Impact of a surgical approach for implantation of durable left ventricular assist devices in patients on extracorporeal life support

Background The aim of this study was to evaluate the impact of the surgical approach on the postoperative outcome in patients who underwent left ventricular assist device (LVAD) implantation after having received veno-arterial extracorporeal life support (va-ECLS) using data from a European registry (ECLS-VAD). Five hundred and thirty-one patients were included. Methods A propensity score-adjusted outcome analysis was performed, resulting in 324 patients in the full sternotomy (FS) group and 39 in the less invasive surgery (LIS) group. Results The surgery lasted in median 236 min in the FS group versus 263 min in the LIS group (p = 0.289). The median chest tube output during the first 24 h was similar in both groups. Patients who underwent implantation with an FS required more blood products during the first 24 postoperative hours (median 16 vs. 12, p = 0.033). The incidence of revision due to bleeding was also higher (35.5 vs. 15.4%, p = 0.016). A temporary postoperative right ventricular assist device was necessary in 45.1 (FS) versus 23.1% (LIS) of patients, respectively (p = 0.067). No stroke occurred in the LIS group during the first 30 days after surgery (7.4% in the FS group). The incidence of stroke and of renal, hepatic, and respiratory failure during the follow-up was similar in both groups. The 30-day and one-year survival were similar in both groups. Conclusion LIS for implantation of a durable LVAD in patients on va-ECLS implanted for cardiogenic shock is associated with less revision due to bleeding, less administration of blood products and absence of perioperative stroke, with no impact on survival

Rescue Surgery 19 Years after Composite Root and Hemiarch Replacement

A 59-year-old male patient with Marfan's syndrome was referred to our clinic due to acute chest pain. His medical history contains complex surgery for type A aortic dissection 19 years ago including composite root replacement using a mechanical aortic valve. Immediate computed tomography indicated perforation at the distal ascending aortic anastomosis plus complete avulsion of both coronary ostia. The patient underwent successful rescue surgery with ascending aortic and arch replacement using a modified Cabrol technique

Is implantable cardioverter defibrillator surgery in patients with an implanted left ventricular assist device safe under uninterrupted oral anticoagulation?

Abstract Background: Implantable cardioverter-defibrillator (ICD) surgery in patients with implanted left ventricular assist devices (LVAD) is associated with an increased risk of bleeding complications because of the need to ensure that these patients are adequately anticoagulated. Our study aimed to evaluate the safety of our new strategy of uninterrupted oral anticoagulation compared to heparin-bridging during the surgical interval. Methods: Between January 2009 and January 2020, 116 patients with LVAD underwent ICD surgery. Since January 2015, 60 patients were operated under continued sufficient oral anticoagulation with a vitamin k antagonist (VKA group). Fifty-six patients underwent a heparin-bridging regimen (heparin group). Demographics, perioperative data, complications, and mortality were analyzed. Results: Bleeding complications attributable to the surgical intervention occurred more often (19.6% vs. 10.0%, p = 0.142) and at a higher rate of re-exploratory surgery (14.3% vs. 5.0%, p = 0.088) in the heparin group without reaching statistical significance. Moreover, the heparin group patients' postoperative total length of stay was 10 days longer (17.8 ± 23.8 days vs. 8.3 ± 9.5 days, p = 0.007). There were no procedure-related deaths, no thromboembolic events, and no LVAD-related thrombosis. Conclusion: Our strategy of uninterrupted oral anticoagulation is safe and results in a reduction by more than half the number of days in hospital without an increase in adverse events
