Objective:To investigate the effect of left ventricular size on the clinical outcome and prognosis of the patients with mitral stenosis and atrial fibrillation undergoing mitral balloon angioplasty. Methods:216 patients with mitral valvuloplasty were followed up, 80 cases of mitral stenosis with atrial fibrillation (atrial fibrillation group), 136 cases of sinus rhythm (sinus rhythm group), the risk factors of early event were analyzed through the return visit. Results:Before treatment, the difference of left ventricular end-diastolic diameter index(LVEDDI) between the two groups was statistically significant(P<0.05); after treatment, the differences of the mean left atrial pressure, mitral orifice area, LVEDDI, mitral valve plasty again, mitral valve regurgitation between the two groups were statistically significant(P<0.05), and the LVEDDI was an independent risk factor for atrial fibrillation, and LVEDDI>36 mm·m-2 was more prone to early risk events than LVEDDI ≤ 36 mm·m-2.Conclusion:Mitral balloon angioplasty for the mitral stenosis with atrial fibrillation has a good effect when the LVEDDI isn't more than 36 mm·m-2. |
