Venus P valve implantation was successful in 94% (61/65) of patients with RVOT dysfunction, with no deaths or re-interventions occurring during a median 13-month follow-up.

Does percutaneous implantation of the Venus P valve improve functional class and demonstrate safety in patients with RVOT dysfunction?
Real-world registry data demonstrates that percutaneous implantation of the self-expanding Venus P valve is feasible and safe for RVOT dysfunction, yielding significant functional improvement, though HALT and endocarditis warrant further monitoring.
Background: Self-expandable valves may have a significant impact on the feasibility of transcatheter treatments of RVOT dysfunction. Venus P valve is the first autoexpadable Valve that received CE mark in 2022. Here, we are reporting on a multicenter data collection about patients undergoing Venus P valve implantation in Italy. Materials: Seven italian centers were included in the study. Data were collected from patients treated with a venus P valve between July 2022 and May 2024. Indication for percutaneous valve implantation were in accordance with published guidelines. Results: During the study period, a total of 65 patients were considered eligible to percutaneous implantation of a Venus P valve. Median age at procedure was 35 years (IQR 12-63 years) median weight 63 Kg (IQR 33-103 Kg). Indication for PPVI was severe regurgitation in all subjects but one where ventricular pressure was increased because of stenosis on a homograft conduit and pulmonary arteries which needed previous bilateral stenting. Venus P valve was implanted successfully in 61/65(94 %) patients. Four procedural complications occurred(6 %): 1 artero-venous fistula, 1 pulmonary bleeding, 1 hemothorax and a pulmonary oedema. During follow up (median 13 months,1-20months), all patients experienced a significant improvement of functional class. Neither deaths or re-intervention occurred. CT Scan showed hypoattenuating leaflet thickness (HALT) in 4 patients and one of them experienced endocarditis 12 months after the procedure. Conclusions: Our study shows that Venus P valve implantation is safe and results are stable during a short-to-medium term follow-up. Endocarditis and HALT are inducing some concern and larger studies are needed.
Pilati et al. (Wed,) conducted a observational in RVOT dysfunction (n=65). Venus P valve implantation was evaluated on Successful implantation. Venus P valve implantation was successful in 94% (61/65) of patients with RVOT dysfunction, with no deaths or re-interventions occurring during a median 13-month follow-up.
