Abstract

Since its first description in 1971, the Fontan procedure and its modifications have led to a substantial improvement in the survival rates of patients with a variety of types of complex Congenital Heart Disease (CHD) characterised by the presence of a single, dominant ventricle. However, despite the significant improvement of the prognosis over the years, Fontan patients are still exposed to several cardiovascular and systemic complications. It is, therefore, important to fully understand the pitfalls hidden behind a Fontan anatomy and the potential predictors of ventricular failure. Cardiovascular imaging plays a key role in this context, allowing for the early identification of complications with important prognostic implications. Echocardiography remains the first-line imaging modality for serial evaluation of Fontan patients. However, there is a growing role of cardiovascular magnetic resonance and cardiac computed tomography from pre-operative assessment to longitudinal follow-up. The aim of this paper will be to provide a comprehensive overview of the role, strengths, and weaknesses of each imaging modality in the assessment of congenital cardiac conditions palliated with the Fontan procedure.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Phase-contrast flow CMR sequence measures blood flow velocities and can assess the severity of any obstructions or abnormalities in blood flow.

    “This sequence measures blood flow velocities and can assess the severity of any obstructions or abnormalities in blood flow.”

    From Multimodality imaging assessment of tetralogy of Fallot: From diagnosis to long-term follow-up (2023) · cites this paper as [33]

    The CMR Protocol (§3.1; page not provided) says phase-contrast imaging quantifies blood-flow velocities and can examine flow across sites for stenosis. The discussion of Fontan complications (§3.2; page not provided) adds that flow sequences can identify accelerations and estimate peak velocity. These passages support evaluating particular obstructions and flow abnormalities, but do not establish that the sequence assesses the severity of any such abnormality. (LLM, conf=0.82)

  • Cine CMR images allow for evaluation of wall thickness and regional and global systolic function, as well as calculation of LV and RV end-diastolic and end-systolic volumes and ejection fraction.

    “These images allow for the evaluation of wall thickness and regional and global systolic function, as well as the calculation of the LV and RV end-diastolic and end-systolic volumes and the ejection fraction.”

    From Multimodality imaging assessment of tetralogy of Fallot: From diagnosis to long-term follow-up (2023) · cites this paper as [33]

    Section 3.2 (page unavailable) says bSSFP cine images assess regional wall-motion abnormalities and systolic impairment and calculate end-diastolic and end-systolic volumes. Section 3.1 says cine slices are used to calculate ventricular volumes and ejection fractions. The paper does not specifically attribute wall-thickness evaluation to cine images, and its findings concern Fontan patients’ dominant and sometimes rudimentary ventricles rather than routine measurement of both the LV and RV. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • RV myocardial work indices have shown an important correlation with invasive indices of RV systolic function and prognostic value, especially in patients with pulmonary hypertension.

    “Although RV MW indices have shown an important correlation with invasive indices of RV systolic function and prognostic value, especially in patients with pulmonary hypertension [28,33], their role in TOF still needs to be investigated.”

    From Multimodality imaging assessment of tetralogy of Fallot: From diagnosis to long-term follow-up (2023) · cites this paper as [33]

    The Introduction and §2.2, Single Ventricle Function, discuss ventricular performance and prognostic measures in Fontan patients, but not right-ventricular myocardial work indices. Searches for myocardial work and for correlations with invasive RV systolic measures in pulmonary hypertension found no passage addressing the attributed claim. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
