OBJECTIVES: Reoperative procedure for the treatment of a failed mitral bioprosthesis is associated with considerable risk. In some cases, mortality is high and might contraindicate the benefit of the procedure. The minimally invasive valve-in-valve (ViV) transcatheter mitral valve implant offers an alternative less-invasive approach, reducing morbidity and mortality. The objective of this paper was to evaluate the mitral ViV approach using the Braile Inovare prosthesis. METHODS: The transcatheter balloon-expandable Braile Inovare prosthesis was used in 12 cases...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of severe aortic stenosis in intermediate, high-risk, and inoperable patients. TAVR has multiple access routes, including transfemoral (TF), transapical (TA), direct aortic (DA), axillary, transcarotid, and transcaval. The most commonly applied algorithm is a TF-first approach, where only when patients are unsuitable for TF are alternatives such as TA considered. An infrequent - but dreaded - risk is left ventricular (LV) apical bleeding from tearing or rupture with the TA approach...

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...
