Importance of Point-of-Care Ultrasound for Early Detection of Valvular and Cardiac Diseases (IMPROVE)

Heart valve disease and weakened heart muscle (left ventricular systolic dysfunction) are common in older adults and often go undetected until serious complications such as heart failure develop. Detection currently depends on a clinician hearing a murmur and then ordering an echocardiogram, which is easily missed or delayed. This study tests whether a brief, artificial intelligence (AI)-guided handheld heart ultrasound - point-of-care ultrasound, or POCUS - performed by trained clinic staff during a routine visit identifies these conditions earlier than usual care. Primary care and geriatrics providers, rather than individual patients, are assigned by chance to one of two groups. Patients seen by providers in the AI-ultrasound group are offered a POCUS scan and a one-time blood test at their regular visit, and are referred for a confirmatory echocardiogram if the scan is abnormal. Patients seen by providers in the usual care group receive standard clinic care. Researchers will compare how often previously undiagnosed structural heart disease is newly identified in each group.

Exploratory Study of the Diagnostic Potential of an Innovative Thoracic Vibration Analysis Technique

Heart and lung disease are two major causes of hospitalisation and mortality in France (4-8). Together, these two diseases affect several million people in France, either acutely or chronically. They represent a major public health problem in social and economic terms. Diagnosis of these disorders is often delayed, with acute decompensation preceded by a period of frustrating, non-specific clinical signs (9-12), which delay their discovery. Screening for these conditions in their early stages or diagnosing them in their acute form is crucial, but remains difficult because it requires multiple investigations that are costly and time-consuming (biology, radiology, ECG, etc.). The difficulty of diagnosis, the progressive profile and the ever-increasing frequency of these conditions (environmental and socio-economic factors) have considerably altered the landscape of medical emergencies and contributed to their difficulty. The availability of a non-invasive technique capable of diagnosing both cardiac and pulmonary disorders without the help of an expert, without direct contact with the patient and without requiring his or her active participation, would be a major advance. Technological innovations in all fields have always helped to improve patient care.The recent emergence of telemedicine and POCT(US) connected objects (point of care testing, point of care ultrasound)(13,14) is a good illustration of this. A new technique using ultrasound, developed by the Langevin Institute (Surface Camera Motion) and supported by the start-up Austral Diagnostics, makes it possible, without direct contact with the subject, to record the propagation of thoracic vibrations induced by the functioning of the heart pump and respiratory mechanics.Consequently, any anomaly in the functioning of these organs can cause a change in the thoracic vibration regime and its propagation. This completely new technique for exploring thoracic vibrations provides a particularly rich signal that has not yet been explored. Under these conditions, the signatures associated with cardiac and/or pulmonary pathologies are not yet perfectly defined.Furthermore, the diagnostic potential of this new technique in the early or acute phases of cardiopulmonary pathologies remains to be assessed. In this prospective study, we propose to explore the signatures produced by this signal in various cardiac and respiratory pathologies. The aim is To identify the discriminating criteria of the SMC signal that enable cardiac and pulmonary pathologies to be detected compared with a group of healthy subjects.

Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation

Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Plan (MAC CAP). Subjects in the Randomized cohort were randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts were receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) was to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial would provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System would be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who were not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and were also not suitable for transcatheter repair with MitraClip, would be enrolled in the Non-repairable cohort. Subjects would be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.

The CardioClip Study

The CardioClip study is exploring the use of a wireless sensor to monitor pressure in the pulmonary artery. This sensor is inserted much like the mTEER procedure, a non-surgical method through a vein in the groin. The investigators want to find out if the sensor, by constantly sending information about heart function, can help improve patient outcomes. This means doctors could adjust medications based on real-time pressure changes detected by the sensor. The results from this study will help pave the way for future trials, asking if using these wireless sensors could benefit people with valve disease and heart failure.

The Role of cardIac magNeTic rEsonance in surGical Decision Making in Patients With Severe pRimAry miTral rEgurgitation

Mitral regurgitation (MR) is the second most frequent valvular heart disease and the second most frequent indication for valve surgery in Europe. The management of patients with MV prolapse (MVP) and severe MR is mainly guided by symptoms, left ventricular (LV) dimensions and ejection fraction (EF), pulmonary artery systolic pressure (PASP) and atrial fibrillation (AF) occurrence. According to the ESC/EACTS guidelines, surgical treatment of severe primary MR is indicated (recommendation Class I, Level B) in case of: * symptomatic patients considered operable by the Heart Team; * asymptomatic patients with LV dysfunction, intended as a LVEF ≤ 60% and/or LV end-systolic diameter (LVESD) ≥ 40 mm or LVESD indexed for body mass area (LVESDi) ≥ 20 mm/m2; * low-risk asymptomatic patients without LV dysfunction (LVEF \> 60%, LVESD \< 40 mm, LVESDi \< 20 mm/m2) when a durable result is likely, if at least 3 of the following criteria are fulfilled: * AF secondary to MR; * PASP value at rest \> 50 mmHg; * significant left atrium (LA) dilation, intended as LA volume index ≥ 60 mL/m2 or diameter ≥ 55 mm * concomitant secondary tricuspid regurgitation ≥ moderate. Surgery should be considered (recommendation Class IIa, Level B) in asymptomatic patients with preserved LV function (LVEF \> 60%, LVESD \< 40 mm, LVESDi \< 20 mm/m2), when one of the following findings is present1: * AF secondary to MR; * PASP value at rest \> 50 mmHg; * LA volume index ≥ 60 mL/m2 or diameter ≥ 55 mm, provided surgical risk is low, surgery is performed in a Heart Valve Center and a durable MV repair is likely. Preliminary data suggest that in patients with MVP, especially with Barlow's disease phenotype, left-sided chambers' enlargement and functional impairment may be disproportionate related to MR grade. Indeed, patients with BD and ≤ mild-to-moderate MR show larger LA and LV dimensions as compared to controls matched for age, gender and cardiovascular risk factors. These findings challenge the assumption that LA and LV remodeling is a direct effect of volume overload, with possible implications regarding the indication for MV intervention. On the other hand, low mortality and good durability of valve repair has led some experienced centers to perform also early surgery, namely in any asymptomatic patient with severe MR, normal LV size and function, regular sinus rhythm, normal PASP and normal LA size, as long as surgical risk is very low and likelihood of successful valve repair is high. However, some studies have demonstrated that asymptomatic patients with severe degenerative MR can be safely followed up in experienced hands and remain free of indications for surgery for extensive periods of time. A watchful waiting strategy resulted in timely referral to surgery, excellent long-term survival, and good surgical outcomes, though requiring careful and active surveillance. Several authors agree that prospective randomized trials comparing active surveillance and early elective surgery are needed. There are also data suggesting that MR quantification by CMR has better discriminative power in identifying asymptomatic patients with degenerative MR and adverse outcomes as compared to the echocardiographic-derived integrative approach. Further prospective studies are necessary to validate these preliminary findings.

The registry primarily focuses on patients treated with TMVR in real-world clinical practice. Patients evaluated for TMVR but not undergoing the procedure are no longer systematically included. Historical data may include such patients who subsequently underwent alternative treatments, including transcatheter edge-to-edge repair, mitral valve surgery, or medical/conservative therapy.

LEFT ATRIAL MONITORING IN PATIENTS BEFORE AND AFTER MITRAL SURGERY - LAMBDA STUDY

Mitral valve leakage, or mitral regurgitation (MR), is associated with heart failure symptoms including shortness of breath, fatigue, irregular heart rate. When left untreated, it may cause death. Patients with MR can be divided in two broad groups: those with primary MR, caused by disease of the mitral valve structures, and those with secondary MR, due to dilation of the heart chambers. Our study focuses on patients with primary MR. The standard treatment for severe symptomatic primary MR is mitral valve surgery, a type of open-heart surgery. The outcomes following this procedure are excellent, however, a subset of patients continue to experience heart failure symptoms after surgery due to very high pressures in the heart, more specifically in the left atrium, which is one of the four heart chambers. This is called functional mitral stenosis (FMS). Previous studies have shown that creating a small opening between the left and right atria can help relieve the pressure inside the left atrium. We would like to determine whether creating this opening between the two atria at the time of mitral valve surgery can help prevent FMS. To answer this question, we will study two groups of patients who need mitral valve surgery for primary MR. The first group will undergo mitral valve surgery, along with the creation of the opening between the two atria. The second group will undergo mitral valve surgery alone. We will then compare the outcomes between both groups, namely with regards to their heart failure symptoms after open-heart surgery.
