Brief Summary

Anti-cancer immunotherapy, one of the therapeutic revolutions of recent years. It is based on the use of antibodies that block immune system checkpoints that have been hijacked by cancer cells to benefit themselves. Blocking these checkpoints, such as PD-1, unleashes the action of anti-cancer T cells that can then destroy the tumor. The efficacy of these targeted therapies is significant, with an average 40% response rate in patients with metastatic cancers.Immune checkpoint inhibitors (ICIs) are becoming a 1st line therapy in many oncology indications due to their therapeutic line in many oncology indications due to their favorable effect on the prognosis of various prognosis of various cancers Since checkpoints play a key role in controlling the intensity and duration of an immune response, their immune response, therefore, their inhibition exposes to adverse inflammatory or autoimmune effects inflammatory or autoimmune adverse effects that can be severe and sometimes lethal.Most side effects of ICIs occur within the first few months after initiation of treatment. The toxicity of immunotherapy is immunological, all organs including the heart can be including the heart, can be affected.

Cardiac autoimmune involvement in ICIs can involve the myocardium, pericardium, and/or vascular endothelium. These entities may be interrelated or, on the contrary, isolated.

In the last 5 years, the number of described cases of myocarditis associated with ICIstreatment has increased. Their incidence remains low, estimated between 0.5 and 2%. This probably represents the most serious cardiovascular complication, as the mortality attributed to it reaches almost 50%.

In recent years MRI has become very important in the noninvasive diagnosis of acute myocarditis. The latest update of the Lake Louise criteria in 2018 has thus confirmed cardiac MRI in its first place among noninvasive examinations for the diagnosis of myocarditis with a sensitivity of 87.5%, a specificity of 96.2%, and a positive predictive value of 97.2%.
