Robotic Transjugular Transcatheter Tricuspid Valve Replacement

Valvular heart disease (VHD), caused by abnormalities in heart valves, can lead to severe complications such as heart failure and death, with approximately 220 million affected patients worldwide. The prevalence of VHD continues to grow alongside the aging global population. Transcatheter heart valve interventions have emerged as minimally invasive alternatives, offering benefits like shorter recovery times and reduced discomfort. However, current manual catheter-based techniques are complex, highly dependent on clinicians' expertise, and involve significant physical risk due to prolonged exposure to X-ray radiation and cumbersome protective gear. To address these challenges, a novel, universal intracardiac robotic system is proposed to improve precision, safety, and procedural efficiency. This system integrates a high-dexterity, load-capacity catheter instrument, a modular concentric robotic platform, and an augmented reality (AR) navigation interface. The catheter's design balances flexibility for navigating complex intracardiac paths with the rigidity needed for device deployment. The robotic platform's modular architecture enhances versatility, enabling control across various procedures and anatomical variations, while the AR system facilitates intuitive preoperative planning and real-time intraoperative guidance through multimodal image fusion. The core innovation lies in overcoming existing limitations: balancing catheter flexibility and load capacity, expanding robotic system adaptability for different valve procedures, and improving integration with imaging modalities like computed tomography, transesophageal echocardiogram, and fluoroscopy. The project aims to develop sophisticated models for instrument design, control strategies for multi-instrument coordination, and advanced navigation tools. These technological advancements are intended to elevate the clinical utility of robotic intracardiac interventions, making them safer, more efficient, and easier to adopt widely. By establishing a systematic approach for intelligent, multimodal, robotic-assisted valvular procedures, this work promises significant contributions to minimally invasive cardiology and holds substantial potential for clinical translation.

LuX-Valve Plus System for Severe or Greater Tricuspid Regurgitation

This clinical trial aims to evaluate the safety and effectiveness of the Transvenous Artificial Tricuspid Valve System, LuX-Valve Plus System, Jenscare Scientific Co., Ltd. The study population consists of high-risk patients with severe or greater tricuspid regurgitation (TR) who are ineligible for surgical intervention and have demonstrated inadequate response to optimized medical therapy (OMT). This is a prospective, multicenter, randomized controlled trial. A total of 111 subjects who meet all inclusion criteria and none of the exclusion criteria will be enrolled. Participants will be randomized in a 2:1 ratio to one of the following groups: Treatment Group: Transvenous Artificial Tricuspid Valve System implantation + OMT Control Group: OMT alone All subjects will undergo serial follow-up assessments pre-treatment, during the treatment period, and post-procedure at 30 days, 3 months, 6 months, 1 year, and annually through 2-5 years. A summary report will be submitted to the regulatory authority at the 6-month time point. Subjects in the treatment group will have one extra follow-up visit at 7 days ± 3 days post-procedure or prior to discharge (whichever occurs first).

Efficacy of Verciguat in TR and RV Failure

The goal of this clinical trial is to learn if the drug vericiguat works to improve right heart function in patients with worsening heart failure who have reduced left ventricular function. It will also examine the effects of the drug on tricuspid regurgitation (TR) and overall clinical outcomes. The main questions it aims to answer are: Does vericiguat improve right ventricular (RV) function and reduce tricuspid regurgitation (TR)? Does vericiguat reduce the risk of major adverse cardiovascular events (MACE), such as heart failure hospitalizations and cardiovascular death? Does vericiguat improve participants' exercise capacity, quality of life, and renal function? Researchers have previously seen the benefits of vericiguat in the large-scale VICTORIA trial for worsening heart failure, and it is hypothesized that improvements in right heart function play a key role. This study aims to confirm these specific benefits. Participants will: Take vericiguat as prescribed during the study period. Undergo echocardiograms at enrollment and at 9 months to assess right heart function. Complete questionnaires (KCCQ-12) and walking tests (6MWT) to evaluate quality of life and exercise capacity. Provide blood samples to monitor NTproBNP levels and renal function (creatinine).

Natural History of Atrial Fibrillation-Induced Tricuspid Valve Remodeling in the Absence of Significant Tricuspid Regurgitation: A Three-Dimensional Echocardiographic Study

This is a prospective, observational, multicenter study aimed at characterizing tricuspid valve remodeling in patients with atrial fibrillation (AF) without significant tricuspid regurgitation (TR), in relation to AF burden progression.

Efficacy of Early Rhythm Control in AF With TR Patients

Atrial fibrillation is frequently accompanied by tricuspid regurgitation and may contribute to right atrial and tricuspid annular remodeling, leading to progression of tricuspid regurgitation and adverse clinical outcomes. However, whether early rhythm control improves prognosis in patients with atrial fibrillation and tricuspid regurgitation remains unclear. This study will compare early rhythm control with usual care in these patients, using a composite outcome of cardiac death, heart failure admission, stroke, and tricuspid valve surgery.

PASCAL Precision-GDMT Registry

The goal of this observational study is to demonstrate that successful tricuspid valve repair with the PASCAL Precision System in participants with at least severe tricuspid insufficiency and left ventricular dysfunction will be associated with an improvement in up-titration of guideline-directed medical therapy (GDMT). The main question it aims to answer is: Does the tricuspid insufficiency repair with the Pascal Precision System increases the dose of the medications used for heart failure therapy in the study population 12 months after tricuspid repair, as compared to the dose taken at baseline. Participants undergoing tricuspid repair and fulfilling all inclusion/exclusion criteria will be asked to answer heart failure assessment as well as quality of life questionnaires at baseline and at 12 months post intervention. Medication monitoring will be performed throughout the study.

DELINEATE-Prospective

Heart disease is the leading cause of death in the United States, and echocardiography (or "echo") is the most common way doctors look at the heart. Echo is safe, painless, and can detect major heart problems, including weak heart pumping and valve disease. Valve disease, especially aortic stenosis (narrowing) and mitral regurgitation (leakage), is common in older adults but often goes undiagnosed. While echo is the main tool for finding valve problems, it takes time, requires expert training, and results can vary between readers. Recent advances in artificial intelligence (AI), especially deep learning (DL), have shown promise in automatically analyzing heart images. However, past research hasn't fully tackled key echo techniques-like color Doppler and spectral Doppler-that are crucial for measuring how blood moves through heart valves. AI tools also face challenges in being used in everyday medical practice because of workflow issues, lack of real-world testing, and concerns about how the algorithms make decisions. At Columbia University Irving Medical Center, researchers have built a large database of heart tests over the last six years and developed AI programs to analyze echocardiograms. The current study will test whether providing AI analysis to cardiologists in real time during echo reading can make the process faster and more consistent.

Impact of Severe Tricuspid Regurgitation Correction on Gut Microbiota and Gastrointestinal Function

Tricuspid regurgitation (TR) is gaining increasing attention within the cardiological community due to its poor prognosis, challenging clinical presentation and difficult treatment. TR causes decreased forward cardiac output and increased intravascular pressure upstream, which lead to peripheral oedema, ascites, hepatic congestion and kidney failure. The microbiota is also getting increasing attention and changes in microbiota have been already associated with cardiovascular disease. The impact of hemodynamic effects of TR on the gut microbiota however is still unknown. Patients affected by TR frequently complain abdominal distension and anorexia. We hypothesize that, due to increased venous congestion, TR may induce impaired gut function with modification in the microbiota and that TR correction may induce reverse changes. This study will enroll patients treated with Transcatheter Tricuspid Edge-to-Edge Repair (T-TEER) at the Valve Center of San Raffaele Hospital due to severe TR. In addition to the standard of care, before T-TEER, for all patients 2 additional blood samples, 1 urine and 1 fecal sample will be collected. 3 months after the procedure, all patients will be re-assessed at the Valve Center outpatient clinic as standard of care. At this stage for all patients 2 blood samples, 1 urine and 1 fecal sample will be collected again for the purpose of the study. The microbiota metabolites of patients after 3 months from the procedure will be compared to those at baseline according to the degrees of residual TR. To assess the reproducibility of the microbiota results and to explore an intrinsic short-term variation in microbiome composition within single patients, a subgroup of 30 patients will undergo a low intervention substudy repeating the measurements (2 blood, 1 urine and 1 fecal) within 10 days, both at baseline and at follow-up.
