Area of Science:

  • Pediatric Cardiac Surgery
  • Congenital Heart Disease Management
  • Cardiovascular Surgery

Background:

  • Complex left-ventricular outflow tract obstruction (LVOTO) in infants and children often requires surgical intervention.
  • The standard Konno aortoventriculoplasty combined with the Ross procedure is increasingly utilized for these challenging cases.
  • Aortic valve disease and aortic annular hypoplasia are common comorbidities associated with LVOTO.

Purpose of the Study:

  • To present a modified surgical technique, the 'Mini-Ross-Konno', for managing complex pediatric LVOTO.
  • To evaluate the efficacy of this modified approach in relieving LVOTO.
  • To assess the safety and long-term outcomes of the Mini-Ross-Konno procedure, specifically regarding the avoidance of ventricular septal defects.

Main Methods:

  • A modified Konno aortoventriculoplasty in conjunction with the Ross procedure was performed.
  • The technique was adapted to avoid the creation of a ventricular septal defect (VSD).
  • Surgical outcomes focusing on LVOTO relief and VSD absence were assessed.

Main Results:

  • The modified 'Mini-Ross-Konno' procedure successfully relieved left-ventricular outflow tract obstruction.
  • The technique effectively managed associated aortic valve disease and/or aortic annular hypoplasia.
  • Crucially, the procedure was performed without the complication of a ventricular septal defect.

Conclusions:

  • The 'Mini-Ross-Konno' modification offers a simplified and effective surgical option for pediatric LVOTO.
  • This approach provides optimal and durable relief of LVOTO.
  • Avoiding a VSD contributes to improved outcomes in complex pediatric cardiac surgery.
