In the present study, efficacy of minimally-invasive serum Raman spectroscopy (SRS) in stratification of congenital heart diseases was explored. Blood was collected from 62 subjects [42 congenital heart defect (CHD) patients (19 with atrial septal defect, 13 with ventricular septal defect and 10 with tetralogy of fallot) and 20 controls], and serum separated. Raman spectra of sera were recorded, pre-processed and subjected to spectral and multivariate analyses. Multivariate curve resolution-alternating least squares (MCR-ALS) analyses indicated alterations in lipid and protein levels between the study groups. Principal Component Analysis (PCA) and Principal Component based Linear Discriminant Analysis (PC-LDA), cross-validated with Leave-one-out cross validation (LOOCV), were employed to study stratification between the different groups. CHD could be classified from controls with 76 % efficiency. The different CHD subtypes could be distinguished with efficiencies as high as ∼90 %. To the best of our knowledge, differentiation between controls and CHDs as well as the stratification between controls and CHDs subtypes was for the first time successfully accomplished by serum-based Raman spectroscopy., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Cardiogenic shock remains associated with unacceptably high mortality, but recent improvements with early revascularization, continued support with pharmacologic agents, and use of an intra-aortic balloon pump have led to improvements in the rate of mortality. Timely intervention with cardiac surgery in patients with mechanical complications, 3-vessel disease, and left main disease is beneficial. Continued research and ever-improving understanding of this once deadly condition have helped further in improving prognosis. Cutting-edge technologies, such as myocyte cell implantation and the use of a cooling system, will help in pushing the boundaries farther., (Copyright © 2013 Elsevier Inc. All rights reserved.)
