We present a case of fetal-neonatal acute myocarditis caused by coxsackievirus B3 infection in a term neonate. The condition manifested as high-grade atrioventricular (A-V) block prenatally. After delivery, various arrhythmias such as high-grade A-V block, ventricular tachycardia, and junctional ectopic tachycardia appeared, and we had difficulty managing these arrhythmias. This is the first re...

Aorto-ventricular tunnel is a congenital, extracardiac channel which connects the ascending aorta above the sinutubular junction to the cavity of the left, or (less commonly) right ventricle. The exact incidence is unknown, estimates ranging from 0.5% of fetal cardiac malformations to less than 0.1% of congenitally malformed hearts in clinico-pathological series. Approximately 130 cases have be...

We quantitated the growth patterns of the normal fetal heart and the right and left ventricles from postmortem hearts obtained from 55 spontaneously aborted human fetuses from the completion of cardiogenesis to term. Fetal gestational age was assessed by menstrual history of the mother, crown-rump length, head circumference, and body weight and ranged from 8 to 40 weeks. Each heart was perfused...

introduction: pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. we have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. materials a...

OBJECTIVES The purpose of our work was to define the complex electrophysiological characteristics seen in second- (2 degrees) and third-degree (3 degrees) atrioventricular block (AVB) and to longitudinally follow the development of atrial and ventricular heart rate and rhythm patterns with a goal of identifying heart rate and rhythm patterns associated with urgent delivery or neonatal pacing. ...

It is unknown if nitric oxide (NO) influences the relative level of the left (LV) and right ventricular (RV) outputs, the blood flow distribution between the body and placenta, or whole body O2extraction and O2 consumption in the fetus. To address these questions eight fetal lambs were chronically instrumented at 128-134 days gestation (term 147 days), and blood flows were measured with radioac...

Most of the congenital heart diseases can be diagnosed in utero using fetal echocardiography. With the development of ultrasonography and intrauterine cardiac intervention technique, fetal cardiac intervention (FCI) for critical aortic stenosis, highly restrictive or intact atrial septum, pulmonary atresia with an intact ventricular septum (PA/ IVS), and critical pulmonary stenosis (CPS) are av...

      The ductus arteriosus (DA) is a vital structure in fetal circulation, carrying about two thirds of the right ventricular (RV) output to the aorta. During fetal life, ductal patency is actively preserved by several different factors, and pathologic ductal constriction causes right-sided pressure overload of the heart, leading to RV failure. There have been many reports of ductal constricti...

The cardiovascular effects of a new, long-acting, sympathomimetic amine, Aramine, are described. Cardiac output, aortic pressure, coronary flow, and ventricular stroke work rise while atrial pressures fall. A sustained increase in myocardial contractility is produced and the myocardium does not require more coronary flow per unit of ventricular work after its administration. The circulatory eff...
