Arrhythmias (Requiring Surgical Intervention)

Arrhythmias are abnormal heart rhythms caused by irregular electrical activity within the heart. While many arrhythmias can be managed with medications or lifestyle changes, some severe or persistent cases require surgical intervention to restore normal cardiac rhythm and prevent life-threatening complications.

Surgical treatment is typically considered when arrhythmias, such as atrial fibrillation, ventricular tachycardia, or heart block, do not respond to conventional therapies. One common procedure is catheter ablation, where targeted energy is used to destroy small areas of heart tissue responsible for abnormal electrical signals. In more complex cases, surgical ablation (Maze procedure) may be performed, creating controlled scar tissue to redirect electrical impulses.

Implantable devices are also widely used. A pacemaker helps regulate slow heart rhythms by sending electrical impulses, while an implantable cardioverter-defibrillator (ICD) detects and corrects dangerous fast rhythms by delivering shocks. In rare cases, open-heart surgery may be required to correct structural abnormalities contributing to arrhythmias.

These interventions aim to restore stable heart rhythm, reduce symptoms like palpitations or fainting, and lower the risk of stroke or sudden cardiac arrest. Proper evaluation and timely surgical management significantly improve patient outcomes and quality of life.
