The AFteR Registry - Follow-up Study to Monitor the Efficacy and Safety of the Occlutech AFR in Heart Failure Patients

Официальное название

A Multicentre, International, Follow-up Study to Monitor the Efficacy and Safety of the Occlutech Atrial Flow Regulator in Heart Failure Patients

Обзор

This study aims to monitor the safety and efficacy of Occlutech AFR device in patients with Heart Failure.

Подробное описание

This is a prospective, multicentre, international, follow-up registry to monitor the safety and the performance of the Occlutech AFR device in patients with Heart Failure, to identify unknown side effects and to assess the indications and contraindications for an AFR treatment. Efficacy and safety of implanted device(s) will be evaluated by vital signs, laboratory test, quality of life questionnaire, ECG, and echocardiography data over a follow-up period of 36 month after implantation.

Patients will be treated according to the instruction-for-use of the device and according to clinical routine. Procedures will be performed at sites having appropriate laboratory support and adequately trained imaging personnel. Procedures will be performed by physicians with experience in a wide range of interventional cardiology and structural heart disease.

Критерии исключения

• Life expectancy < 1 year, or advanced heart failure defined as ACC/AHA Stage D heart failure, or listed for heart transplantation at time of baseline visit
• Evidence of right heart failure defined (by ECHO) as:

• Severe Right Ventricular Dysfunction (TAPSE < 14 mm)

• Documented history of specific cardiomyopathy (obstructive hypertrophic, restrictive, infiltrative) or pericardial disease
• Congenital heart defect that interferes with placement of the device, at the discretion of the Investigator.
• Previous interventional or surgical atrial septal defect (ASD) or patent foramen ovale (PFO) closure interfering with the placement of the device
• Current atrial septal defect, or anatomical anomaly (including > 10 mm atrial septal thickness or atrial septal aneurysm) on ECHO that precludes implantation of the device across the fossa ovalis (FO) of the interatrial septum

• Participating in another investigational clinical trial that could interfere with this study, at the discretion of the investigator
• Other clinically significant co-morbidities that make the patient unsuitable for study participation, at the discretion of the investigator

Note: \* LA pressure is substituted by PCW at the right heart catheterization measure while patient is awaken

\*\*"Corrected" refers to a 4% reduction in the NT-proBNP cutoff for every increase of 1kg/m2 in body mass index (BMI) above a reference BMI of 20kg/m2)
