Objectives: The aim of this study was to describe trends and outcomes for patients undergoing surgical aortic valve replacement (SAVR) in the Netherlands.
Methods: The Netherlands Heart Registration database was used to report the number and outcomes of isolated, primary SAVR procedures performed from 2007 to 2018 in adult patients.
Results: A total of 17 142 procedures were included, of which 77.
Background: The foramen of Winslow is the opening between the peritoneum and the omental bursa just caudal to the liver and dorsal to the lesser omentum. Internal herniation of the intestine through the foramen of Winslow can cause acute abdominal pain.
Case Description: A 45-year old man without relevant medical history presented with acute abdominal pain.
Objective: To describe the trends in management and outcomes of patients with acute type B aortic dissection in the International Registry of Acute Aortic Dissection.
Methods: From 1996 - 2022, 3 908 patients were divided into similar sized quartiles (T1, T2, T3, and T4). In hospital outcomes were analysed for each quartile.
Objective: Effectiveness of thoracic endovascular aortic repair in type B aortic dissection is impaired by persistent retrograde false lumen flow via distal re-entry tears. Controlled, stentgraft-assisted balloon dilatation of the true lumen at its lower end, or Knickerbocker technique, may block retrograde false lumen flow and consequently improve effectiveness by inducing immediate thrombosis along the entire descending thoracic aorta.
Materials And Methods: A single-center retrospective analysis was performed for all consecutive patients with aortic dissection treated with the Knickerbocker technique to block retrograde false lumen flow.
Objective: To describe mid-term outcomes of the use of EndoAnchors as an adjunct for arch and thoracic endovascular aortic repair (TEVAR).
Methods: A retrospective multicentre series from nine centres using the Heli-FX EndoAnchor System (Medtronic Inc, Minneapolis, USA) at TEVAR over May 2014-May 2019 is presented. The study is registered at ClinicalTrials.
Article Synopsis
- This study examines the long-term success rates of surgical revascularization of the left subclavian artery (LSA) when done alongside thoracic endovascular aortic repairs in patients without arterial occlusive disease.
- The research included 90 patients, primarily male and averaging 66 years old, who underwent LSA bypass or transposition between 2000 and 2017, focusing on their outcomes at various follow-up points.
- Results showed a high patency rate, with 97% freedom from occlusion and 90% freedom from severe stenosis over a mid- to long-term follow-up period.
Objectives: The aim of this study was to evaluate the effects of the coronavirus 2019 pandemic on elective and acute thoracic aortic surgery in the Netherlands.
Methods: The Netherlands Heart Registration database was used to compare the volume of elective and acute surgery on the thoracic aorta in 2019 and 2020, starting from week 11 in both years. A sub-analysis was done to assess the impact of the pandemic on high-volume and low-volume aortic centres.
Objective: To evaluate the efficacy of thoracic endovascular aortic repair (TEVAR) in the treatment of patients with complicated type B aortic intramural haematoma (IMH).
Methods: A retrospective observational study of patients treated between January 2002 and December 2017 was performed. Complicated type B IMH was defined as persistent pain, rapid dilatation, presence of ulcer-like projections (ULPs), haemothorax, and other signs of (impending) rupture.
Objectives: The aim of this study was to evaluate the short- to mid-term outcomes of descending thoracic aortic aneurysm (DTAA) repair from the Gore Global Registry for Endovascular Aortic Treatment (GREAT).
Methods: This is a multicentre sponsored prospective observational cohort registry. The study population comprised those treated for DTAA receiving GORE thoracic aortic devices for DTAA repair between August 2010 and October 2016.
Thoraflex hybrid as frozen elephant trunk in chronic, residual type A and chronic type B aortic dissection.
Interact Cardiovasc Thorac Surg
April 2021
Objectives: The frozen elephant trunk technique is an increasingly common treatment for extensive disease of the thoracic aorta. The objective of the study was to evaluate the outcomes of frozen elephant trunk specifically in chronic (residual) aortic dissections, focusing on downstream aortic remodelling.
Methods: Between 2013 and 2019, a total of 28 patients were treated using the Vascutek Thoraflex hybrid graft at our institution for chronic dissections/post-dissection aneurysms.
Purpose: To describe steps related to intraoperative C-arm orientations that can be taken during preoperative planning of thoracic stent-graft repair to facilitate the deployment of EndoAnchors in the distal aortic arch.
Technique: Previous experience from transcatheter aortic valve implantation (TAVI) may be helpful in addressing issues with C-arm orientation. In TAVI, preoperative computed tomography (CT) images are routinely obtained to generate a patient-specific curve that represents a virtually complete rotation of the C-arm perpendicular to the annulus.
Objective: The Global Registry for Endovascular Aortic Treatment (GREAT), a retrospective sponsored registry, was queried to determine the incidence and identify potential predictors of access related complications after TEVAR.
Methods: This is a multicentre, observational cohort study. For the current study, all patients were treated only with the Conformable GORE® TAG® Thoracic Endoprosthesis and GORE® TAG® Thoracic Endoprosthesis devices for any kind of thoracic aortic disease.
Objective: Tortuosity in the descending thoracic aorta (DTA) comes with aging and increases the risk of endoleaks after TEVAR. With this report, we would like to define and classify tortuosity in the DTA of patients with thoracic aortic disease.
Methods: Retrospective case-control study of two hundred seven patients, comparing sixty-nine controls without aortic disease (CG), to sixty-nine patients with descending thoracic aortic aneurysm (AG) and sixty-nine patients with type B aortic dissection (DG).
Background: Understanding morphological changes of ascending aorta, aortic arch and descending aorta with cardiac and respiratory motion is critical for planning of endovascular repair of thoracic aorta. The aim of this study was to determine the impact of the cardiac cycle on thoracic aortic geometry.
Methods: In this retrospective study, electrocardiogram-gated cardiac computed tomography from 116 patients who were evaluated for transcatheter aortic valve replacement were reviewed.
Background: Complications after thoracic endovascular aortic repair (TEVAR) are common. Even after a successful TEVAR, a late endoleak (>30 days) can occur. The objective of this study is to summarize the current evidence and, if lacking, the need of evidence regarding the incidence and predictive factors for type 1b endoleak in patients with aortic aneurysm treated with TEVAR.

Methods And Results: Two groups of hundred patients < 65 years and hundred patients ≥ 65 years, with no vascular diseases were made.
Objective: To analyze presentation, management, and outcomes of acute aortic dissections with proximal entry tear in the arch.
Methods: Patients enrolled in the International Registry of Acute Aortic Dissection and entry tear in the arch were classified into 2 groups: arch A (retrograde extension into the ascending aorta with or without antegrade extension) and arch B (only antegrade extension into the descending aorta or further distally). Presentation, management, and in-hospital outcomes of the 2 groups were compared.

Patients with Marfan syndrome presented at a significantly younger age compared to patients without Marfan syndrome (38.2±13.
View Article and Find Full Text PDFObjectives: Thoracic endovascular aortic repair (TEVAR) has been shown to lead to increased aortic stiffness. The aim of this study was to investigate the effect of stent graft type and stent graft length on aortic stiffness in a controlled, experimental setting.
Methods: Twenty porcine thoracic aortas were connected to a pulsatile mock loop system.
Objective: The objective of this study was to describe our experience with endovascular aneurysm repair (EVAR) with the use of chimney grafts for branch vessel preservation.
Methods: Patients treated with a chimney graft procedure between October 2009 and May 2015 were included for analysis. Patients who were not considered eligible for open surgical repair or for conventional, branched, or fenestrated endovascular repair were selected.
Background: Aortic stiffness is an independent predictor of cardiovascular mortality. In this study, the effect of thoracic endovascular aortic repair (TEVAR) on aortic stiffness is investigated by measuring aortic pulse wave velocity (PWV) in an ex vivo porcine model.
Methods: Fifteen fresh porcine thoracic aortas were connected to a benchtop pulsatile system.
Objectives: To quantify the impact of thoracic endovascular aortic repair (TEVAR) on radial aortic strain with the aim of elucidating stent-graft-induced stiffening and complications.
Methods: Twenty fresh thoracic porcine aortas were connected to a mock circulatory loop driven by a centrifugal flow pump. A high-definition camera captured diameters at five different pressure levels (100, 120, 140, 160, and 180 mmHg), before and after TEVAR.
