Investigation of a Transcatheter Tricuspid Valved Stent Graft in Patients With Carcinoid Heart Disease

Single Centre, Prospective, Single Arm Open Label Series of a Transcatheter Tricuspid Valved Stent Graft System for the Reduction of Tricuspid Regurgitation and Improved Patient Reported Outcomes in Patients With Carcinoid Heart Disease

Summary

The purpose of this investigation is to see if the TRICENTO Valved Stent Graft implant reduces tricuspid regurgitation (TR) and improves the symptoms and quality of life in 15 participants with carcinoid heart disease, and who are not able to have a new valve via a surgical procedure.

Detailed description

After being informed about the study and the potential risks and benefits, participants who provide written consent will be screened to make sure they fulfil the study entry requirements. This will involve a detailed medical history, a CT and an echo scan. Once it is agreed that the participant is suitable for the study, a custom-made TRICENTO valve is prescribed and made. Participants need to be admitted to hospital for the TRICENTO device to be implanted. Before the device is implanted the participant will have further tests and measurements completed eg ECG, a Cardiac MRI, physical measurements such as height, weight and blood pressure, blood tests, questionnaires and measuring how far they can walk in 6 minutes. The device is implanted in a cath lab procedure which should take about 30-60 minutes in total. Participants should be discharged from hospital about 2-3 days later after recovery and further echocardiogram, blood tests and questionnaires. Follow up visits are at 1 month and 6 months after the procedure. The following measurements such as an ECG, echocardiogram, and physical measurements (height, weight and blood pressure), some blood tests, questionnaires and measuring how far they can walk in 6 minutes will be repeated at 1 month and at 6 months after the procedure. A cardiac MRI will also be repeated at 6 months after the procedure. All these tests are to measure whether the TRICENTO valve improves the participant's heart function, symptoms and quality of life.

Conditions

• Tricuspid Regurgitation
• Tricuspid Valve Disease

• Carcinoid Heart Disease

Interventions

Type	Name	Description
DEVICE	Transcatheter Tricuspid Valved Stent Graft	All participants meeting the inclusion and none of the exclusion criteria will be enrolled. A custom-made Transcatheter Tricuspid Valved Stent Graft based on CT to define anatomic dimensions will be made. The system consists of a custom-made valved stent graft delivery system, a custom-made valved stent graft bioprosthesis and a loading system. The bioprosthesis is self-expanding and consists of a stent graft spanning from the inferior vena cava to the superior vena cava and a lateral bicuspid valve element made of thin porcine pericardial leaflets requiring a low closing pressure, and Nitinol support structures. The participants will undergo a minimally invasive, catheter-based procedure to implant the bioprosthesis which is delivered through a 24 French delivery system via transfemoral access. The device can be repositioned and is retrievable.
