further investigation and re-evaluation found him to be anemic secondary to intravascular hemolysis . cardiac catheterization showed residual shunting through the vsd device margins causing the hemolysis. although this is a rare complication of vsd device closure, the patient's initial presentation of he...
Cardiac output, pulmonary artery pressures, the orifice area of valves, and the degree of left-to-right shunting can be determined.Angiocardiography is the x-ray examination of the heart after injection of a radiopaque contrast medium through a catheter at various locations in the heart. The ...
heart transplantation (HTx) has evolved from its experimental stage to an established treatment option for patients in end-stage heart failure [1–3]. In 1967, the allograft survived six hours. Only with the introduction of cyclosporine, further pediatric transplants followed in the 1980’...
The systolic blood pressure response to exercise may also be lower, owing to a decrease in peripheral vascular resistance created by less shunting of blood from visceral capillary beds to supply working muscle. The reduced myocardial Vo2 at submaximal loads explains the effectiveness of properly ...
The incidence of foramen ovale restriction or closure is greater in fetuses with congenital heart defects (CHDs) and obligate atrial shunting and/or left a... MT Donofrio,YA Bremer,WB Moskowitz - 《American Journal of Cardiology》 被引量: 44发表: 2004年 The evolving management of adult congen...
The device can be attached to a delivery hub. The wires forming the occluder region and securing region can have a shape-memory capability such that they can be collapsed and distorted in a sheath during delivery, but resume and maintain their intended shape after delivery....
implantation in small adults and children. In recent years, research has focused on continuous flow systems as an alternative to the traditional pulsatile model. In a continuous flow system, blood is continuously pumped through the body rather than pulsing the blood rhythmically as in the human ...
both in terms of aeration and in terms of thepulmonary vascular pressure. Optimization of lung recruitment and addressing raisedPVRare both important strategies to improveRVfunction. Judicious management of the shunting through thePDAmay also be important with strategies to allow the PDA to remain ope...
In subject area: Pharmacology, Toxicology and Pharmaceutical Science Congenital heart defects are structural problems that result from abnormal formation of the heart or major blood vessels that arise from the heart. From: Handbook of Clinical Neurology, 2021 Featured on this page...
