[Right Coronary Artery Stenosis Demonstrated a Few Hours After Surgical Aortic Valve Replacement: Report of a Case].

Some cases of coronary artery occlusion by prosthetic valves after surgical aortic valve replacement (SAVR) may be diagnosed and treated during operation if it is difficult to be separated from cardiopulmonary bypass. We present a case of a 74-year-old woman with symptomatic aortic stenosis due to bicuspid valve and a narrow aortic valve annulus. SAVR was considered to be feasible over transcatheter aortic valve implantation given her anatomy and frailty.

Reproductive health among women of child-bearing age after surgery for rheumatic heart disease in Rwanda.

Objective: To determine maternal and fetal outcomes in postoperative women with rheumatic heart disease who become pregnant after valve surgery and evaluate current anticoagulation management during pregnancy.

Methods: Data from the Rwandan rheumatic heart disease cardiac surgical registry identified all female patients who underwent valve surgery before or during childbearing age since 2006. In total, 136 participants completed a mixed-methods questionnaire detailing each pregnancy after surgery, including anticoagulation regimen and outcomes.

A case of hybrid robotic-assisted coronary artery bypass grafting and valve-in-valve transcatheter aortic valve replacement.

Unlabelled: We report a hybrid procedure of robotic-assisted coronary artery bypass grafting and transcatheter aortic valve-in-valve implantation for left main disease and prosthetic aortic valve stenosis. Robotic-assisted coronary artery bypass grafting using a left internal mammary artery graft was preferred to percutaneous coronary intervention because of the complex anatomy of the coronary lesion and concerns about dual antiplatelet therapy tolerance. This was followed by a valve-in-valve procedure five days later, allowing the patient to be discharged the next day.

Case report: pseudoaneurysm of left ventricle secondary to infective endocarditis complicated by cardiac rupture-a multimodality imaging approach.

Background: Pseudoaneurysm (PSA) of the left ventricle (LV) is a rare peri-annular complication of infective endocarditis (IE), and it is associated with high risk of free wall rupture. The diagnosis is challenging because the exact incidence and the pathogenesis are still unclear.

Case Summary: A 69-year-old lady underwent prosthetic mitral valve replacement for IE secondary to sepsis complicated by multiple embolizations.

Structural heart transcatheter interventions in orthotopic cardiac transplant and left ventricular assist devices recipients: A nationwide study.

Background: The current incidence and outcomes of structural transcatheter procedures in heart transplant (HTx) recipients and left-ventricular assist devices (LVAD) carriers is unknown.

Aims: To provide insights on structural transcatheter procedures performed across HTx and LVAD patients in Spain.

Methods: Multicenter, ambispective, observational nationwide registry.

Artificial Neochordae for Tricuspid Valve Repair in Adults: A Review.

Expanded polytetrafluoroethylene (ePTFE) neochordae are predominantly used for mitral valve repair (MVr), while the frequency of their employment in tricuspid valve surgery is not well assessed. We have performed a review of the available literature to verify incidence, indications, techniques, and outcomes of the use of artificial neochordae in a variety of tricuspid valve pathologies. We found a total of 57 articles reporting the use of ePTFE sutures in patients in whom tricuspid valve repair (TVr) was performed.

Concomitant tricuspid valve surgery in patients with significant tricuspid regurgitation undergoing left ventricular assist device implantation: A systematic review and meta-analysis.

Background: Significant tricuspid regurgitation (TR) is a predictor of right heart failure (RHF) and increased mortality following left ventricular assist device (LVAD) implantation, however the benefit of tricuspid valve surgery (TVS) at the time of LVAD implantation remains unclear. This study compares early and late mortality and RHF outcomes in patients with significant TR undergoing LVAD implantation with and without concomitant TVS.

Methods: A systematic search of four electronic databases was conducted for studies comparing patients with moderate or severe TR undergoing LVAD implantation with or without concomitant TVS.

Mitral valve replacement in young patients: review and current challenges.

Mitral valve repair is the ideal intervention for mitral valve disease with excellent long-term survival comparable to the age-matched general population. When the mitral valve is not repairable, mechanical prostheses may be associated with improved survival as compared with biological prostheses. Newer mechanical and biological valve prostheses have the potential to improve outcomes following mitral valve replacement in young patients.

Angina pectoris? Fake news: a case report of infective endocarditis with giant aortic root abscess detected by cardiac magnetic resonance imaging.

Background: Infective endocarditis (IE) is a rare disease associated with high mortality rates. Clinical presentation is highly variable with a time interval between first onset of symptoms and diagnosis > 1 month in 25% of patients. We present a case of aortic valve endocarditis with aortic root abscess (ARA) with chest pain and ischaemic changes on the electrocardiogram (ECG).

Review of Machine Learning Techniques in Soft Tissue Biomechanics and Biomaterials.

Background And Objective: Advanced material models and material characterization of soft biological tissues play an essential role in pre-surgical planning for vascular surgeries and transcatheter interventions. Recent advances in heart valve engineering, medical device and patch design are built upon these models. Furthermore, understanding vascular growth and remodeling in native and tissue-engineered vascular biomaterials, as well as designing and testing drugs on soft tissue, are crucial aspects of predictive regenerative medicine.

Secondary tricuspid regurgitation: incidence, types, and outcomes in atrial fibrillation vs. sinus rhythm.

Background And Aims: Incidence and types of secondary tricuspid regurgitation (TR) are not well defined in atrial fibrillation (AFib) and sinus rhythm (SR). Atrial secondary TR (A-STR) is associated with pre-existing AFib; however, close to 50% of patients with A-STR do not have AFib. The aim of this study was to assess incidence, types, and outcomes of ≥ moderate TR in AFib vs.

Elevated myocardial extracellular volume fraction is associated with the development of conduction pathway defects following transcatheter aortic valve replacement.

Background: Transcatheter aortic valve replacement (TAVR) has become an established method of aortic stenosis treatment but suffers from the risk of heart block and pacemaker requirement. Risk stratification for patients who may develop heart block remains imperfect. Simultaneously, myocardial fibrosis as measured by cardiac magnetic resonance imaging (CMR) has been demonstrated as a prognostic indicator of ventricular recovery and mortality following TAVR.

[Cluster Analysis and Ablation Success Rate in Atrial Fibrillation Patients Undergoing Catheter Ablation].

Objective: Atrial fibrillation (AF) is a disease of high heterogeneity, and the association between AF phenotypes and the outcome of different catheter ablation strategies remains unclear. Conventional classification of AF (e.g.

Thrombogenic Risk Assessment of Transcatheter Prosthetic Heart Valves Using a Fluid-Structure Interaction Approach.

Background And Objective: Prosthetic heart valve interventions such as TAVR have surged over the past decade, but the associated complication of long-term, life-threatening thrombotic events continues to undermine patient outcomes. Thus, improving thrombogenic risk analysis of TAVR devices is crucial. In vitro studies for thrombogenicity are typically difficult to perform.

Left versus right ventricular pacing during TAVR and balloon aortic valvuloplasty: A systematic review and meta-analysis.

Introduction: While right ventricular pacing (RVP) is the conventional temporary pacing modality used for transcatheter aortic valve replacement (TAVR), this approach possesses inherent risks and procedural challenges. We aim to assess and compare the safety and efficacy of left ventricular pacing (LVP) and RVP during TAVR and balloon aortic valvuloplasty (BAV).

Methods: Following PRISMA guidelines, a comprehensive literature search was conducted in four databases from inception to December 15th, 2023.

Investigations of Differential Hypoxemia During Venoarterial Membrane Oxygenation with and Without Impella Support.

Purpose: Venoarterial extracorporeal membrane oxygenation (VA ECMO) is used in patients with refractory cardiac or cardio-pulmonary failure. Native ventricular output interacts with VA ECMO flow and may hinder sufficient oxygenation to the heart and the brain. Further on, VA ECMO leads to afterload increase requiring ventricular unloading.
