Factors for Mitral Regurgitation Recurrence 14 Days After Rheumatic Valve Repair

164 patient records from a study at Shanghai Fourth People's Hospital, Tongji University School of Medicine, between March 2023 and December 2025. The dataset contains factors associated with the development of mild or greater mitral regurgitation within 14 days after surgical repair. It was authored by RenDong Liang and last updated on April 28, 2026.

Use Cases

• Predict postoperative mitral regurgitation recurrence based on preoperative echocardiographic parameters like color jet area.
• Analyze correlations between preoperative mitral valve orifice area and other clinical factors.
• Assess the impact of intraoperative procedures, such as concurrent stripping of thickened leaflets, on short-term surgical outcomes.
• Perform logistic regression analysis to identify significant risk factors for early postoperative complications.

Strengths

• Dataset includes 164 patient records with a mean age of 44.73 years.
• Analysis is based on a specific 14-day postoperative time point for outcome measurement.
• Statistical methods like logistic regression and Pearson correlation are documented in the source description.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single hospital, which may limit generalizability.
