diagnosis and treatment of PH, an approach that might be associated with worse outcomes. This paper discusses the impact of right heart lesions on the diagnosis of PH and suggests an approach on how to manage this association.

New methods for chronic instrumentation of the newborn piglet are described, which allow continuous monitoring of not only pressures in the pulmonary artery and aorta but also in the left and right atria, pulmonary vein, as well as main branch pulmonary artery flows. Changes in pulmonary vascular tone to short-acting vasoactive agents can be recognized by redistribution of flow between lungs and localized to the precapillary vessels or pulmonary veins. Furthermore, vasoactive response in small pulmonary veins may be investigated as well as selective metabolic studies across the right lung. Methods are also described for the chronic cannulation of the neck vessels permitting repeated introduction of catheters on separate study days in the conscious piglet. The pulmonary circulation of the piglet constricts briskly to moderate hypoxemia ([Formula: see text], 1 Torr = 133.32 Pa) with little change in cardiac output or systemic resistance. The piglet demonstrated responses to dilator and constrictor prostaglandins generally similar to the lambs and other species. None of these agents significantly affect pulmonary venous tone.
