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.

Repair of postinfarction ventricular septal defect on a beating heart [PDF]
The Annals of Thoracic Surgery, 1996 Two elderly patients with postinfarction ventricular septal defect underwent repair by endocardial patch with infarct exclusion on a beating heart under normothermic cardiopulmonary bypass with ultra-short-acting beta-blocker infusion. Their hemodynamic states soon recovered, and postoperative angiographic studies showed improvement of cardiac function

Recatheterization of the right heart in ventricular septal defect
American Heart Journal, 1959Abstract Repeat right heart catheterization was carried out in 20 patients from 17 months to 9 years following the initial study. In only a few patients was there an increase in pulmonary pressure. In some infants there was a significant fall. No deterioration in clinical signs or symptoms occurred. In view of these data it is suggested that one be

Traumatic interventricular septal defect of heart a case report
American Heart Journal, 1962Abstract An acquired interventricular septal defect of the heart resulted from a nonpenetrating traumatic cardiac injury sustained by the driver in an automobile accident. The defect developed 10 days after the accident, when intractable cardiac failure began and continued until death, 28 days later.

Nature of heart failure in patients with ventricular septal defect
American Journal of Physiology-Heart and Circulatory Physiology, 1995To assess the contributions of systolic and diastolic dysfunction to congestive heart failure (CHF) in ventricular septal defect (VSD), we studied 13 children with VSD at catheterization using a Millar catheter. Eight children had CHF, whereas five did not. Phenylephrine was infused at a rate of 5 micrograms.kg-1.min-1, and M-mode echocardiography and

"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...

Design of heart phantoms for ultrasound imaging of ventricular septal defects
International Journal of Computer Assisted Radiology and Surgery, 2021Ventricular septal defects (VSDs) are common congenital heart malformations. Echocardiography used during VSD hybrid cardiac procedures requires extensive training for image acquisition and interpretation. Cardiac surgery simulators with heart phantoms have shown usefulness for such training, but they are limited in visualization and characterization ...

The Conduction System in Cattle Hearts with Ventricular Septal Defects
Anatomia, Histologia, Embryologia, 1983AbstractAn anatomical study of abattoir acquired bovine hearts with ventricular septal defects was carried out. Hearts were fixed and stored in 4% formalin solution with heart dissection used for gross anatomical location of the conduction system of the ventricles.

Pediatrics, 1960
Seventeen patients had a history of congestive heart failure in infancy out of a total of 125 cases of ventricular septal defect reviewed. The initial episode of cardiac decompensation occurred in the first 6 months of life. Ten of the patients had evidence of unremitting failure and died in the first year of life, while seven survived infancy ...

Congenital Heart Disease: Atrioventricular Septal Defects
2017Atrioventricular canal defects (AVC) constitute 4–5% of congenital heart disease. AVC are a spectrum of malformations, characterized by a defect in the atrial septum, a defect in the ventricular septum and a defect in one or both atrioventricular (AV) valves.
