During the COVID-19 pandemic, many specialists doctors found themselves in a situation that they had not faced for a long time: treating patients out of their subarea of expertise. The possibilities of teaching and learning through the modalities of webinars brought to these days the urgent necessity for teamwork and interdisciplinary approach, taking advantage of different areas of expertise to the same patient. With the amount of papers published and the speed at which data are accessed, and analyzed it is impossible to be aware of new findings in all medical areas. The lesson that the COVID-19 pandemic brought to us was the urgent need for the interdisciplinary approach to treating better our patients, and not only each disease they present with. We must review our traditional approach to medical students, residents, colleagues, and patients in which we became stuck to distance and time obstacles. We must use the technology on our behalf to offer the best treatment and follow-up for patients. We live now in the Medicine 4.0 era. As Darwin a long time ago proved: we must evolve!

In December 2019, the novel coronavirus disease 2019 (COVID-19) emerged in China and spread rapidly around the world, resulting in a pandemic declared by the World Health Organization in March 2020. The disease has affected more than 11 million people in Brazil, with more than 265.000 deaths to date, as we are now facing a second wave of infections. Regarding medical assistance and training, it turned out to be a great challenge, since - among other things - many residents were relocated to respiratory units to treat patients with COVID-19. Even though the residency programs situation has become chaotic all around the world and the activities in almost all specialties nearly stopped (especially in surgical specialties), the need to reinvent the way of teaching was the best concern. Worldwide the “webinars fever” was an impulse to try new strategies to fulfill the gaps of knowledge of these future specialists. It is crucial to call to the responsibility put on medical training institutions to prepare these new professionals according the principles of evidence-based medicine, surgical proficiency and patient safety.

We present an unusual case of a 67-year-old woman with an incidental finding of a cardiac mass on a chest-computed tomography. Coronary angiotomography confirmed the diagnosis of a right coronary artery aneurysm, with 5.7x5.7 cm. Patient underwent aneurysm resection and coronary artery bypass graft surgery, with subsequent histologic study suggestive of arteritis sequela. Patients with giant coronary artery aneurysms are at high risk of complications and must benefit from aneurysm exclusion. This is a rare condition that can also be part of a systemic inflammatory disease.
