Preoperative Biomarkers and Outcomes for 492 Aortic Valve Surgery Patients

Between March 2018 and May 2022, a registry of 492 patients undergoing surgical aortic valve replacement or repair was compiled. The dataset, authored by Till Joscha Demal and shared under a CC-BY-4.0 license, includes preoperative blood biomarker levels and their association with 30-day postoperative mortality and morbidity. It was last updated on June 2, 2026.

Use Cases

• Training predictive models for postoperative mortality based on preoperative biomarker levels like hemoglobin and creatinine.
• Comparing the predictive performance of biomarker-enhanced models against established risk scores like EuroSCORE-II.
• Identifying key clinical indicators for adverse outcomes mentioned in the study, such as high-sensitivity troponin I and CRP.

Strengths

• Includes data from 492 patients, providing a specific cohort size for analysis.
• Contains 9 specific preoperative biomarkers (e.g., hemoglobin, hsTrop-I, NT-proBNP) with their statistical association to outcomes.
• Outcomes are adjudicated according to the VARC-III standard, suggesting a defined clinical endpoint.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small at 44.7 KB, indicating limited scope and likely a summary or document rather than raw patient-level data.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
