Left Heart Volume Characteristics Following Ventricular Septal Defect Closure
نویسندگان
چکیده
Left ventricular and left atrial volume, left ventricular ejection fraction, and left ventricular muscle mass were determined preoperatively and postoperatively in 13 patients who underwent surgical closure of ventricular septal defects in the first two years of life. Left ventricular end-diastolic volume and systolic output averaged 255 ± 19% (± SEM) and 240 ± 19% of normal, respectively, before operation but fell to within normal limits postoperatively. Left ventricular ejection fraction was normal preoperatively (100 ± 4% of

Left heart volume characteristics following ventricular septal defect closure in infancy.
Left ventricular and left atrial volume, left ventricular ejection fraction, and left ventricular muscle mass were determined preoperatively and postoperatively in 13 patients who underwent surgical closure of ventricular septal defects in the first two years of life. Left ventricular end-diastolic volume and systolic output averaged 255 +/- 19% (+/- SEM) and 240 +/- 19% of normal, respectively...

متن کاملTiming in resolution of left heart dilation according to the degree of mitral regurgitation in children with ventricular septal defect after surgical closure.
OBJECTIVE Children with ventricular septal defects (VSD) can have chronic volume overload, which can result in changes of left heart echocardiographic parameters. To evaluate the changes before and after surgical closure, the children were divided into three groups according to the degree of mitral regurgitation (MR), and their echocardiographic characteristics were reviewed at serial follow-up...
متن کاملInteratrial-pressure relationships after closure of atrial septal defects in man.
RECENTLY Watkins and Gross' described a clinical syndrome that followed surgical closure of atrial septal defects in some of their patients. This syndrome consisted of the retention of fluid and a gain in weight during the early postoperative period. At times there followed tenderness in the right upper quadrant of the abdomen, hepatomegaly, and roentgenographic evidence of pulmonary congestion...
متن کاملTranscatheter closure of a residual postmyocardial infarction ventricular septal defect with the Amplatzer septal occluder.
Acute ventricular septal rupture following myocardial infarction carries a high mortality. Early surgery improves survival but long term outcome depends on residual shunting and left ventricular function. Residual shunting is common despite apparently successful closure and may require reoperation. Transcatheter closure is an established method of treating selected congenital defects but clinic...
