Article Synopsis
  • The mitris valve combines features of two existing valves—the Carpentier-Edwards PERIMOUNT Magna Mitral Ease valve and INSPIRIS RESILIA tissue—for enhanced hemodynamic performance and durability.
  • Its design includes a more flexible, saddle-shaped sewing cuff that fits the mitral valve better, reducing risks of complications during double-valve replacements.
  • The valve also benefits from advanced technology that minimizes free aldehyde levels, suggesting improved long-term durability and reliability compared to earlier models.

Annuloplasty should always accompany mitral valve repair in order to achieve proper annular remodeling and stabilization. Numerous types of annuloplasty rings-that differ from rigid to semi-rigid and flexible devices, from complete to partial, and from flat to saddle-shaped rings-are clinically available. A deeper understanding of mitral valve function, in conjunction with several recent studies, suggest it is advisable to prefer annuloplasty rings that mimic the physiological mitral annulus shape and three-dimensional (3D) dynamic changes in order to reduce haemodynamic stress on valve components and optimize leaflet coaptation, perhaps improving valve repair durability too.

Aortic annuloplasty has been clearly demonstrated to have a protective influence in aortic valve repair. Over the past 20 years, different annuloplasty concepts have been proposed by different groups. However, the most appropriate approach to enable long-term annular stability remains highly controversial.

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.

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.

Cardiac myxoma is the most common primary benign cardiac tumor in adults and right atrial myxoma is a rare observation. We report a case of a 56-year-old woman who presented with dyspnea and diagnosed with a right atrial myxoma. Urgent operation through a right mini thoracotomy was done and myxoma was completely excised.

An indefinitely lasting bioprosthesis that does not require anticoagulation treatment is the holy grail of substitutive heart surgery. However, this goal is not yet in sight with the present state of technology. Over the past few years, tremendous advances have been achieved regarding tissue anticalcification processes, hemodynamic performance and future-proofing by ensuring compatibility with transcatheter valve-in-valve procedures.

Background: Acute mesenteric ischemia (AMI) after cardiac surgery is a rare but serious complication associated to high mortality. The time of onset is the key point to correctly evaluate the clinical scenarios.

Methods: Data from adult patients who underwent laparotomy for AMI after elective or urgent cardiac surgery were reviewed (January 2005 - December 2019) to report their anatomoclinical features in relationship to time of onset.

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.

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.

Surgical mitral valve reintervention is associated with significant morbidity and mortality, and repeat repair is not always feasible. We examine the clinical outcomes of the NeoChord procedure after failed conventional mitral valve repair. A total of 312 patients were treated with the NeoChord repair procedure between January 2014 and December 2018 at 5 European centers.

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.

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.

The original monograph on valvular prostheses in Surgical Technology International was published in 1993. It represents a milestone and a reference point for critically organizing information on a complex and rapidly evolving topic. The last update was published in 2010.

Background: Structural valve deterioration (SVD) is the Achilles' heel of bioprostheses. Its correlation with younger age is well known. In recent years we exclusively reserved use of small-size Mitroflow valve prostheses (LivaNova, London, United Kingdom) to an older patient population with small aortic annuli.

Objective: Hemostasis is a critical component of all surgical procedures and especially cardiac surgery. In addition to traditional means, topical hemostatic agents have been reported to be extremely effective in terminating bleeding during cardiac procedures. We compared a hemostatic matrix sealant agent (HEMOPATCH Baxter Healthcare Corporation, Deerfield, IL) with alternative topical hemostatic treatment in patients undergoing ascending aorta surgery with moderate bleeding.
