BACKGROUND: Kartagener's syndrome, a rare autosomal recessive genetic disorder, is characterized by primary ciliary dyskinesia (PCD), resulting in defective cilia function in the respiratory tract and fallopian tubes. CASE PRESENTATION: This case report discusses a 23-year-old female with Kartagener's syndrome, bronchiectasis, and cardiac involvement, who presented with shortness of breath, cough, and syncope. Notably, she received home oxygen therapy but became exhausted, leading to loss of consciousness...

OBJECTIVES: The objective of this study was primarily to compare 4D flow magnetic resonance imaging (MRI) metrics in the ascending aorta (AA) of patients with right-left fusion type bicuspid aortic valve (RL-BAV) and repaired CoA to RL-BAV without CoA. Metrics of patients with RL-BAV were also compared to the matched group of patients with common tricuspid aortic valve (TAV). METHODS: 11 patients with RL-BAV and CoA, 11 patients with RL-BAV without CoA, and 22 controls with TAV, were investigated...

INTRODUCTION: The management of cardiopulmonary bypass (CPB) is still challenging in certain circumstances, especially for patients with anatomical variations. This challenge is even harder for reoperations, which are associated with increased morbidity and mortality risk. CASE REPORT: We describe a minimally invasive, beating-heart redo tricuspid valve replacement in a 71-years old woman with persistent left superior vena cava. DISCUSSION: Preoperative planning via CT-scan, teamwork and custom-made management of CPB are crucial for reoperations with anatomical variations...

The prevalence of coronary artery disease (CAD) in bicuspid aortic valve (BAV) patients is a debatable topic. Several studies have indicated that BAV patients have a lower prevalence of CAD compared with patients with a tricuspid aortic valve (TAV), but the effects of age and gender have not always been considered. This systematic review provides an overview of articles which report on CAD in BAV and TAV patients. Searches were executed in April 2021 and January 2022 according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-analyses) guidelines in three online databases: Medline, Embase, and Scopus...

BACKGROUND: The survival of patients with neuroendocrine tumors has substantially improved with modern treatment options. Although the associated carcinoid syndrome can be diagnosed early and controlled effectively, cardiologists still encounter patients with cardiac manifestations, particularly among individuals with persistently high levels of vasoactive mediators. Treatment options have been limited to surgical valve replacement in fully manifested disease. Since surgery is not always feasible, transcatheter valve implantation is becoming an interesting alternative...

AIMS: Evaluation of left and right ventricular longitudinal systolic function may enhance risk stratification following aortic valve replacement (AVR). The study objective was to evaluate the changes in left and right ventricular longitudinal systolic function and RV-pulmonary artery (RV-PA) coupling from baseline to 30-days and 1-year after aortic valve replacement (AVR). METHODS AND RESULTS: LV longitudinal strain (LS), tricuspid annulus plane systolic excursion (TAPSE), and RV-PA coupling were evaluated in patients from the PARTNER-2A surgical AVR (SAVR) arm (n=985) and from the PARTNER-2 SAPIEN-3 registry (n=719)...

Ebstein anomaly is a myopathy of the right ventricle characterized by failure of tricuspid valve delamination with accompanying tricuspid regurgitation. Its rarity, considerable anatomic variability, and frequent absence of symptoms can make the timing of surgery challenging. Contemporary tricuspid repair techniques can be performed with low mortality and bidirectional cavopulmonary anastomosis reduces the risk of operation when right ventricular function is poor. Here, we present a patient who presented late for surgery, failed high-risk conventional surgery and required heart transplantation...

BACKGROUND AND OBJECTIVES: Venovenous Extracorporeal Membrane Oxygenation (VV ECMO) provides respiratory support to patients with severe lung disease failing conventional medical therapy. An essential component of the ECMO circuit are the cannulas, which drain and return blood into the body. Despite being anchored to the patient to prevent accidental removal, minor cannula movements are common during ECMO. The clinical and haemodynamic consequences of these small movements are currently unclear...

BACKGROUND: Tricuspid regurgitation (TR) is associated with increased morbidity and mortality. As many elderly TR patients are deemed inoperable, transcatheter edge-to-edge repair (T-TEER) is arising as a viable treatment option. Though procedural safety aspects seem excellent, long-term risks cannot be ignored, including the feasibility of cardiac pacing by endovascular lead implantation at a later time, as well as T-TEER device-related infective endocarditis (IE), in the context of systemic infection...

OBJECTIVES: The progressive increase in the use of implantable electronic devices, vascular access for dialysis and the increased life expectancy of patients with congenital heart diseases has led in recent years to a considerable number of right-side infective endocarditis, especially of the tricuspid valve. Although current guidelines recommend tricuspid valve repair for native tricuspid valve endocarditis, the percentage of valve replacements remains very high in numerous studies. The aim of our study is to analyze our experience in the treatment of tricuspid valve endocarditis with a reparative approach...

INTRODUCTION: The Gerbode defect is an infrequent cardiac anomaly, with an incidence below 1 % in current worldwide literature. It consists of a communication between the left ventricle and right atrium in the membranous septum with consequential hemodynamical and structural heart changes and can present as either congenital or acquired. The concomitant affectation of the tricuspid valve poses its difficulty as a diagnostic and therapeutical challenge. PRESENTATION OF CASE: This case report presents a 27-year-old patient with an incidental finding of congenital Gerbode defect with hemodynamical repercussion during surgical treatment for multidisciplinary management in the context of open thoracic trauma...

OBJECTIVES: Ebstein anomaly is a congenital defect characterized by a lack of delamination and apical displacement of the tricuspid valve, tricuspid insufficiency, right atrial enlargement, and ventricular dysfunction. To analyze the results and evolution of the different surgical strategies, data were collected from 45 patients operated on during 1990-2018. Twenty-six patients were included with a median age at initial surgery of 11.3 years (range: 13 days-18.6 years). METHOD: Procedures were plastic 10 patients (38%), cone technique reconstruction 11 (42%), and replacement 5 (19%)...

BACKGROUND: This meta-analysis compared survival outcomes among patients experiencing improvement in untreated significant tricuspid regurgitation (TR) following transcatheter aortic valve replacement (TAVR) for severe aortic stenosis, in contrast to those without improvement. METHODS: MEDLINE and EMBASE were searched through January 2024. Pooled hazard ratios (HR) with 95% confidence intervals (CI) were computed. Employing network meta-analysis, a comparison involving four post-procedural TR categories (improved, no improvement, worsened, and no change) was executed...

BACKGROUND: This study was performed to determine cusp causes of aortic regurgitation in patients with tricuspid aortic valves without significant aortic dilatation and define cusp pathologies amenable to surgical repair (aortic valve repair [AVr]) versus aortic valve replacement. METHODS AND RESULTS: We retrospectively reviewed surgical reports of consecutive adults with tricuspid aortic valves undergoing surgery for clinically significant aortic regurgitation within a prospective registry from January 2005 to September 2019...

OBJECTIVES: Symptomatic neonates and infants with Ebstein Anomaly (EA) require complex management. A group of experts was commissioned by the American Association for Thoracic Surgery to provide a framework on this topic focusing on risk stratification and management. METHODS: The EA Clinical Congenital Practice Standards Committee is a multinational and multidisciplinary group of surgeons and cardiologists with expertise in EA. A citation search in PubMed, Embase, Scopus, and Web of Science was performed using key words related to EA...

Leadless pacemakers offer the opportunity to avoid transvenous hardware among patients with tricuspid valve prostheses. We present the first case of a helix-based fixation leadless pacemaker implanted through valve-in-valve tricuspid prostheses in a 43-year-old female with extensive prior cardiac history. At the time of presentation, epicardial pacing was no longer a viable option in the setting of pacemaker dependence. Placement of a helix-fixed, leadless right ventricular pacemaker was performed as a bridge to dual-chamber leadless pacing...
