Filter by:The Mistral is an investigational device intended for percutaneous trans-catheter repair in high risk for surgery individuals suffering from functional Mitral Regurgitation. The device system is to be used only in accordance with the approved Investigational Plan on subjects who have signed an informed consent form. Device use is limited to the approved study investigators.
The purpose of this study is to use cardiac magnetic resonance (CMR) and echocardiography to define the anatomic and functional remodeling that results from MitraClip implantation. A total of sixty (60) patients undergoing MitraClip implantation will be enrolled across multiple sites. The severity of mitral regurgitation, cardiac morphology and function will be assessed in these patients by taking cardiac magnetic resonance imaging with an FDA approved contrast agent at BASELINE (within 30 days prior to MitraClip implantation), during the ACUTE REMODELING PHASE (pre-discharge following implantation), and during the CHRONIC REMODELING PHASE (6 months post-implantation).
A prospective, open-label, and multi-centered feasibility registry.
Percutaneous edge-to-edge repair of the mitral valve has been shown to be a safe and effective alternative treatment option for selected patients at high risk for cardiac surgery. Patients with recurrent mitral regurgitation after surgical mitral valve repair (sMVR) are per se at increased risk for another cardiac surgery. The purpose of this multicenter retrospective analysis of patients treated with a MitraClip® after sMVR, is to evaluate the effectiveness and durability of this minimally invasive treatment option in this subset of patients.
Serum-creatinine level (s-Cr) is an important factor for predicting perioperative patient's outcome regarding acute kidney injury. Although cardiopulmonary bypass (CPB), an essential procedure for cardiac surgery, dilutes patient's blood components, possible impact of applying acute normovolemic hemodilution (ANH) and CPB on s-Cr has not been well investigated. In patients undergoing cardiac surgery employing moderate hypothermic CPB (age 20-71 years, n=32), ANH will be randomly applied to 15 patients (Group-ANH) but not in 17 patients (Group-C) before initiating CPB. For ANH procedure consisting of 5 ml/kg of blood salvage and administering 5 ml/kg of balanced hydroxyethyl starch (HES) 130/0.4 for 15 min will be started at 30 min after anesthesia induction and before CPB application for surgery. In both groups, moderate hypothermic CPB will be initiated by using 1600-1800 ml of bloodless priming solution. The changes of hematocrit (Hct), Na+, K+, HCO3-, Ca2+, osmolarity, s-Cr will be determined before ANH (T1), after the first ANH of 2.5 ml/kg (T2), and after the second ANH of 2.5 ml/kg (T3), 30 sec and 60 sec after the initiation of CPB (T4, T5), immediately and 1 hour after the weaning from CPB (T6, T7) and at the end of surgery (T8). S-Cr will be determined by using a point-of-care test device (StatSensor™ Creatinine, Nova Biomedical, USA).
The main objective is to assess the effectiveness and safety of the NeoChord DS1000 repair technique as compared with conventional open-heart on-pump mitral valve surgery in patients with severe primary mitral regurgitation.
The purpose of this study is to prospectively evaluate major and minor neurologic events in patients undergoing right mini-thoracotomy mitral valve surgery and to compare different aortic clamping techniques; specifically, the endoaortic balloon with retrograde perfusion (Endoreturn) and the transthoracic clamp with retrograde perfusion. Major neurologic events will be evaluate through standard neurologic evaluation; minor neurologic events will be evaluate through magnetic resonance (MR) assessment. The first aim of the study is to determine the number and impact of microembolic events during right mini-thoracotomy mitral valve surgery on clinical neurological status and on MR evaluation. The investigators also aim to determine if different techniques of aortic clamping may impact on early outcome. Study hypothesis: despite recent concerns arising about endoaortic balloon with retrograde perfusion, the investigators expect to show equivalence in term of safety and effectiveness of this technique compared with the transthoracic clamp in a selected population.
This is a multi-center, non-randomized, prospective Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in patients with symptomatic heart failure and concomitant functional mitral regurgitation that have stable symptoms on guideline-directed medical therapy
The objective of this trial is to assess the safety and effectiveness of the study device in subjects with degenerative mitral valve disease receiving a mitral valve repair without cardiopulmonary bypass (treatment group) when compared to subjects receiving mitral valve repair using standard surgical techniques with cardiopulmonary bypass (control group).
The purpose of this study is to evaluate the safety and performance of the Harpoon Medical TSD-5. The Harpoon device will provide many significant advantages over current surgical interventions including: 1) a small minimally invasive incision, 2) no sternotomy, 3) no cardiopulmonary bypass, 4) no aortic manipulation, 5) a direct path to the valve plane, 6) performed on a beating heart, 7) real-time TEE-guided chordal length adjustment and 8) less complicated procedure that is teachable and adoptable.
