Indications and results for hybrid interventions in patients with congenital heart disease

Intraoperative Sapien S3 Valve Placement in 2 Patients With Multi-Valvar Disease Operation: A Unique Hybrid Procedure

There has been a paradigm shift in the management of patients with congenital heart disease with a move away from conventional surgical treatment in favor of a percutaneous catheter-based approach across the spectrum of valvular heart diseases. The Sapien S3 valve implantation in the pulmonary position has been previously reported using a conventional transcatheter approach in patients with pulmonary insufficiency due to an enlarged right ventricular outflow tract. In this report, we present 2 unique cases of intraoperative hybrid implantation of Sapien S3 valves in patients with complex pulmonic and tricuspid valvular disease.

Single‐Center Experience of Hybrid Pulmonary Valve Replacement Using Left Anterior Thoracotomy With Pulmonary Artery Plication in Patients With Large Right Ventricular Outflow Tract

Background

Until recently, a large right ventricle outflow tract interfered with the feasibility of standard transcatheter pulmonary valve replacement (PVR). We are describing our experience using a hybrid approach for PVR using a left anterior thoracotomy approach to allow for plication of the main pulmonary artery followed by a transcatheter PVR using a Sapien S3 valve.

Methods and Results

This is a single‐center, retrospective review of patients who were evaluated to be appropriate for a hybrid PVR approach. The patients' demographics, procedure details, and follow‐up data were collected. Between May 2018 and April 2021, a total of 11 patients presented for hybrid transcatheter PVR. The median age and weight were 24 years (interquartile range, 19–43 years) and 81.8 kg (interquartile range, 69–91 kg), respectively. Nine out of 11 patients received a transcatheter PVR after main pulmonary artery plication. There were no procedurally related deaths. One major complication was encountered in which the valve was malpositioned requiring successful surgical PVR. Minor complications included acute kidney injury (n=1) and a broken rib (n=1). The median length of stay was 4 days (interquartile range, 2–4 days), with median follow‐up of 7 months (interquartile range, 3–18 months). A well‐functioning pulmonary valve was observed in all patients at the last follow‐up.

Conclusions

A hybrid approach using left anterior thoracotomy with pulmonary artery plication followed by transcatheter Sapien S3 PVR provides a less‐invasive option for patients with an enlarged right ventricular outflow tract. Preliminary results demonstrated this to be a safe option with good short‐term outcomes.
