Transcatheter mitral valve replacement with the TiaraTM valve can be performed in inoperable patients with severe functional regurgitation. Risk of left ventricular outflow tract obstruction can be prevented using preoperative 3D-imaging and 3D-printed models. However, in case of mono-disk mechanical prosthesis previously implanted in aortic position (Bjork-Shiley) there is an additional risk of mechanical interference leading to reduced leaflet motion and aortic valve dysfunction. Hereafter, we describe the case of a patient with a 27mm mono-disk mechanical aortic valve implanted in 1978, Euroscore-II of 18% and STS-score (mortality) of 16% who successfully underwent a transapical TiaraTM valve implantation...

Transapical transcatheter aortic valve implantation is a well-established alternative in patients at a high risk for conventional aortic valve replacement. We performed transapical transcatheter aortic valve implantation on an 83-year-old woman with symptomatic severe aortic stenosis. Intraoperative transoesophageal echocardiography (TOE) after transcatheter aortic valve implantation showed mild mitral regurgitation without intracardiac structural injury. In the intensive care unit, the patient gradually had haemodynamic instability; TOE revealed severe mitral regurgitation with A2 and A3 prolapse due to rupture of the posterior papillary muscle...

BACKGROUND: The transapical echo-guided NeoChord repair is a procedure to correct mitral regurgitation (MR) without the need for concomitant annuloplasty for degenerative mitral valve (MV) disease. Lacking strict criteria to define normal annular dimensions for patients undergoing MV repair, we consequently missed having precise selection criteria to identify patients who can benefit from a ringless procedure with respect to who would need a combined annular and leaflet repair. The aim of this study is to identify whether a new preoperative echocardiographic index may predict postoperative outcomes after NeoChord repair...

OBJECTIVES: Our aim is to investigate the acute intraoperative effects of the NeoChord repair procedure on mitral valve (MV) annular geometry and LV function and the impact of these changes on MR at 1-year follow-up. BACKGROUND: Recently transapical off-pump mitral valve repair with NeoChord implantation has been demonstrated to be safe and effective in patients with degenerative mitral regurgitation (DMR). METHODS: We retrospectively analyzed baseline and early postoperative 3-dimensional transesophageal echocardiography of 66 patients who underwent NeoChord repair for isolated posterior leaflet MV disease using semiautomatic off-line analysis software...

BACKGROUND: Transapical transcatheter mitral valve-in-valve implantation (TA-MVIVI) for bioprosthetic valve failure is an emerging alternative to re-operation in high risk patients. We report our outcomes in a patient population with a high proportion of cardiogenic shock. METHODS: Retrospective review was performed of all patients undergoing TA-MVIVI with an Edwards SAPIEN (Edwards Life sciences, Irvine, CA) prosthesis at our center between the years of 2013-2017...

The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access. The apex has been chosen as a primary access site for many devices of transcatheter mitral valve repair/replacement and mitral valve-in-valve procedures. Additionally, the transapical approach has been used for other transcatheter cardiovascular interventions such as paravalvular leak repair after mitral or aortic valve replacement, pseudoaneurysm repair of the left ventricular outflow tract, and thoracic endovascular aortic repair...

Mitral paravalvular leak (PVL) remains a well-known complication after mitral valve replacement. Since the first report over 25 years ago, several catheter-based PVL closure techniques have been described. Most of these comprise of either an antegrade transseptal approach, or a retrograde transaortic or transapical approach. We herein report a novel percutaneous mitral PVL closure technique that was safely and successfully performed after failed attempt using a conventional antegrade approach.

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

BACKGROUND: Transcatheter mitral valve replacement (TMVR) is a potential therapy for patients with symptomatic, severe mitral regurgitation (MR). The feasibility of this therapy remains to be defined. OBJECTIVES: The authors report their early experience with TMVR using a new valve system. METHODS: The valve is a self-expanding, nitinol valve with bovine pericardial leaflets that is placed using a transapical delivery system. Patients with symptomatic MR who were deemed high or extreme risk by the local heart teams were enrolled in a global pilot study at 14 sites (United States, Australia, and Europe)...

Transapical off-pump echo-guided mitral valve repair with implantation of artificial ePTFE chordae with the Harpoon device has been proposed to treat patients presenting with severe mitral regurgitation due to posterior leaflet prolapse. The device is inserted in the left ventricle and steered to the surface of the diseased portion of the leaflet. The Harpoon device is actuated, and the leaflet is perforated by a needle that consequently releases an ePTFE chord that is fixed on the atrial surface by a double-helix coiled knot...

Off-pump direct coronary artery bypass grafting through a left anterior small thoracotomy is widely utilized for minimally invasive myocardial revascularization. More recently, a novel technique for transapical off-pump mitral valve repair with the NeoChord device is demonstrating its efficacy. This report describes a case of an 84-year-old male patient with coronary artery disease involving the left anterior descending coronary artery and acute severe mitral regurgitation secondary to posterior leaflet flail who underwent both off-pump coronary artery bypass and mitral valve repair with the transapical implantation of artificial chordae using the NeoChord DS 1000 system through the same anterolateral small thoracotomy...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...

In patients with mechanical aortic and mitral valve prosthesis, left ventricular (LV) endocardial ablation via retrograde transaortic or antegrade transmitral approach carry high risk of catheter entrapment and death. In such cases, ablation can be performed via ventricular transseptal or transapical approach. Transapical approach, with the ease of catheter maneuverability and better endocardial contact, may be performed surgically or percutaneously. In this case report, we describe a patient with both aortic and mitral mechanical prosthesis who underwent ventricular tachycardia (VT) ablation via percutaneous transapical endocardial approach with the use of closure device...
