The differential diagnosis of aortic emergencies includes abdominal aortic aneurysms and aortic dissection. Aortic occlusion is another rare yet deadly vascular emergency to be wary of. For acute occlusions, definitive management by embolectomy or aortofemoral bypass must be performed promptly. When suspected because of the history and physical examination results, bedside ultrasonography rapidly confirms the diagnosis. We describe 2 very different cases of aortic occlusion both initially detected with bedside ultrasonography in our emergency department.

Effect of chronic total occlusion of coronary arteries on cardiovascular outcomes in patients undergoing transcatheter aortic valve replacement: A systematic review and meta-analysis.

Background: Transcatheter aortic valve replacement (TAVR) has significantly advanced the treatment of severe aortic stenosis (AS), particularly in elderly patients who often have coexisting coronary artery disease (CAD). Chronic total occlusion (CTO), a severe form of CAD, may negatively impact outcomes in TAVR patients, though data are limited. This meta-analysis aims to evaluate the impact of CTO on TAVR outcomes.

Objective: Half of re-interventions after fenestrated and branched endovascular aortic repair (FB-EVAR) are target vessel related. Regarding bridging stent choice, existing data are controversial. This meta-analysis aimed to evaluate the performance of Advanta V12/iCAST as bridging stent in FB-EVAR.

Transaortic endarterectomy (TE) is an effective and durable method of restoring patency in the aorta afflicted with atherosclerotic disease, which most commonly affects the infrarenal aorta and common iliac artery. When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.

An adherent placenta is a life-threatening condition that impairs the mother's life owing to hemorrhagic shock and disseminated intravascular coagulation. Profound hemorrhage resulting from placental abruption is often managed using hysterectomy to preserve the mother's life, although the consequent loss of fertility can be devastating, particularly in younger women. Thus, strategies that facilitate fertility preservation while effectively controlling hemorrhage should be considered viable alternatives.

Background: Since patients with congenital heart defects (CHD) frequently require life-long medical care and repeat invasive treatment, radiation exposure during interventional procedures is a relevant issue concerning potential radiation related risks. Therefore, an analysis on radiation data from the German Registry for Cardiac Operations and Interventions in patients with CHD was performed.
Methods: From January 2012 until December 2020 a total of 28,374 cardiac catheter interventions were recorded.
