Abstract Pulmonary endarterectomy is a curative procedure for chronic thromboembolic Pulmonary Hypertension. As usual, cardiopulmonary bypass circuit is required. However, there are several complications attributed to extracorporeal circulation. Hemodilution, systemic inflammatory response syndrome and leukocyte sequestration are circulation related complications. The severe forms include Acute Respiratory Distress Syndrome, Acute Lung Injury, myocardial stunning, dysfunction of the right ventricle, coagulopathy, postoperative stroke or renal dysfunction.

Appropriate Surgical Repair of Ventricular Free Wall Rupture after Infarction: a Case Report
Abstract Ventricular free wall rupture is a fatal mechanical complication of acute myocardial infarction. In some cases it can be represented as subacute clinic and may not cause death in a few minutes. Acute pseudo-aneurysms are extremely unstable and bound to fatal rupture. Herein we report a male patient who suffered dyspnea and mild chest pain, 4 weeks after acute ST-segment elevation myocardial infarction. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Hybrid Treatment of Complex Aortic Arch Anomaly with Saccular Aneurysm
Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Endovascular Treatment of the Ascending Aorta: is this the Last Frontier in Aortic Surgery?
Abstract Regardless the successful treatment of the descending aorta with endovascular prosthesis, for the ascending aorta segment, because of several anatomic and physiologic issues, this technique has been considered an alternative only for high-risk or inoperable patients. Despite restricted indications, hundreds of treatments have been performed worldwide, demonstrating its safety and reproducibility if it is done in high-quality centers. Therefore, understanding patients ’ selection criteria and technique limitations are critical to its application. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Heyde Syndrome Treated by Conventional Aortic Valve Replacement
We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy. (Source: Revis...

Adverse events such as acute lung injury, postimplantation syndrome, and death are associated with an elevated IL-6 level. Thus, circulating IL-6 could be a reliable biomarker for the diagnosis of AD and for the eveluation of the therapeutic outcomes and the prognosis of AD patients.
