  • Diagnosis of patent foramen ovale
    Herwig W Schuchlenz

    Dear Editor

    We have read with great interest the recent editorial by C Seiler about how patent foramen ovale (PFO) should be assessed [1]. While contrast transesophageal echocardiography (cTOE) and transcranial Doppler ultrasound have facilitated clinical recognition of right to left shunts, the optimum approach to diagnosis of PFO requires further clarification. The editorial emphasizes the importance of a corr...

  • BSC's cardiac troponin cutoff concentrations for myocardial infarction: “Back to the Future"
    Alan H. Wu

    Dear Editor,

    We read with great interest the British Cardiac Society’s (BCS) recommendations regarding proposed nomenclature for acute coronary syndromes (ACS) [1]. These experts attempt to alter the new definition of myocardial infarction (MI) established by the European Society of Cardiology (ESC) /American College of Cardiology (ACC) that rely predominately on increased concentrations of serum biomarkers of...

  • Magnetic resonance and cardiovascular implanted devices
    Ariel Roguin

    Dear Editor,

    Prasad SK et al [1], presented clearly the interaction between cardiovascular magnetic resonance (CMR) and cardiovascular implants and devices. The authors summarized the available data regarding patient screening before MRI, ECG leads, sternal and epicardial pacing wires, heart valve prostheses and annuloplasty rings, coronary stents, other vascular stents, and coils and filters, occlusion dev...

  • Prospective longitudinal assessment of late anthracycline cardiotoxicity after childhood cancer
    Frances A Bu'Lock

    Dear Editor,

    The authors are to be congratulated on providing a 5 year follow up report on their groups of Wilm’s tumour and acute lymphoblastic leukaemia (ALL) patients first studied in 1991-2.

    It is very interesting that their findings are very similar to our own follow-up cohort [1] and that these abnormalities are more noticeable than at a shorter post-treatment interval [2]. What is odd is that cle...

  • Amiodarone to support DC cardioversion for atrial fibrillation
    Kevin S. Channer

    Dear Editor,

    We applaud Boos et al for their study of short term amiodarone treatment to reduce relapse rate after DC cardioversion for chronic atrial fibrillation. The results of this small randomised trial were similar to our placebo controlled trial[1]. However, we also found that oral loading with amiodarone 2 weeks prior to planned cardioversion resulted in pharmacological cardioversion in 21% of patie...

  • Catheter induced concertina effect in the right iliac artery
    Vimal Mehta

    Dear Editor,

    We read with interest the image report by Ahn et al[1] However, we differ regarding the mechanism of the pseudolesions described. The right iliac artery is not having spasm as reported but the narrowings are because of concertina effect. Concertina or accordian effect is the appearance of artefactual or pseudolesions which appear in a tortuous vessel when it is straightened by a guidewire or...

  • Risk assessment with low numbers
    R A Johnson

    Dear Editor,

    In their article discussing the use of right ventricular pacing in balloon dilatation of the aortic valve Daehnert et al describe the procedure as "safe". Whether a process is safe or not doeas rather depend on your point of view. However the use of the term safe applied in the context a procedure used in 14 patients is clearly not justified. The underlying risk of mortality could be as high...

  • Might these patients do better without inotropes?
    Richard G Fiddian-Green

    Dear Editor,

    Looking at the problem from a metabolic perspective it would seem to me that the therapeutic objective in these patients might be to achieve the highest cardiac reserve at rest by increasing the nutrient energy density per unit volume of flowing blood. This should optimise their capacity for increasing ATP resynthesis by oxidative phosphorylation in response to a sudden increase in need for energy f...

  • Successful evolutionary adaptation to environmental stress?
    Richard G Fiddian-Green

    Dear Editor,

    This sociological study demonstrates associations between exposure to cold in utero and soon after birth, dyslipidaemia and coronary heart disease [1]. The inference that exposure to cold in utero or early in life in disadvantaged homes might increase the risk of coronary artery disease by causing a dyslipidaemia is not supported by all epidemiological studies. Certain indigenous populations, such as t...

  • Mirror image reasoning not always necessary in situs inversus
    Tammo Delhaas

    dear Editor,

    We read with interest this case report by Saha et al on a situs inversus patient with an acute coronary syndrome.

    They suggest that inferior ST-segment elevation may occur with occlusion of the left anterior descending artery. This we find difficult to believe and we offer a different explanation.

    Firstly, we strongly believe that ST-T elevation in II, III, and aVF reflects...
