Collateral flow quantification by cardiovascular magnetic resonance during continuous submaximal exercise in patients with total cavo-pulmonary connection

چکیده
Results TCPC patients had significantly lower systemic blood flow(Qs) at rest (2.7±0.6 vs. 3.6±0.7 L/min/m2, p<0.001) and during exercise (3.4±1.0 vs. 4.9±0.9 L/min/m2, p<.0001), than healthy controls. The increase in Qs with exercise was also significantly lower in patients, than in healthy controls (0.6 vs. 1.2 L/min/m2, p<0.02). Absolute collateral flow did not change in TCPC patients during exercise compared to rest (0.4±0.3 vs. 0.5±0.4 L/ min/m2, p=0.97). Conclusions Clinically well doing patients with TCPC have significant collateral flow at rest (17% of Qs) that does not change during submaximal exercise (14% of Qs).

Systemic-to-pulmonary collateral flow, as measured by cardiac magnetic resonance imaging, is associated with acute post-Fontan clinical outcomes.
BACKGROUND Systemic-pulmonary collateral (SPC) flow occurs commonly in single ventricle patients after superior cavo-pulmonary connection, with unclear clinical significance. We sought to evaluate the association between SPC flow and acute post-Fontan clinical outcomes using a novel method of quantifying SPC flow by cardiac magnetic resonance (CMR) imaging. METHODS AND RESULTS All patients wh...
متن کاملQuantification of thoracic aorta blood flow by magnetic resonance imaging during supine cycling exercise of increasing intensity
Background Cardiac magnetic resonance imaging (MRI) may be used for the diagnosis and follow-up of diseases affecting the thoracic aorta (TA). Typically, patients are imaged at rest. Quantifying TA blood flow distribution during activity may improve understanding of disease impact by assessing possible factors contributing to exercise intolerance. Blood flow quantification during exercise MRI, ...
متن کاملFlow-sensitive four-dimensional magnetic resonance imaging facilitates the quantitative analysis of systemic-to-pulmonary collateral flow in patients with univentricular hearts
Background Systemic-to-pulmonary collateral flow (SPCF) may constitute a risk factor for increased morbidity and mortality in patients with single-ventricle physiology (SV). However, clinical research is limited by the complexity of multi-site two-dimensional (2D) cardiovascular magnetic resonance (CMR) flow assessment. We sought to validate four-dimensional flow (4D-flow) for concise quantific...

متن کاملReduced peripheral arterial blood flow with preserved cardiac output during submaximal bicycle exercise in elderly heart failure
BACKGROUND Older heart failure (HF) patients exhibit exercise intolerance during activities of daily living. We hypothesized that reduced lower extremity blood flow (LBF) due to reduced forward cardiac output would contribute to submaximal exercise intolerance in older HF patients. METHODS AND RESULTS Twelve HF patients both with preserved and reduced left ventricular ejection fraction (LVEF)...
