Diagnosing and grading heart failure with tomographic perfusion lung scintigraphy: validation with right heart catheterization.

ABSTRACT:

Aims

Pulmonary congestion remains a diagnostic challenge in patients with heart failure (HF). The recommended method, chest X-ray (CXR), lacks in accuracy, whereas quantitative tomographic lung scintigraphy [ventilation/perfusion single-photon emission computed tomography (V/P SPECT)] has shown promising results but needs independent validation. The aim of this study is to evaluate V/P SPECT as a non-invasive method to assess and quantify pulmonary congestion in HF patients, using right heart catheterization as reference method. The secondary objective was to investigate the performance of V/P SPECT in the clinical setting compared with CXR.

Methods and results

Forty-six consecutive patients with HF that were under consideration for heart transplantation were studied prospec
