Infective endocarditis is a rare but life-threatening condition, occasionally linked to diverse immunologic manifestations, including mixed cryoglobulinemia. This can lead to cryoglobulinemic vasculitis, which has the potential for widespread organ damage. Although some cases have highlighted the relationship between infective endocarditis and cryoglobulinemic vasculitis, no comprehensive epidemiological evaluation or optimal treatment strategies have been advanced for such a combination. We present a case of methicillin-sensitive Staphylococcus aureus infective endocarditis associated with cryoglobulinemic vasculitis and conduct a literature review to compare management and outcomes in similar cases. Our patient presented with classical Meltzer\'s triad and mild renal involvement. Cryoimmunofixation confirmed type III cryoglobulinemia, and serum cytokines showed elevated IL-6 levels. The differential diagnosis included infective endocarditis and chronic active hepatitis C virus infection. Rapid symptom resolution after antibiotic treatment identified infective endocarditis as the likely cause of cryoglobulinemic vasculitis. Our case and review of the literature highlight that early identification of the cause of cryoglobulinemic vasculitis is crucial for selecting appropriate treatment and preventing recurrence or morbidity.

UNASSIGNED: Intervention for tricuspid regurgitation (TR) tends to happen concurrently with and is addressed during mitral valve surgery. Isolated TR interventions, however, are not unusual and are becoming more common. The purpose of this study was to provide a general overview of the transcatheter tricuspid valve implantation (TTVI) devices, taking into account the several design variations, and to unify the implantation technique, existing clinical results, and potential future directions for TR replacement therapy.
UNASSIGNED: The major databases, namely Pubmed via Medline, Embase, and Cochrane library, were systematically searched from the date of conception until 10 February 2023, in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) standards.
UNASSIGNED: Eleven studies were isolated from a total cohort of 5842 publications. All the transcatheter tricuspid prostheses were circular in design yet categorized into annular tricuspid valve implantation (ATVI) and caval valve implantation (CAVI) groups. Bleeding (25.2%), severe access site and vascular issues requiring intervention (5.8%), device migration or embolization (3.6%), and paravalvular leak (38%) are among the early TTVI-related complications that have been observed. The CAVI group experienced 3 of 28 bleeding cases and 2 of 4 device migration cases.
UNASSIGNED: Following the intervention with a transcatheter tricuspid prosthesis, this review discovered an early favorable outcome and a general improvement in heart failure symptoms. However, there was a lot of variation in their design, implantation technique, and early clinical outcomes. Understanding the design variations, difficulty of implantation and learning from this review\'s key findings could help with the future development of catheter-based tricuspid valves.

OBJECTIVE: Patients with severe tricuspid regurgitation (TR) are at risk for significant morbidity and mortality. Transcatheter tricuspid valve interventions (TTVI) may offer patients less invasive treatment alternatives to surgery. This review evaluates the most common class of device currently used worldwide to treat TR, tricuspid transcatheter edge-to-edge repair (T-TEER) and orthotopic transcatheter tricuspid valve replacement (TTVR), both of which are now approved in the USA and Europe.
RESULTS: The first pivotal randomized clinical trial, TRILUMINATE, demonstrated that T-TEER can safely reduce TR and is associated with improved health status outcomes. However, results of this trial have raised questions about whether this device can provide sufficient TR reduction to impact clinical outcomes. Orthotopic TTVR has recently gained attention with initial data suggesting near-complete TR elimination. The current review examines the technical features and anatomic limitations of the most commonly used devices for T-TEER and orthotopic TTVR, discusses the current clinical data for these devices, and offers a theoretical construct for device selection.

Tricuspid valve disease is an often underrecognized clinical problem that is associated with significant morbidity and mortality. Unfortunately, patients will often present late in their disease course with severe right-sided heart failure, pulmonary hypertension, and life-limiting symptoms that have few durable treatment options. Traditionally, the only treatment for tricuspid valve disease has been medical therapy or surgery; however, there have been increasing interest and success with the use of transcatheter tricuspid valve therapies over the past several years to treat patients with previously limited therapeutic options. The tricuspid valve is complex anatomically, lying adjacent to important anatomic structures such as the right coronary artery and the atrioventricular node, and is the passageway for permanent pacemaker leads into the right ventricle. In addition, the mechanism of tricuspid pathology varies widely between patients, which can be due to primary, secondary, or a combination of causes, meaning that it is not possible for 1 type of device to be suitable for treatment of all cases of tricuspid valve disease. To best visualize the pathology, several modalities of advanced cardiac imaging are often required, including transthoracic echocardiography, transesophageal echocardiography, cardiac computed tomography, and cardiac magnetic resonance imaging, to best visualize the pathology. This detailed imaging provides important information for choosing the ideal transcatheter treatment options for patients with tricuspid valve disease, taking into account the need for the lifetime management of the patient. This review highlights the important background, anatomic considerations, therapeutic options, and future directions with regard to treatment of tricuspid valve disease.

Brucellar endocarditis is a rare entity commonly described as a severe disease associated with high mortality and generally requiring valve surgery for cure. Right-sided endocarditis, a very uncommon presentation of brucellosis, may be associated with a better prognosis. We describe the case of a 72-year-old woman admitted to our institution with a persistent fever and multiple pulmonary infiltrates. Transthoracic echocardiography and serologic tests led to the diagnosis of brucellar tricuspid endocarditis. The patient responded favorably to antibiotic treatment alone and did not need surgery. Prolonged antibiotic therapy with a combination of drugs active on intracellular microorganisms in the absence of surgical treatment could be effective in brucellar tricuspid endocarditis when the valve is not severely damaged.

BACKGROUND: Haemophilus influenzae (HI) is an exceedingly rare cause of infective endocarditis (IE).
UNASSIGNED: We present a case of a 90-year-old female diagnosed with HI-IE involving the native tricuspid valve in the absence of traditional risk factors for right-sided endocarditis. She was treated with a 5-week course of IV Ampicillin from negative cultures and suffered no complications. We also conducted a thorough literature review through PubMed and Google Scholar, which yielded a mere 15 reported cases of HI-IE.
RESULTS: Fourteen of the reported HI-IE cases included epidemiological data, showing no gender predominance. The mean age of the subjects was 39.5, with the mitral valve being the most implicated (64%) and tricuspid valve involvement being rare (21%).
CONCLUSIONS: Native tricuspid valve IE is an uncommon entity, especially in the absence of IV drug use. Haemophilus influenzae is an extremely rare cause of IE, with a literature review showing merely 15 reported cases. This article cites the 16th case of HI-IE published in the literature.

Marfan syndrome (MFS) is a progressive connective tissue disease with a broad range of clinical manifestations. We sought to establish the spectrum of structural valvular abnormalities as cardiovascular involvement has been identified as the most life-threatening aspect of the syndrome. This was a systematic review with a meta-analysis of studies indexed in Medline from the inception of the database to November 7, 2022. Using the random-effects model, separate Forest and Galbraith plots were generated for each valvular abnormality assessed. Heterogeneity was assessed using the I2 statistics whilst funnel plots and Egger\'s test were used to assess for publication bias. From a total of 35 studies, a random-effects meta-analysis approximated the pooled summary estimates for the prevalence of cardiac valve abnormalities as mitral valve prolapse 65% (95% CI: 57%-73%); mitral valve regurgitation 40% (95% CI: 29%-51%); aortic valve regurgitation 40% (95% CI: 28%-53%); tricuspid valve prolapse 35% (95% CI: 15%-55%); and tricuspid valve regurgitation 43% (95% CI: 8%-78%). Only one study reported on the involvement of the pulmonary valve (pulmonary valve prolapse was estimated at 5.3% (95% CI: 1.9%-11.1%) in a cohort of 114 patients with MFS). We believe this study provides a description of the structural valvular disease spectrum and may help inform providers and patients in understanding the clinical history of MFS in the current treatment era with its increased life expectancy.

Tricuspid regurgitation is a common yet clinically complex problem, traditionally managed with diuretic therapy with no observable mortality benefit. Older studies on surgical intervention observed poor outcomes; however, this clinical reasoning predates current surgical approaches and novel transcatheter technology. The tricuspid apparatus is a complex structure that poses a technical challenge for surgeons and interventional cardiologists. Recent advances in surgical techniques and transcatheter therapy, particularly edge-to-edge repair devices, have demonstrated promising results for safety, reduction in tricuspid regurgitation, and improving quality of life. We review the clinical, imaging, and hemodynamic findings that characterize patients who should be considered for intervention, alongside the rapidly evolving approaches to interventional management.

BACKGROUND: Functional tricuspid regurgitation (TR) can develop either because of right ventricular (RV) remodeling (ventricular functional TR) and/or right atrial dilation (atrial functional TR).
OBJECTIVE: This meta-analysis aimed to investigate the association between right heart remodeling and long-term (>1 year) all-cause mortality in patients with significant TR (at least moderate, ≥2+).
METHODS: MEDLINE, ISI Web of Science, and SCOPUS databases were searched. Studies reporting data on at least 1 RV functional parameter and long-term all-cause mortality in patients with significant TR were included. This study was designed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) requirements.
RESULTS: Out of 8,902 studies, a total of 14 were included, enrolling 4,394 subjects. The duration of follow-up across the studies varied, ranging from a minimum of 15.5 months to a maximum of 73.2 months. Overall, long-term all-cause mortality was 31% (95% CI: 20%-41%; P ≤ 0.001). By means of meta-regression analyses, an inverse relation was found between tricuspid annular plane systolic excursion (11 studies enrolling 3,551 subjects, -6.3% [95% CI: -11.1% to -1.4%]; P = 0.011), RV fractional area change (9 studies, 2,975 subjects, -4.4% [95% CI: -5.9% to -2.9%]; P < 0.001), tricuspid annular dimension (7 studies, 2,986 subjects, -4.1% [95% CI: -7.6% to -0.5%]; P = 0.026), right atrial area (6 studies, 1,920 subjects, -1.9% [95% CI: -2.5% to -1.3%]; P < 0.001) and mortality.
CONCLUSIONS: RV dysfunction parameters are associated to worse clinical outcomes in patients with TR, whereas right atrial dilatation is linked to a better prognostic outcome. Further studies are needed to unravel the pathophysiological differences within the functional TR spectrum.

BACKGROUND: This study aims to investigate the effect of concomitant tricuspid valve surgery (TVS) during left ventricular assist device (LVAD) implantation due to the controversy over the clinical outcomes of concomitant TVS in patients undergoing LVAD.
METHODS: A systematic literature search was performed in PubMed and EMbase from the inception to 1 August 2023. Studies comparing outcomes in adult patients undergoing concomitant TVS during LVAD implantation (TVS group) and those who did not (no-TVS group) were included. The primary outcomes were right heart failure (RHF), right ventricular assist device (RVAD) implantation, and early mortality. All meta-analyses were performed using random-effects models, and a two-tailed P <0.05 was considered significant.
RESULTS: Twenty-one studies were included, and 16 of them were involved in the meta-analysis, with 660 patients in the TVS group and 1291 in the no-TVS group. Patients in the TVS group suffered from increased risks of RHF [risk ratios (RR)=1.31, 95% CI: 1.01-1.70, P =0.04; I2 =38%, pH =0.13), RVAD implantation (RR=1.56, 95% CI: 1.16-2.11, P =0.003; I2 =0%, pH =0.74), and early mortality (RR=1.61, 95% CI: 1.07-2.42, P =0.02; I2 =0%, pH =0.75). Besides, the increased risk of RHF holds true in patients with moderate to severe tricuspid regurgitation (RR=1.36, 95% CI: 1.04-1.78, P =0.02). TVS was associated with a prolonged cardiopulmonary bypass time. No significant differences in acute kidney injury, reoperation requirement, hospital length of stay, or ICU stay were observed.
CONCLUSIONS: Concomitant TVS failed to show benefits in patients undergoing LVAD, and it was associated with increased risks of RHF, RVAD implantation, and early mortality.
