|Official Title:||Prospective Pilot Study of Assessment of Breath Hold as a Means to Mitigate the Risk of Radiation-associated Reductions in Regional Cardiac Perfusion in Patients With Left-sided Breast Cancer|

Women with left-sided breast cancer
Other: Cardiac SPECT perfusion scan
A SPECT cardiac perfusion scan provides a three-dimensional map of blood flow to the heart tissue. The scan will be taken at rest only.
- Changes in cardiac perfusion [ Time Frame: 6-months post radiation ]Cardiac perfusion will be assessed using SPECT cardiac perfusion scans pre- and 6 months post-radiation. Any post-radiation summed-rest score (SRS) > 0 will be counted as a perfusion defect in the calculation of the perfusion defect rate.
- Wall-motion abnormalities [ Time Frame: 6-months post-treatment ]The incidence of wall-motion abnormalities will be assessed using SPECT in the same 12 segment scoring system used to quantify perfusion. Wall-motion abnormalities will be recorded as present or absent in each cardiac segment. When present, wall-motion abnormalities wil be classified as gypokinetic, akinetic, or dyskinetic. The extent of wall involvement (small or large portion) will be described as mild or severe.
