Coronary fistula is a rare congenital heart disease. Usually it is diagnosed because of mild clinical event and sometimes detected by coronary angiography performed during acute phase of myocardial infarction. When the coronary fistula have an aneurysmatic form, it should be closed due to the risk of rupture and sudden death, especially when volumetric and pressure overload or coronary steal syndrome are present. The closure may be performed invasively or non-invasively; the latter method is prefered in asymptomatic patients.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Background: Isolated subsegmental pulmonary embolism (issPE) is a commonly encountered diagnosis. Although the International Classification of Diseases (ICD)-10 codes are used for research, their validity for identifying issPE is unknown. Moreover, issPE diagnosis is challenging, and the findings from radiology reports may conflict with those from expert radiologists.

Pancreaticojejunostomy (PJ) is a critical step in pancreaticoduodenectomy (PD), often complicated by the risk of postoperative pancreatic fistula (POPF). This video report demonstrates a novel robotic PJ technique employing a self-expandable metallic stent. The method involves the use of the Da Vinci Xi robotic system and the WallFlex™ Biliary RX Stent for improved anastomotic support, particularly in high-risk cases defined by soft pancreatic texture and narrow duct diameter (<3 mm).

Infective endocarditis (IE) is an infection that affects the heart valves, endocardium, and great vessels. It has a mortality rate of approximately 30% per year, so early diagnosis is essential to reduce morbidity and mortality. Cardiac angio-CT triggered by electrocardiogram (ECG) has been considered in IE management guidelines in recent years, given its high spatial resolution, contributing to the diagnosis and evaluation of valvular complications (vegetations, perforations, dysfunctions), perivalvular (abscesses, pseudoaneurysms, prosthesis dehiscence, fistulas) and compromised coronary arteries (embolism), allowing early diagnosis and treatment.
