About Ayman Hussein, MD

Ayman A. Hussein, MD, is a specialist in heart rhythm disorders in the Section of Cardiac Electrophysiology and Pacing, Robert and Suzanne Tomsich Department of Cardiovascular Medicine, Sydell and Arnold Miller Family Heart, Vascular & Thoracic Institute. He sees patients at Cleveland Clinic Main Campus.

Specialty Interests: Management of heart rhythm disorders; catheter ablation for supraventricular and ventricular arrhythmias, including complex catheter ablations for atrial fibrillation and ventricular tachycardia; stroke prevention in atrial fibrillation, including left atrial appendage closure; cardiac device therapy, including implantation and extraction of cardiac pacemakers, implantable cardiac defibrillators (ICDs) and cardiac resynchronization therapy (CRT) using bi-ventricular devices; sudden cardiac death and inherited arrhythmia (abnormal heart rhythm) syndromes, including long QT syndrome

Number of Patients Treated: Physicians in the Section of Cardiac Electrophysiology and Pacing performed approximately 4,000 electrophysiology procedures in 2015. Dr. Hussein has performed more than 600 electrophysiology procedures in the past two years.

Success Rates: Treatment for atrial fibrillation using a technique known as pulmonary vein antrum isolation (PVAI) accounts for approximately 20 percent of electrophysiology procedures at Cleveland Clinic annually. Success rates for this procedure range from 65 percent for patients with persistent or long-standing atrial fibrillation to greater than 80 percent for patients with less-persistent atrial fibrillation.

Electrophysiology treatment at Cleveland Clinic for patients with ventricular arrhythmias (abnormal rapid heart rhythm originating in the heart’s lower chambers) completely eliminates the arrhythmia in nearly 80 percent of patients and eliminates at least one arrhythmia in 15 percent of patients with multiple arrhythmias.
