Cardiotoxicity and peri-operative considerations in immune checkpoint inhibitor and chimeric antigen receptor T-cell therapy: a narrative review.
Anaesthesia

Department of Cardiovascular Medicine, Department of Medicine, Lahey Hospital and Medical Center, Burlington, MA, USA.
Introduction: Immunotherapy has transformed cancer treatment, particularly with immune checkpoint inhibitors and chimeric antigen receptor T-cell therapy. Despite their efficacy, these therapies can induce cardiotoxicity, presenting significant clinical challenges. Immune checkpoint inhibitors can cause myocarditis; pericarditis; arrhythmias; and myocardial infarction through immune-mediated inflammation.

Division of Hematology, Department of Medicine, Mayo Clinic, Rochester, MN, USA.
Background: Cardiac AL and ATTR are potentially fatal cardiomyopathies. Current therapies do not address mechanisms of tissue dysfunction because these remain unknown. Our prior work focused on the amyloid plaque proteome, which may not capture tissue-wide proteomic alterations.

: Currently, the most popular techniques for orthotopic heart transplantation (OHTx) are bicaval and total OHTx. Although bicaval OHTx has shown advantages over the biatrial approach, comparisons between bicaval and total OHTx reain limited. To compare the functional and morphological characteristics of the left atrium (LA) in patients after bicaval and total OHTx.

A previously healthy, 28-year-old man presented with a two-day history of diarrhea and chest pain, suggestive of infectious myocarditis. Initial workup revealed elevated troponin-I levels and diffuse ST-segment elevations on electrocardiogram (ECG). Transthoracic echocardiography showed a reduced left ventricular ejection fraction (40-45%), posteroinferior wall akinesis, and a small pericardial effusion.

Aim: to assess the relation of focal and diffuse left ventricular (LV) fibrosis to left bundle branch block (LBBB).
Materials And Methods: 60 patients with dilated cardiomyopathy and LBBB (DCM-LBBB), 50 DCM-nonLBBB patients, 15 patients with LBBB and structurally normal heart (idiopathic LBBB) and 10 healthy volunteers (HV) underwent cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE). LGE LV images were post-proceed for core scar (CS) and gray zone (GZ) calculation.
