Contemporary review of the evolution of various treatment modalities for mitral regurgitation.

Introduction: Mitral regurgitation is one of the most common forms of valvular heart diseases for which there have been several innovative treatment strategies that have developed over the last several decades. We describe the various treatment modalities that have been used for the last several decades. All articles in PubMed, Cochrane, and Embase were screened from inception to August 2024 for the following - 'Mitral valve regurgitation' 'Mitral valve repair' 'Mitral valve replacement' 'Robotic mitral surgery' 'Transcatheter mitral valve repair.

Midterm outcomes of aortic valve replacement using a rapid-deployment valve for aortic stenosis: TRANSFORM trial.

Background: The use of rapid-deployment valves (RDVs) has been shown to reduce the operative time for surgical aortic valve replacement (AVR). Long-term core laboratory-adjudicated data are scarce, however. Here we report final 7-year data on RDV use.

Historical evolution of robot-assisted cardiac surgery: a 25-year journey.

Many patients and surgeons today favor the least invasive access to an operative site. The adoption of robot-assisted cardiac surgery has been slow, but now has come to fruition. The development of modern surgical robots took surgeons close collaboration with mechanical, electrical, and optical engineers.

Impact of Anchor Location on Mitral Neochordae Forces: An In Vitro Study.

Purpose: This study examined changes in force distribution between the neochordae corresponding to different ventricular anchor locations.

Description: Seven porcine mitral valves were mounted in a left heart simulator. Neochordae (expanded polytetrafluoroethylene) originated from either a simulated left ventricular apex, papillary muscle base, or papillary muscle tip location.

Comparative differences of mitral valve-in-valve implantation: A new mitral bioprosthesis versus current mosaic and epic valves.

Objective: Evaluate transcatheter mitral valve replacement (TMVR) valve-in-valve (VIV) outcomes in three different mitral bioprostheses (of comparable measured internal diameters) under stable hemodynamic and surgical conditions by bench, echocardiographic, computerized tomography (CT), and autopsy comparisons pre- and post-valve implantation in a porcine model under matched controlled conditions.

Background: Impact of surgical bioprosthesis design on TMVR VIV procedures is unknown.

Methods: Fifteen similar-sized Yorkshire pigs underwent pre-procedural CT screening.

Comparison of a new bioprosthetic mitral valve to other commercially available devices under controlled conditions in a porcine model.

Background/aim: To evaluate three mitral bioprostheses (of comparable measured internal diameters) under controlled, stable, hemodynamic and surgical conditions by bench, echocardiographic, computerized tomography and autopsy comparisons pre- and postvalve implantation.

Methods: Fifteen similar-sized Yorkshire pigs underwent preprocedural computerized tomography anatomic screening. Of these, 12 had consistent anatomic features and underwent implantation of a mitral bioprosthesis via thoracotomy on cardiopulmonary bypass (CPB).

Initial in-human experience with the conveyor cardiovascular system for the delivery of large profile transcatheter valve devices.

Objectives: To determine the safety and efficacy of the conveyor cardiovascular system (CCS) to facilitate the delivery of large profile transcatheter valve devices.

Background: Transcatheter valve devices rely on force provided by the operator to be delivered to their intended position. This delivery may be challenging in a variety of anatomic scenarios.

Reoperative, transapical off-pump neochordae implantation for recurrent degenerative mitral regurgitation resulting from a newly ruptured native chord.

Transapical mitral valve repair with NeoChord implantation is effective and safe to replace ruptured chordae due to degenerative disease. Redo transapical neochordae implantation has never been reported in the literature. We present a case report of a 53-year-old man who underwent a reoperative neochord implantation for recurrent severe mitral regurgitation, resulting from degenerative disease progression with a new native chordal rupture.

The EACTS simulation-based training course for endoscopic mitral valve repair: an air-pilot training concept in action.

Objectives: We have developed a high-fidelity minimally invasive mitral valve surgery (MIMVS) simulator that provides a platform to train skills in an objective and reproducible manner, which has been incorporated in the European Association for Cardiothoracic Surgery (EACTS) endoscopic mitral valve repair course. The aim of the study is to provide data on the application of simulation-based training in MIMVS using an air-pilot training concept.

Methods: The 2-day EACTS endoscopic mitral training course design was based on backwards chaining, pre- and post-assessment, performance feedback, hands-on training on MIMVS, theoretical content and follow-up.

A propensity matched analysis of robotic, minimally invasive, and conventional mitral valve surgery.

Objectives: Institutional studies suggest robotic mitral surgery may be associated with superior outcomes. The objective of this study was to compare the outcomes of robotic, minimally invasive (mini), and conventional mitral surgery.

Methods: A total of 2300 patients undergoing non-emergent isolated mitral valve operations from 2011 to 2016 were extracted from a regional Society of Thoracic Surgeons database.

Step-by-Step Aortic Valve Replacement With a New Rapid Deployment Valve.

Purpose: Rapid deployment/sutureless aortic valve replacement is aimed at minimizing the invasiveness of surgical aortic valve replacement. We describe the implantation techniques of a new rapid deployment aortic valve, focusing on its unique and challenging features.

Description: The EDWARDS INTUITY Elite aortic valve (Edwards Lifesciences, Irvine, CA) represents a hybrid between the surgical PERIMOUNT Magna Ease (Edwards Lifesciences) pericardial valve, but with advanced features of the percutaneous SAPIEN valve system (Edwards Lifesciences).

Use of a New Expanded Polytetrafluoroethylene Multichordal Mitral Apparatus (MitraPatch) to Repair Complex Mitral Valve Lesions.

Objective: We report a new expanded polytetrafluoroethylene multichordal mitral apparatus (MitraPatch) to simplify mitral repairs involving multiple cusps and sought to describe the surgical technique and demonstrate the efficacy of the device.

Methods: MitraPatch was laser cut from a single sheet of expanded polytetrafluoroethylene and mounted on a custom-designed handle. Surgical technique to deploy the apparatus on the native mitral valve was developed in ex vivo porcine hearts.

The dynamic cardiac biosimulator: A method for training physicians in beating-heart mitral valve repair procedures.

Objective: Previously, cardiac surgeons and cardiologists learned to operate new clinical devices for the first time in the operating room or catheterization laboratory. We describe a biosimulator that recapitulates normal heart valve physiology with associated real-time hemodynamic performance.

Methods: To highlight the advantages of this simulation platform, transventricular extruded polytetrafluoroethylene artificial chordae were attached to repair flail or prolapsing mitral valve leaflets.
