Summary
Transventricular dilation (TVD) offers a life-saving early treatment for critical aortic stenosis (CAOS) in newborns. This approach demonstrated no early mortality in 11 cases, making it a viable alternative for critical congenital heart disease.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Critical aortic stenosis (CAOS) is a severe condition incompatible with life after ductal closure.
- Early diagnosis and intervention are crucial for neonatal survival.
Purpose of the Study:
- To evaluate the efficacy and safety of transventricular dilation (TVD) as an initial treatment for isolated CAOS in neonates.
- To assess the long-term outcomes and potential complications of TVD in this patient population.
Main Methods:
- Retrospective analysis of 11 consecutive neonates diagnosed with isolated CAOS.
- Noninvasive diagnosis at a mean age of 4 days.
- Surgical intervention with TVD at a mean age of 4.7 days.
Main Results:
- No early mortality was observed in the 11 treated patients.
- Two late deaths occurred due to fibroelastosis in patients with the smallest aortic annulus.
- Two patients required subsequent aortic root replacement, facilitated by initial TVD.
Conclusions:
- Transventricular dilation (TVD) is a safe and effective early treatment for critical aortic stenosis (CAOS) in neonates.
- TVD can prevent early mortality and potentially facilitate later elective surgical interventions.
- Careful patient selection and monitoring are important, especially for those with small aortic annulus diameters.
