    Electrophysiology

    Biography

    Luciano C. Amado, MD is a cardiologist and electrophysiologist, board certified in cardiovascular disease, and a member of the Heart Rhythm Society. He is a recognized expert on catheter ablation, atrial fibrillation, sudden cardiac death, and arrhythmia management. 

    Dr. Amado specializes in atrial arrhythmia ablation (Afib, flutter, SVT, and Atach), ventricular arrhythmia (PVCs and VT), and device implantation (including pacemaker, defibrillator, and left atrial appendage closure devices). He has a particular interest in management of atrial arrhythmias and new device technologies. 

    After completing cardiology and electrophysiology training at The Johns Hopkins Hospital, Dr. Amado stayed an additional four years researching cardiac imaging, cell regeneration, and advanced therapies for atrial and ventricular arrhythmias. Afterwards, he joined the faculty team at Washington University in St. Louis as an assistant professor of cardiology/electrophysiology, and later he moved to Minneapolis, where he joined the University of Minnesota Physicians group.

    In his free time, Dr. Amado enjoys spending time with his family, as well as exercising and playing soccer.
