Infective endocarditis in patients with ventricular septal defects can prove life threatening due to acute heart failure or septic embolization. Persistent postoperative risk is bacterial colonization of prosthetic material. We designed the Antibiotic Sandwich Patch to reduce this risk, using a double layer of autologous pericardium containing antibiotic powder. Five patients were managed with this technique for closure of ventricular septal defects complicated by acute infective endocarditis. No colonization of the patches occurred after a median follow up of 1.5 years. This technique reduced the risk of bacterial colonization of the antibiotic sandwich patch, offering an additional surgical option.

A large underserved population of children with congenital cardiac malformation (CCM) exists in many developing countries. In recent years, several strategies have been implemented to supplement this need. These strategies include transferring children to first-world countries for surgical care or the creation of local pediatric cardiovascular surgical programs. In 1997, an effort was made to create a comprehensive pediatric cardiac care program in Guatemala. The objective of this study is to examine the outcome analysis of the Guatemala effort. The goals of our new and first pediatric cardiac care program were to: 1) provide diagnosis and treatment to all children with a CCM in Guatemala; 2) train of local staff surgeons, 3) established a foundation locally and in the United States in 1997 to serve as a fundraising instrument to acquire equipment and remodeling of the pediatric cardiac unit and also to raise funds to pay the hospital for the almost exclusively poor pediatric cardiac patients. The staff now includes 3 surgeons from Guatemala, trained by the senior surgeon (A.R.C.), seven pediatric cardiologists, 3 intensivists, and 2 anesthesiologists, as well as intensive care and ward nurses, respiratory therapists, echocardiography technicians, and support personnel. The cardiovascular program expanded in 2005 to 2 cardiac operating rooms, 1 cardiac catheterization laboratory, 1 cardiac echo lab, 4 outpatients clinics a 6-bed intensive care unit and a 4-bed stepdown unit, a 20 bed general ward (2 beds/room) and a genetics laboratory. Our center has become a referral center for children from Central America. A total of 2,630 surgical procedures were performed between February 1997 and December 2007, increasing the number of operations each year. Postoperative complication occurred in 523 of 2,630 procedures (20%). A late follow-up study was conducted of all the patients operated from 1997 to 2005. Late mortality was 2.7%. Development of a sustainable pediatric cardiac program in emerging countries presents many difficult challenges. Hard work, perseverance, adaptability, and tolerance are useful aptitudes to develop a viable PCP in an "emerging" country. We are not in favor of Medical-Surgical Safari efforts, unless these efforts include training of a local team and eventual unit independence. It helps if an experienced (+/- senior/retired!) surgeon leads this effort on a full-time, pro bono basis. Local and international fund raising is essential to complement vastly insufficient government subsidies.

A rare type of patent ductus arteriosus called window ductus was identified in association with a right aortic arch in a 1-year-old child who was referred for closure of a membranous ventricular septal defect.

BACKGROUND: Minimally invasive surgery for the closure of a large patent ductus arteriosus (PDA) using an extrapleural technique offers an alternative to other minimally invasive approaches such as video-assisted thoracoscopic surgery or interventional cardiologic procedures. METHODS: Between August 1999 and December 2003, 513 patients with PDA were admitted to Unidad de Cirugia Cardiovascular de Guatemala, of whom 327 (64%) were considered surgical candidates. Of these, 218 (67%) were selected for surgical extrapleural (SEP) closure initially by weight (< 10 kg) and a ductal diameter at the pulmonary end of greater than 4 mm. Subsequently, we included also patients who weighed more than 10 kg. Median age at operation was 51 months (range 5 days to 38 years). RESULTS: Median operating time was 32 minutes (range 23 to 52 minutes). All 218 patients had SEP closure and were extubated in the operating room. There were no hospital deaths. Two patients required a blood transfusion. Two additional patients bled postoperatively, requiring reoperation. A pneumothorax occurred in 3 patients that required a chest tube. The 6-month follow-up revealed residual ductal shunts in 2 patients that were closed percutaneously with a coil. The treatment of the remaining 295 patients included a surgical transpleural (STP) approach in 109 (37%) and transcatheter closure in 186 (63%), with a coil in 110 (37%) and an Amplatzer device in 76 (26%). CONCLUSIONS: Minimally invasive closure of a PDA through a short, 3-cm to 5-cm skin and muscle-sparing posterior thoracotomy and an SEP approach provides a convenient and safe technique with a low incidence of complications and also a cost-saving option compared with other invasive techniques.
