NCT Number: NCT06241430
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.

Patients with heart failure suffer considerably. They experience an increased risk of death and are hospitalized with symptoms of heart failure frequently. Often times, heart failure results in abnormal function of the mitral valve (one of the key valves separating the heart's main pumping chamber - the left ventricle - from the left atrium, which collects oxygenated blood from arteries in the lung). This abnormal function causes the valve to leak - a condition called mitral regurgitation - that perpetuates and can exacerbate heart failure.
Recently, researchers have developed a procedure for patients with mitral regurgitation in the setting of heart failure called mitral transcatheter edge-to-edge repair (mTEER). In this procedure, a "clip" is deployed to grasp the mitral valve leaflet and re-approximate them, thereby reducing the amount of mitral regurgitation. This procedure is performed by accessing one of the large veins in the body and no surgical intervention is required. Patients typically recover within 24 hours and are discharged home without the prolonged recovery periods associated with traditional therapies for mitral regurgitation like open heart surgery and mitral valve repair or replacement. Moreover, the procedure is exceedingly safe, with a very low risk of significant adverse complications.
While mTEER reduces the risk of death and hospitalization for heart failure compared with the standard of care (i.e., medicines geared at improving heart function), many patients still suffer significant adverse events within a five year period. Accordingly, the investigators are interested in identifying strategies to further improve outcomes for patients with heart failure and significant mitral regurgitation. The CardioClip study endeavors to use another technology - a wireless pulmonary artery pressure sensor - that is implanted in a similar fashion to the way mTEER is performed (i.e., percutaneously, without surgery, through one of the veins in the groin), to see whether clinical outcomes can be improved further. The sensor continuously transmits information regarding heart function to clinicians who can optimize medications and their doses according to dynamic changes in pressure noted by the sensor.

The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item self-administered questionnaire developed to independently measure the patient's perception of their health status, which includes heart failure symptoms, impact on physical and social function, and how their heart failure impacts their quality of life (QOL) within a 2-week recall period. To facilitate interpretation, all scores are represented on a 0-to-100-point scale, where lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life (i.e., higher score indicates a better outcome). The Overall Summary (OS) score is the mean of four subdomain scores, each ranging from 0 to 100. A higher OS score indicates better outcome.
Time frame: 12 months
All-cause mortality rate will be calculated at 12 months.
Time frame: 12 months
Heart failure hospitalization (HFH) rate will be calculated.
Time frame: 12 months
An excellent clinical outcome is defined by a) survival, b) KCCQ-OS >60 points, and c) no decline ≥10 points in the KCCQ-OS relative to baseline at 12 months
Time frame: Baseline, 1 month, 6 months, 12 months post-mTEER
The KCCQ-OS evaluates health status from four principal domains: physical function, social function, symptoms, and quality of life. Participants receive a score for 0 to 100 in each domain, with higher scores indicating better health status in that specific domain. The score for each domain will be an individual secondary endpoint.

The different classes in the NYHA Classification of Heart Failure are:
Class I: No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation or shortness of breath.
Class II: Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, shortness of breath or chest pain.
Class III: Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, shortness of breath or chest pain.
Class IV: Symptoms of heart failure at rest. Any physical activity causes further discomfort.
