Coronary arterial pressure and flow are known to influence left ventricular (LV) diastolic distensibility, but the influence of coronary venous pressure is unknown. To test the hypothesis that increased coronary venous pressure leads to an increase in LV wall volume and a decrease in LV diastolic di...
