RESUMEN
Objective: To know the regression of right ventricular pressure after successful percutaneous transluminalmitral commissurotomy [PTMC] in patients with severe isolated mitral stenosis
Methods: This descriptive study was performed in inpatient and outpatient department of National Institute of Cardiovascular Disease from 1[st] February 2016 to 31[st] August 2016. Echocardiography of all patients with successful PTMC were recorded 24 hours and 06 months following PTMC to see for Regression of right ventricular pressure along with other baseline echocardiographic parameters
Results: A total of 99 patients with severe isolated mitral stenosis who had undergone successful PTMC were studied. Females were 65[65.7%] and males 34[34.3%]. Mean age was 27.44 +/- 6.26 years. TTE performed before and after PTMC showed significant difference in mean mitral valve area [0.89cm +/- 0.089cm[2] vs. 1.68 +/- 0.128 cm[2], p valve <0.001] and mean left atrial diameter [4.66 +/- .82cm vs. 4.46 +/- 0.65cm]. Mean mitral valve gradient pre PTMC was significantly higher [16.38 +/- 2.51 mm of Hg] than that of post PTMC 24 hours [4.75 +/- 1.31 mm of Hg] and Post PTMC 06 months [5.22 +/- 1.21 mm of Hg], p valve <0.001. Mean right ventricular systolic pressure [RVSP] pre PTMC was significantly higher 62.3 +/- 10.91 mm of Hg than that of post PTMC 24 hour's 57.51 +/- 9.67 mm of Hg and post PTMC 06 moths 46.49 +/- 7.8mm of Hg, p value 0.001. Mean LVEF 50.14 +/- 5.82
Conclusion: There was a significant regression of right ventricular pressure following successful PTMC in mid-term [06 months] follow up of severe isolated mitral stenosis patients
RESUMEN
In routine coronary angiography, bifurcation lesion is not uncommon. Current practice of dealing with type 4a coronary bifurcation lesions [lesions of main branch without significant lesions of the side branch] may lead to true bifurcation lesions after stenting due to axial plaque redistribution. This series describes an experience with Greek technique for treatment of type 4a bifurcation lesions in 18 patients for primary stenting of main vessel with simultaneous kissing balloon of side branch in an effort to avoid snow plough effect
