as the rest of the fingers.5 Additionally, the thumb may be triphalanged, absent, or simply longer than normal in association with a short forearm which displays limited supination and pronation. All these upper extremity features are combined with an ostium secundum atrial septal defect, thereby completing the salient anatomy of the condition. The patient under current investigation did not ha...

We present a case of an atrial septal defect repair under cardiopulmonary bypass in a child with factor VII deficiency. A four-year-old girl, with the diagnosis of secundum atrial septal defect, was referred to surgery. Coagulation tests showed an international normalized ratio of 2.4. Further investigations revealed deficiency of factor VII with 42% activity. Fifteen minutes before the inducti...

Since the development of cardiac surgery, defects of the atrial septum have been recognized with increased frequency. During the past 15 years, various surgical techniques have been used, and even to-day the surgical treatment of this lesion is not uniform. In 1948, Murray first closed an atrial septal defect, suturing together the anterior and posterior atrial walls in the septal plane. S0nder...

Assessment of the complex relations between pressure and volume in the right atrium has been hampered in the past by difficulties in the measurement of atrial volume. Accordingly, in the present study the dynamics of right atrial pressure-volume relations were examined (with the use of an impedance catheter to measure right atrial volume) in patients with and without an atrial septal defect. Ri...

BACKGROUND AND OBJECTIVES This study aims to compare the characteristics, effectiveness and results of transcatheter closure of atrial septal defect between children, adolescents, and adults. SUBJECTS AND METHODS In this study, 683 patients who underwent atrial septal defect closure in the last 10 years were divided into three groups: children (age <12), adolescents (age 12 to 16), and adults...

L acerations or tears of the interatrial septum are a recognized complication of mitral valve replacement surgery; however, the first report of iatrogenic Lutembacher's syndrome was by Dr. John Ross Jr. and colleagues from the National Institutes of Health.1 Their series included three patients who had acquired mitral stenosis and developed a persistent atrial septal defect after transatrial se...

IN CONTRAST to cases of ventricular septal defect in which pulmonary arterial lesions occur at a very early age, such changes are generally considered to be late phenomena in atrial septal defect. It is well known that pulmonary hypertension, when it occurs as a complication of a defect in the atrial septum, is usually not seen before adult life.1' 2 The pulmonary arteries are reported to be la...
