Imaging of Valvular Heart Disease in Heart Failure.

Valvular heart disease (VHD) and heart failure (HF) are major health issues that are steadily increasing in prevalence in Western populations. VHD and HF frequently co-exist, which can complicate the accurate diagnosis of the severity of valve stenosis or regurgitation and affect decisions about therapeutic options. Transthoracic echocardiography is the first-line imaging modality to determine left ventricular (LV) systolic function, to grade valvular stenosis or regurgitation and to characterise the mechanism underlying valvular dysfunction. 3D transoesophageal echocardiography, cardiovascular magnetic resonance and cardiac CT are alternative imaging modalities that help in the diagnosis of patients with HF and VHD. The integration of multimodality cardiovascular imaging is important when deciding whether the patient should receive transcatheter aortic valve repair and replacement therapies. In this article, the use of multimodality imaging to diagnose and treat patients with VHD and HF is reviewed.
