To evaluate the clinical outcomes and hemodynamic changes after recreating spontaneously closed fenestration in Fontan patients over a defined follow-up period.
Key Findings:
No significant differences in baseline characteristics between the two groups.
Group 1 had a median interval of 42 days from Fontan completion to fenestration re-canalization.
Longitudinal hemodynamic changes were assessed, revealing specific differences in outcomes between the two groups.
Interpretation:
Recreating fenestration in Fontan patients with spontaneous closure may improve clinical outcomes and hemodynamic status, although further studies with larger sample sizes are needed to confirm these findings.
Sample size may not be sufficient to generalize findings.
Conclusion:
Fenestration re-canalization may serve as a beneficial intervention for selected Fontan patients experiencing early decline, warranting further investigation.
A cohort study showed that patients with melanoma who received BRAF or MEK inhibitor therapy commonly experienced hypertension and mild cardiac dysfunction, supporting baseline cardiotoxicity risk str...
