OBJECTIVE To discuss the anatomical features of sinus venosus atrial defect on the basis of a comprehensive transoesophageal echocardiography (TOE) examination and its relation to surgical data. METHODS 24 patients (13 men, 11 women, mean (SD) age 37 (17) years, range 17-73 years) with a posterior interatrial communication closely related to the entrance of the superior (SVC) or inferior vena...

Intrinsic regulation of the heart in teleosts is partly driven by central venous pressure, which exerts a modulatory role on stroke volume according to the well-known Frank-Starling mechanism. Although this mechanism is well understood from heart perfusion studies, less is known about how this mechanism operates in vivo, where heart rate varies markedly. We used zatebradine, a bradycardic agent...

INTRODUCTION Anterior mini-thoracotomy approach is a good alternative to median sternotomy in Atrial Septal Defect (ASD) repair. Our purpose is to explain the details of our technique and peresent the results. METHODS Seventy five patients with ASD (52 female and 23 male) were operated with anterior mini-thoracotomy approach in our tertiary center between March 2012 and March 2014. The mean a...

A69-year-old diabetic man without previous cardiac history was admitted for stabilization of glycemic control. A routine ECG showed atrial fibrillation with right bundlebranch block, and the chest radiograph revealed marked prominence of the central pulmonary arteries. Accordingly, transthoracic echocardiography was performed, which demonstrated an atrial septal defect with moderate pulmonary h...

Background: Partial anomalous pulmonary venous connection (PAPVC) is frequently associated with atrial septal defect (ASD), especially sinus venosus (SVD). Although Waggstaffe described the pathology of SVDs in 1868, exact anatomic features and nature SVD remains controversial. no posterior rim were observed recent years. However, studies suggested that absence residual tissue might be key feat...

Exchange transfusion in small infants carries a mortality of 4-7 5% (Van Praagh, 1961; Boggs and Westphal, 1960). Many factors such as hypocalcaemia, circulatory overloading, hyperkalaemia, acidosis, citrate toxicity may be responsible, and the mode of death, whatever the aetiology, is usually thought to be acute cardiac failure (O'Neill and Gordon, 1959; Robinson and Barrie, 1963), and commonl...
