“…5,6 Consequently, H2 relaxin shows diverse physiological functions, including anti-inflammatory, anti-fibrotic, and vasodilatory, and is currently undergoing clinical trials for the treatment of a variety of diseases in several countries. 7–13 Although a recent clinical trial (Novartis; second phase III) 14 found no significant effect of H2 relaxin on the treatment of acute heart failure, there is still a great deal of interest in H2 relaxin's pharmacological applications. Several research institutions, including pharmaceutical companies, have developed a variety of H2 relaxin-related formulation candidates, such as long-acting relaxins, 15,16 single-chain relaxin mimics, 17–19 and small molecular RXFP1 agonists, 20,21 some of which are undergoing clinical trials.…”

The pulmonary valve is the most frequently replaced cardiac valve in congenital heart diseases. Whether the valve alone or part of the right ventricular outflow tract have to be repaired or replaced depends on the specific pathological anatomy of the malformation. Once the decision to replace the pulmonary valve has been made, two options are available: the isolated transcatheter pulmonary valve replacement and the surgical implantation of a prosthetic valve either isolated or in combination with a procedure on the right ventricular outflow tract. In this paper, we will focus on the different past and present surgical options and present a new concept called “endogenous tissue restoration,” a promising alternative to the hitherto existing implants. From a general point of view, neither the transcatheter nor the surgical valvular implants are magic bullets in the arsenal for the management of valvular diseases. Smaller valves have to be frequently replaced because of outgrowth of the patients, larger tissue valves may present late structural valve deterioration, while xenograft and homograft conduits may calcify and therefore become narrowed within unpredictable incidence and interval following implantation. Based on long-term research efforts combining the knowledge of supramolecular chemistry, electrospinning, and regenerative medicine, endogenous tissue restoration has emerged most recently as a promising option to create long-term functioning implants. This technology is appealing because following resorption of the polymer scaffold and timely replacement through autologous tissue, no foreign material remain at all in the cardiovascular system. Proof-of-concept studies as well as small first-in-man series have been completed and have demonstrated favorable anatomic and hemodynamic results, comparable to currently available implants in the short term. Based on the initial experience, important modifications to improve the pulmonary valve function have been initiated.
