Evolution over time of aortic root anatomy after aortic valve reimplantation.

Objective: Restoring the anatomic relationships among the aortic root components is important to achieve durable valve competence. We previously analyzed the in vivo anatomy of the aortic root after reimplantation with the Valsalva graft. This study aims to evaluate if the topographic relationship among the neoroot components varies over time.

Aortic valve repair with annuloplasty.

Objectives: Aortic valve repair procedures for aortic valve regurgitation have been progressively adopted in the last decades. We analysed our results with an external ring annuloplasty and/or leaflet repair.

Methods: From April 2014 to December 2023, 61 consecutive patients underwent aortic valve repair with external Teflon ring annuloplasty.

Different Oxidative Stress and Inflammation Patterns of Diseased Left Anterior Descending Coronary Artery versus Internal Thoracic Artery.

Background: Oxidative stress and inflammation are typically implied in atherosclerosis pathogenesis and progression, especially in coronary artery disease (CAD). Our objective was to investigate the oxidative stress and inflammation burden directly associated with atherosclerotic plaque in patients with stable coronary disease undergoing coronary artery bypass graft (CABG) surgery. Specifically, markers of oxidative stress and inflammation were compared in blood samples obtained from the atherosclerotic left anterior descending artery (LAD) and blood samples obtained from the healthy left internal thoracic artery (LITA), used as a bypass graft, within the same patient.

Temporary intravascular shunts and limb salvage in civilian vascular trauma.

Background: Temporary intravascular shunts (TIVS) may allow quick revascularization and distal reperfusion, reducing the ischemic time (IT) when an arterial injury occurs. Furthermore, TIVS temporarily restore peripheral perfusion during the treatment of concomitant life-threatening injuries or when patients require evacuation to a higher level of care. Notwithstanding, there are still disputes regarding the use of TIVS, in view of the paucity of evidence in terms of potential benefits and with regard to the anticoagulation during the procedure.

Twenty-year experience of aortic valve reimplantation using the Valsalva graft.

Objectives: Over the past 20 years, valve-sparing aortic root replacement has aroused increasing interest because of a progressive attitude towards the preservation of natural tissue. Aortic reimplantation is the most used technique to spare the valve, allowing simultaneously aortic root replacement and aortic annular stabilization. The reimplantation into a graft with sinuses guarantees an optimal anatomic and functional reconstruction with established good results at 15 years.

Mitral repair of myxomatous valves with simple annuloplasty: a follow-up up to 12 years.

Objectives: Diffuse myxomatous mitral valve degeneration (DMD) represents a challenge in the reparative mitral valve surgery. A subgroup of patients with symmetrical DMD can be effectively treated with a simple band-annuloplasty with good early and mid-term results. Here, we evaluate the long-term outcomes in terms of freedom from reoperation, recurrence of moderate or severe mitral regurgitation (MR) and overall survival.

Reimplantation versus aortic ring annuloplasty in bicuspid valve with borderline aortic root ectasia.

Objective: Bicuspid aortic valve repair can be achieved with the reimplantation technique or external ring annuloplasty. Reimplantation could be an "overtreatment" in nonaneurysmatic aortic roots. External ring repair, on the contrary, could be an "undertreatment" in dilated roots.

Root Reimplantation and Aortic Annuloplasty With External Ring in Bicuspid Aortic Valve: An Anatomical Comparison.

Aortic annuloplasty has demonstrated to be a protective factor in valve-sparing root replacement and aortic valve repair. Both reimplantation for aortic root aneurysms and external ring annuloplasty for isolated aortic regurgitation have demonstrated good long-term results. The aim of this anatomical study is to compare aortic reimplantation with Valsalva graft with aortic external ring annuloplasty in bicuspid aortic valves, analyzing their morphological features with CT scan.

Aortic root anatomy after aortic valve reimplantation.

Objective: During the last decade, special concerns have been raised about the anatomic relationships among the sinotubular junction, ventricular-aortic junction, and virtual basal ring to improve the results of root reconstruction. The aim of this study is to evaluate the in vivo anatomy of the aortic root after reimplantation with the Valsalva graft and the anatomic relationship between its components.

Methods: We analyzed 10 consecutive patients with tricuspid aortic valves who underwent reimplantation with the Valsalva graft between September and December 2019.

Optimized Use of the "Skirt" of the Valsalva Graft for the Completion Bentall Procedure.

This report discusses the case of a patient with an aortic root aneurysm who had previously undergone aortic valve replacement with a large mechanical prosthesis that proved to be normally functioning at the time of reoperation. This report describes a technique of replacing the aortic root while retaining the existing aortic valve, similar to the completion Bentall procedure, using a 32-mm Valsalva graft by suturing the skirted portion of the graft to the sewing ring of the mechanical valve. The ability of the skirt to increase its diameter is the key to this approach.

Long-term follow-up of Bentall procedure using the Perimount bioprosthesis and the Valsalva graft.

Objectives: Bentall procedure is the gold standard for aortic root pathologies when valve repair is not feasible. The development of durable bioprosthetic valves and improved vascular conduits allowed the implementation of bioprosthetic composite grafts; hereby, we performed a retrospective analysis of long-term follow-up of Bentall procedure using the Valsalva graft and the Perimount Magna Ease prosthesis.

Methods: From June 2000 to March 2019, 309 patients received an aortic root and valve replacement with a bioprosthetic composite graft.

External Stents for Vein Grafts in Coronary Artery Bypass Grafting: Targeting Intimal Hyperplasia.

Introduction: Progressive saphenous vein graft (SVG) failure remains a key limitation to the long-term success of coronary artery bypass grafting (CABG). SVG disease after the first year is dominated by intimal hyperplasia, which predisposes the SVG to thrombosis and accelerated atherosclerosis. The objective of this study was to review and summarize the latest experimental and clinical data on the use of mechanical external stents for vein grafts.

A direct correlation between commissural orientation and annular shape in bicuspid aortic valves: a new anatomical and computed tomography classification.

Objectives: The shape of the aortic annulus is still under debate. Recent findings suggest a possible gradual spectrum of circularity from tricuspid aortic valves (TAVs), to type 1 bicuspid aortic valves (BAVs) to type 0 BAVs. BAVs have been recently classified in a symmetrical (type A), asymmetrical (type B) or very asymmetrical (type C) phenotype according to the commissural orientation (CO) (160°-180°, 140°-159° and 120°-139°, respectively).

Ascending aorta disruption after thoracic blunt trauma.

Blunt traumatic aortic injury is the second leading cause of death after motor vehicle accidents. The most frequent localisation of aortic lesion is the isthmus, especially in those who survived the accident. Here we report a case of blunt traumatic aortic injury with unusual localisation and modality.

One-Year Outcomes after Ruptured Abdominal Aortic Aneurysms Repair: Is Endovascular Aortic Repair the Best Choice? A Single-Center Experience.

Background: Treatment of ruptured abdominal aortic aneurysms (rAAAs) is still burdened by high morbidity and mortality. Although endovascular aortic repair (EVAR) offers encouraging results in elective setting, its role as first-line strategy to treat rAAA is still debated. Our aim was to compare early and late outcomes in patients undergoing open surgical repair (OSR) versus EVAR for rAAAs.

Therapeutical Options in the Management of Carotid Dissection.

Background: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study, we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD.

Methods: From February 2006 to February 2016, 44 patients (28 women and 16 men, age range 25-65 years, mean 42) with CAD were included in this study.

Extra-anatomical bypass: a surgical option for recurrent aortic coarctation.

Background. Balloon aortoplasty with or without stenting is a less invasive alternative to open surgery for the management of recurrent isthmic coarctation. However, in patients with previous small size tube graft, an open surgical correction is mandatory and, in most cases, an anatomical aortic reconstruction is carried out.

Mid- and long-term results of endovascular treatment in thoracic aorta blunt trauma.

Study Aim: Evaluation of results in blunt injury of the thoracic aorta (BAI) endovascular treatment.

Materials And Methods: Sixteen patients were treated for BAI. Thirteen patients had associated polytrauma, 4 of these had a serious hypotensive status and 4 had an hemothorax.
