Hybrid repair of aortic aneurysm in a patient with a congenital pelvic kidney.

We describe a patient with an asymptomatic infrarenal abdominal aortic aneurysm. Treatment decisions were complicated by the presence of a left congenital pelvic kidney supplied by two renal arteries originating from the proximal common iliac arteries bilaterally and respiratory status that was prohibitive to open repair. A hybrid surgical repair was performed with a bifurcated aortic endograft and parallel grafting to revascularize the pelvic renal arteries.

Renal artery (RA) anomaly is common and may have significant clinical implications. We present a case of a 29-year-old man in whom the upper two-thirds of the right kidney were supplied by the right internal mammary artery and collateral network. Additionally, the superior left RA had proximal stenosis with a distal aneurysm.

Right ventricular myocardial infarction (RVMI) is a significant and distinct form of acute myocardial infarction associated with considerable morbidity and mortality. It occurs most commonly due to proximal right coronary artery obstruction, often in conjunction with inferior myocardial infarction. RVMI poses unique diagnostic and therapeutic challenges due to the anatomical and functional differences between the right and left ventricles.

This study aims to evaluate the implementation of concomitant CAD assessment on pre-TAVI (transcatheter aortic valve implantation) planning CTA (CT angiography) aided by CT-FFR (CT-fractional flow reserve) [The CT2TAVI protocol] and investigates the incremental value of CT-FFR to coronary CT angiography (CCTA) alone in the evaluation of patients undergoing CT2TAVI. This is a prospective observational real-world cohort study at an academic health system on consecutive patients who underwent CTA for TAVI planning from 1/2021 to 6/2022. This represented a transition period in our health system, from not formally reporting CAD on pre-TAVI planning CTA (Group A) to routinely reporting CAD on pre-TAVI CTA (Group B; CT2TAVI protocol).

Objective: The aim of this study was to perform a comparative pre-clinical evaluation of a new fenestrated endovascular aneurysm repair dedicated stent using perfused 3D printed patient anatomies.
Methods: The test setup included a pulsatile pump set to reproduce human haemodynamics, four 3D printed pararenal aneurysms connected to a bench test, and four corresponding fenestrated grafts (Zenith Fenestrated; Cook, Bloomington, IN, USA). Bridging stents were sized based on analysis of patients computed tomography scans and included either four standard covered stents (BeGraft [BG]; Bentley, Hechingen, Germany) or four similar covered stent grafts mounted on a modified balloon to allow stent implantation and flaring in one step (BeFlared [BF]; Bentley).
