Filter by:Observational study in adult humans undergoing surgical or cardiological intervention for mitral valve insufficiency. Investigators aim to evaluate hemodynamic changes on an arterial pressure waveform level in patients before and after mitral valve intervention using Nexfin (BMEYE, Amsterdam, the Netherlands) continuous non-invasive hemodynamic monitoring, using finger cuff based technology to register beat-to-beat data
The absence of residual mitral regurgitation (MR) after mitral valve repair is of paramount importance for the long term durability of the valve repair. Thus, ideally, after weaning from cardio-pulmonary by-pass (CPB) the trans-esophageal echocardiogram (TEE) should show no (or only trivial) residual MR, good coaptation length and no iatrogenic mitral valve stenosis. However, mild or more residual MR can be present in up to 4% of the patients after the initial mitral valve repair and a second CPB run may be necessary to improve the repair results. Mechanism of residual MR can be dynamic, related to systolic anterior motion (SAM) or to severe left ventricular dysfunction, and anatomical, related to residual prolapse, cleft, and suture or ring dehiscence. In several cases medical therapy can be effective in the management of the intra-operatively detected SAM, and residual cleft or suture dehiscence can be easily corrected during a second CPB run. However, in other cases SAM is not responsive to medical therapy or the residual MR jet would require complex and time-consuming techniques to be addressed, or even worse scenario, a mitral valve replacement could be necessary. In such cases the edge-to-edge (EE) technique can be used as a bail-out procedure. The anatomical characteristics of the mitral valve after an initial sub-optimal repair are certainly not ideal for the edge-to-edge technique, due to a possible significant reduction in the valve area, especially in case of posterior leaflet resection or small ring implanted. Nevertheless, in the short term the edge-to-edge technique used to rescue patients with sub-optimal initial repair resulted effective. However, the very long-term results of the edge-to-edge technique used as bail-out are not known. Thus, the aim of this study is to evaluate the clinical and echocardiographic results of the edge-to-edge technique used to rescue patients with initial sub-optimal mitral repair.
This is a prospective Quality Improvement (QI) study using the Model for Improvement framework. The objective of this study is to implement a structured, comprehensive, innovative, and sustainable approach to the management of patients with advanced mitral valve (MV) disease and heart failure (HF) in Southeastern Ontario and to improve healthcare delivery, patient care, and patient outcomes in the context of structural surgical and percutaneous MV interventions. This will be achieved through the strategic implementation, promotion, and evaluation of: i.The first local Southeastern Ontario Structural Mitral Valve Clinic using an Interdisciplinary heart team (IHT) at the Kingston Health Sciences Centre (KHSC) and its integration with the KHSC's existing Heart Failure Clinic; ii.The first provincial Structural Mitral Valve Clinic electronic referral service on the Ontario electronic services platform; and iii.The promotion of the above through targeted KT (Knowledge Transfer) outreach activities. Patients for this study will be recruited through medical referral within the south eastern Ontario, Canada region.
This is a retrospective and prospective, multi-center, post-market observational registry study. The primary objective of this post market registry is to continue to evaluate the long term safety and performance of the Carillon® Mitral Contour System® (CMCS) in a commercial (post market) setting.
To observe and evaluate the safety and efficacy of the GeminiOne Transcatheter Valve Edge-to-Edge Repair System in Patients With Moderate-severe or Severe Degenerative Mitral Regurgitation through a prospective, multicenter clinical trial using objective performance criteria.
To observe and evaluate the safety and efficacy of the HighLife Transcatheter Mitral Valve Replacement System in patients with moderate-severe or severe mitral valve regurgitation through a prospective, multicenter clinical trial using objective performance criteria.
Tricuspid regurgitation is common in patients with severe left heart diseases, such as degenerative mitral regurgitation. However, the evidence base is insufficient to inform a decision about whether to perform concomitant tricuspid-valve repair during left heart surgery in patients who have mild tricuspid regurgitation. To inform decision making, we will conduct a multicenter, randomized trial to assess the benefits and risks of tricuspid-valve repair at the time of left heart diseases in patients with mild tricuspid regurgitation who were undergoing surgery for left heart surgery.
Evaluate the safety and efficacy of Medtronic Intrepid™ TMVR TF System in patients with moderate-to-severe or severe symptomatic mitral regurgitation, or moderate symptomatic mitral regurgitation combined with mitral stenosis in the presence of MAC who, by agreement of the local site multidisciplinary heart team experienced in mitral valve therapies, are unsuitable for treatment with approved transcatheter repair or surgical mitral valve intervention.
The current study is designed to compare the perioperative analgesic efficacy of Erector spinae plane block (ESPB) and Pecto-intercostal-fascial plane block (PIFB) in adults undergoing cardiac surgery via median sternotomy. The primary outcome measure will be the analgesic effectiveness of both blocks in median sternotomy pain, while the secondary outcome measures will be time to extubation, and length of intensive care unit stay.
