Objective: A crucial step in designing fenestrated stent grafts for treatment of complex aortic abdominal aneurysms is the accurate positioning of the fenestrations. The deployment of a fenestrated stent graft prototype in a patient-specific rigid aortic model can be used for design verification in vitro, but is time and human resources consuming. Numerical simulation (NS) of fenestrated stent graft deployment using the finite element analysis has recently been developed; the aim of this study was to compare the accuracy of fenestration positioning by NS and in vitro.

Background: Common femoral artery (CFA) stenting appears as a promising alternative treatment to the open surgery for de novo CFA stenosis. The stenting of lesions just located at the CFA is simple, whereas stenting of CFA bifurcation lesions is more complex, and outcomes are still matter of debate. The aim of this study was to describe and to compare clinical outcomes of techniques used to treat simple over complex lesions for the stenting of CFA lesions.

Objectives: With a focus on renal function, the goal of this multicentre study was to assess peri-operative complications and late mortality of open surgical repair (OSR) of juxtarenal abdominal aortic aneurysms (JRAAA).

Methods: From February 2005 to December 2015, 315 consecutive patients undergoing elective OSR of a JRAAA in five French academic centres were evaluated retrospectively. The definition of JRAAA was an aortic aneurysm extending up to but not involving the renal arteries, i.

Background: Although autogenous venous grafts are preferable for below-the-knee bypass surgery in patients with critical limb ischemia, some 20% of patients will have no suitable vein for grafting, compelling a resort to artificial graft materials. Retrospective subgroup analyses within published studies comparing heparin-bonded polytetrafluoroethylene (PTFE) with crude PFTE graft in below-the-knee bypass suggest that heparin-bonded graft offers superior long-term patency rates, but this has not been prospectively verified in patients with critical limb ischemia.

Methods: A single-blind randomized controlled trial in 20 French centers has been designed.

Background: The purpose of this study was to report our experience of treatment of aortic aneurysms using combination of renal and visceral arteries bypasses and fenestrated/branched stent graft in various complex anatomical situations.

Methods: Between November 2005 and March 2017, 10 patients underwent a hybrid strategy combining bypasses for renal and/or visceral arteries and custom-made fenestrated/branched stent grafts. Two patients had abdominal aortic aneurysm (1 juxtarenal and 1 suprarenal), and 8 patients had thoracoabdominal aortic aneurysm (1 type I, 2 type II including one dissection, 2 type III, 1 type IV, and 2 type V).

Objectives: The TECCO (Traitement des Lésions Athéromateuses de l'Artère Fémorale Commune par Technique Endovasculaire Versus Chirurgie Ouverte [Endovascular Versus Open Repair of the Common Femoral Artery]) trial is a randomized comparison of safety and efficacy of stenting versus open surgery for de novo common femoral artery (CFA) stenosis.

Background: Surgery for CFA lesions is considered effective and durable. Despite the widespread use of endovascular repair for infrainguinal disease, the value of this procedure for such lesions is uncertain.

An 81-year-old woman was referred for the treatment of a 79-mm-diameter short neck abdominal aortic aneurysm with highly tortuous iliac arteries. She was considered at high risk for open repair and not suitable for standard endovascular repair given the short length of the proximal neck. Delay for a manufactured custom-made fenestrated stent graft was too long given the diameter of the aneurysm.

Background: Kidney recipients are increasingly older with arterial disease and extended arterial calcifications. In a kidney transplantation population, the prognosis value of aortic and iliac calcifications remains poorly explored. We aimed to assess the impact of pretransplantation aortoiliac vascular calcifications on patients, grafts survival, and cardiovascular events.

Article Synopsis
  • The paper introduces an endoscopic expandable sizer designed for thoracoscopic aortic valve replacement using a sutureless prosthesis, allowing for dynamic sizing of the aortic annulus.
  • In experiments with ten aortic torsos, the feasibility of the sizing tool was confirmed, and subsequent successful implantation of sutureless valves was achieved.
  • The study concludes that the endoscopic expandable sizer is technically viable, with satisfactory valve size selection observed, although further testing with fluid dynamics is necessary before clinical trials.

Article Synopsis
  • Researchers developed a new testing method using bulge inflation and optical measurements to study the rupture properties of ascending thoracic aortic aneurysms (ATAAs), which are typically not covered by current literature.
  • The study analyzed data from 31 patients, finding that younger patients (under 55) had stronger tissues, and established that rupture occurs when the tissue reaches maximum extensibility.
  • The findings indicate that the risk of rupture is closely linked to the tissue's elastic modulus, regardless of patient age, aneurysm size, or aortic valve type, aiding in identifying patients at higher risk for surgical repair.

Article Synopsis
  • Minimally invasive aortic valve replacement usually requires small chest incisions, but this study introduces the first series of totally endoscopic aortic valve replacement (TEAVR) as a potential alternative.
  • Over two years, 14 patients underwent TEAVR successfully, with a high success rate of 92.8% for the thoracoscopic approach; only one needed conversion to traditional surgery.
  • The procedure was found to be safe, with no major complications or leakage, suggesting that TEAVR could be a viable option for low-risk patients, although further research is needed to improve the technique and patient outcomes.

Article Synopsis
  • * The heart team considered a transcatheter valve-in-valve method but chose to implant a sutureless 3f Enable valve instead, after removing the damaged leaflets.
  • * This surgical decision not only simplified the procedure but also resulted in excellent blood flow and heart function post-surgery during follow-up.

Article Synopsis
  • The study aims to determine the unique material properties of ascending thoracic aortic aneurysms (ATAA) by using preoperative dynamic gated CT scans of five patients who underwent surgery.
  • It involves minimizing two cost functions to align model predictions with actual CT measurements of the aneurysm volume, focusing on specific phases of the cardiac cycle.
  • The findings, validated through comparison of in vivo and in vitro tests, include finite-element stress analyses that indicate the method shows promise in estimating rupture risk for individual patients based on their unique aneurysm properties.

We present a technique of mitral valve surgery performed in a patient with severe pectus excavatum and previous Bentall surgery. Neither redo sternotomy nor conventional right minithoracotomy were thought to provide adequate surgical access to the mitral valve. We therefore opted for a combined procedure comprising sternal reconstruction and right minithoracotomy mitral valve replacement.

Background: Recently, sutureless aortic bioprostheses have been increasingly adopted to facilitate minimally invasive aortic valve replacement. We aimed at evaluating the impact of the transition from conventional bioprostheses to the routine use of the 3f Enable prosthesis (Medtronic ATS Medical, Minneapolis, MN) for aortic valve replacement through ministernotomy.

Methods: Between November 2009 and November 2012, 83 consecutive minimally invasive aortic valve replacement procedures were performed in our institution by the same surgeon through an upper T-shaped ministernotomy.

We report the first case of a successful transapical transcatheter treatment of a giant pseudoaneurysm originating from a rupture of the mitroaortic fibrosa that occurred 3 months after a Bentall procedure in a 81-year-old male patient. Because of the age of the patient and the location of the leak at the mitroaortic fibrosa, the risk of a conventional ascending aorta reoperation was considered too high, and a transcatheter approach was chosen. A transapical puncture was performed with a left minithoracotomy followed by a catheterization of the pseudoaneurysm neck and an 8-mm Amplatzer (St.
