ABSTRAK
TujuanPenelitian mengenai penggunaan analisis faktor risiko dan mortalitas pada operasijantung masih menjadi perdebatan dan merupakan area yang sedang berkembang.Analisis faktor risiko dalam penilaian suatu hasil pembedahan jantung merupakan halyang tidak dapat dihindari. Ahli bedah dan rumah sakit memerlukan suatu hasilpenilaian faktor risiko terhadap risiko kejadian mortalitas perioperasi agar dapatmenentukan keputusan klinis. Tujuan penelitian ini adalah untuk membandingkanParsonnet dan European System for Cardiac Operative Risk Evaluation (EuroSCORE)pada pasien yang menjalani perbaikan katup mitral dan memperkirakan faktor-faktorrisiko apa saja yang dapat mempengaruhi mortalitas perioperatif.Pasien dan MetodeDari bulan Januari 2010 sampai dengan bulan Desember 2012, 96 pasien terpilih yangtelah menjalani operasi perbaikan katup mitral menggunakan mesin jantung paru dantelah dilakukan analisis faktor risiko berdasarkan Parsonnet score and EuroSCORE .seluruh faktor risiko dianalisis dengan analisis deskriptif, tabulasi silang, Pearson ChiSquare, dan uji Anova, keduanya juga dianalisis dengan kurva ROCHasilAngka mortalitas riil sebesar 5,2 %. Berdasarkan Parsonnet score, nilai prediksimortalitas sebesar 18,26 % sementara pada EuroSCORE nilai prediksi mortalitassebesar 3,68 %. Hasil keduanya signifikan secara statistik. Nilai prediksi EuroSCORElebih mendekati angka kematian riil bila dibandingkan Parsonnet score .KesimpulanEuroSCORE lebih unggul dibandingkan dengan Parsonnet score .Nilai prediksiEuroSCORE lebih mendekati angka kematian riil . EuroSCORE merupakan alat ukuryang baik dalam analisis faktor risiko dan mortalitas pada operasi perbaikan katupmitral

ABSTRACT
ObjectiveThe use of risk stratified mortality studies for analyzing surgical outcome in cardiacsurgery is obviously a developing area. Unfortunately, outcomes research in valverepair surgery has been relatively limited. The risk stratification in the assessment ofcardiac surgical results is inevitable. Surgeons and hospitals need availability of riskassessment result which may influence decision-making. Without risk stratification,surgeons and hospitals treating high-risk patients will appear to have worse resultsthan others. Our purpose was to compare the performance of risk stratification models,Parsonnet and European System for Cardiac Operative Risk Evaluation (EuroSCORE)in our patients undergoing mitral valve repair (MVr) and predict the risk factors thatinfluence inhospital mortality .Patient and methodsFrom January 2010 to December 2012, 96 consecutive patients have undergone MVrusing cardiopulmonary bypass and scored according to Parsonnet score andEuroSCORE algorithm. All risk factors were analyzed by descriptive analytic, crosstabulation, Pearson Chi Square, and Anova test, both scores analyzed by ROC curve.ResultsOverall hospital mortality was 5,2 %. In Parsonnet model, predicted mortality was18,26 % while in the EuroSCORE model, predicted mortality was 3,68 %. and it wasstatistically significant for the Parsonnet score and EURO score . Parsonnet Score hasa higher sensitivity compared to the EuroSCORE. From the ROC curve, AUC forParsonnet score (0,905) higher than AUC for EuroSCORE (0,892). Problems with theParsonnet score of subjectivity, inclusion of many items not associated with mortality,and the overprediction of mortality have been highlighted. Pre operative NYHA class,age, ejection fraction , complication, etiology, EuroSCORE, and Parsonnet scoreduring mitral valve repair were statistically significant for affecting inhospitalmortality risk.ConclusionsThe EuroSCORE is more reasonable overall predictor of hospital mortality in ourpatients undergoing MVr compared to Parsonnet score.
