“…In this retrospective study, we found that the prevalence of chronic rheumatic heart disease was 186/100,000 adults and 10 times higher than the prevalence in industrialized countries such as Canada (0.22/1000) and Japan (0.14/1000) [9,10]. It is thus a significant health burden in China.…”

Objective:To evaluate the short- and mid-term effects of percutaneous mitral balloon valvuloplasty (PMBV) on right ventricular functions in mitral stenosis.Methods:A prospective study was conducted in 61 patients who had mitral stenosis in normal sinus rhythm (68% female, age: 42±11-16 years). Right ventricular functions were measured before, immediately after, and at 3 months and 1 year after PMBV by conventional and tissue Doppler echocardiography imaging methods. Additionally, the patients were evaluated in two groups (PAP≥40 mm Hg, n: 46; PAP<40 mm Hg, n: 15) according to the systolic pulmonary artery that was measured by echocardiography prior to PMBV.Results:Post-PMBV mean gradient, pulmonary artery pressure (PAP), and left atrial size decreased significantly, and the mitral valve area increased significantly in both patient groups. This significance in pulmonary artery pressure was lost at 1 year. The significant post-PMBV increase in tricuspid annular point systolic excursion (TAPSE), systolic velocity, early diastolic velocity, and peak myocardial velocity during isovolumic contraction (IVV), indicating right ventricular functions, disappeared at 1 year. The significant post-PMBV decrease in myocardial performance index (MPI) and late diastolic velocity lost its significance at 1 year. No significant change was observed in myocardial acceleration during isovolumic contraction (IVA). The group with pulmonary hypertension demonstrated significance similar to the results of the overall group. Post-PMBV TAPSE, systolic velocity, early diastolic velocity, IVV, and IVA increased significantly, and this increase was maintained up to 1 year in the group without pulmonary hypertension. MPI and late diastolic velocity maintained their significantly decreased values up to 1 year.Conclusion:The positive effect of PMBV on right ventricular function in the acute period decreases and even disappears in the mid-term in patients developing pulmonary hypertension. Intervention in the patients prior to the development of hypertension is very important for the improvement in right ventricular functions.

“…According to the annual report by the World Heart Federation, an estimated 12 million people are currently affected by rheumatic fever and rheumatic heart disease worldwide, and high incidence rates are reported in the Southern Pacific Islands. Several studies were conducted on the prevalence of rheumatic heart disease, reporting 0.14/1000 in Japan, 1 1.86/ 1000 in China, 2 0.5/1000 in Korea, 3 4.54/1000 in India, 4 and 1.3/1000 in Bangladesh. 5 In rapidly evolving Asian countries, awareness of rheumatic heart disease has prevailed along with the widespread use of transthoracic echocardiography.…”
