Effects of exercise on transmitral gradient and pulmonary artery pressure in patients with mitral stenosis or a prosthetic mitral valve: A doppler echocardiographic study

Background: Mitral stenosis is often present with pulmonary hypertension. Closed Mitral Commissurotomy (CMC) is a treatment of choice for severe mitral stenosis. In this study, we examined the per-operative changes of pulmonary artery pressure following opening of stenosed mitral valve. Methods: All these CMCs were performed routinely through the left antero-lateral thoracotomy (4th intercostal space) and dilatation was done by metallic Tubb’s Dilator. Peroperative left atrial and Pulminary Arterial pressures were measured before and after dilatation. Results: 15 patients had undergone CMC. Following CMC, per-operative mean Pulmonary artery pressure was reduced from 45.5±7.1 mm of Hg to 39.0±8.8 mm of Hg (p=0.043). Mean left atrial pressure reduced from 35.9±5.6 mm of Hg to 30.0±9.1 mm of Hg (p = 0.049). At three months follow up after closed mitral commissurotomy mitral valve area at echocardiography was found 2.29±0.18 cm2. There was no case of death after closed mitral commissurotomy. Mild mitral regurgitation occurred in 1 patient. Conclusion: We conclude that there is immediate significant reduction of pulmonary Artery pressure following closed mitral commissurotomy. This reduction is apparently comparable with a similar reduction of left atrial pressure. Cardiovasc. j. 2019; 11(2): 147-151

Background: Rheumatic valvular heart disease, commonly mitral stenosis, complicate 1% of pregnancies. Balloon mitral valvuloplasty (BMV) is an established treatment of rheumatic mitral stenosis. Aim of the study was to assess the safety and efficacy of Balloon mitral valvuloplasty in pregnant women with severe mitral stenosis. Materials and Methods: 66 patients who failed to respond to medical therapy undergoing BMV during pregnancy were analysed in this retrospective study. Mitral valve area (MVA), transmitral Mean valve gradient (MVG), and mitral regurgitation (MR), Pulmonary artery pressure (PAP) were assessed before and 24 hours after the procedure by transthoracic echocardiography. Patients were followed up to one month post BMV and neonates were monitored for the adverse effect of radiation. Results: Mitral valve area increased from 0.83 ± 0.13 cm2 to 1.38 ± 0.29 cm2 (P = 0.007). Mean gradient mitral valve gradient decreased from 15.5 ± 7.4 mmHg to 3.36 ± 2.36 mmHg (P = 0.001). Pulmonary artery pressure decreased from 65.24 ± 17.9 to 50.45 ± 15.33 (P = 0.012). No maternal death, intrauterine growth restriction was observed. Conclusion: Balloon mitral valvuloplasty has favourable immediate good outcomes for mothers and newborns.
