Exploring Brain and Heart Interactions during Electroconvulsive Therapy with Point-of-Care Ultrasound.
Med Sci (Basel)
March 2024
Department of Anesthesia, Critical Care and Pain Medicine, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114, USA.
Background: Electroconvulsive therapy (ECT) is a procedure commonly used to treat a number of severe psychiatric disorders, including pharmacologic refractory depression, mania, and catatonia by purposefully inducing a generalized seizure that results in significant hemodynamic changes as a result of an initial transient parasympathetic response that is followed by a marked sympathetic response from a surge in catecholamine release. While the physiologic response of ECT on classic hemodynamic parameters such as heart rate and blood pressure has been described in the literature, real-time visualization of cardiac function using point-of-care ultrasound (POCUS) during ECT has never been reported. This study utilizes POCUS to examine cardiac function in two patients with different ages and cardiovascular risk profiles undergoing ECT.

Eur Heart J Case Rep

Division of Cardiology, Department of Internal Medicine, The Jikei University School of Medicine, 3-25-8 Nishi-shimbashi, Minato-ku, Tokyo 105-8461, Japan.
Background: Cardiac strangulation (CS) is a rare but potentially devastating complication caused by the leads of an epicardial pacemaker (EP). Most cases have been reported in paediatric patients, and there has been no report wherein the diagnosis was made in a living, adult patient, and treated successfully.
Case Summary: A 31-year-old woman with a history of atrial septal defect (ASD) patch closure and EP implantation for congenital atrial stand-still presented with dyspnoea on exertion.
Complete flow control using transient concurrent rapid ventricular pacing or intravenous adenosine and afferent arterial balloon occlusion during transvenous embolization of cerebral arteriovenous malformations: case series.
J Neurointerv Surg
April 2021
Department of Neurosurgery, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, Buffalo, New York, USA
Background: There are no reports that describe complete flow control using concurrent transient rapid ventricular pacing or intravenous (IV) adenosine and afferent arterial balloon flow arrest to aid transvenous embolization of cerebral arteriovenous malformations (AVM). We describe our experience with the use of this technique in patients undergoing transvenous AVM embolization.
Methods: Consecutive patients in whom transvenous embolization was attempted at our institute between January 2017 and July 2019 were included.
Circulatory support for prolonged electro-mechanical standstill in fulminant pediatric myocarditis.
Int J Artif Organs
June 2021
Department of Cardiovascular Surgery, Children's National Heart Institute, Children's National Hospital, Washington DC, USA.
Pediatric patients with fulminant myocarditis can rarely present with complete heart block with severe hemodynamic compromise, cardiac arrest and require circulatory support. Additionally, patients with cardiac dysfunction that require extracorporeal membrane oxygenation (ECMO) support sometimes develop cardiac stun or standstill. These factors are associated with extremely poor survival.

Department of Cardiovascular Surgery, Mackay Memorial Hospital, Taipei, Taiwan.
BACKGROUND Venom related fulminant myocarditis is uncommon. The clinical course varies, and histopathology is usually unclear, however, refractory cardiogenic shock is rare. CASE REPORT We reported a case of a 36-year-old female who developed fever and cardiogenic shock 3 days after a bee sting.
