Long-Term Follow-Up of Survivors of Extracorporeal Life Support Therapy for Cardiogenic Shock: Are They Really Survivors?
Background and Objectives: Cardiogenic shock (CS) is a medical emergency associated with a
high mortality rate. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has become
an accepted therapy for CS. Despite widely available data for short-term survival rates, there are
only limited data available regarding long-term outcomes following successful VA-ECMO therapy.
Materials and Methods: We analyzed the demographics, past medical history, adverse events, and
outcomes of survivors who received VA-ECMO support for CS at our center from January 2012 to
December 2019. Post-cardiotomy cases were excluded. Results: A total of 578 VA-ECMO implantations
on 564 consecutive patients due to CS were identified during the study period. Successful weaning
was achieved in 207 (36.7%) patients. Among the survivors, 126 (63%) patients received VA-ECMO
therapy without preceding cardiac surgery during their current admission. A follow-up exceeding
12 (mean: 36 ± 20.9) months was available in a total of 55 (43.7%) survivors. The mean VA-ECMO
perfusion time was 10.9 (±7.7) days with a mean intensive care unit (ICU) stay of 38.2 (±29.9) days
and a mean hospital stay of 49.9 (±30.5) days. A total of 3 deaths were recorded during long-term
follow-up (mean survival of 26 ± 5.3 months). Conclusions: Despite the high mortality associated
with VA-ECMO therapy, a long-term follow-up with an acceptably low rate of negative cardiac
events can be achieved in many survivors. We observed an acceptable low rate of new cardiac
events. Further evaluation, including a quality-of-life assessment and a close follow-up for rarer
complications in these patients, is needed to elucidate the longer-term outcomes for survivors of
invasive VA-ECMO therapy
Cardiac Myxoma and Cerebrovascular Events: A Retrospective Cohort Study
Background: Cardiac myxoma (CM) is the most frequent, cardiac benign tumor and is associated with enhanced risk for cerebrovascular events (CVE). Although surgical CM excision is the only curative treatment to prevent CVE recurrence, in recent reports conservative treatment with antiplatelet or anticoagulant agents in high-risk patients with CM-related CVE has been discussed.Methods: Case records at the University Hospital of TĂĽbingen between 2005 and 2017 were screened to identify patients with CM-related CVE. Clinical features, brain and cardiac imaging findings, histological reports, applied treatments and long-term neurological outcomes were assessed.Results: 52 patients with CM were identified and among them, 13 patients with transient ischemic attack, ischemic stroke or retinal ischemia were included to the (to our knowledge) largest reported retrospective study of CM-related CVE. In all identified patients, CVE was the first manifestation of CM; 61% suffered ischemic stroke, 23% transient ischemic attack and 15% retinal ischemia. In 46% of the patients, CVE occurred under antiplatelet or anticoagulation treatment, while 23% of the patients developed recurrent CVE under bridging-antithrombotic-therapy prior to CM surgical excision. Prolonged time interval between CVE and CM-surgery was significantly associated with CVE recurrence (p = 0.021). One patient underwent i.v. thrombolysis, followed by thrombectomy, with good post-interventional outcome and no signs of hemorrhagic transformation.Discussion: Our results suggest that antiplatelet or anticoagulation treatment is no alternative to cardiac surgery in patients presenting with CM-related CVE. We found significantly prolonged time-intervals between CVE and CM surgery in patients with recurrent CVE. Therefore, we suggest that the waiting- or bridging-interval with antithrombotic therapy until curative CM excision should be kept as short as possible. Based on our data and review of the literature, we suggest that in patients with CM-related CVE, i.v. thrombolysis and/or endovascular interventions may present safe and efficacious acute treatments
