More of the Heart's Secrets Revealed

Using new, high-resolution imaging methodology, Mayo Clinic researchers have discovered an important link between the structure and function of a beating heart. The advanced imaging allows researchers to observe the unique geometry of the left ventricle and can more precisely provide data for calculating heart strain and other cardiac impairment.

"Current biological models for understanding heart failure are insufficient for explaining both how the beating heart functions and the benefits of several new, emerging therapies," explains Dr. Bijoy K. Khandheria, senior author of the study. He adds that conventional imaging methods do not allow for complex study of the three-dimensional pattern of ventricular activation and contraction.

The new, evolved imaging can lead to better planning for surgeries to correct malfunctioning or failing hearts, and could ultimately contribute to the design of a bioartificial heart, Dr. Khandheria notes.

Mayo Clinic physician staff includes more than 170 cardiovascular specialists. For more about the clinic's heart care, go to: www.mayoclinic.org/heart-care/.
