Sutureless aortic bioprosthesis valve implantation and bicuspid valve anatomy: an unsolved dilemma?

Interest is growing in the clinical use of sutureless (SU) valves. However, indications in some anatomical sub-settings, like bicuspid aortic valves (BAV), have been so far limited. We discuss herein our initial experience with the implantation of the 3f Enable SU bioprosthesis in patients with a BAV.

First in Human Totally Endoscopic Perceval Valve Implantation.

Totally endoscopic cardiac operations for coronary procedures and atrial septal defect repair have demonstrated improved quality of life, but they have required longer cross-clamp times compared with open operations. Although transcatheter valve implantation remains appropriate for inoperable patients, the totally endoscopic approach could be an effective treatment for lower risk patients, including complete removal of the stenotic aortic valve, while minimizing surgical chest wall trauma, and providing excellent early quality of life. Totally endoscopic aortic valve replacement procedures were previously performed with the 3f Enable bioprosthesis.

Idiopathic Aortic Root to Right Atrial Fistula.

An aorta to right atrium fistula is rare. We report a case of idiopathic aortic root to right atrial fistula with right heart failure and review the literature. doi: 10.

Two Hundred Consecutive Implantations of the Sutureless 3f Enable Aortic Valve: What We Have Learned.

Background: In this article we present a consecutive single-center experience of implantation of the Medtronic 3f Enable aortic valve (Medtronic Inc, Minneapolis, MN).

Methods: Between March 2011 and October 2014, 200 consecutive patients (mean age, 76.4 ± 5.

Robotic total endoscopic sutureless aortic valve replacement: proof of concept for a future surgical setting.

Background: Sutureless valves have recently enabled closed chest aortic valve replacement. This paper evaluates the feasibility of a robotic telemanipulation during thoracoscopic sutureless aortic valve implantation in cadavers.

Methods: Cadavers were prepared with a five thoracosopic trocar setting, with a transthoracic clamp inserted in the first right intercostal space and the optics inserted in the second.

Mycoplasma hominis, a Rare but True Cause of Infective Endocarditis.

Mycoplasma spp. are rarely recognized agents of infective endocarditis. We report a case of Mycoplasma hominis prosthetic valve endocarditis diagnosed by 16S ribosomal DNA (rDNA) PCR and culture of valves in a 74-year-old man.

Sutureless 3f Enable valve implantation concomitant with mitral valve surgery.

Objective: Interest in aortic sutureless bioprostheses is growing. Here, we evaluate the feasibility of performing aortic sutureless valve replacement concomitant with mitral valve surgery using the 3f Enable prosthesis.

Methods: Of the 198 3f Enable® valve implantation procedures carried out in our unit between March 2011 and October 2014, 15 were performed concomitant with mitral valve surgery (8 bioprosthetic replacements and 7 annuloplasties).

Total endoscopic sutureless aortic valve replacement: rationale, development, perspectives.

Transcatheter valve implantation is progressively becoming the first line option for high risk patients in the management of severe aortic valve stenosis. Surgery is likely to remain the gold standard treatment option for intermediate risk patients since it ensures ablation of the underlying pathology and the calcified aortic valvular tissue, which potentially can act as a nidus of chronic embolization and provoke neurocognitive dysfunction in this subset of active patients. The surgical approach is continually evolving, with sutureless technology having the potential to facilitate ministernotomy and minithoracotomy approaches.

Feasibility of sutureless valve implantation in reoperation for degenerated 19 mm aortic valvular bioprostheses.

Background And Aim Of The Study: Transcatheter aortic valve implantation (TAVI) is a promising option to treat degenerated aortic valve bioprostheses, and may involve Valve-in-Valve (ViV) procedures. Unfortunately, the ViV technique may provide an inadequate relief of stenosis in small-diameter degenerated bioprostheses, especially in the 19 mm valve subgroup. The study aim was to determine the feasibility and reliability of reoperating 19 mm degenerated bioprostheses, using a minimally invasive sutureless valve implantation.

Sutureless prostheses and less invasive aortic valve replacement: just an issue of clamping time?

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.

Right anterior minithoracotomy aortic valve replacement with a sutureless bioprosthesis: Early outcomes and 1-year follow-up from 2 European centers.

Background: A sutureless aortic valve can be inserted through a right anterior minithoracotomy (RAMT) with consistent decreased cross-clamping time and ease of insertion. We report the experience of RAMT implantation of the 3f Enable (Medtronic, Inc, Minneapolis, Minn) self-expanding sutureless bioprosthesis, performed in 2 European cardiac surgery centers.

Method: From September 2012 to April 2014, a total of 71 patients with severe aortic stenosis were selected to receive an aortic valve replacement via RAMT using the sutureless valve.

Endovascular repair of mitroaortic intervalvular fibrosa aneurysm after bentall surgery.

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.

Giant left ventricular thrombus formation associated with heparin-induced thrombocytopenia.

A 33-year-old man underwent urgent coronary artery de-obstruction for acute thrombotic occlusion of the left descending coronary artery. After 10 days of antiplatelet and heparin therapy, ventriculographic and echocardiographic control revealed a giant thrombus in the left ventricle, an ejection fraction of 40%, and severe mitral regurgitation. Heparin-induced thrombocytopenia was diagnosed.

Video-assisted minithoracotomy approach: technical developments towards totally endoscopic sutureless aortic valve replacement.

Background And Aim Of The Study: Interest in sutureless aortic bioprostheses is growing because of the potential advantages that such devices can bring in facilitating minimally invasive approaches. Video assistance can potentially enhance details of decalcification and sutureless valve sizing. We review the feasibility of sutureless aortic valve replacement (AVR) via a minimally invasive video-assisted (MIVA) right anterior minithoracotomy.

Sutureless Medtronic 3f Enable aortic valve replacement in a heavily calcified aortic root.

The case is reported of a surgical aortic valvular stenosis with a severely calcified ascending aortic root in a 76-year-old woman. The morphology and size of the aortic annulus were unsuitable for transcatheter aortic valve implantation (TAVI); thus, surgery was scheduled. Aortic calcifications allowed a transverse aortotomy 4 cm superior to the sinotubular junction, with a remote endoaortic view of the valve.
