A 13-year-old girl presented with clinical features of pulmonary stenosis and regurgitation. Haemodynamic studies suggested the presence of a right ventricular tumour. M-mode and two dimensional echocardiograms indicated one or probably two soft thin walled structures originating from the right atrium. At operation a persistent right sinus venosus valve was removed. One earlier case report desc...

ostium secundum type; sinus venosus type occurring high in the septum miear the orifice of the superior vena cava, commonly associated with anomabus pulmonary venous drainage; and ostium primum type which is frequently associated with a partial or complete cleft in the antero-medial leaflet of the mitral valve and possibly also in the medial cleft of the tricuspi(l valve. In our department, 75 ...

We report the case of an asymptomatic six-year-old child with left atrial isomerism and sinus venosus atrial septal defect. The physical examination revealed several periods of bradycardia. During a 24-hour electrocardiographic monitoring the patient presented a significant sinus node dysfunction with sinus pauses of up to 2.4 seconds. A permanent pacemaker was implanted, with a satisfactory ou...

The liver exerts its influence in general cellular metabolism and homeostatic control within limits set by the quality and quantity of blood perfusing it. Hepatic outflow reflects hepatic portal flow which is influenced by the diverse blood flow requirements of other visceral organs engaged in metabolic and absorptive functions. In addition, the hepatic blood flow constitutes a sizeable fractio...

BACKGROUND Concerns remain that minimally invasive atrial septal defect (ASD) repair may compromise patient outcomes. We compared clinical outcomes of adult patients undergoing ASD repair via a minimally invasive endoscopic approach versus a "gold standard" sternotomy. METHODS We retrospectively reviewed the clinical outcomes of consecutive patients who underwent ASD patch repair at our insti...

A reinforced cuffed endotracheal tube was used to drain blood from a left superior vena cava via the coronary sinus during patch repair of a sinus venosus defect in a 65 year old patient. This approach produced good drainage and a bloodless operative field.

Physiol. 45): H115–H128, 1999.—The effects of sympathetic nerve stimulation on beat rate, force, intracellular Ca21 concentration ([Ca]i) measured using fura 2, and membrane potential were recorded from the sponta...

In contrast with transthoracic echocardiography, transesophageal echocardiography provides a sure way to make the diagnosis of sinus venosus atrial septal defect; on the other hand this abnormality is more complex than that seen with the secundum atrial septal defect, and inexperienced operators may fail to recognize properly the defect. In front of a high reported sensitivity using transesopha...
