First Heart Sound in Atrial Septal Defect
Angiology, 1981This is a retrospective study of 25 patients with secundum-type of ASD, confirmed by catheterization and angiocardiography. As controls, 25 normal subjects of matching age were studied. The phonocardiograms and carotid pulses of the 2 groups were recorded and compared. Special attention was paid to the interval between the 2 main components (Ia and Ib)

The second heart sound in atrial septal defect
The American Journal of Cardiology, 1971Abstract Ventricular and arterial pressure tracings, electrocardiograms and phonocardiograms were studied in 4 normal subjects and 52 patients with atrial septal defect. After excluding cases in which complicating factors were involved, 10 cases of secundum type and 3 cases of primum type were studied in detail.

The first heart sound in atrial septal defect
American Heart Journal, 1969Abstract An electrocardiographic, phonocardiographic, and right-sided cardiovascular pressure study was made in 18 cases of atrial septal defect. The study was primarily concerned with the various components (a, b, and c) of the first heart sound (I) and their relationship to the dynamic events of the right heart. The following facts were ascertained.

Heart Rate Behavior in Children with Atrial Septal Defect
Cardiology, 1998The aim of this study was to assess heart rate variability, a noninvasive parameter for studying the neurohumoral control of heart rate, in children with atrial septal defect. We examined five time-domain and three frequency-domain indices of heart rate variability determined from 24-hour Holter recordings in 20 children, aged 3–14 years, with secundum

Open heart closure of an atrial septal defect by use of an atrial septal occluder in a dog
Journal of the American Veterinary Medical Association, 2010Abstract Case Description—A 3-year-old sexually intact male Standard Poodle was admitted to the veterinary teaching hospital for transcatheter closure of a large atrial septal defect (ASD). Clinical Findings—The dog had exercise intolerance and was thin.

"Left Heart Failure" and Atrial Septal Defects.
Annals of Internal Medicine, 1965Excerpt Complete clinical, laboratory, and repeated hemodynamic studies were carried out on 38 cases of large atrial septal defect of the secundum type ranging in age from 1 to 71 (mean, 38.6 years...

Normal splitting of the second heart sound in atrial septal defect∗
The American Journal of Cardiology, 1967Abstract A case is presented of a patient with proved ostium secundum atrial septal defect and a large left to right shunt without associated anomalous pulmonary venous return or pulmonary hypertension who demonstrated a second heart sound that was widely split with inspiration and became single with expiration.

Development of an Endocardioscope for Repair of an Atrial Septal Defect in the Beating Heart
ASAIO Journal, 1999The purpose of this study was to evaluate the possibility of surgical treatment of an atrial septal defect in the beating heart without cardiopulmonary bypass. The first step was to develop an endocardioscope that permitted observation of the inside of the beating heart. To visualize the inside of the beating heart, the tip of the endoscope was covered

Lung function in atrial septal defect after heart surgery
International Journal of Cardiology, 1992Lung volume, indices of lung elasticity and airway patency were measured in 74 patients, 9-21 yr old (15.0 +/- 2.5 yr) with atrial septal defect (secundum type) from 2-11 (5.1 +/- 2.5) yr after successful surgical correction. Clinical condition in all patients was classified as excellent.

Novel Imaging of Atrial Septal Defects in Isolated Human Hearts
Journal of Cardiovascular Translational Research, 2013Within the adult population living with congenital heart defects, approximately 20 % have an atrial septal defect, which suggests that only 0.4-0.05 % of the entire adult population has an atrial septal defect (ASD). In patients with a left to right atrial shunt, treatments may include closure of the defect with a transcatheter device and/or surgical ...
