RESUMO
Messenger ribonucleic acid (mRNA) vaccines against coronavirus disease 2019 (COVID-19) are highly effective in preventing and decreasing disease severity, but the duration of the effect is attenuated over time and repeated vaccination is required. A 41-year-old Japanese male presented to our hospital with chest pain three days after receiving the third dose of the BNT162b2 mRNA vaccine. After various examinations, such as endomyocardial biopsy and viral polymerase chain reaction (PCR) testing of endomyocardial biopsy tissue, we made the diagnosis of acute myopericarditis associated with booster vaccination. Here, we report a rare case of myopericarditis after booster mRNA vaccination.
RESUMO
We herein report the case of a 79-year-old man who presented with right-sided heart failure (HF) 27 years after undergoing surgery for tetralogy of Fallot. The HF did not respond well to oral diuretics. Transthoracic echocardiography and chest X-ray failed to determine the cause of the HF for three years. An intrapericardial mass located just behind the sternum, was finally identified on computed tomography. The mass had compressed the right ventricle, causing right-sided HF. Pre-surgical diagnostic images led to suspicion of a chronic expanding intrapericardial hematoma (CEIH), and the CEIH was surgically removed. The patient's symptoms improved markedly.

A 49-year-old man was admitted to our hospital because of intermittent claudication and refractory hypertension 10 years after surgery to Stanford type A acute aortic dissection. He underwent total arch replacement with an elephant trunk of 22 mm in diameter. Transesophageal echocardiography revealed that distal end of the elephant trunk was stenosed. Systolic blood pressure gradient over this portion reached to more than 100 mmHg. Folding of elephant trunk and thrombus formation were considered to be the cause. Thoracic endovascular aortic repair relieved stenosis and intermittent claudication, and enabled better blood pressure control.
