His‐Bundle Pacing for Pulmonary Hypertension With Bradycardia in Congenital Heart Disease: A Case Report

Bradycardia, atrial tachyarrhythmia, heart failure, residual shunts, and pulmonary hypertension (PH) are significant problems after congenital heart disease surgery. We performed His-bundle pacing (HBP) for drug-resistant PH with bradycardia in a woman post-total anomalous pulmonary venous return repair complicated by bradycardia, hypertension, PH, residual atrial shunts, and heart failure. Significant improvement in PH post-HBP was achieved without exacerbation of left ventricular function. We successfully closed the atrial shunts 12 months after HBP.
