We would like to enthusiastically invite you to attend the 9th International Congress on Cardiac Problems in Pregnancy (CPP 2025). The meeting will take place at the Intercontinental Hotel in Vienna, Austria, from April 24-27, 2025. This event will provide an opportunity for the international cardio-obstetric community to come together again for in-person interactions with colleagues and friends. Continuing the tradition of the previous eight meetings, the goals of CPP 2025 are to advance the knowledge and expertise of healthcare professionals worldwide in managing cardiovascular (CV) diseases during pregnancy. This will be achieved through the exchange of information and updates on recent data. The meeting will include numerous plenary sessions featuring state-of-the-art reviews by renowned experts. It will incorporate the results of contemporary research as well as clinical observations and case presentations, followed by expert discussions.
