Introduction: Waldenström's macroglobulinemia is a hematological neoplasm belonging to the group of monoclonal gammopathies, which includes systemic symptoms and those related to an increase in M paraprotein. Objective: To describe a case of cardiac amyloidosis associated with macroglobulinemia. Clinical case: Male patient who was admitted for asthenia, dysphonia, and who, during his evolution, developed progressive dyspnea, heart failure and pleural effusion. Additionally, echocardiography showed myocardial granular pattern, while pleural biopsy was positive for Congo red staining. Subsequently, he received treatment with bortezomib, dexamethasone and rituximab, with favorable evolution. Conclusions: In this disease, early diagnosis is an important advantage for survival. Therefore, its management is palliative of cardiac manifestations. The present case shows a diagnostic challenge, i...

Cardiotoxicity is a relatively new clinical entity which, in the case of heart failure, is a marker of poor prognosis in cancer survivors who have received more frequent treatments with anthracyclines or trastuzumab. In these patients, detecting a cardiac dysfunction in the subclinical stage can reveal early myocardial involvement and avoid further damage to the heart. Technological advances in imaging, such as the global longitudinal strain, and the increase in troponin I enable the detection of this condition. This case report involves a 17-year-old female patient who was diagnosed with osteosarcoma in her left leg and received anthracyclines. In the cardiovascular evaluation, she was asymptomatic, and showed normal left ventricular function (60 %), decreased strain rate (-15 %) and elevated troponin I levels (115 ng/mL). Asymptomatic cardiac dysfunction was diagnosed and carvedilol 6....

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy by significantly improving long-term outcomes across multiple malignancies. Despite their benefits, ICIs can lead to immunerelated adverse events, including rare but severe cardiovascular toxicity such as myocarditis, which can be life-threatening. This comprehensive review aims to explore and discuss the mechanisms, clinical presentation, diagnostic challenges, and management strategies of ICI-induced myocarditis, emphasizing the need for early detection and timely intervention. As the use of ICIs continues to expand, further research is essential to fully elucidate the underlying mechanisms and optimize therapeutic strategies to mitigate this potentially fatal complication while maintaining the efficacy of cancer therapy.
