Considerations on the Diagnosis and Prognosis of Primary Cardiac Lymphoma

Thalisson Gonçalves Almeida et al. Tales Gabriel Ferro de Oliveira Gustavo da Silva Soares Pedro Pereira Tenório

Dear Editor,

We would like to congratulate the authors on their relevant case report, “Cardiac Lymphoma: A Case Report,” published in the Arquivos Brasileiros de Cardiologia (ABC Cardiol). The article addresses a rare and challenging clinical condition, primary cardiac lymphoma (PCL), which, as highlighted in the article, is an aggressive tumor with a poor prognosis and nonspecific symptoms, making early diagnosis difficult. Among the article’s strengths, we highlight the rarity of the case, as it is a diffuse large B-cell lymphoma (DLBCL) with primary cardiac involvement, given the low incidence of these tumors (approximately 0.04% of primary malignant cardiac tumors, with lymphomas representing about 1.3% of these), with DLBCL being the most common subtype, frequently located in the right chambers of the heart.^,

Left Internal Thoracic Artery Fistula to the Bronchial Artery: a Rare Cause of Coronary Flow Theft

Marcela Gomes de Souza et al. Alice Mirane Malta Carrijo Vinicius Ferreira Aratani Flávia Bittar Britto Arantes

Introduction

The left internal thoracic artery (LITA) fistula to the pulmonary artery (PA) and/or its branches is a rare condition that was first described in 1947 by Burchell and Clagett and can be acquired or congenital. Its etiologies include, trauma, infection, neoplasms, and mainly myocardial revascularization surgery (MRS).^, The surgical manipulation of the intrathoracic vessels during MRS may predispose a patient to postoperative LITA fistulization to the PA, causing coronary flow leakage and myocardial ischemia. LITA should be considered an etiological diagnosis in cases of persistent angina after MRS.^, Its diagnosis requires coronary cineangiography,^– and its treatment options include conservative drug therapy, surgical ligation, or endovascular intervention.
