RESUMEN
Hypereosinophilic syndrome is a heterogeneous group of disorders, the majority of which are idiopathic. Cardiac manifestations, particularly eosinophilic myocarditis and endomyocardial fibrosis, are a typical course of morbidity and mortality in hypereosinophilic syndrome. We present a case of a patient with asthma and idiopathic eosinophilia who presented with dyspnea and edema. Cardiac ultrasonography showed pericardial effusion and reduced left ventricular motion, which persisted despite heart failure therapy, although pulmonary congestion improved. The peripheral blood eosinophil count was markedly elevated four days after admission, even though eosinophilia was not present at admission. Parasitic disease, autoimmune disease, and drug-induced cardiomyopathy were excluded as possibilities. A high dose of steroid therapy was started due to eosinophilic myocarditis. Cardiac function improved soon after therapy, along with a reduction in eosinophils. Upon retrospective examination, cardiomegaly and low voltage were observed, along with an elevation in the eosinophil count 15 months before admission. Monitoring chest radiography and electrocardiograms according to fluctuations in eosinophils may enable early detection and treatment of cardiac involvement in patients with hypereosinophilic syndrome, as demonstrated by this case.
RESUMEN
Percutaneous endovascular treatment of peripheral vascular disease with small-caliber short sheaths may lead to device removal difficulties. A 50-year-old woman on hemodialysis underwent endovascular intervention for right common femoral artery stenosis, via the right brachial artery. A 4-Fr short sheath was used for the procedure owing to a previous hematoma at the puncture site. However, the balloon catheter could not cross the calcified lesion and was difficult to remove. A microcatheter was inserted and withdrawn, but the guidewire was kinked and could not be retrieved. Surgical retrieval of the guidewire and balloon catheter was performed. The kinked guidewire and microcatheter had migrated outside the vessel. In peripheral vascular intervention, the use of a long sheath in the brachial artery approach is important. Forcible removal of a difficult-to-remove catheter may cause further vascular damage. Therefore, it is essential to stop immediately and consider surgical treatment.
RESUMEN
The subject was a 70 year-old man who survived for 31 years after being diagnosed with right ventricular cardiomyopathy, having undergone right ventricular (RV) aneurysmectomy at the age of 39. His arrhythmia and syncopal attacks were effectively abolished after the original aneurysmectomy. Although he frequently suffered from right heart failure, hemodialysis improved his status. However, the patient died due to worsening anasarca caused by RV low output syndrome. Autopsy results indicated extensive replacement of the RV myocardium with fibrous and fatty tissues. This case suggests that patients with arrhythmogenic RV cardiomyopathy, but without left ventricular abnormalities and rapid ventricular arrhythmia, have a relatively favorable prognosis, although RV abnormalities may be progressive.
