Cardiac myxomas are the most common neoplasms of the heart. They can be located in any chamber of the heart but frequently in the left atrium. In this report we present a patient who had been treated for a right ventricular myxoma originating from the interventricular septum and leading to right ventricular outflow tract obstruction.
A12-year-old previously healthy girl developed syncope when walking at school. When she was seen in the emergency department, her heart rate was 115 bpm, the precordial impulse was active, and a thrill was palpated. Third and fourth heart sounds were heard. A grade 4/6 systolic ejection murmur was heard at the left upper sternal border. The chest x-ray demonstrated a mildly enlarged, globular h...
OBJECTIVE Acute pulmonary hypertension may cause right ventricular (RV) contractile failure. While it has been assumed that restoration of normal loading conditions after acute pulmonary hypertension is sufficient for complete recovery of RV function, this has not been rigorously examined. The purpose of this study was to test the hypothesis that acute RV pressure overload produces RV contracti...
Background: The right ventricle to pulmonary artery conduit (RVPAC) may impair ventricular (RV) function in patients with functional single ventricles. Modification of the RVPAC using a ring-reinforced end dunked insertion into RV through limited ventriculotomy reduce impact on function. We compared segmental strain between traditional and feature tracking cardiovascular magnetic resonance (CMR...
Background: Nowadays, the treatment of choice for anatomical correction of transposition of great arteries is arterial switch but some children are not good candidates for this operation. In these cases atrial switch or Senning procedure is an accepted method, thus outcome of this procedure needs to be better delineated. Methods: This prospective study included 65 patients that underwent Senni...
