OBJECTIVES Intracardiac thrombus formation is suspected to be a specific sequela after the Fontan operation and is difficult to determine by means of routine transthoracic echocardiography. The aim of our study was to evaluate the occurrence of intracardiac thrombi in the different types of Fontan modifications and to identify predisposing risk factors. (More)
Intense exercise has been shown to have negative effects on systolic and diastolic ventricular function in adults. Very little is known about the normal reaction of the growing heart to endurance stress. For this study, 26 healthy children (18 males) with a mean age of 12.61 years (range, 7.92–16.42 years) took part in an age-adapted triathlon circuit. The(More)
BACKGROUND AND METHODS There are few data on the prevalence and clinical outcome of hepatitis C infection in children. We studied 458 children who underwent cardiac surgery in Munich, Germany, before 1991, when blood-donor screening for hepatitis C was introduced in Germany. Their mean age at first operation was 2.8 years; none of the children had received(More)
BACKGROUND Survival and functional status of patients with transposition of the great arteries treated by atrial switch are reported to be reasonably good within the first 15 postoperative years. However, in some patients, the function of the systemic right ventricle deteriorates, leading to significant morbidity or even to late mortality. This study seeks(More)
BACKGROUND Despite successful surgical correction, morbidity of patients with coarctation of the aorta is increased. It is well known that these patients have impaired elastic properties of the prestenotic arteries. To find out whether these abnormalities are primarily present or develop later, we studied 17 newborns before and early after surgical repair.(More)
OBJECTIVE To evaluate the influence of volume unloading by bidirectional superior cavopulmonary anastomosis on the systemic right ventricle in patients with hypoplastic left heart syndrome. METHODS A total of 90 consecutive patients with hypoplastic left heart syndrome, who had survived the early postoperative period after bidirectional superior(More)
OBJECTIVE To compare survival, freedom from reoperation, and functional status between atrial switch and arterial switch operations for transposition of the great arteries. METHODS Data from 88, 329, and 512 patients who underwent Mustard, Senning, and arterial switch operations between 1974 and 2006 were analyzed. RESULTS In-hospital mortalities were(More)
BACKGROUND The study was conducted to assess the need for fenestration for completion of a total cavopulmonary connection (TCPC) with the most recent modification of an extracardiac conduit. METHODS The extracardiac approach was introduced to our institution in January 1999. Between June 2000 and June 2006, 132 consecutive patients were treated without a(More)
Acute myocardial infarction (MI) is a life-threatening condition rarely encountered in neonates. The patients usually present with sudden cardiogenic shock. Clinical management in neonates is extremely challenging. If treatment is delayed, the prognosis is dismal. We report on a 4-day-old full-term male newborn presenting with acute MI and cardiogenic shock(More)
A modified Fontan operation (Fontan Björk [Bjork VO, Olin CL, Bjarke BB, Thoren CA. Right atrial-right ventricular anastomosis for correction of tricuspid atresia. J Thorac Cardiovasc Surg 1979;77:452--8]) for absent right atrio-ventricular connection was done by using a homograft between the right atrium and the right ventricle in some patients. We present(More)
