Prevalence, risk determinants and consequences of atrial fibrillation in rheumatic heart disease: 6 years hospital based-Himachal Pradesh- Rheumatic Fever/Rheumatic Heart Disease (HP-RF/RHD) Registry

Objective To report the prevalence, risk factors and consequences of atrial fibrillation (AF) in patients of rheumatic heart disease (RHD). Methods The Himachal Pradesh- Rheumatic Fever/Rheumatic Heart Disease (HP-RF/RHD) Registry database of 1918 patients was analyzed. AF was diagnosed with 12-lead ECG recording at entry in to the registry. The association of AF with nature and severity of valvular dysfunction was analyzed, adjusted for age, left atrial (LA) dimension and pulmonary arterial hypertension using multivariable logistic regression model and strength of association was reported as odds ratio (OR) with 95% confidence intervals (C. I.). Results The study population consisted of young (40.2 ± 14.3 years), predominantly females (72.3%) from rural area (94.1%). Prevalence of AF was 23.9% (95% C. I. 22.1%–25.8%). The independent determinants AF were age (OR 1.04, 95% C.I. 1.03–1.06), LA size (OR 1.10, 95% C.I. 1.08–1.11). The association of AF with age, New York Heart Association functional class, mitral stenosis severity and tricuspid regurgitation was statistically significant and graded. Mitral regurgitation and aortic valve disease had no significant independent association with AF. The prevalence of heart failure, stroke, peripheral embolism and mortality was significantly higher among patients with AF (p < .01). Conclusion AF is common in RHD patients and is significantly associated with heart failure and systemic thromboembolism. Age, mitral stenosis severity, tricuspid regurgitation and LA size were independently associated with AF.

School-based surveillance for detection of children with acute pharyngitis, rheumatic fever/rheumatic heart disease in Shimla district, Himachal Pradesh, India—A cluster randomized controlled trial

Background The lack of surveillance system is a major barrier in prevention and control of rheumatic fever/rheumatic heart disease (RF/RHD). Efficacy of school-based surveillance was evaluated for detection of acute pharyngitis and RF/RHD in Shimla district, HP. Methods The schools in district Shimla were randomly assigned to intervention and controlled arm (442 vs. 441 schools). The trained nodal teachers reported children with symptoms of acute pharyngitis and or RF/RHD in intervention arm and children taken to hospitals by parents for symptoms of acute pharyngitis and or RF/RHD under control arm through mobile phone to coordinating centre. Final outcome for presence of RF/RHD or other heart Diseases was recorded after examination at nearest primary health centers and/or at Indira Gandhi Medical College Hospital, Shimla. Difference in detection rate between intervention arm and control arm was compared using Z test. Results The number of school children reported from intervention group was significantly higher than in control due to suspected symptoms of acute pharyngitis and or RF/RHD were 65 (2.84/1000) and 15 (0.60/1000), respectively (p < 0.01). Only 4 children in each arm were found to have heart diseases, with prevalence of (0.17/1000 and 0.16/1000), respectively, after clinical and echocardiography evaluation. In intervention arm, one child had RHD while three had congenital heart disease; in control arm, one child had congenital heart disease and three had RHD. Conclusions School based surveillance had higher rate of suspecting children with acute pharyngitis and or RF/RHD although with low specificity. There is a need of future studies to demonstrate the effectiveness of the proposed intervention in endemic regions of the state.

Superior mesenteric artery occlusion as the manifestation of left atrial myxoma: an extremely rare occurrence

A 62-year-old woman was presented to the surgical ward, with severe abdominal pain and vomiting. She had sinus tachycardia (135/min) and her blood pressure was 80/60 mm Hg. The physical examination revealed generalised abdominal distension with signs of peritonitis. Laboratory parameters revealed polymorphonuclear leucocytosis (total leucocyte count of 21 000/mm3 with 88% neutrophils), blood urea nitrogen=74 mg/dL and serum creatinine=2.1 mg/dL. X-ray of the abdomen showed air under the diaphragm. CT angiography revealed absence of contrast beyond the mid segment of the superior mesenteric artery (SMA) (figure 1). A large filling defect was noted in the left atrium (LA) on CT scan …
