Previous studies have suggested that South Asian (SA) ethnicity is a predictor of poorer outcome after coronary artery bypass grafting (CABG). Our aim was to identify potential reasons for the higher postoperative mortality in SA patients and investigate all these reasons. All individuals undergoing isolated CABG in a tertiary cardiac centre from April 2002 to September 2007. In total, there were 2897 subjects (2623 white subjects; 274 SA subjects) who were included in an observational study showing the effect of ethnicity on the medium-term survival following CABG. Survival at 30 days and survival up to five years (median 2.7 years) were measured. SA subjects undergoing CABG were younger (62+/-9 vs. 66+/-9 years, P<0.001), less obese [body mass index (BMI) 26+/-4 vs. 28+/-4 kg/m(2), P<0.001] and had a higher prevalence of diabetes mellitus (58% vs. 33%, P<0.001) compared with white subjects. Thirty-day mortality was higher in SA subjects (2.6% vs. 1.0%, P=0.02). Non-diabetic SA had similar 30-day mortality, five-year survival and life expectancy compared to non-diabetic white subjects. In contrast, diabetic SA had a higher 30-day mortality (3.8% vs. 1.4%, P=0.01) and worse life expectancy compared to diabetic white subjects. The higher early postoperative mortality observed in SA patients is related to higher incidence of diabetes among them. SA diabetics have a significantly higher postoperative mortality and worse overall life expectancy. Ethnicity per se is not an independent predictor of short- or medium-term survival after CABG.
We report the case of an intrapericardial teratoma, a rare tumour in infants, prenatally diagnosed and successfully treated thanks to a multidisciplinary approach. An intrapericardial cystic mass (2.5 cm) with pericardial effusion was identified in a foetus at 32 weeks gestational age (GA). Intrauterine pericardiocentesis was performed immediately (40 ml) and repeated at 33 weeks (25 ml) and then at 34 weeks GA, just before birth (36 ml). Considering the rapid growth of the mass and the risk of hydrops, vaginal delivery was induced. A baby girl weighing 1.98 kg was born without cardiorespiratory compromise. Echocardiography and thoracic CT-scan located the 4.0×3.0 cm cystic mass between the left atrial appendage and the left superior pulmonary vein. At three days of life, the mass was completely removed without cardiobypass. It arose from the ascending aorta. Postoperative course was uneventful. Pathology diagnosed an immature intrapericardial teratoma. As long-term follow-up is required, alpha-fetoprotein can be a valid tool to monitor a possible recurrence. A multidisciplinary approach allows successful prenatal management and postnatal tumour surgery.
A joint programme between a small-volume centre and a large-volume centre may represent a valid and reproducible model for safe paediatric cardiac surgery in the context of a peripheral region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
