Energetic matrix metalloproteinase-8 (aMMP-8) point-of-care check (POCT) in the COVID-19 outbreak.
Myxomas account for a majority of the reported primary cardiac tumors that are relatively rare, and biatrial myxomas in an atrial septal defect are extremely rare. Here, we present the case of a healthy 79-year-old woman who was referred to our hospital after a giant mass in the left atrium was incidentally detected by transthoracic echocardiography. Although she was asymptomatic, we surgically resected the mass soon after admission, considering the risk of embolism. read more During the surgery, we observed the giant bilateral tumor in an atrial septal defect, which was, on pathological evaluation, found to be a myxoma. .It is still difficult to treat acute limb ischemia (ALI) in the non-stenting zone such as the popliteal artery. We describe a temporary endoluminal bypass technique for ALI in the non-stenting zone using a guide extension catheter. An 83-year-old female was admitted and diagnosed with ALI in her left leg. The angiogram showed a thrombotic obstruction of the left popliteal artery. Aspiration and dilation by angioplasty could not revascularize. Although Fogarty thrombectomy can be applicable, we avoided it because of its risk of complications and performed a temporary endoluminal bypass technique. After evaluating the occluded lesion by intravascular ultrasound, we delivered a guide extension catheter to fully cover it. Because it played the role of an endoluminal bypass, the blood flow to the distal tibial arteries could be confirmed in the angiogram. A thrombolytic drug was administered intra-arterially for the whole day, and the angiogram showed a reduction of the thrombus on postoperative day (POD) 1. On POD 2, the blood flow was maintained without flow limitation even after removing the catheter. Finally, she was discharged without any complications. This technique might be an alternative in cases of failed conventional treatments for ALI although further investigation needs to be undertaken. .A 53-year-old woman was referred to our hospital with acute coronary syndrome. The coronary angiography demonstrated a single coronary artery. Culprit lesion was a subtotal occlusion of the proximal left anterior descending coronary artery, which was recanalized and treated with drug-coated balloon angioplasty. The patient recovered quickly after the procedure. A coronary computed tomography angiography visualized the left main coronary artery, which was passing between the ascending aorta and the pulmonary trunk and categorized this anomaly as R-II-B according to Lipton's classification, representing an extremely rare coronary anomaly. .Venous thromboembolism (VTE) and arterial thromboembolism (ATE) are frequent complications in cancer patients. For curative treatment of VTE in a neoplastic context, recent randomized controlled trials and meta-analyses suggest that direct oral anticoagulants (DOACs) can be an alternative to conventional treatment by low molecular weight heparins (LMWHs). On the other hand, the role of DOACs in the treatment of cancer-related ATE remains unclear. Here, we report a case of stroke recurrence in a patient initially treated with DOACs that were started for cancer-related VTE. The failure of the DOACs, compared to LMWHs, to prevent the stroke recurrence led us to the infrequent final diagnosis of nonbacterial thrombotic endocarditis (formerly known as marantic endocarditis). This case illustrates the association between ATE and VTE in a patient with marantic endocarditis related to lung cancer and recurrence of ischemic stroke on direct oral anticoagulant therapy. .Ascending aortic pseudoaneurysms following open-heart surgery are treated by redo surgery or endovascular therapy when surgical risks are high. Extreme variations in their morphology, proximity to coronary and arch branches and vascular access may vary the timing, strategy, device choice, and technique in each patient. Three patients with varying etiology, presentations, and morphology of the pseudoaneurysms underwent successful endovascular exclusion by individually tailored strategies. The approach includes optimal treatment of the underlying infections before the endovascular intervention despite the emergency to treat the condition; choosing appropriate device depending on the proximity to aortic branches, choosing appropriate access depending on the angulation of the entry of pseudoaneurysm to the aortic lumen, and use of adequate imaging for achieving procedural success. .Stellate ganglion block is useful as emergency therapy in patients with ventricular tachycardia storm but is limited due to low availability of experienced teams in the condition of intensive care units. This method used urgently reduced life-threatening ventricular tachycardia when conservative and interventional methods were ineffective. .Cystic echinococcosis (CE) or hydatid disease is a zoonosis caused by ingestion of the eggs of the tapeworm Echinococcus granulosus. Larger cysts can cause symptoms by compressing surrounding tissues. Large cysts can also rupture and cause sudden onset of cough, fever, hypersensitivity reactions, and massive hemoptysis. We report a case of hydatid cyst, which caused massive hemoptysis after an urgent percutaneous coronary intervention and was successfully controlled with bronchial artery embolization. .Atrial function is a key factor in cardiac output and oxygen consumption (VO2). Substantial improvements in VO2 have been reported after restoring sinus rhythm (SR) in patients with atrial fibrillation. However, there are no published data on how atrial function affects VO2 in patients with both constrictive pericarditis (CP) and severe mitral stenosis (MS). A 53-year-old caucasian patient consulted for exacerbated heart failure (EHF). His medical record lists ischemic heart disease, severe MS, and CP after thoracic radiotherapy. The electrocardiogram showed atrial flutter (AFL) with controlled ventricular rate. Normal left ventricular ejection fraction was observed. Ergospirometry showed an impaired maximum VO2 (VO2 max) of 6 ml/kg/min. On the electrophysiological study typical AFL was diagnosed and ablated achieving a great exercise capacity improvement, correlated with an increase of VO2 max to 16 ml/kg/min a week after ablation, and disappearance of EHF symptoms. This case illustrates how restoration of SR resulted in a clinical substantial improvement.
