About

This study aims to investigate safety and efficacy of Occlutech® AFR device in patients with severe pulmonary hypertension (PH).

Full description

This study will enroll subjects with severe pulmonary hypertension until a maximum of 30 patients have undergone implantation with the Occlutech® AFR device. Enrolment will be devided in 2 phases. Phase 1: At least 15 adult patients with age ≥ 18 years will be enrolled. Phase 2: Patients with age ≥ 6 years will be enrolled until a maximum of 30 patients is reached.

Inclusion criteria

  • Age is ≥ 18 / ≥6 years (phase 1 / phase 2).
  • Patient consents to participation
  • The patient or his/her legal representative should have the ability to fluently speak and under-stand the language in which the study is being conducted. If the patient speaks a different language, then a sentence-to-sentence translation for unequivocal understanding must be provided.
  • Written, informed consent by the patient or her/his legally-authorized representative for participation in the study.
  • Patient agrees to comply with the follow-up schedule.
  • Patient has had a successful BAS procedure and is in a stable hemodynamic state, as assessed by the investigator.
  • Conventional treatment options for the patient are exhausted according to ESC and AHA guidelines.
  • SpO2> 86 % pulsoxymetric measurement) This document is confidential and property of Occlutech. It´s only for clinical personnel, Ethical committees and third person in direct contact with the clinical responsible. It is not allowed to distribute information contained in this document without the permission of Occlutech unless the information is already published.
  • "Syncope"(Group A-PH) 9.1. Syncope due to acute PH episodes (as defined by exclusion of other causes) 9.2. Other causes of syncope must have been actively excluded 9.3. Syncope (Black-out) or pre-syncope (episodic dizziness) >2 last 3 months 9.4. PH (defined as mean pulmonary artery pressure > 25 mmHg, or pulmonary vascular resistance of > 3 Wood Units) must exist, RV-failure is however not a prerequisite
  • "RV-Failure"(Group B-PH) 10.1. Right heart failure, chronic and clinically severe 10.1.1.NYHA class III or worse 10.1.2. 6 min walk < 320 m 10.1.3. Signs of venous congestion (distended veins, edema, ascites, etc) 10.1.4.Symptomatic disease resulting in 1 or more PH-related hospitalization over the last 12 months. Elective hospital admissions solely for the purpose of performing diagnostic procedures do not count for this.

10.2. Severe pulmonary hypertension as evident by echocardiography Echocardiographic: 10.2.1. RV larger than LV; 10.2.2. RA larger than LA; 10.2.3. atrial septum bulging into left atrium 10.2.4.ventricular septum bulging into the left ventricle 10.2.5.Reduced (below age-related normal mean value) TAPSE 10.3. Severe pulmonary hypertension as evident by CATH CATH-data: 10.3.1.Mean RA pressure (RAP) of > 10 and ≤ 20 mmHg; 10.3.2.Mean LA pressure (LAP) < 15 mmHg 10.3.3.Mean RAP > mean LAP; 10.3.4.Mean pulmonary arterial pressure >25 mm Hg 10.3.5. Echocardiographically demonstrated continuous right to left shunt following balloon aterial septostomy (BAS) and before AFR device implantation.

Exclusion Criteria

Processes which interfere medically with invasive device implantation

  • Local or generalized sepsis or other acute infection(s)
  • Thrombophilic coagulation disorder
  • Allergy to nickel and/or titanium and/or nickel/titanium-based materials
  • Allergy to anti-platelet, -coagulant, or -thrombotic therapy
  • Intolerance to contrast agents
  • Participation in other medical trials shorter than 30 days before the intended AFR implantation procedure
  • Pregnancy - (assessed in patients with child bearing potential by urine dip stick)
  • Any intracardiac intervention within the last 30 days
  • Thickness of atrial septum > 12mm OR Processes which would technically disturb the safe intervention as planned

1. Occluded inferior vena cava access 2. Previous ASD/PFO closure device in place 3. Intracardiac thrombus OR any other circumstance that, in the opinion of the Investigator,

might interfere with the implantation, might affect the patient's well-being thereafter or might interfere with the conduct and follow up within the Study is general.
