A 31-yr-old female patient previously diagnosed with idiopathic pulmonary arterial hypertension (PAH) was referred to our centre for further evaluation. Cardiac magnetic resonance imaging (MRI) and echocardiography revealed a superior sinus venosus atrial septal defect (ASD) with partial anomalous pulmonary venous drainage. Following re-diagnosis, surgical repair was considered. Despite a dispr...
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.
Bramich, Narelle J., and Helen M. Cousins. Effects of sympathetic nerve stimulation on membrane potential, [Ca]i, and force in the toad sinus venosus. Am. J. Physiol. 276 (Heart Circ. 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...
The most common defects in the atrial septum are ostium secundum, ostium primum and sinus venosus atrial septal defects (ASDs) and patent foramen ovale. The management of ostium primum and sinus venosus defects is by surgery because of associated abnormalities, namely, cleft in the mitral valve causing mitral regurgitation in ostium primum defects and partial anomalous pulmonary venous connecti...
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...
BACKGROUND Identifying molecular pathways regulating the development of pacemaking and coordinated heartbeat is crucial for a comprehensive mechanistic understanding of arrhythmia-related diseases. Elucidation of these pathways has been complicated mainly by an insufficient definition of the developmental structures involved in these processes and the unavailability of animal models specificall...
The Wolff-Parkinson-White syndrome (WPW) and sinus venosus atrial septal defect (ASD) association is very rare and not yet reported in the literature. It is the main basis for this case report.
Anatomic variants of the remnants of the right valve of the sinus venosus in adults are common and usually observed on cardiac imaging studies. Because the anatomy and function of these vestiges are not well known, errors may occur in the differential diagnosis and treatment of patients with unclear images in the right atrium. Clinical implications may arise from (1) differential diagnosis with...
