Filter by:The goal of this project is to study whether local anesthetic via the erector spinae plane (ESP) block may be beneficial in minimally invasive mitral valve surgery (MIMVS).
Mitral valve (MV) repair has turned into a preferable option for surgeons over the MV replacement. Since the 1960s, Surgeons use this technique for more efficiency and durability. On the other hand, the proper determination of length and placement of artificial neochordae is still a challenge beyond this technique. These challenges are still a vital area for research and debate between surgeons and researchers. In our novel technique,Investigators are not depending either on the preoperative investigations or intraoperative reference chordae in the adjustment of the optimal length of the neochordae, however, Researchers depend on the personal adjustment of the chordal length to the prolapsed scallop.
The study aims to analyze the role of left ventricular and left atrial functional parameters by speckle tracking echocardiography in predicting outcome after mitral valve replacement and targeting for early intervention compared to guideline parameters.
Mitral valve disease is a common pathologic problem occurring in approximately 2% of the general population but climbing to 10% in those over the age of 75 in Canada[1]. This project has three primary goals all of which will positively affect cardiac patient care. 1) Create patient specific MV models for complex repairs that will allow surgeons the opportunity to practice the repair. 2) Potentially predict the outcomes following minimally invasive repair techniques such as transcatheter treatments (e.g., MitraClip). 3) Provide a model to train individuals on mitral valve repair techniques.
During general anesthesia a reduction of Functional Residual Capacity (FRC) was observed. The reduction of FRC could imply that respiratory system closing capacity (CC) exceeds the FRC and leads to a phenomenon called expiratory flow limitation (EFL). Positive End-Expiratory Pressure (PEEP) test is a validated method to evaluate the presence of EFL during anesthesia. Aim of the study will be to asses if mechanical ventilation during CardioPulmonary Bypass (CPB) in cardiac surgery could reduce the incidence of EFL in the post-CPB period. Primary end-point will be the incidence of EFL, assessed by a PEEP test, performed at different time-points in operating room. Co-primary end-point will be shunt fraction, determined before and after surgery. This will be a single center single-blind parallel group randomized controlled trial. Patients will be randomly assigned to four parallel arms with an allocation ratio 1:1:1:1, to receive one of four mechanical ventilation strategies during CPB. 1. Ventilation with a Positive End-Expiratory Pressure (PEEP) of 5 cmH2O before and after CPB; Continuous Positive Airway Pressure (CPAP) during CPB; 2. Ventilation without PEEP before and after CPB; CPAP during CPB; 3. Ventilation with a PEEP of 5 cmH2O before and after CPB; No use of mechanical ventilation during CPB 4. Ventilation without PEEP before and after CPB; No use of mechanical ventilation during CPB
The primary objective in this randomized trial is to evaluate the safety and efficacy of a MitraClip treatment in symptomatic patients with severe mitral regurgitation in comparison to the previous default medical treatment - in a study population who is not amenable for the conventional surgical approach as current gold standard.
The purpose of this study is to show that CRT(Cardiac Resynchronization Therapy) pacing in patients with severe functional MR (Mitral Regurgitation) who are not currently indicated for CRT will demonstrate chronic benefit of MR reduction( via echo measured MR/LA area and ERO per American Society of ECHO guidelines) and to show that CRT pacing is safe in these patients.
