Background: Rheumatic Fever (RF) and Rheumatic Heart Disease (RHD) as its sequelae are decreasing in most Asian countries, however, the occurrence of Rheumatic MS continues to exist in Asia. Percutaneous Balloon Mitral Valvotomy (PBMV) delays the need for MV replacement for about 10 years or more. The objective of this study was to identify the clinical profile and outcomes of patients undergoing PBMV at the Philippine Heart Center from 2005 to 2012.
Method: We conducted a descriptive study of all patients diagnosed with Rheumatic MS who underwent PBMV at Philippine Heart Center from 2005 to 2012. Patients were enrolled retrospectively. Registry data of the Department of Education, Training and Research of the Philippine Heart Center were reviewed for eligible subjects. Exclusion criteria includes previous valvular surgery done, valvular MS of other etiology, presence of thrombus and severe MR on 2D echo and absent mitral valve area results before and after the PMVB. Patient's demographics, clinical findings, laboratory' and imaging study results, and outcomes were recorded. Results are presented in tables with corresponding number or frequency and percentage distribution.
Result: A total of 91 patients met the inclusion and exclusion criteria and were included in this study. Majority of patients were aged less than 40 years old (66%) with an average age of 37.4 years. Mostly are females (75%) and single (60%). Difficulty of breathing was seen in 65%, followed by easy fatigability at 63%.Heart failure symptoms were noted in 60 patients (66%). Upon admission, 67 patients (74%) presented with sinus on ECG and 24 patients (26%) are in AF. Chest x-ray showed congestion in 12%, dilated main pulmonary artery in 33% and cardiomegaly primarily involving the left atrium at 36%.
