  • The study focuses on managing spontaneous intracranial hemorrhage (ICH) in patients with mechanical heart devices like total artificial hearts (TAH) and left ventricular assist devices (LVAD).
  • It highlights the challenges ICH presents due to anticoagulation and coagulopathy associated with these devices, emphasizing the need for prompt treatment involving both neurosurgeons and cardiac critical care teams.
  • The research reviewed data from 2013-2016, revealing a high mortality rate and proposing a new multidisciplinary treatment algorithm to improve outcomes for affected patients.

Article Abstract

Background: Spontaneous intracranial hemorrhage (ICH) is frequently managed in neurosurgery. Patients with durable mechanical circulatory support devices, including total artificial heart (TAH) and left ventricular assist device (LVAD), are often encountered in the setting of ICH. Although durable mechanical circulatory support devices have improved survival and quality of life for patients with advanced heart failure, ICH is one of the most feared complications following LVAD and TAH implantation. Owing to anticoagulation and clinically relevant acquired coagulopathies, ICH should be treated promptly by neurosurgeons and cardiac critical care providers. We provide an analysis of ICH in patients with mechanical circulatory support and propose a treatment algorithm.

Methods: We retrospectively reviewed medical records from 2013-2016 for patients with a durable mechanical circulatory device at Banner-University of Arizona Medical Center Tucson. All patients with suspected ICH underwent computed tomography scan of the brain. Anticoagulation was managed by the cardiothoracic surgeon.

Results: In 58 patients, an LVAD (n = 49), TAH (n = 10), or both (n = 1) were implanted. Both acquired von Willebrand disease and spontaneous ICH were diagnosed in 5 patients (8.6%) who underwent LVAD implantation. Seven neurosurgical procedures were performed in 2 patients. The overall mortality rate was 60%. Two patients had little or no deficits after treatment with modified Rankin Scale score of 1 and 2, respectively.

Conclusions: We propose a novel treatment algorithm to manage patients with a LVAD or TAH and ICH, implemented in a multidisciplinary manner to best avoid neurologic and cardiovascular complications.

Patients with restrictive cardiomyopathy (RCM) and hypertrophic cardiomyopathy (HCM) were previously considered poor candidates for mechanical circulatory support due to technical limitations related to restrictive ventricular physiology and small ventricular size, limiting the ability to provide adequate flows and decompress the heart. Literature examining use of extracorporeal membrane oxygenation (ECMO) in this population consists of a single case series reporting no survivors. We report our experience providing ECMO in children with RCM or HCM at a large pediatric quaternary cardiac center.

Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.

Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.

Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.

Mixed Cardiogenic-Vasodilatory Shock: Current Insights and Future Directions.

JACC Adv

January 2025

Division of Cardiology, Department of Medicine, Warren Alpert Medical School of Brown University, and Lifespan Cardiovascular Institute, Providence, Rhode Island, USA.

This state-of-the-art review describes the potential etiologies, pathophysiology, and management of mixed shock in the context of a proposed novel classification system. Cardiogenic-vasodilatory shock occurs when cardiogenic shock is complicated by inappropriate vasodilation, impairing compensatory mechanisms, and contributing to worsening shock. Vasodilatory-cardiogenic shock occurs when vasodilatory shock is complicated by myocardial dysfunction, resulting in low cardiac output.

Up to 50% of patients with pulmonary embolism (PE) experience hemodynamic instability and approximately 70% of patients who die of PE experience an accelerated cascade of symptoms within the first hours of onset of symptoms, thus necessitating rapid evaluation and intervention. Venoarterial extracorporeal membrane oxygenation and other ventricular assist devices, depending on the hemodynamic derangements present, may be used to stabilize patients with massive PE refractory to initial therapies or with contraindications to other interventions. Given the abnormalities in both pulmonary circulation and gas exchange caused by massive PE, venoarterial extracorporeal membrane oxygenation may be considered the preferred form of mechanical circulatory support for most patients.

Background: Acute myocardial infarction-related cardiogenic shock (AMICS) is a severe complication associated with exceedingly high mortality rates. While mechanical circulatory support (MCS) has emerged as a potential intervention, the evidence base for independent MCS use remains weak. In contrast, systematic reviews of observational studies have revealed significant mortality reduction when a combination of MCS was used: VA-ECMO in conjunction with a left ventricular (LV) unloading device (Impella or IABP).
