86 year old woman with aortic stenosis with valve area of about 0.65 cm2. Ao V2 max of 4.5 m/sec HG. Ao max PG of 77 mm HG. Ao max PG (full) 54.7 mm HG. Ao mean PG 47.0 mm HG. Mild aortic regurgitation. Aortic valve has severe calcification. Recently had symptoms of shortness of breath except when at rest, which is now treated with 3 liters/min supplementary oxygen 24 hours/day to maintain an oxygen saturation level of about 98%. No other symptoms of aortic stenosis have ever developed. Severe mitral valve regurgitation of about two years duration which is presently adequately controlled with 80mg lasix / day, a low sodium (less than 1000 mg salt/ day ) and highly restrictive fluid intake diet (less than 1500 ml/day). At least a moderate level of tricuspid valve regurgitation with a RVSP of at least 70-75mm HG. Pulmonary valve is normal in structure and function. Severe pulmonary hypertension. Severe biatrial enlargement. Severe concentric left ventricular hypertrophy. Hyperdynamic left ventricle systolic function. LVEF more than 70%. Elevated LA pressures. Both the left and right atrium are severely dilated.. Left atrial volume index is 86 ml/m2. Ejection Fraction is more than 55%. Never has had any other heart issues. Never smoked a cigarette or cigar in her life. Angiogram had perfect results. Normal EKG. Blood pressure at rest consistently in the range of about 100/ 55 with a pulse rate at rest of about 75 beats / minute. Low glomerular filtration rate of 30%. This GFR has been consistently between 30% and 35% for the last two years. Slightly elevated blood sugar of 6-7 mmol/liter. Predominately sedentary lifestyle. Appears frail, but weight is well within the normal range for her height. No other chronic health issues. Is very ambivalent about pursuing medical options to replace/repair heart valves. Without surgical/medical intervention, what is the best estimate of how long this 86 year old woman can expect to live?
