Babu-Narayan SV, Uebing A, Davlouros PA, et al., 2012, Randomised trial of ramipril in repaired tetralogy of Fallot and pulmonary regurgitation: the APPROPRIATE study (Ace inhibitors for Potential PRevention Of the deleterious effects of Pulmonary Regurgitation In Adults with repaired TEtralogy of Fallot)., Int J Cardiol, Vol: 154, Pages: 299-305
Optimal treatment for stable repaired tetralogy of Fallot (rTOF) patients with pulmonary regurgitation (PR) and related right ventricular (RV) dilatation, including timing of valve implantation, remains uncertain. We sought to study tolerability of the angiotensin-converting-enzyme (ACE) inhibitor ramipril and its effects on cardiovascular function in these patients.

Johansson B, Babu-Narayan SV, Kilner PJ, et al., 2010, 3-dimensional time-resolved contrast-enhanced magnetic resonance angiography for evaluation late after the mustard operation for transposition., Cardiol Young, Vol: 20, Pages: 1-7
PURPOSE: Cardiovascular magnetic resonance assessment of adults late after an atrial redirection operation for transposition is demanding and time consuming. We hypothesised that the relatively fast and standardised 3-dimensional time-resolved contrast-enhanced magnetic resonance angiography, or dynamic angiography, would be valuable in the periodic follow-up of these patients. METHODS: We investigated prospectively 36 adults with transposition using dynamic angiography, comparing our results against a comprehensive but non-contrast cardiovascular magnetic resonance protocol. We acquired 6 dynamic angiographic datasets after injection of contrast. The primary aim was to detect significant obstruction of the pathways for venous flow. RESULTS: In 4 patients (11%), we found evidence of moderate-to-severe, and thus clinically important, obstruction of systemic venous channels on standard cardiovascular magnetic resonance. All these patients were correctly identified by dynamic angiography. In 4 additional patients, we found mild and haemodynamically insignificant obstructions in the systemic venous channels. Of the 8 (22%) patients with any obstruction, 6 were detected by angiography. There were no false positives reported, giving sensitivity of 75% and specificity of 100%, a positive predictive value of 100%, and negative predictive value of 93%. In 1 patient, there was a moderate obstruction of the pulmonary venous compartment which was not readily seen by dynamic angiography. CONCLUSIONS: 3-dimensional dynamic angiography is a useful method for detecting anatomically moderate-to-severe, but not mild, obstructions in the systemic venous channels following Mustard repair for transposition. This technique can be used as a single imaging method and/or as complimentary to standard two dimensional cardiovascular magnetic resonance techniques for detection of clinically important obstructions in the systemic venous channels.

Babu-Narayan SV, 2010, The role of late gadolinium enhancement cardiovascular magnetic resonance in the assessment of congenital and acquired heart disease, Progress in Pediatric Cardiology, Vol: 28, Pages: 11-19, ISSN: 1058-9813
Cardiovascular magnetic resonance imaging (CMR) has become a cornerstone in the diagnosis and management of congenital heart disease and selected paediatric cardiology patients. This article reviews the relevance of late gadolinium enhancement (LGE) CMR in both congenital and acquired heart diseases. Commonly, adult LGE CMR is with a view to understanding myocardial viability in older ischaemic heart disease patients, where the extent, location, pattern and transmurality of LGE relate to longer term outcomes. However, LGE findings also contribute to diagnosing non-ischaemic cardiomyopathies and their potential aetiology. New uses also include using LGE CMR as an outcome measure in the assessment of interventions including pharmacotherapies. With time there is emerging data regarding a potential role for LGE CMR in risk stratification for arrhythmia and sudden cardiac death. There is therefore understandable interest in its relevance from clinicians involved in assessing and caring for cardiovascular disease in the young, whether congenital or acquired and early reports in these settings are discussed. After outlining aspects concerning principle, practice and pitfalls of the technique, the described clinical experience of late gadolinium enhancement will be discussed. Robust research will be required to fully understand where LGE CMR will fit in with routine clinical paediatric cardiology and adult congenital practice but it seems likely to have a unique role to improve diagnosis and management strategies, determine response to therapies, and assess long term prognosis, not only in ischaemic heart disease patients, but in these cardiac patients too. © 2009 Elsevier Ireland Ltd.
