title: Minimally invasive congenital cardiac surgery through right anterior minithoracotomy approach.
abstract: BACKGROUND
  Median sternotomy has been the conventional approach for correction of congenital cardiac defects despite poor cosmetic results at times. Right anterior minithoracotomy was, therefore, assessed as an alternative procedure with a better cosmetic outcome.
  
  
  METHODS
  From October 2002 through February 2007, 75 patients underwent correction of congenital cardiac malformations with the use of cardiopulmonary bypass through right anterior minithoracotomy involving a short incision through the fifth intercostal space and the minimally invasive cannulation. Of them, 18 patients were infants, 42 were children, and 15 were adult. The average age was 9.26 +/- 14.1 years (range, 1.2 to 56). The average weight was 19.59 +/- 24.3 kg (range, 8.5 to 118 kg). The corrected defects included atrial septal defect type II, sinus venosus atrial septal defect with partial anomalous pulmonary venous drainage, atrial component of atrioventricular septal defect, perimembranous ventricular septal defects with patent foramen ovale, mitral valve repair (complex), repair of cleft mitral valve, cor triatum atrial septal defect, repair of double-chambered right ventricle and extraction of atrial septal defect closure device. Skin incisions were as long as 5 cm.
  
  
  RESULTS
  There was no operative or late mortality or major morbidity. The mean cardiopulmonary bypass time was 58.67 +/- 35.11 minutes (range, 32 to 263). Sixty-five patients were extubated in the operating room; the remaining 10 patients were extubated within 4 hours. Cosmetic result was very satisfactory in all patients. Two adult patients complained of some right chest musculoskeletal discomfort.
  
  
  CONCLUSIONS
  The right anterior minithoracotomy incision is a safe and effective alternative to a median sternotomy for correction of congenital heart defects. Cosmetic results are highly satisfactory.
