In recent decades, significant progress has been made in the diagnosis and management of congenitally corrected transposition of the great arteries (ccTGA). Nevertheless, gradual dysfunction and failure of the right ventricle (RV) in the systemic circulation remain the main contributors to mortality and disability for patients with ccTGA, especially after adolescence. Anatomic repair of ccTGA effectively resolves the problem of failure of the systemic RV and has good early and midterm results. However, this strategy is applicable primarily in infants and children up to their teens and has associated risks and limitations, and new challenges can arise in the late postoperative period...

OBJECTIVE: During recent years several changes have occurred in the clinical characteristics of infective endocarditis (IE) which has made a new challenge in the management of this disease. This study aimed to understand current practice pattern in the management of pediatric IE in China. METHODS: This retrospective, multicenter study was conducted in 13 hospitals. Clinical data of 268 patients diagnosed as IE according to the new IE criteria (trial) between 2000 and 2006 were analysed, focusing particularly on management and outcome of patients...

BACKGROUND: The incidence of rheumatic heart disease (RHD) has increased recently in the western United States. We reviewed our 18-year surgical experience with RHD in children to examine current surgical techniques and results. METHODS: From 1985 until 2003, 596 children (<21 years) with rheumatic fever were seen at Primary Children's Medical Center. Rheumatic carditis was diagnosed in 366 patients (61.4%). Twenty-six with carditis (26/366, 7.1%) required operation for rheumatic valve disease including 8 for mitral regurgitation, 7 for mitral and aortic regurgitation, 4 for aortic regurgitation, 4 for mitral regurgitation and stenosis, 2 for combined mitral stenosis and regurgitation with aortic insufficiency, and 1 for mitral and tricuspid regurgitation...

BACKGROUND: Prosthesis survival, growth, and functional status after initial mechanical mitral valve replacement (MVR) in children <5 years of age are poorly defined. METHODS AND RESULTS: The experience of the Pediatric Cardiac Care Consortium (45 centers, 1982 to 1999), which included 102 survivors after initial MVR, was analyzed. Median follow-up: 6.0 years (interquartile range: 3.0 to 10.6 years; 96% complete). Twenty-nine survivors had undergone a second MVR at an interval of 4...

Ebstein's anomaly of the tricuspid valve is characterized by a regurgitant tricuspid valve with a large anterior leaflet and septal and tricuspid leaflets displaced into the right ventricle. Associated anomalies are common, especially atrial septal communication and right ventricular outflow tract obstruction. Clinical presentation includes a spectrum from minimal hemodynamic derangement and mild exercise intolerance to severe cardiopulmonary abnormalities and grave illness. The natural history of the disease is extremely variable; the worst prognosis is in the youngest patients, who often have associated cardiac abnormalities...

Over the last three decades, management of truncus arteriosus has evolved with improving outcomes. Surgical repair is currently performed primarily during the neonatal period. This has prevented the severe morbidity and mortality resulting from congestive heart failure and pulmonary vascular obstructive disease. Although it has been 30 years since successful surgical repair of this lesion, the long-term follow-up studies have been limited to children who underwent truncus repair beyond the infancy period. In this article, we review the literature and also summarize the long-term results of truncus arteriosus at the University of California, San Francisco, where a repair in early infancy has been routine since 1975...

OBJECTIVE: To investigate the outcome of mechanical mitral valve replacement in children after up to 11 years of follow up. DESIGN: Retrospective analysis of case records. Operative survivors underwent echocardiographic studies to define current haemodynamic status and prosthetic valve function. SETTING: Tertiary referral centre. PATIENTS: All 54 children who underwent mitral valve replacement between January 1987 and December 1997...

REVIEW
L J Dacey
Pulmonary homografts are used more frequently in cardiac surgery. They are used primarily for reconstruction of the right ventricular outflow tract, both in children with complex congenital disease and in adults undergoing the Ross procedure for aortic valve replacement. They have been used for left ventricular outflow tract reconstruction, but they are less,durable in this high-pressure position. They have excellent hemodynamic characteristics, require no anticoagulation, and are free from problems of thromboembolism...

OBJECTIVES: This study aims to evaluate the efficacy of a low dose warfarin regimen for Chinese children requiring anticoagulation therapy and its safety when monitored on an outpatient basis. Current recommendations are based on extrapolations from the adult experience and a high target international normalised ratio (INR) is adopted amongst the Western countries. METHODOLOGY: This is a 10-year retrospective study from January 1986 to June 1996. Effectiveness of warfarin therapy was monitored by the prothrombin time, standardised and expressed as the INR...

Since September 1979, 53 patients have required operation for systemic atrioventricular valve regurgitation at Children's Hospital and Health Center of San Diego. (Primary repairs of atrioventricular canal defects are excluded from this report.) Diagnoses include single ventricle, cardiomyopathy, congenital mitral insufficiency , Marfan's disease, rheumatic heart disease, and a history of prior repair of atrioventricular canal defect. Ages ranged from 4 months to 19 years; median age is 5 years. In 31 patients, the atrioventricular valve could be repaired...

The surgical considerations, clinical follow-up, and hemodynamic data for 23 patients (age range, 4 months to 80 years) who underwent insertion of a porcinevalved apicoaortic conduit between December, 1976, and June, 1983, are reviewed. All patients had complex forms of left ventricular outflow obstruction. All were symptomatic, and 18 had had 23 prior attempts at surgical relief of the obstruction. There was a total of 6 deaths (26%); 2 were in small children with other complex cardiac malformations, and 2 others in patients who required emergency operation for acute cardiac decompensation...

Management of valve diseases in children demands an eclectic approach by the surgeon. Whenever possible, valve function should be restored by repair rather than prosthetic replacement. Recent evidence firmly demonstrates that there are accelerated calcification and degeneration of porcine heterografts in children, especially in the aortic and mitral positions. For this reason, we reserve the use of heterograft prostheses for the right atrioventricular position and for conduits from the right ventricle to the pulmonary artery...

Since 1964, 56 children (mean age, 6.7 years) underwent repair of incomplete endocardial cushion defects. Forty patients had isolated ostium primum defects. Additional congenital defects were present in 17 patients (30%). All patients underwent patch closure of the ostium primum defect and 47 of 56 patients (84%) underwent mitral valvuloplasty. Hospital mortality was 1.8% (one death). Arrhythmias developed in 7 other patients in the early postoperative period, of which six were transient and resolved completely...
