Are we improving after 10 years of humanitarian paediatric cardiac assistance

BACKGROUND Paediatric cardiovascular services are frequently absent or poorly developed in many countries around the world. Our foundation made 83 trips in support of cardiovascular services between April 1993 and March 2003 to help alleviate this problem. In this study, we present an analysis of our results over these period of 10 years. METHODS We performed a review of all available records relating to the trips, including patient databases, audited financial statements, donated product inventory lists, lists of team members, and follow-up data from the host sites concerning the state of the patients treated. RESULTS We made 83 trips to 14 countries, 40 of these being in Central Europe, 5 in Eastern Europe, 10 in Caribbean, and Central America, 18 in South America, 9 in Asia, and 1 in the Middle East. In the first 5 years, we made 23, as opposed to 60 in the second 5 years, this difference being significant (p less than 0.01). The total number of primary operations performed over 10 years was 1,580. The number of procedures performed yearly increased over the two intervals from 97.0 plus or minus 32.7 to 219.0 plus or minus 41.7, p less than 0.002. The probability of survival between the periods increased from 84.6 to 93.3 per cent, and this was also significantly different (p less than 0.001). Overall, the rate of survival for the period of 10 years was 90.5 per cent. Moreover, the value of services donated to support each trip also differed significantly, decreasing from 105,900 dollars plus or minus 14,581 dollars for the first period to 54,617 dollars plus or minus 11,425 dollars for the second period (p less than 0.001). CONCLUSIONS Improving paediatric cardiac services in under-served countries requires significant financial and personnel commitments, but can produce reasonable outcomes.

Paediatric cardiac assistance in developing and transitional countries: the impact of a fourteen year effort.

BACKGROUND Paediatric cardiac services are poorly developed or totally absent in underdeveloped countries. Institutions, foundations and interested individuals in those nations in which sophisticated paediatric cardiac surgery is practised have the ability to alleviate this problem by sponsoring paediatric cardio-surgical missions to provide care, and train local caregivers in developing, transitional, and third world countries. The ultimate benefit of such a programme is to improve the surgical abilities of the host institution. The purpose of this report is to present the impact of our programme over a period of 14 years. METHODS We specifically reviewed our database of patients from our missions, our team lists, surgical results, and the number and type of personnel trained in the institutions that we have assisted. In order for the institution to be entered into the study, the foundation had to provide at least 2 months of training. In addition, the institution had to respond to a simple questionnaire concerning the number and types of surgery performed at their facility before and after intervention by the foundation. RESULTS We made 140 trips to 27 institutions in 19 countries, with 12 of the visited institutions qualifying for inclusion. Of these, 9 institutions reported an increase in the number and complexity of cases currently being performed in their facility since the team intervened. This goal had not been accomplished in 3 institutions. The reasons for failure included the economic situation of the country, hospital and national politics, personality conflicts, and continued lack of hardware and disposables. CONCLUSIONS Paediatric cardiac service assistance can improve local services. A significant commitment is required by all parties involved.

Pediatric Cardiovascular Surgery in South America: Current Status and Regional Differences

Very little information is available about the epidemiology of congenital heart disease in developing parts of the world, including South America. This article describes the incidence of congenital cardiac disease, the different treatment rates among countries, and future solutions for achieving improved coverage for the children with cardiac diseases in South America. An incidence of congenital cardiac disease of 8 per 1000 live births appears to be a fair approximation for the population of the world and also the population in South America. Nevertheless, a wide variation exists in the observed incidence of congenital cardiac disease in South American countries, which can be partly explained by inequalities in the access to diagnosis, differences in the diagnostic criteria, and true regional variations. It is estimated that 58,718 children are born yearly with congenital heart disease in South America. Brazil, Colombia, and Argentina have the highest number, followed by Peru, Venezuela, Chile, Ecuador, Bolivia, Paraguay, Uruguay, and Guyana. It is also estimated that in South America, 24,081 children per year with a new diagnosis of congenital cardiac disease do not receive any treatment. This paper provides strategies for improving the access to and quality of pediatric cardiac surgery in South America.

Successful Management of Acute Failure of the Systemic Right Ventricle with Cardiac Resynchronization Therapy

Management of systemic right ventricular (RV) failure can be challenging. Anatomical abnormality due to congenital heart disease adds to the complexity when interventions are performed. We report a patient with acute systemic RV failure who was successfully managed with cardiac resynchronization therapy.

Anomalous left coronary artery from the pulmonary artery: intermediate results of coronary elongation

A two coronary system is preferred for correcting anomalous left coronary artery from the pulmonary artery (ALCAPA); however, translocation is not always possible. In countries where neonatal arterial switch operations have not been perfected coronary transfer can be difficult. The purpose of this report is to describe the intermediate results using the coronary elongation and translocation technique in developing countries. Records of patients undergoing operation by the International Childrens Heart Foundation team were reviewed (April 1993-October 2008) for those undergoing ALCAPA repair. All patients received a 2-D echocardiographic-color Doppler examination prior to discharge and at follow-up. A total of 13 patients were identified, age ranged from 9 days to 41 years. All but one patient were operated upon at one of our affiliate hospitals in Croatia, Belarus, China and Colombia. All patients presented with moderate to severe mitral regurgitation and cardiac failure. Follow-up ranged from six months to 9.5 years postoperatively. Color Doppler showed a patent left coronary artery; echocardiography estimated a normal left ventricular ejection fraction and improved mitral regurgitation in all patients. The technique provides an alternative approach to translocation for ALCAPA in countries where routine neonatal coronary transfer techniques may not be perfected. Intermediate results are comparable to translocation.

Surgical Correction of Truncus Arteriosus With Unusual Origin of the Right Coronary Artery.

An 11-year-old male with a diagnosis of truncus arteriosus (common arterial trunk) with origin of the right coronary artery anteriorly from the pulmonary segment of the common trunk underwent reparative surgery. The pulmonary trunk was long, and it had a kink with stenosis that protected the distal pulmonary vascular bed from elevated pressure. Adequate flow allowed well-developed distal branch pulmonary arteries. An oval incision was made in the pulmonary trunk, which created a flap. At its center was the right coronary artery. This flap, which remained attached to the aorta proximally, was then used to close the aortic defect. The segment of the pulmonary trunk with stenosis was resected. The patient’s pericardium was used to fashion a valved conduit that was interposed between the right ventricle and the confluence of the pulmonary artery branches.
