Filter by:The primary aim of this study is to determine the optimal timing for repair of right-to-left shunt lesions such as Tetralogy of Fallot defects. The secondary aim being define the criteria for failing medical therapy.
The primary aim of this study is to determine the clinical and radiographic findings with constrictive pericarditis in the adult congenital population and determine the degree of right heart failure and dilation from pulmonary insufficiency in the presence of constrictive pericarditis The secondary aim is to elucidate ways to better diagnose constrictive pericarditis and elucidate ways to diagnose right heart failure in the presence of constrictive pericarditis.
The records of all the patients that underwent the Norwood-Sano operation at Children’s Healthcare of Atlanta, Emory University between January 1, 2002 and December 31, 2004 will be investigated. These patients will be compared with an equal number of consecutive cases treated by classic Norwood stage I operation in order to determine the incidence of neo-aortic valve insufficiency and the clinical outcome of these patients.
Infants with congenital long QT syndrome (LQTS) and 2:1 atrioventricular block (AVB) have been recognized as a clinical subset of children with LQTS. The purpose of this study is to describe the clinical course and outcome of a patient with congenital long QT syndrome (LQTS).
Clinical evidence reveals that some patients who undergo cardiac transplantation exhibit problems with pulmonary vascular resistance as well. In some studies, an increase in pulmonary vascular resistance has been used as an indicator for increased 3-day and 3-month mortality after heart transplantation2. In this study, the investigators would like to look at pulmonary vascular resistance in patients with a surgical history of the Fontan procedure followed by heart transplantation.
Collect data to support “standard of care possibility” of extracardiac repair with closure of intracavitary communication and plication of the aneurysm as probably safest surgical repair for left ventricular aneurysms.
The primary objective of this retrospective study of valve replacement is to document long-term survival and occurrence of valve related complications such as described in the literature; anticoagulant related bleeding event , thromboembolic events, subacute bacterial endocarditis (SBE), structural failure or deterioration , valve thrombosis, explantation and reimplantation with reason, death and death cause, and cerebrovascular accidents either permanent or transient in nature. Secondary to this is the presumption that mechanical valves have a superior “life expectancy “ to bio-prosthetic valves. We plan to look at the time of freedom from re-implantation from different types of valves, factoring in patient age, size ,defect and risk factors. The information learned from this study may benefit future patients who undergo the Ross procedure by increasing our knowledge of safer and/or more effective techniques.
The Ross procedure has become the surgery of choice for aortic valve replacement in children. This consists of taking a child's own pulmonary valve (the autograft) and replacing the child's diseased aortic valve with the autograft. At times, this can involve either enlarging or reducing the diameter of the aortic annulus to make the valve fit properly. The patient's own pulmonary valve is then replaced, most typically with a human heart valve (a homograft). There has been some concern in the literature that as time goes on, the autograft will dilate and the patient will develop progressive aortic insufficiency. Since 1994, we have performed almost 50 Ross procedures in children and young adults. Contrary to many reports from the literature, we have not recognized a problem with autograft enlargement and progressive aortic insufficiency. One thing that we have done differently from other centers is that we have modified the insertion technique of the autograft into the native aortic root. This involves a second buttressing suture layer. Not only does this have the immediate effect of reducing bleeding complications, we postulate that it has the long-term effect of stabilizing the autograft and preventing aortic root dilatation. We hypothesize that this proximal buttressing technique for the Ross procedure has a two-fold benefit. Firstly, it reduces the amount of bleeding in the postoperative period. Secondly, it prevents late autograft root dilatation.
A retrospective chart review will be performed on 50 patients who received RFA for the treatment of EAT between August 1992 and August 2003 at Children's Healthcare of Atlanta. The use of the CARTO/Biosense catheter has improved outcomes with decreased radiation exposure to patients.
The purpose of this study is to identify the patients seen in our practice who are seen with Hypertrophic Myopathy diagnosis in order to better understand the presenting characteristics of their disease, the diagnostic testing to determine the diagnosis, the methods used to follow the disease progression and management practices used in caring for these patients. The objectives of this data review will be an analysis to determine if there is a methodology that will foster improved diagnostic speed and accuracy, and determine the best management practices based on outcomes in these patients.
