Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart. Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale ; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
The ULTRASEAL LAA device, from Cardia, is a percutaneous, transcatheter device intended to prevent thrombus embolization from the left atrial appendage in patients who have non-valvular atrial fibrillation. As with all Cardia devices (such as: Atrial Septal Defect Closure Device or Patent Foramen Ovale Closure Device), the Ultraseal is fully ...
The ostium primum atrial septal defect is a defect in the atrial septum at the level of the tricuspid and mitral valves. This is sometimes known as an endocardial cushion defect because it often involves the endocardial cushion, which is the portion of the heart where the atrial septum meets the ventricular septum and the mitral valve meets the tricuspid valve.
Surgical mortality for uncomplicated ostium primum defects in experienced centers is 2%; for uncomplicated cases of complete atrioventricular canal defect, 4% or less. Certain complications such as tetralogy of Fallot or highly unbalanced flow across the common AV valve can increase risk significantly. [13] [14]
A sinus venosus atrial septal defect is a type of atrial septal defect primarily associated with the sinus venosus. They represent 5% of atrial septal defects. [1] They can occur near the superior vena cava or inferior vena cava, but the former are more common. [2] They can be associated with anomalous pulmonary venous connection. [3]
Among them was an open repair of an atrial septal defect using hypothermia, inflow occlusion and direct vision in a 5-year-old child performed in 1952 by Lewis and Tauffe. C. Walter Lillihei used cross-circulation between a boy and his father to maintain perfusion while performing a direct repair of a ventricular septal defect in a 4-year-old ...
Fredrick Arthur Willius (1888–1972), founder of the cardiology department at the Mayo Clinic and an early pioneer of electrocardiography; Louis Wolff (1898–1972), known for Wolff–Parkinson–White syndrome; Karel Frederik Wenckebach (1864–1940), first described what is now called type I second-degree atrioventricular block in 1898
Heart sounds of a ventricular septal defect patient. The condition consists of atresia affecting the pulmonary valve and a hypoplastic right ventricular outflow tract. The ventricular septal defect doesn't impede the in and outflowing of blood in the ventricular septum, which helps it form during fetal life.
