Exercise radionuclide ventriculographic study of mitral stenosis before and after percutaneous mirtal valvuloplasty

Journal Article:

Abstract

We performed radionuclide ventriculography before and within 1 week after percutaneous mirtal valvuloplasty (PMV) to evaluate left ventricular (LV) function in 20 patients (2 meals and 17 females, mean age of 38 {+-} 10 years) who were pure mitral stenosis before PMV and less than grade 1 mirtal regurgitation developed after PMV. 9 out of 20 patients had atrial fibrillation and 3 patients developed a small left-to-right shunt (Qp/Qs < 1.5) after PMV. PMV using double-balloon technique resulted in a increase in mitral valve area (0.9 {+-} 0.3 to 2.1 {+-} 0.8cm{sup 2}, {rho} < 0.001) and in rest cardiac output (4.2 {+-} 1.0 to 4.8 {+-} 1.4 L/min, {rho} < 0.005). And also a decrease in mean mitral gradient (16.2 {+-} 7.0 to 5.2 {+-} 3.0 mmHg, {rho} < 0.001) was noted. Comparisons of LV function by supine bicycle exercise radionuclide ventriculography before and after PMV showed no significant changes in rest LV ejection fraction (LVEF, 55.2 {+-} 9.7 to 56.1 {+-} 11.0%, {rho} > 0.05), maximal exercise LVEF (60.9 {+-} 10.3 to 59.3 {+-} 11.1%, {rho} > 0.05), peak ejection rate (2.02 {+-} 0.58 to 2.15 {+-} 0.60 EDV/ses, {rho} > 0.05), and peak filling rate (1.04 {+-}  More>>

However, LV end diastolic volume (LVEDV, -29.3 {+-} 19.0 to +3.3 {+-} 32.9%, {rho} < 0.001), stroke volume (SV,-22.0 {+-} 22.0 to +11.2 {+-} 40.0%, {rho} < 0.001), and cardiac output (CO, 64.6 {+-} 54.0 to 100.4 {+-} 69.7%, {rho} < 0.05) with exercise compared to resting values were significantly increased. We conclude that PMV resulted in a significant increase in LVEDV, SV, and CO with exercise, but decreased LV systolic performance and no improvement in diastolic filling.}
