  • Synergism between infarct-borne left ventricular dysfunction and Cardiomegaly in increasing the risk of coronary bypass surgery.
    The Journal of thoracic and cardiovascular surgery, 1992
    Co-Authors: Daniel A. Goor, Michael Golan, Yaron Bar-el, Rephael Mohr, Michaela Modan, Ayala Lusky, Judith Rozenman
    Abstract:

    The effect of Cardiomegaly on operative and late mortality in patients with left ventricular dysfunction undergoing coronary bypass operation was investigated. The study group consisted of 178 patients whose left ventricular ejection fraction was below 45% and who were operated on from 1978 through 1985. Forty-five patients (group A) had severe left ventricular dysfunction (ejection fraction ejection fraction > 45%). Twenty-four of group A (53%) and 54 of group B (41%) patients had Cardiomegaly (cardiothoracic ratio on chest x-ray films >0.5). There were 10 (6%) hospital deaths, four in group A (9%) and six in group B (4.5%). All four deaths in group A and the six deaths in group B were patients who had Cardiomegaly. Regardless of the severity of the left ventricular dysfunction, there was no operative death among patients with normal heart size (p horac C ardiovasc S urg 1992;104:983-9)

  • Cardiomyopathy and Cardiomegaly in Stillborn Infants of Diabetic Mothers
    Pediatric and developmental pathology : the official journal of the Society for Pediatric Pathology and the Paediatric Pathology Society, 2008
    Co-Authors: Noirin Russell, Stephen Quinn, Peter Kelehan, Michael Foley, Peter Holloway, Fionnuala M. Mcauliffe
    Abstract:

    To report the incidence of Cardiomegaly in stillborn normally formed infants of mothers with diabetes mellitus. This is a retrospective study with institutional ethics approval. The presence of Cardiomegaly was recorded in stillborn infants of diabetic mothers (N = 27) and compared with that recorded in stillborn large-for-gestational age (LGA > 90th percentile, n = 18) and stillborn appropriately grown (10th to 90th percentiles, n = 107) nondiabetic infants. Blinded to the clinical details, the histology slides were reviewed to measure cardiac wall thickness and to record the presence or absence of myocardial fiber disarray. Stillborn infants of mothers with diabetes mellitus, when compared with appropriately grown stillborn nondiabetic infants and when adjusted for birth weight, had heavier hearts, thicker ventricular free wall measurements, and lighter brains. While Cardiomegaly was reported in 22% of stillborn LGA infants, comparison with stillborn appropriately grown infants revealed no difference in heart weights corrected for birth weight. Comparison of LGA nondiabetic infants with stillborn diabetes mellitus infants revealed greater actual heart weight/expected for birth weight (P < 0.05) and lighter brains (actual brain weight/expected for birth weight, P < 0.05) in the diabetes mellitus group. Cardiomegaly is a common finding in stillborn infants of mothers with diabetes mellitus and may contribute to the risk of fetal death in these pregnancies.

  • Incidence of Cardiomegaly in stillborn infants of diabetic mothers
    American Journal of Obstetrics and Gynecology, 2005

    Abstract:

    NOREEN RUSSELL, PETER HOLLWAY, STEPHEN QUINN, PETER KELEHAN, MICHAEL FOLEY, FIONNUALA MCAULIFFE, NationalMaternityHospital,Dublin, Ireland, University College Dublin, Obstetrics and Gynaecology, Dublin, Ireland OBJECTIVE: The role of Cardiomegaly in the risk of sudden unexplained death in-utero is unclear. The study hypothesis is that Cardiomegaly in the fetus contributes to the risk of sudden death in –utero. The aim of the study is to report the incidence of Cardiomegaly in stillborn normally formed infants of diabetic mothers and to compare this with the incidence of Cardiomegaly in stillborn normally formed macrosomic infants (O90th centile) and stillborn normally formed appropriately grown infants (10-90th centile) without abruption and for whom no cause of stillbirth was identified. STUDY DESIGN: This is a retrospective study of hospital annual reports from 1985 to 2002 with institutional ethics approval. Cardiomegaly was defined as greater than 2 standard deviations above the mean weight for that gestational age (Wigglesworth et al). Additionally blinded to the clinical details, the pathologists (PH and PK) reviewed the histology slides to record the presence or absence of myocardial fibre disarray, a known feature of cardiomyopathy in adults. RESULTS: Over this 17 year period there were 28 stillborn infants in mothers with either insulin dependant diabetes or gestational diabetes, 26 of these had post-mortem examination. Of these 26, 7 had evidence of Cardiomegaly (27%). There were 19 stillborn infants that were macrosomic without maternal diabetes and 5 of these had Cardiomegaly on post-mortem (26%). None of the stillborn infants that were appropriately grown had evidence of Cardiomegaly (0/103). Stillborn macrosomic and stillborn infants of diabetic mothers were more likely to show Cardiomegaly on post-mortem (p!0.01). Myocardial disarray was evident in only 1 case of diabetic Cardiomegaly, suggesting that this histological parameter is not a feature of diabetic cardiomyopathy. CONCLUSION: Cardiomegaly may contribute to the risk of fetal death in macrosomic infants and infants of diabetic mothers. Myocardial disarray does not appear to be a constant histological characteristic of diabetic related fetal Cardiomegaly.

  • PERICARDIAL FAT SIMULATING Cardiomegaly.
    American Heart Journal, 2004
    Co-Authors: A.everett James, Daniel J. Torrance
    Abstract:

    Abstract A case of pericardial fat that gave rise to an enlarged cardiac silhouette simulating Cardiomegaly is presented. The virtual encasement of the heart by the large accumulation of pericardial fat led to difficulty in the differential diagnosis. The Cardiomegaly was shown by tomography to be due to fat.
