Isolated left-sided partial anomalous pulmonary venous connection with intact interatrial septum is a rare diagnosis in childhood. In these cases, a vertical vein drains the left upper pulmonary lobe into the brachiocephalic vein and finally to the right atrium. Surgical treatment is performed to prevent right ventricular failure and pulmonary artery disease in advanced age. In this report, the...

Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...

introduction low-grade endometrial stromal sarcoma (lg-ess) is a malignant intrauterine tumor that rarely presents with distant metastasis. simultaneous lung and cardiac metastases from lg-ess is also an extremely rare event. case presentation a 42-year-old woman presented with dyspnea and exercise intolerance. she had a history of hysterectomy and left salpingoophorectomy. she underwent second...

The total capacity of the heart and the volume of each of its chambers were determined by the technic of simultaneous biplane stereoscopic venous angiocardiography in 18 persons with surgically confirmed, isolated severe mitral stenosis. Although cardiac capacity and chamber volumes varied greatly, the left atrium was almost always the largest chamber. Time left ventricle was not always the sma...

A 76-year-old female presented with rheumatic mixed mitral valve pathology. A chest X-ray revealed massive cardiomegaly and splaying of the carina (Fig. 1). CT scan showed gross isolated left atrial (LA) enlargement (Fig. 2a), which was plicated from within (Fig. 2b). A mitral valve replacement and LA reduction was performed but she died of an operative complication. Fig. 1. Chest X-ray shows m...

Idiopathic dilatation of the right atrium (IDRA) is a rare anomaly defined as an isolated enlargement of the right atrium (RA) in the absence of other cardiac lesions or a condition cause RA dilatation. The clinical presentation ranging from asymptomatic to cardiac failure or even sudden death. It can be associated with atrial arrhythmias, thrombus formation and congestive heart failure. Antipl...

prolapsed mitral valve syndrome is a common, benign disorder with prevalence of %0.3-6 in population. this syndrome also is known as barlows syndrome and flaapy mitral valve syndrome. prolapsed mitral valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. this malformation leads to incomplete closing of mitral valve and regurgitates the bloo...

CHIBA, S. Potentiation of the Negative Chronotropic and Isotropic Effects of Adenosine by Dipyridamole. Tohoku J. exp. Med ., 1974, 114 (1), 45-48 The isolated right atrium of the dog was perfused with blood led from a support dog. The selective injection of dipyridamole into the sinus node artery at a dose of 1-10 ƒÊg induced a slight negative chronotropic and positive inotropic effect. The ad...

Supraventricular tachycardia in an isolated rabbit heart preparation was repeatedly initiated and terminated by carefully timed atrial premature beats. Transmembrane action potentials of AV nodal cells were recorded simultaneously by a "brush electrode" consisting of 10 microelectrodes. Surface electrograms of atrium and His bundle were also recorded. The moments of activation of 54 different A...
