Clinical Profile and 30-Day Outcomes of Patients with Bicuspid Aortic Valve Undergoing Aor

195 patients with bicuspid aortic valve (BAV) underwent surgical intervention at a tertiary cardiology center from 2014 to 2019. The retrospective cohort study, authored by Marcelo Kirschbaum, found a high prevalence of aortic aneurysm (56.5%) and a 30-day mortality rate of 8.2%. Clinical, echocardiographic, and tomographic data were evaluated alongside intervention characteristics and 30-day events.

Use Cases

• Predicting 30-day composite outcomes (death, atrial fibrillation, reoperation) based on age and left ventricular mass index.
• Analyzing the prevalence of aortic aneurysm and valve dysfunction in a BAV surgical cohort.
• Comparing surgical strategy outcomes (isolated valve, isolated aorta, or combined surgery) for BAV patients.
• Studying demographic and clinical profiles of BAV patients in a Brazilian healthcare setting.

Strengths

• Includes 195 patient records with a mean age of 54±14 years and 73.8% male.
• Contains detailed clinical, echocardiographic, and tomographic data for each patient.
• Reports specific 30-day outcome rates, including 8.2% mortality and predictors from multivariate analysis.
• Covers a defined 5-year time period (2014-2019) from a single tertiary center.

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 institutional bias inherent to a single-center study in Brazil.
