Background: Multicenter studies conducted in developed countries demonstrated that custom-made devices are safe, effective, and durable for treating complex abdominal aneurysms. However, the situation in developing countries, such as Brazil, is different. Funding and time to have the endoprosthesis delivered are the major concerns. In order to overcome these conditions, high-volume Brazilian university hospitals started gaining experience with a custom-made device produced in the country.
Objective: The present study aimed to describe the practice of 2 tertiary centers and report the early results of fenestrated and branched endovascular repair of complex aortic aneurysms with a custom-made national device available in the Brazilian public health system.
Methods: Retrospective analysis of all consecutive patients that underwent fenestrated and branched endovascular aneurysm repair (F/BEVAR) of complex aortic aneurysms using custom-made manufactured endoprosthesis in 2 tertiary centers from January 2020 to July 2022.
Results: Thirteen cases were included (10 male, mean age 69 ± 9 years). 70% were complex abdominal aneurysms, and 30% were type II, III, and IV thoracoabdominal aneurysms (mean aneurysm diameter 69.2 ± 8.12 mm). F/BEVAR included 33 visceral arteries. The Apolo® device was used in all cases. Technical success was achieved in 12 out of 13 patients (92.3%). Thirty-day major adverse events included one death (7.7%), 5 acute renal failure (38.4%), 2 spinal cord ischemia (15.4%). The 1-year survival rate was 92.3%.
Conclusions: Fenestrated and branched endovascular repair of complex aortic aneurysms with the custom-made Apolo® device has proven safe and effective in high-volume tertiary centers in the Brazilian public health system. Considering the complexity of the cases, the early patency of vessels and low initial mortality support this device continuation and expansion to treat complex aortic aneurysms in a developing country.

This case report examines a rare cardiovascular abnormality, the Aberrant Aortic Origin of the Right Coronary Artery (AAORCA), in a 75-year-old patient with a history of myocardial infarction, acute renal injury, and cardiogenic shock. Rapid medical intervention, including coronary angioplasty, demonstrated the significance of prompt care. Chronic issues, including tobacco use and left ventricular dysfunction, complicated matters, emphasizing the importance of comprehensive long- term therapy.

Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.

Acute decompensated valvular disease encompasses a group of complex and challenging conditions, which are often the primary reason for admission to the cardiac intensive care unit and can also complicate the management of other primary cardiac disorders. Critically ill patients with valvular disease also present unique diagnostic and management challenges. Historically, medical and percutaneous interventional therapies have been limited and surgery was the only definitive treatment; however, surgical risk can at times be prohibitive.

Background The adoption of minimally invasive cardiac surgery (MICS) has increased over the past 25 to 30 years, driven by advancements in technology and a growing understanding of its benefits. This study evaluates the outcomes of 144 elective MICS procedures performed between January 2019 and September 2024. Methods Patients underwent various surgical approaches, including upper mini-sternotomy, mini-thoracotomy, and sub-xiphoid access.
