Latest Videos See All How a year's worth of experience of pulsed field ablation for AFib has revolutionized my practice Pulsed field ablation is transforming atrial fibrillation treatment. After over one year's experience, cardiac electrophysiology experts Christopher DeSimone, M.D., Ph.D. , and Abhishek J. Deshmukh, M.B.B.S., explore how pulsed field ablation (PFA) has reshaped the treatment of atrial fibrillation and changed clinical practice in electrophysiology. Vascular rings and slings: Mayo Clinic experience Vascular rings and slings are increasingly diagnosed with the advent of fetal screening and frequency of cross-sectional imaging. There are a wide variety of types, and management depends on anatomy, age and symptoms. Novel mitral therapies — A Mayo Clinic perspective Mayo Clinic heart specialist Kyle W. Klarich, M.D., interventional cardiologist Mayra Guerrero, M.D., and cardiovascular surgeon Arman Arghami, M.D., M.P.H., discuss the advantages of minimally invasive surgical and interventional approaches. They also provide recommendations on the optimal time to refer patients for intervention or surgery.
