Brief Summary:
In the absence of treatment, severe mitral valve regurgitation (MR) results in left atrium (LA) dilatation and hypertrophy, followed ultimately by left ventricular dysfunction and heart failure. One promising intervention for the prevention of the deleterious effects of pressure overload-induced cardiac hypertrophy and heart failure is dietary supplementation with n-3 polyunsaturated fatty acids (PUFAs). However, the molecular targets and mechanisms by which n-3 PUFAs exert their effects are not completely defined. A possible target of n-3 PUFAs is the mitochondrial membrane which has broad implications given that mitochondrial dysfunction and altered metabolism have been associated with cardiac hypertrophy and heart failure. The investigators have recently identified significant mitochondrial dysfunction in the LA of patients with severe MR, as compared to their non-hypertrophied right atrium (RA). However, the investigators have not addressed the possibility that intervention with purified n-3 PUFAs (Lovaza) could improve mitochondrial function. From a mechanistic perspective, the investigators have observed in vitro that n-3 PUFAs accumulate predominately into the mitochondrial membrane of cardiomyocytes where the investigators believe they exert their effects on the biophysical organization of the membrane. Therefore, the CENTRAL HYPOTHESIS is that administering Lovaza to patients with severe MR will reduce apoptosis and improve mitochondrial function in LA (Aim 1). This change in mitochondrial function will be driven by significant biochemical and biophysical remodeling of the mitochondrial membrane (Aim 2).
