Hoarseness Due to Aortic Arch Aneurysms
Conclusion: The surgical and interventional treatments offered similar hoarseness-relieving effects. Surgical or interventional treatment is warranted in such patients for both treatment of arch aneurysms and relief of hoarseness. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Saphenous Vein Vasa Vasorum as a Potential Target for Perivascular Fat-Derived Factors
Abstract Perivascular adipose tissue (PVAT) is a source of factors affecting vasomotor tone with the potential to play a role in the performance of saphenous vein (SV) bypass grafts. As these factors have been described as having constrictor or relaxant effects, they may be considered either beneficial or detrimental. The close proximity of PVAT to the adventitia provides an environment whereby adipose tissue-derived factors may affect the vasa vasorum, a microvascular network providing the vessel wall with oxygen and nutrients. Since medial ischaemia promotes aspects of graft occlusion the involvement of the PVAT/vasa vas...

The Global Burden of Rheumatic Heart Disease: Population-Related Differences (It is Not All the Same!)
Abstract Rheumatic heart disease (RHD) remains the most common cardiovascular disease in young adults and adolescents in need of heart surgery in low- and middle-income countries (LMICs). The mean age of patients is 20-25 years, often much younger. By contrast, the few patients with chronic RHD in developed countries present a mean age of around 55 years. It is absolutely fundamental to differentiate these two types of population. Pathology, lesions and surgical methods are different, and the results should not be compared. It is not all the same! A certain enthusiasm for mitral repair has recently surged, with several rep...

Comparison between Arch Zones in Modified Frozen Elephant Trunk Procedure for Complex Thoracic Aortic Diseases
Conclusion: FET procedure is a feasible repair technique in the treatment of complex aortic diseases, providing satisfactory early results. Because of its advantageous aspects, zone 0 fixation with debranching is the preferred technique in our clinic. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Preoperative Arterial and Venous Cannulation in Redo Cardiac Surgery: From the Safety and Cost-effectiveness Points of View
Conclusion: Venous and arterial cannulations before sternotomy decreased myocardial injury and complication rates, blood and blood product usage, hospital stay, and, consequently, hospital cos ts in our modest cohort. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Surgical ‘Safari’ vs. Educational Program: Experience with International Cardiac Surgery Missions in Nigeria
Conclusion: After these years of cardiac missions to our center, the experience of the local team, especially the surgeons, is far from desirable because each team visit usually lasted about a week or two and each team, with exception of the CardioStart International/William Novick Global Cardiac Alliance, adopted the surgical ‘ safari ’ method.

Heparin-coated vs. Non-coated Cardiopulmonary Bypass Circuits: Comparing Immediate Results with Different Target Activated Clotting Time
Conclusion: Heparin-coated circuits and reduced level of systemic heparinization with 300 seconds of target ACT level in cardiac surgery under CPB are safe and result in a very satisfactory clinical course. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Frailty Significantly Associated with a Risk for Mid-term Outcomes in Elderly Chronic Coronary Syndrome Patients: a Prospective Study
Conclusion: Being a frail elderly CCS patient is associated with worse outcomes. Therefore, frailty score should be evaluated for elderly CCS patients as a prognostic marker. (Source: Revista Brasileira de Cirurgia Cardiovascular)

The New Surface Landmarks for Blind Axillary Vein Puncture
Conclusion: We have developed a new blind approach to cannulate the axillary vein, which is as effective as the subclavian access, safer than that, and also allows to get this vein without the guidance of fluoroscopy, contrast, or echography. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Predictive Factors of Mortality in Acute Aortic Dissection and Validity of the EuroSCORE Algorithm in a Small-Sized Cardiac Surgery Institution
Conclusion: Female gender was the only independent predictor of operative mortality and survival in our institution. EuroSCORE is a poor scoring algorithm to predict mortality in AAD, but with consistent results fo r Penn Aa, Ab and Abc. (Source: Revista Brasileira de Cirurgia Cardiovascular)
