Transcatheter mitral valve replacement (TMVR) is a novel approach for treatment of severe mitral regurgitation. A number of TMVR devices are currently undergoing feasibility trials using both transseptal and transapical routes for device delivery. Overall experience worldwide is limited to fewer than 200 cases. At present, the 30-day mortality exceeds 30% and is attributable to both patient- and device-related factors. TMVR has been successfully used to treat patients with degenerative mitral stenosis (DMS) as well as failed mitral bioprosthesis and mitral repair using transcatheter mitral valve-in-valve (TMViV)/valve-in-ring (ViR) repair...

BACKGROUND: Transapical, beating heart, off-pump implantation of neochordae for repair of mitral valve (MV) prolapse is of increasing interest. The aim of this study was to evaluate long term results for MV repair using the NeoChord system. METHODS: Six patients underwent treatment for severe primary mitral regurgitation (MR) using the NeoChord DS1000 system as part of the initial device safety and feasibility Transapical Artificial Chordae Tendinae (TACT) trial at our institution...

OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model...

Transcatheter mitral valve replacement with the Tiara 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 the case of mono-disk mechanical prostheses 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 27-mm mono-disk mechanical aortic valve implanted in 1978, a EuroSCORE II of 18%, and a Society of Thoracic Surgeon score (mortality) of 16% who successfully underwent a transapical Tiara 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...

OBJECTIVES: Transapical off-pump NeoChord repair is a novel minimally invasive surgical procedure to treat degenerative mitral valve regurgitation. The aim was to evaluate 1-year clinical results of the NeoChord procedure in a consecutive cohort of patients. METHODS: Between February 2013 and July 2016, 213 patients were enrolled in the NeoChord Independent International Registry. All patients presented severe mitral regurgitation due to flail/prolapse of 1 or both leaflets, and they all completed postoperative echocardiographic assessment up to 1 year...

OBJECTIVES: Transapical off-pump mitral valve intervention with neochordae implantation is a novel, minimally invasive procedure for treatment of degenerative mitral valve regurgitation. The aim of this study was to apply control charts (CUSUM curves) to monitor the performance of NeoChord repair during the initial phase of its adoption. METHODS: The first 112 consecutive patients who underwent NeoChord repair at our institution between November 2013 and March 2016 were included in the analysis...

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...

REVIEW
Minoru Tabata
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.

BACKGROUND: Transapical implantation of artificial chordae using the NeoChord system (NeoChord Inc, Minneapolis, MN) is an emerging beating-heart technique for correction of mitral regurgitation (MR) through a minimally invasive left minithoracotomy. The purpose of the study was to describe the anesthetic management and procedural success of patients undergoing this procedure. METHODS: All patients (n = 76) who underwent mitral valve repair with the NeoChord system in our institution from December 2011 to December 2016 were included in this observational prospective study...

We present the case of a high-risk patient with symptomatic severe mitral regurgitation following a surgical annuloplasty ring. An inverted aortic Edwards Sapien 3 bioprosthesis (Edwards Lifesciences, Irvine, CA) was successfully implanted through a transapical approach inside the previously implanted annuloplasty ring.

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...
