Pulmonary insufficiency requiring reintervention frequently occurs after primary tetralogy of Fallot repair. Repeat interventions present a challenge for both the surgeon and patient. We compare a minimally invasive, 5 cm left anterior mini-incision to redo median sternotomy for pulmonary valve replacement in tetralogy of Fallot patients.
Methods:
Following Internal Review Board approval, we conducted a single institution retrospective review of patients with tetralogy of Fallot who underwent pulmonary valve replacement via redo median sternotomy or left anterior mini-incision between 13 July, 2016 and 6 March, 2020.
Results:
Twenty-three patients underwent pulmonary valve replacement following primary tetralogy of Fallot repair between March 2016 and March 2020. Twelve patients received a redo-median sternotomy from March 2016 to August 2018. Left anterior mini-incision was first offered in August of 2018 and was chosen by all eleven patients thereafter. The two groups had similar baseline characteristics including preoperative pulmonary valve dysfunction. Early trends suggest a longer cardiopulmonary bypass time for patients who received left anterior mini-incisions. Other outcomes were comparable, including operative times, blood product requirements, residual pulmonary valve dysfunction, postoperative pain, narcotic requirements, ICU length of stay, total length of stay, and postoperative complications.
Conclusions:
In patients who have previously undergone primary repairs of tetralogy of Fallot, outcomes for pulmonary valve replacement via left anterior mini-incision are comparable to those via redo median sternotomy.
