The objective is to demonstrate safety and early clinical results of surgical transapical closure of paravalvular leaks (PVLs) following mitral valve replacement in significant regurgitation. Between March 2014 and February 2015, 12 patients (mean age 52.1 ± 6.0 years, 66.6% male) with severe symptomatic mitral PVLs (n = 13) underwent surgical transapical closure procedure through left mini-thoracotomy. All patients were in NYHA functional class III-IV and median logistic EuroSCORE was 24.2 ± 6...

Valve-in-valve and valve-in-ring transcatheter mitral valve replacement can be used in for the treatment of inoperable patients with failing mitral surgical bioprosthesis or valve repairs. Preprocedural multi-image evaluation by a heart team must include transthoracic echocardiogram, transesophageal echocardiogram, and cardiac computed tomography angiography (CTA). CTA is used to determine access site (transapical, transseptal, or transatrial), transcatheter valve size, and landing zone. Though complications can occur (ie, valve embolization, bleeding, or vascular complications), this less invasive procedure has a reported success rate of 70% to 100% and is now increasingly used...

We describe a successful transcatheter, transapical mitral valve implant within a failed mitral bioprosthesis (valve-in-valve) in a symptomatic 86-year-old patient with prohibitive surgical risks, using the new Sapien 3 balloon-expandable valve. Post-deployment echocardiographic profile of the valve-in-valve was satisfactory and the patient was discharged from hospital uneventfully. This is the first reported case of the Sapien 3 valve used in the mitral valve-in-valve setting.

BACKGROUND AND AIM: Artificial chordal implantation in order to repair flail or prolapse mitral valve leaflet requires open heart surgery and cardiopulmonary bypass. Transapical off-pump implantation of neochordae is a new surgical technique proposed to treat degenerative mitral valve regurgitation. The procedure is performed using the NeoChord DS1000 system (NeoChord, Inc., Eden Praire, MN), which facilitates both implantation and tension adjustment of the neochordae under transesophageal echocardiographic 2D and 3D guidance...

OBJECTIVES: Various minimally invasive surgical approaches have been used in mitral valve (MV) surgery. The transapical off-pump mitral valve intervention with NeoChord implantation (TOP-MINI) is a minimally invasive, alternative procedure for the treatment of degenerative mitral regurgitation. There are several special considerations for the anesthesiologist during the TOP-MINI procedure. The main purpose of this study was to present the anesthetic management of the TOP-MINI procedure...

Elderly patients with severe hematological malignancies may require cardiac surgery. The combined impact of cardiopulmonary bypass (CPB) and surgical trauma is a potent inflammatory activator and is increased by intraoperative and postoperative complications. To avoid the adverse effects of CPB, minimally invasive off-pump techniques may be used in these patients. The transapical off-pump mitral valve intervention with NeoChord implantation (TOP-MINI) is a minimally invasive technique for mitral valve repair, which makes it possible to avoid the risks of CPB in selected patients, such as elderly, cancer or immunosuppressive patients...

A novel transapical coaptation plate (TCP) device was developed and anchored by sutures in the mitral valve to treat functional mitral regurgitation. The objective of this study was to test efficacy of the TCP in an in vitro model. Eight fresh porcine mitral valves were mounted in a left heart simulator to simulate functional mitral regurgitation by means of annular dilatation and asymmetrical or symmetrical papillary muscle (PM) displacement. Six polyurethane TCPs in thickness of 6.4(#1), 4.8(#2), 3.2(#3) mm and hardness of durometer 30 A (H) and 30 OO(S),were fabricated and labeled as H1, H2, H3 and S1, S2, S3, respectively...

OBJECTIVE: A small number of transcatheter mitral valve implants (TMVIs) have been reported using devices designed to treat secondary mitral regurgitation (MR). However, MR has many etiologies, and patients have a broad spectrum of annular size, geometry, and lesions. There are a number of technical challenges for TMVI including left ventricular outflow tract obstruction and paravalvular MR. Thirty days' outcome of first-in-man implants with a novel TMVI device is reported. METHODS: The Tendyne TMVI system consists of a porcine pericardial valve in a tethered nitinol frame...

We present a complex case of a transapical redo mitral valve-in-valve replacement. Repeat mitral valve replacement was indicated for severe symptomatic bioprosthetic stenosis. In addition to the patient's numerous comorbidities that included diabetes, hepatic cirrhosis, ischemic cardiomyopathy, and atrial flutter, he had undergone a previous open mitral valve replacement that was complicated by sternal dehiscence requiring extensive chest wall reconstruction. Transapical approach was performed through left minithoracotomy incision with balloon-expandable valve...

A 71-year-old man presented with New York Heart Association (NYHA) class IV heart failure. He had undergone transapical mitral valve replacement for mixed mitral stenosis and mitral regurgitation. At the 1 month follow-up, the patient reported symptom resolution. An echocardiogram revealed a low gradient and no regurgitation. Our case shows that with careful multidisciplinary evaluation, preoperative planning, and patient selection, percutaneous mitral intervention can become an alternative therapy for high-risk patients who cannot undergo conventional surgical therapy...

BACKGROUND: Degenerative mitral valve (MV) disease is a common cause of severe mitral regurgitation (MR) and accounts for the majority of MV operations. Conventional MV surgery requires cardiopulmonary bypass, aortic cross-clamping, cardioplegia, and a thoracotomy or sternotomy and, therefore, is associated with significant disability, risks, and unpredictable rates of MV repair. Transesophageal echocardiography-guided beating-heart MV repair with expanded polytetrafluoroethylene cordal insertion has the potential to significantly reduce surgical morbidity...

Transapical valve-in-valve mitral valve implantation (TA-MVI) has been described as an alternative treatment option in patients with degenerated bioprostheses in the mitral position. We report the first case of prosthesis dislocation and migration into the left atrium after TA-MVI. A new prosthesis was implanted using the same approach. The dislocated prosthesis was successfully removed through the left atrial appendage through an extended anterolateral thoracotomy without the use of cardiopulmonary bypass.

A 67-year-old patient with rheumatic heart valve disease had undergone two cardiac surgeries at the age of 30 years, then re-do with mitral valve replacement at 50 years. She presented with congestive heart failure and hemolytic anemia. Doppler echocardiography showed moderate-severe mitral regurgitation due to paravalvular mitral valve leak (PVML) and severe pulmonary hypertension. Transesophageal echocardiography demonstrated severe PVML secondary to a large 20 mm-long PVML defect. Due to comorbidities, the heart team deemed a third reoperation at very high surgical risk; therefore, the patient was considered most suitable for a transcatheter approach to PVML closure...

AIMS: Transcatheter mitral valve implantation (TMVI) is a novel approach that may enable a less invasive effective reduction of mitral regurgitation (MR). A limitation of the MitraClip is that definitive implantation of a clip precludes future therapy with TMVI. The purpose of this paper is to describe contemporary treatment considerations in patients with mitral valve regurgitation. METHODS AND RESULTS: In this report we describe an attempted MitraClip implantation which resulted in no reduction of MR severity...
