Three-step preoperative sequential planning for pulmonary valve replacement in repaired tetralogy of Fallot using computed tomography.

ABSTRACT:

Objectives

Our goal was to compare results between a standard computed tomography (CT)-based strategy, the 'three-step preoperative sequential planning' (3-step PSP), for pulmonary valve replacement in repaired tetralogy of Fallot versus a conventional planning approach.

Methods

We carried out a retrospective study with unmatched and matched groups. The 3-step PSP comprised the planning of mediastinal re-entry, cannulation for cardiopulmonary bypass (CPB) and the main procedure, using standard 3-dimensional videos. Operative times (skin incision to CPB, CPB time, end of CPB to skin closure and cross-clamp time) as well as postoperative length of stay and in-hospital mortality were compared.

Results

Eighty-two patients (49% classical tetralogy of Fallot) underwent an o
