ESC-Leitlinien zu Herzklappenerkrankungen

Abstract

In 2012 the new and collaborative "Guidelines on the management of valvular heart disease (version 2012)" were published by the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS). These guidelines emphasize that decision-making in patients with valvular heart disease should ideally be carried out by a"heart team" with particular expertise in valvular heart disease. In aortic regurgitation pathologies of the aortic root are frequent and in patients with Marfan syndrome, surgery is indicated when the maximal ascending aortic diameter is ≥50 mm, while the threshold for intervention should be lower in patients with risk factors for progression. Regarding aortic stenosis, transcatheter aortic valve implantation (TAVI) should be performed only in hospitals with on-site cardiac surgery and with a"heart team" available to assess patient risks. The TAVI procedure is indicated in patients with severe symptomatic aortic stenosis who are judged by the"heart team" to be unsuitable for surgery but have sufficient life expectancy. It should be considered for high-risk patients with severe symptomatic aortic stenosis based on the individual risk profile assessed by the"heart team". Furthermore, low flow - low gradient aortic stenosis with normal ejection fraction and the difficult topic of asymptomatic severe aortic stenosis and the indications for aortic valve replacement are discussed. With respect to mitral regurgitation, valve repair should be the preferred technique when it is expected to be durable. The topics of asymptomatic mitral regurgitation as well as percutaneous mitral valve repair using the edge to edge technique as an alternative for high risk patients are discussed. Tricuspid disease should not be forgotten and during left-sided valve surgery, tricuspid valve surgery should be considered in the presence of mild to moderate secondary regurgitation if there is significant annular dilatation. Last but not least, in patients with aortic bioprostheses the use of low-dose aspirin is now favored for a 3-month postoperative period.

Percutaneous Transaortic Valve Replacement for Critical Aortic Stenosis: Single Center Experience

“…Transvalvular systolic gradient at an aortic valve level of >64 mmHg and average gradient of >40 mmHg at echocardiography is defined as critical AS. Aortic valve replacement is an indispensable treatment for patients with symptomatic (orthopnoea, angina pectoris, and syncope) AS [3,4] . Percutaneous transcatheter aortic valve replacement (TAVR) is a treatment that should be especially applied to older patients with AS and additional diseases at high risk during operation.…”
