Tucson Myofilament Meeting, May 23-26

The Tucson Myofilament Meeting is an international 3.5-day Sarver Heart Center conference that brings together approximately 250 scientists focused on the structure and function of the myofilaments that comprise the contractile machinery of muscle. Spanning topics from molecular biophysics to heart and skeletal muscle disease mechanisms and drug development, the meeting is known for its highly interactive, collaborative, and informal atmosphere, with strong engagement of early career investigators.

Traditionally held biennially at the University of Wisconsin, the meeting will continue at the University of Arizona beginning in May 2026, offering a distinctive Tucson setting that fosters scientific exchange and community building.

Heart Rhythm Disorders

The Heart Rhythm Disorders program at the University of Arizona Sarver Heart Center focuses on the evaluation and management of complex cardiac arrhythmias. The program brings together electrophysiologists, cardiovascular specialists, and researchers dedicated to advancing the understanding and treatment of abnormal heart rhythms.

Cardiac arrhythmias occur when the electrical signals that coordinate the heartbeat become disrupted. These conditions can lead to symptoms such as palpitations, dizziness, shortness of breath, or fainting and may increase the risk of stroke or heart failure if left untreated.

At the Sarver Heart Center, electrophysiology specialists focus on the diagnosis and treatment of atrial and ventricular arrhythmias using advanced imaging, mapping technologies, and catheter-based therapies. The program integrates clinical expertise with research efforts aimed at improving long-term outcomes for patients with rhythm disorders.

Advanced electrophysiology procedures allow specialists to diagnose and treat complex heart rhythm disorders.

Program Themes

Atrial Fibrillation and Complex Arrhythmias

Atrial fibrillation is the most common cardiac arrhythmia and a major contributor to stroke and cardiovascular morbidity. The program focuses on advanced evaluation and management strategies for atrial fibrillation and other complex atrial arrhythmias.

Catheter Ablation

Catheter-based electrophysiology procedures allow specialists to identify and treat abnormal electrical pathways responsible for arrhythmias. Ablation therapies are used to treat atrial fibrillation, atrial flutter, supraventricular tachycardia, and certain ventricular arrhythmias.

Cardiac Devices

Implantable cardiac devices such as pacemakers and implantable cardioverter-defibrillators (ICDs) play a critical role in the treatment of heart rhythm disorders. These technologies help regulate heart rhythm and prevent life-threatening arrhythmias.

Ventricular Arrhythmias

The program also focuses on ventricular arrhythmias, including premature ventricular contractions (PVCs) and ventricular tachycardia, which may arise from structural heart disease or inherited cardiac conditions.

Inherited Arrhythmia Syndromes

Specialized expertise is available for rare and inherited arrhythmia disorders such as arrhythmogenic right ventricular cardiomyopathy (ARVC/D). These conditions often require advanced diagnostic evaluation and multidisciplinary management.

Research and Innovation

Electrophysiology investigators at the Sarver Heart Center are actively involved in research aimed at improving the understanding of cardiac electrical disorders and developing new therapies for atrial fibrillation and related arrhythmias.

Ongoing research efforts include studies of arrhythmia mechanisms, clinical outcomes of catheter ablation procedures, and the development of new technologies for mapping and treating abnormal cardiac electrical activity.
