Pulsus paradoxus in a patient with tricuspid atresia and hypoplastic right heart.
نویسندگان
چکیده
Increased inspiratory right ventricular filling with a consequent shift of the ventricular septum to the left, thereby decreasing left ventricular filling, has been suggested as a mechanism of pulsus paradoxus. We recently saw a patient with tricuspid atresia and hypoplastic right ventricle who developed pulsus paradoxus. His course may help clarify the contribution of this mechanism.

CASE REPORT Pulsus Paradoxus in a Patient with Tricuspid Atresia and Hypoplastic Right Heart
SEVERAL MECHANISMS have been proposed to account for the exaggerated fall in systolic blood pressure that occurs with cardiac tamponade (pulsus paradoxus).' These include a fall in venous return to the left atrium caused by a decrease in the pressure gradient between pulmonary veins and left atrium during inspiration;2-6 inspiratory traction on the pericardium limiting diastolic filling;68 incr...
متن کاملHolt-Oram Syndrome: A Rare Variant
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 کاملEffect of respiration on venous return and stroke volume in cardiac tamponade.
Measurements have been made of pressure and blood velocity in venae cavae and aorta in a patient with severe cardiac tamponade in whom there was pulsus paradoxus. The characteristic pressure changes of pulsus paradoxus were associated with variations in peak blood velocity in the ascending aorta and stroke output. Maximum filling of the right side of the heart occurred during inspiration, and w...

SUMMARY Echocardiographic studies were performed on six patients with autopsy-proved aortic atresia and hypoplastic left ventricle and two patients with surgically proved tricuspid atresia and hypoplastic right ventricle. The findings were compared to those from the echograms of 50 normal newborns who served as a control group. The ultrasound measurements obtained in the normal newborns were as...
