We describe a case of double outlet right ventricle with subaortic ventricular septal defect and pulmonary stenosis treated successfully with cardiopulmonary bypass. We consider the clinical history and angiocardiographic and surgical findings of this rare anomaly. We stress the difficulties of reconstruction of the outflow tract of the right ventricle, because of the anomalous pathway of the r...

We investigated how pacing from different endocardial sites affects the left ventricular three-dimensional contraction pattern and performance in intact anesthetized dogs. We used data from the motion of radiopaque markers implanted in the left ventricular endocardium in an analysis based on the polar decomposition theorem to determine the left ventricle's three-dimensional principal directions...

Sixty-two hearts without a patent exit from the left atrium to the ventricular mass have been studied. All had situs solitus and laevocardia. The material consisted of 32 cases with coexistent aortic atresia and 30 cases with patent aortic root. Five hearts with aortic atresia were biventricular with atrioventricular concordance and imperforate left atrioventricular valves, and 27 hearts were u...

In 1616, Sir William Harvey was the first to describe the importance of right ventricular (RV) function in his seminal treatise, De Motu Cordis: “Thus the right ventricle may be said to be made for the sake of transmitting blood through the lungs, not for nourishing them.”1,2 For many years that followed, emphasis in cardiology was placed on left ventricular (LV) physiology, overshadowing the s...

BackgroundIncreased metabolic rate of hyperglycemia in gestational diabetes causes macrosomia, which can also affect the fetal heart. The thickness of the walls of the heart and its function in women with gestational diabetes mellitus (GDM) can change over time before treatment. We aimed to evaluate fetal cardiac structure in terms of ventricular wall thickness and its function in women w...

We report the case of a rare complex cardiac anomaly involving situs solitus, concordant atrioventricular connection with left-hand ventricular topology, and L-looped ventricles. The ventricles had superior-inferior relationship an inferiorly located right ventricle, which double outlet far posteriorly great arteries. left atrium was elongated, juxta-positioned atrial appendages on side. 3D-pri...

We report a rare case of neonatal biventricular repair of a right interrupted aortic arch (type B), with an aberrant left subclavian artery, ventricular septal defect and retroaortic innominate vein in a 4-week-old, 2.7 kg neonate with DiGeorge syndrome. The patient had an unremarkable postoperative recovery. We discuss the anatomy of this rare congenital anomaly, its surgical implications and ...

A major coronary artery crossing the right ventricular outflow tract in patients with tetralogy of Fallot interferes with a transannular patch, and preoperative detection of this artery is important. We evaluated the ability of two-dimensional echocardiography to define noninvasively the coronary artery anatomy in 37 consecutive patients (age range, 1 day to 18 years; mean age, 40.9 months). Th...

Right ventricular loading/pressure influences left ventricular function because the two ventricles pump in series and because they are anatomically arranged in parallel, sharing the common ventricular septum. Flattening of the interventricular septum detected during echocardiographic examination is called D-shaped left ventricle. We present a case of an elderly male of African descent, who pres...
