* Subject must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent

* Pregnant or nursing female subjects, determined preoperatively with a urine pregnancy test
* Unwilling or unable to follow protocol requirements
* Any condition which in the investigators' opinion deems the patient unsuitable (e.g., abnormal electrocardiography \[EKG\], including T wave inversion, elevated T waves, prolonged QRS interval, or conduction blocks) or that requires further work-up (including cardiac echo or stress test)
* Any condition that excludes surgical resection as the standard of care for the patient
