Peripheral blood flow in secundum-type atrial septal defect; preoperative and postoperative studies.
The purpose of this study was to correlate intracardiac shunt and peripheral blood flow measured by a venous-occlusion plethysmograph in 30 patients with secundum-type atrial septal defects. Preoperative and postoperative blood flows in the forearm were expressed as milliliters per minute per 100 gm of tissue. Peripheral flow increased after closure of the atrial septal defect, except in seven ...
متن کاملSome immediate hemodynamic consequences of closure of atrial septal defects of the secundum type.
The circumclusion method for surgical closure of atrial septal defects (ASDs) of the secundum type makes it possible, during surgery, to close and reopen the defect as desired. In each of 23 patients the following statistically significant pressure and flow changes were found when the ASD was closed: increasing mean pressures in the ascending aorta (from 74 to 87 mm Hg), left atrium (from 10 to...

متن کاملPrevalence of Secundum Atrial Septal Defect and Associated Findings
The goal of this chapter is to review data regarding the current prevalence estimates for secundum type atrial septal defect (ASD) and to give the reader a sense as to how these prevalence data compare relative to other common cardiac defects. This chapter will also review the current understanding of cardiac and non-cardiac findings known to be associated with secundum ASD. It is recognized th...
