    Dear Editor,

    We thank Drs Mclaren et al. for their interest in our study.

    Firstly, we chose Vancomycin as we wished to use an antistaphylococcal drug that had been studied in cardiac surgical patients. Additional rifampicin was used in an attempt to prevent resistance developing. Clearly the strategy was successful as we did not see any increase in resistant organisms during, or for the 2 years after,...

    Dear Editor,

    We thank Dr. Ballo and colleagues for their interesting comments on our article. In agreement with our study, Ballo et al show a nonlinear association between circumferential midwall and longitudinal LV systolic function in patients with hypertension [1]. It is particularly noteworthy that this nonlinear association is apparent in two different study populations. The patients in our study were suff...

  • Antibiotic prophylaxis in cardiac surgery
    Graeme MacLaren

    Dear Editor,

    The recent study by Dhadwal et al. (1) has a number of weaknesses which merit discussion. The study appears to have been initiated by a “perceived increase in crude infection rates” but the organisms responsible for this increase were not presented. Unless there was a high incidence of infection with resistant organisms such as methicillin- resistant Staphylococcus aureus (MRSA) prior to study comme...

  • Prognostic value of left ventricular long-axis versus short-axis systolic function in heart failure
    Piercarlo Ballo

    Dear Editor,

    Grüner Sveälv et al.(1) recently found that left ventricular (LV) long-axis atrioventricular plane displacement (AVPD) in heart failure (HF) patients was linearly correlated with short-axis fractional shortening (LVFS) in the lower range of AVPD, but not in the higher range of AVPD. They also observed that decreasing AVPD quartiles showed a stepwise association with worsening prognosis. Notably, a sim...

  • Low EF: the best marker of poor prognosis in patients affected by non compaction
    Giovanni Fazio
    Dear Editor,

    McMahon et al reported in a recent article a reduction of TD velocities in children with noncompaction of the left ventricle, compared with normal controls. The authors concluded their work saying that the reduction of lateral mitral Ea velocity helps to predict children with LVNC who are at risk of adverse clinical outcomes including death and need for cardiac transplantation. In a precedent report our group re...

  • Instead of compression by haematoma, occlusion by a thrombus can be the complicating factor
    Oscar M Jolobe

    Dear Editor,

    In the context of involvement of the right pulmonary artery by aortic dissection, instead of being caused by extrinsic compression attributable to a haematoma(1)(2)(3), obstruction of the right pulmonary artery might be attributable to thrombosis, with associated extrinsic compression by a massively dilated aorta, as shown in the instance of a 69 year old man who initially presented with stigmata of...

  • Is this the first case ?
    Manokar Panchanatham

    Dear Editor,

    I would like to draw your attention to the statement"As far as we know, this is the first reported case of all three coronaries originating from a single ostium from the aorta." in the above article.

    There are mulitiple papers on single coronary artery, there are classifications for single coronary artery (e.g Smiths'), people have done treadmill testing in patients with single coronary ar...

  • Cardiovascular mortality in the Glasgow Cohort: from the Great War to the United Nations
    Francesco Corea

    Dear Editor,

    Yu-Kang Tu brilliant work investigated the complex emerging field of microbial risk factors and cardiovascular disease. The paper concluded that tooth loss (used as an index for poor oral health) is related to CVD mortality. However, a clear link between both conditions is missing in the study. This publication raised in our group many reflections. The related editorial published in the same issue of...

  • Impact of blood pressure change and hypertension on aortic stenosis
    Katerina Linhartova

    Dear Editor,

    I read with great interest the study by Little et al. (1) investigating the effect of acute blood pressure change on hemodynamic parameters of aortic stenosis (AS). Their implication that "differences in haemodynamics should be considered as a potential explanation for a change in AS severity independent of disease progression" should be stressed not only in clinical practice, but as well in prospect...

  • QRS and prognosis in heart failure.
    Francesco Grigioni

    Dear Editor,

    Breidthardt et al. (1) found that acute decompensated heart failure (HF) patients presenting to their Emergency Department with prolonged QRS interval (>=120 ms) showed higher long-term mortality. This is a pathophysiologically plausible finding: after initially representing a marker of diseased myocardium, prolonged QRS may itself subsequently contribute to disease progression. (2) Nevertheless,...
