Abstract
Rheumatic heart disease is one of the most common heart
diseases in developing country. One of the most common
complications of Rheumatic Heart Disease is Mitral Stenosis
which ultimately lead to pulmonary hypertension and heart
failure and death. So, PTMC (Percutaneous Transluminal
Mitral Commissurotomy) is a well-established simple, effective
and safe therapeutic intervention for mitral stenosis. While
many literatures reviewed till date have shown that it takes 3-6
months time period for the reduction of pulmonary artery
pressure after PTMC, this study is designed to see the result in
pulmonary artery pressure immediately after procedure.
Method
Total 42 patients with Rheumatic Mitral Stenosis in Cath Lab under Department of Cardiology of Chitwan Medical College from October 1 2018 to August 30 2019 were included in the study. Pulmonary artery pressure was assessed by Right heart catheterization by using multipurpose /pigtail catheter under conscious sedation.
Results
It is a prospective observational study on a total of 42 patients
who underwent PTMC, 30 were female and 12 were male. Age
ranged from 30 to 61 years with the mean age of 45.36±10
years. The mean mitral valve area increased from 0.87±0.2 cm2
to 1.74±0.17 cm2 whereas Mean Pressure Gradient decreased
from 13.59± 7.30 mmHg to 5.15±30 mmHg. Mean Pulmonary
Artery Pressure decreased from 41.50 ±16.00 mmHg to
33.50±12.00 mmHg. Similarly, the mean left atrial pressure
decreased from 26.57±8.62 mmHg to 15.50±5.95 mmHg
whereas, the mean Aortic Pressure increased from 91.43 ±23.02
mmHg to 98.29±24.92 mmHg . Eighteen (42.85%) patients
had an increase in MR by 2 grades but there is no need of
immediate mitral valve replacement. During procedure,paroxysmal PSVT was noted in six
(14.285%) patients and also local hematoma
was observed in five (11.90%) patients.
Conclusion
There is reduction in pulmonary artery pressure immediately
post PTMC which is directly correlated with left atrial pressure
without significant MR and tachycardia. This study is limited in
terms of single center with small sample size.
