Zusammenfassung der Studie

When patients with severe aortic valve stenosis also present with significant coronary artery stenosis, both conditions must be treated. For patients for whom the indication for catheter-based treatment is made (in the so-called "heart team", which is interdisciplinary and composed of specialists from different fields), it is still unclear in which order the procedures should be performed to achieve the best outcome. In some patients, the percutaneous coronary intervention (PCI) is performed prior to the heart valve implantation, while in others, such an intervention is postponed to later, i.e., after the heart valve procedure. Currently, there are no scientific data to confidently make the right decision regarding the order of the interventions. The TAVI PCI study therefore addresses this question and investigates the timing of the two treatments. A total of 986 patients will be included in the study across 5 countries, and it will be decided randomly (randomization) whether the treatment of the narrowed coronary arteries or the treatment of the narrowed aortic valve will be performed first. For patients assigned to group 1, the treatment of the coronary arteries (PCI) will be performed first, followed by the treatment of the aortic valve (TAVI) within a period of 1-45 days. For patients assigned to group 2, the treatment of the aortic valve (TAVI) will be performed first, followed by the treatment of the coronary arteries (PCI) within a period of 1-45 days. The study only investigates the order of treatments. The treatment itself is performed according to current guidelines and does not differ in execution from patients who do not participate in the study.

Untersuchte Intervention

The study does not investigate the treatments themselves, but the order of the treatments of coronary intervention (PCI) and catheter aortic valve replacement (TAVI) in patients with aortic valve stenosis and coronary artery stenoses, for whom both interventions are indicated. The treatments themselves are performed according to current guidelines and do not differ in execution from those of patients who do not participate in the study. The study compares the treatment sequence "PCI before TAVI" (group 1) with the treatment sequence "PCI after TAVI" (group 2). For patients assigned to group 1, the treatment of the coronary arteries (PCI) will be performed first, followed by the treatment of the aortic valve (TAVI) within a period of 1-45 days. For patients assigned to group 2, the treatment of the aortic valve (TAVI) will be performed first, followed by the treatment of the coronary arteries (PCI) within a period of 1-45 days.

The aortic valve connects the heart to the circulation and functions as a valve. With increasing age, calcification and narrowing of the aortic valve, known as aortic stenosis, can occur, and blood flow into the systemic circulation is impeded. This condition is one of the most common heart valve diseases. The condition leads to symptoms such as chest pain, shortness of breath, or dizziness and loss of consciousness. Once symptoms occur, this condition has a poor prognosis if left untreated. A severe narrowing of the aortic valve is therefore treated by inserting a new heart valve. This procedure can nowadays usually be performed via catheter through the groin vessels (transcatheter aortic valve implantation, TAVI). In patients with aortic valve stenosis, about half also present with narrowing of the vessels that supply blood to the heart, the coronary arteries. This involves inflammation and calcification of the vessel wall, leading to plaque formation and thus impeding blood flow. This condition must also be treated catheterically if it exhibits a certain degree of severity, using balloon dilation and the insertion of a small vascular support, known as a stent (percutaneous coronary intervention, PCI). The TAVI PCI study now investigates the optimal sequence of treatment for aortic valve stenosis and coronary artery stenoses and addresses the question of whether the heart valve or the coronary arteries should be treated first.
