Complex two-ventricle reconstruction and conduction protection · Boston, United States
Sitaram Emani co-directs Boston Children’s Complex Biventricular Repair Program. The work focuses on whether unusual ventricular connections, valves and outflow routes can be reconstructed so that both ventricles support circulation.
The programme uses detailed planning and 3D models for difficult ventricular relationships, with tailored outflow and valve reconstruction.

A 2019–2022 study compared 149 mapped with 201 unmapped repairs; lower heart-block/pacemaker frequency occurred in selected anatomical subgroups.
In a 25-patient Yasui series, freedom from right-ventricle-to-pulmonary-artery conduit reoperation was 48% at median five-year follow-up.

A 2024 programme study compared intraoperative conduction mapping with unmapped complex repairs. Lower postoperative heart-block/pacemaker frequency occurred in selected anatomical subgroups.
How to interpret this: Observational comparison; risk was not eliminated and not every subgroup benefited. Results belong to the programme.
The historical Yasui series describes preservation of ventricular function alongside a substantial later burden of right-ventricle-to-pulmonary-artery conduit reoperation.
How to interpret this: Only 25 selected patients treated across 1989–2021; no personal success rate or prediction for a new child.

Boston, United States
Boston Children’s Complex Biventricular Repair Program evaluates difficult ventricular relationships using detailed imaging and 3D models. Its research addresses both protection of the conduction system during repair and the later burden of conduit procedures.
