This meta-analysis indicated moderate success for PTFE bypass grafts to infrapopliteal arteries, but the role of adjunctive procedures at the distal anastomosis remains uncertain.

Hypertrophic cardiomyopathy (HCM) may be associated with considerable mortality in athletes. However, differentiating myocardial hypertrophy as a physiological adaptation of the heart to exercise can be a clinical challenge. In this context, nuclear magnetic resonance imaging has been shown to be a essential exam for diagnostic elucidation. The case report aimed to depict a young athlete with syncope and an initial investigation suggestive of HCM, which was excluded after deconditioning and serial MRI.

Background: Primary cardiac neoplasms are rare, and a correct diagnosis is essential to planning the most appropriate treatment. Objective: To demonstrate the role of cardiac magnetic resonance imaging (CMR) in the assessment, diagnosis, and follow-up of cardiac fibroma. Case report: Female 21-year-old patient with a myocardial mass detected on echocardiogram. CMR confirmed a diagnosis of cardiac fibroma. The patient chose to be followed up, and her condition remained stable after six years. Discussion: Cardiac fibromas are the second most common neoplasm in children and young people. On CMR, it is characterized by intense and homogeneous delayed enhancement. CMR plays an important role in the assessment of cardiac masses.

A anomalia congênita das artérias coronárias (ACAA) é uma condição relativamente rara, que apresenta prevalência populacional estimada em 0,21% a 5,79%. 1 A ACAA apresenta amplo espectro de variações e pode ser classificada em anomalias de origem e trajeto, anomalias intrínsecas e anomalias de destino. 1,2 Dentro desse espectro da ACAA, a que se destaca pela maior prevalência, estimada em 0,3% a 0,8%, é a origem anômala da artéria circunflexa (ACx) no seio coronariano direito (SCD).

Atrial fibrillation is the most prevalent arrhythmia in clinical practice and has different strategies for its control. Of these strategies, the percutaneous ablation of the pulmonary veins stands out, with robust results in relation to drug treatment. It is an invasive procedure and, therefore, not free from complications, which must be properly diagnosed and treated. Among the possible complications, there is stiff atrium syndrome, characterized by reduced atrial compliance caused by post-ablation fibrosis, which, in turn, leads to atrial filling dysfunction and the consequent increase in atrial and venous capillary pulmonary pressures. The case report demonstrates this infrequent but important complication, which presents good results for clinical treatment, in addition to the contribution of cardiac magnetic resonance in its diagnosis and in the assessment of arrhythmia recurrence rates.
