Unilateral Hip Resurfacing
Patients who received either right or left total hip resurfacing procedure. This group of patients will undergo a cardiac magnetic resonance imaging (CMR). Cardiac magnetic resonance imaging (CMR): Cardiac MRI is used to assess cardiac function in patients at risk of cardiotoxicity. In addition, Cardiac MRI enables imaging of inflammation, and fibrosis in the heart which may provide more specific information about the mechanism of injury in patients with high ion blood levels. Patients in all three groups (Unilateral hip resurfacing, bilateral hip resurfacing, and non-metal on metal total hip arthroplasty) will undergo a Cardiac MRI.
Bilateral Hip Resurfacing
Patients who received both right and left hip resurfacing procedure on the same day. This group of patients will undergo a cardiac magnetic resonance imaging (CMR). Cardiac magnetic resonance imaging (CMR): Cardiac MRI is used to assess cardiac function in patients at risk of cardiotoxicity. In addition, Cardiac MRI enables imaging of inflammation, and fibrosis in the heart which may provide more specific information about the mechanism of injury in patients with high ion blood levels. Patients in all three groups (Unilateral hip resurfacing, bilateral hip resurfacing, and non-metal on metal total hip arthroplasty) will undergo a Cardiac MRI.
Non-Metal on Metal Total Hip
Patients who received either a unilateral (one hip) or bilateral (both hips) non-metal on metal total hip arthroplasty. This group of patients will undergo a cardiac magnetic resonance imaging (CMR). Cardiac magnetic resonance imaging (CMR): Cardiac MRI is used to assess cardiac function in patients at risk of cardiotoxicity. In addition, Cardiac MRI enables imaging of inflammation, and fibrosis in the heart which may provide more specific information about the mechanism of injury in patients with high ion blood levels.
