The impact of anatomical subgroups for regional and global function of the right ventricle in hypoplastic left heart syndrome
نویسندگان
چکیده
Methods 36 children (5.8 ± 2.4 yrs) with HLHS after completion of Fontan-circulation were investigated. 17 patients (pts) had mitral and aortic atresia (MA/AA) without a visible left ventricular cavity. In 19 pts representing the anatomical subgroups mitral stenosis/aortic atresia (MS/AA) and mitral stenosis/aortic stenosis (MS/AS) a left ventricular cavity was present. We used CMR cine-imaging (TR/TE/a = 1.1/1.6/60, FOV: 240x260) for analysis of global (EF, and cardiac index-CI) and regional ventricular function. For analysis of regional (wall thickening, wall motion) ventricular function, each myocardial slice of the RV was divided into 4 anatomic segments to quantify wall thickening (%) and wall motion (mm).

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic...
متن کاملGlobal improvement in right ventricular function after Stage II Norwood operation in children with hypoplastic left heart assessed by serial MRI
Introduction Hypoplastic left heart syndrome (HLHS) describes a spectrum of left heart hypoplasias, which leave the left ventricle unable to support the systemic circulation. Staged palliation consists of aortic reconstruction and systemic to pulmonary artery shunt in the neonatal period (stage I), followed at intervals by superior (Stage II) and then total cavopulmonary connection (Stage III)....

A 5-year-old girl was admitted to the hospital with chest pain, fever and dyspnea. Physical examination showed normal heart sounds, diminished pulmonary sounds in the left hemithorax and a normal ECG. On chest X-ray the heart was slightly enlarged with moderate left pleural effusion. CT scan revealed pleural effusion and a hypodense mass at the apex of the heart. A cystic mass was detected...
