Aortoventriculoplasty in children.

M S Schaffer, D N Campbell, D R Clarke

    The Journal of Thoracic and Cardiovascular Surgery
    |September 1, 1986
    PubMed
    Summary

    Aortoventriculoplasty in children with hypoplastic left ventricular outflow tract is a safe and effective surgical option. This procedure demonstrated good long-term outcomes with no thromboembolic or hemorrhagic complications.

    Area of Science:

    • Pediatric Cardiac Surgery
    • Congenital Heart Disease Management
    • Aortic Valve Surgery

    Background:

    • Aortoventriculoplasty addresses complex left ventricular outflow tract obstructions in pediatric patients.
    • Indications include aortic valve issues and subaortic stenosis unsuitable for standard valve replacement.
    • Previous cardiac surgeries are common in this patient population.

    Purpose of the Study:

    • To evaluate the safety and efficacy of aortoventriculoplasty in pediatric patients.
    • To assess long-term outcomes and complication rates.
    • To determine the viability of this surgical approach for hypoplastic left ventricular outflow tract.

    Main Methods:

    • Aortoventriculoplasty was performed on 16 children (5 months to 17 years) between 1980 and 1984.
    • Patients had various aortic valve conditions or subaortic stenosis.
    • Postoperative management included anticoagulation with warfarin and antiplatelet agents.

    Main Results:

    • 13 long-term survivors (14-38 months follow-up) showed good outcomes.
    • 12 survivors were asymptomatic with normal exercise tolerance.
    • No thromboembolic or hemorrhagic complications were reported; three residual VSDs required repair.

    Conclusions:

    • Aortoventriculoplasty is well-tolerated in pediatric patients.
    • It is a viable surgical option for managing hypoplastic left ventricular outflow tract.
    • The procedure offers favorable long-term results with effective anticoagulation management.
