Percutaneous Transseptal Bioprosthetic Implantation in Failed Prosthetic Surgical Mitral V

Pedro Felipe Gomes Nicz and colleagues report on the first Brazilian multicenter experience with transseptal transcatheter mitral valve-in-valve implantation (transseptal-TMVIV). The dataset likely contains clinical and echocardiographic data for 17 patients from 12 Brazilian hospitals who underwent the procedure between June 2016 and February 2019. It includes pre- and post-intervention metrics such as mitral valve gradient, valve area, and pulmonary artery systolic pressure, with a median follow-up of 162 days.

Use Cases

• Analyze procedural success and complication rates based on patient cohort data.
• Model changes in hemodynamic parameters like mitral valve gradient and area based on pre- and post-intervention measurements.
• Assess clinical improvement in heart failure symptoms based on reported functional class (FC) scores.
• Study patient selection criteria and risk factors based on reported metrics like STS-PROM score and prior thoracotomy history.

Strengths

• Multicenter data from 12 Brazilian hospitals, providing a multi-institutional perspective.
• Includes detailed pre- and post-intervention echocardiographic measurements for 17 patients.
• Reports a median follow-up period of 162 days for assessing sustained outcomes.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single-country study from 2016-2019.
