ObjectivesThe aim of the present study was to describe a bicaval endovascular occlusion technique in minimally invasive tricuspid valve (TV) surgery in patients with previous cardiac surgery.DesignCase series.SettingSingle tertiary university center.ParticipantsThe study comprised ten patients.InterventionsEndovascular occlusion of vena cavae for minimally invasive TV redo surgery.Measurements And Main ResultsBetween 2008 and 2017, ten patients with previous cardiac surgery underwent TV minimally invasive surgery (repair or replacement; isolated or with concomitant procedures) using the Coda balloon catheter (Cook Medical, Bloomington, IN) to occlude both vena cavae. Data were collected retrospectively from electronic medical records. Superior and inferior vena cava occlusion with Coda balloon catheters was successful with no complications. The drainage of the vena cavae was optimal with excellent surgical exposure. Cardiopulmonary bypass time was 131 ± 119 minutes, with 30% of patients undergoing aortic clamping (two with a Chitwood clamp, one with an endoaortic balloon). Intensive care unit length of stay was 3.9 ± 2.7 days, and the in-hospital mortality rate was 30%.ConclusionBicaval endovascular occlusion of vena cavae is a feasible and effective technique in patients with previous cardiac surgery who are undergoing a minimally invasive TV procedure. The high mortality rate is associated with the inherent risk of a redo surgery involving the TV.Crown Copyright © 2020. Published by Elsevier Inc. All rights reserved.
