Aortic Valve Replacement Via Right Anterior Mini-Thoracotomy: the Conventional Procedure Performed Through a Smaller Incision
Abstract Minimally invasive aortic valve replacement has gained consent due to its good results in terms of minimized surgical trauma, faster rehabilitation, pain control and patient compliance. In our experience, we have tried to replicate the conventional and gold standard approach through a smaller incision. Sparing the right internal thoracic artery, avoiding rib fractures and performing total central cannulation is important to make this procedure minimally invasive from a biological point of view too. In addition, the total central cannulation is pivotal to simplify perfusion and drainage. Moreover, a complete step-b...

We presented a case of a 56-year-old man with giant pulmonary artery aneurysm caused by a misdiagnosed patent ductus arteriosus, severe multivalvular disease and active aortic valve endocarditis successfully treated by surgery. The correct diagnosis was missed despite preoperative diagnostics because the small patent ductus arteriosus was located at the distal part of common pulmonary trunk and a huge regurgitant signal overlapped its Doppler signal. Thorough evaluation of every patient, regardless of age, is necessary to recognize and treat this congenital anomaly. (Source: Revista Brasileira de Cirurgia Cardiovascular)

Robotic Cardiac Surgery in Colombia: Overcoming the Challenges of a Middle-income Setting
Abstract In developing countries, limited resources and low health budgets result in slow developments in the field of cardiac surgery.

Despite the challenges, efforts to overcome these hurdles are critical for the future of cardiac surgery in low-income settings.

This new method proposes a modification in the anastomosis of the superior vena cava aiming to pre-serve donor ’ s right ventricular function by decompressing the pulmonary territory and reducing the pulmonary arterial pressure, as a biological ventricular assist device. Finally, a second intervention is proposed, where a “ twist ” is performed to place the donor ’ s hear...

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...
