Clinical Presentation and Outcomes After Surgery for Mitral Regurgitation: Real-World Insights From the MITRACURE International Registry.

Background: Comprehensive knowledge of the clinical presentation, contemporary management, and outcomes on "allcomer" patients referred for mitral valve surgery (MVS) are critical to evaluate current practice and adherence to guidelines, understand selection biases, and inform key stakeholders on quality improvement.

Methods: MITRACURE is a large international retrospective registry of consecutive adult patients who underwent isolated or combined MVS for mitral regurgitation (MR) in France or Canada in 2019 with in-depth clinical and echocardiographic characterization. Patients operated on for isolated mitral stenosis or who had a prior mitral valve intervention were excluded.

Optimizing Recovery in Cardiac Surgery: A Narrative Review of Enhanced Recovery After Surgery Protocols and Clinical Outcomes.

Enhanced Recovery After Surgery (ERAS) is an evidence-based, holistic perioperative recovery protocol intended to improve patient outcomes and decrease postoperative complication rates. While ERAS protocols were first introduced in 1997, specific guidelines for cardiac surgery were not established until 2019. Although the core principles of ERAS remain constant across surgical disciplines, ERAS guidelines for cardiac surgery have remained relatively understudied, likely due to the unique complexities posed by cardiac procedures.

Cost Analysis for Minimally Invasive Mitral Valve Surgery: A Single-Centre Canadian Study.

Background: Stakeholders within a publicly funded healthcare system have a duty to consider costs and economics, to utilize finite resources in the most effective manner. We aimed to quantify the postoperative costs associated with mitral valve repair (MVR) at the Foothills Medical Centre in Calgary, Canada.

Methods: A retrospective review of patients who underwent MVR from January 2020 to November 2023 was performed.

Minimally Invasive Tricuspid Valve Surgery: An Alternative Surgical Approach in the Era of Transcatheter Interventions.

There has been significant growth in minimally invasive valve surgery over the past 2 decades, with novel approaches including video-assisted minithoracotomy, totally endoscopic, and robotic assisted. Outcomes of these techniques suggest that they can improve patient-reported outcomes, enhance mobility, reduce blood loss, and facilitate earlier discharge and return to work. Minimally invasive tricuspid valve surgery now provides surgeons and patients with an alternative option for treating tricuspid valve disease.

Rapid-recovery protocol for minimally invasive mitral valve repair.

Background: Minimally invasive mitral valve repair (MIMVR), often performed within specialized care pathways, has been shown to reduce hospital length of stay and improve patient recovery. The relative value of rapid-recovery protocols as a component of care pathways, including enhanced recovery programs (ERPs), has not been well described. This study compared clinical outcomes following implementation of a new, comprehensive rapid-recovery protocol within a previously established, mature ERP for patients undergoing MIMVR.

Midterm Outcomes of Right Anterior Mini Thoracotomy Aortic Valve Replacement.

Background: Contemporary surgical approaches for aortic valve replacement (AVR) include full median sternotomy, hemi-sternotomy, and a right anterior mini thoracotomy (RAMT) approach. We report the midterm outcomes of RAMT for isolated AVR.

Methods: A retrospective study was conducted, reporting the midterm outcomes of patients who underwent isolated RAMT AVR.

Direct Implantation of Transcatheter Valve in Mitral Annular Calcification: A Multicenter Study.

Background: Mitral valve replacement in the setting of severe annular calcification (MAC) is associated with high morbidity and mortality. Direct surgical implantation of a transcatheter heart valve (THV) through a transatrial approach is a strategy to mitigate surgical risk. This study reports the perioperative and 1-year outcomes of mitral valve replacement using a THV in patients with severe circumferential MAC at 3 Canadian centers.

Right Anterior Minithoracotomy Approach for Aortic Valve Replacement.

By sparing the sternum, the right anterior minithoracotomy (RAMT) approach may facilitate a quicker functional recovery when compared with conventional aortic valve replacement (AVR). In the following review, outcomes after RAMT AVR are compared with full sternotomy AVR. The RAMT approach is described, including suggestions for patient selection.

Right anterior mini thoracotomy for redo cardiac surgery: case series from North America and Europe.

Background: Right anterior mini thoracotomy (RAMT) for aortic valve replacement (AVR) is a minimally invasive procedure that avoids sternotomy. Herein, we report the outcomes of patients who underwent redo-cardiac via a RAMT approach for AVR.

Methods: This case series reports the clinical outcomes of 14 consecutive redo operations, done in Calgary (Canada) and Gdansk (Poland) between 2020 and 2023.

Treatment of RAF1-Related Obstructive Hypertrophic Cardiomyopathy by MEK Inhibition Using Trametinib.

RASopathies cause nonsarcomeric hypertrophic cardiomyopathy via dysregulated signaling through RAS and upregulated mitogen-activated protein kinase activity. We provide the first report of the successful treatment of an adult with RAF1-associated hypertrophic cardiomyopathy using trametinib, a MEK inhibitor.

Closing the care gap: combining enhanced recovery with minimally invasive valve surgery.

Purpose Of Review: Patients with advanced age and frailty require interventions for structural heart disease at an increasing rate. These patients typically experience higher rates of postoperative morbidity, mortality and prolonged hospital length of stay, loss of independence as well as associated increased costs to the healthcare system. Therefore, it is becoming critically important to raise awareness and develop strategies to improve clinical outcomes in the contemporary, high-risk patient population undergoing cardiacprocedures.

The Perceval Sutureless Bioprosthetic Aortic Valve: Evolution of Surgical Valve Technology.

Objective: The surgical treatment of aortic stenosis continues to evolve, and sutureless aortic valve replacement (SUAVR) is an emerging technology. With the Perceval S (Corcym, London, UK) as the only true sutureless valve on the market, the objective of this review is to analyze the current literature on Perceval S. Focusing on valve design and deployment as well as applications of the technology for challenging pathology, clinical outcomes are assessed, including a comparison with transcatheter AVR (TAVR).

Cardiac surgery elicits pericardial inflammatory responses that are distinct compared with postcardiopulmonary bypass systemic inflammation.

Objectives: Cardiac surgery using cardiopulmonary bypass contributes to a robust systemic inflammatory process. Local intrapericardial postsurgical inflammation is believed to trigger important clinical implications, such as postoperative atrial fibrillation and postsurgical intrathoracic adhesions. Immune mediators in the pericardial space may underlie such complications.

Echocardiographic and clinical outcomes following beating heart NeoChord DS1000 mitral valve repair: a single centre case series.

Background: The NeoChord DS1000 system implants artificial neochords transapically, through a left mini-thoracotomy to treat degenerative mitral valve regurgitation (MR). Performed without cardiopulmonary bypass, neochord implantation and length adjustment is guided by transesophageal echocardiography. We describe imaging and clinical outcomes for a single center case series using this innovative device platform.

Comprehensive characterization of the postoperative pericardial inflammatory response: Potential implications for clinical outcomes.

Objective: There is a paucity of data on the inflammatory response that takes place in the pericardial space after cardiac surgery. This study provides a comprehensive assessment of the local postoperative inflammatory response.

Methods: Forty-three patients underwent cardiotomy, where native pericardial fluid was aspirated and compared with postoperative pericardial effluent collected at 4, 24, and 48 hours' postcardiopulmonary bypass.

A Systematic Review and Meta-Analysis of Robot-Assisted Mitral Valve Repair.

Objective: Robot-assisted surgery is a minimally invasive approach for repairing the mitral valve. This study aimed to assess its safety and clinical efficacy when compared with conventional sternotomy, partial sternotomy, and right minithoracotomy.

Methods: A systematic review of peer-reviewed studies comparing robot-assisted mitral valve repair with conventional sternotomy, partial sternotomy, and right minithoracotomy was conducted following Cochrane Collaboration guidelines.

Minimally Invasive Beating Heart Mitral Valve Repair in a Patient With Connective Tissue Disease at Prohibitive Risk for Redo Sternotomy.

Sternal reentry when the ascending aorta is adherent to the posterior table of the sternum is associated with substantial risk. A minimally invasive right thoracotomy beating heart approach is an alternative when the aorta cannot be cross-clamped. This report details this technique for a complex reoperative mitral valve repair procedure performed in a patient with connective tissue disease who had required multiple aortic operations and presented with heart failure and severe functional mitral regurgitation.
