Rheumatic fever (RF) and rheumatic heart disease (RHD) are major health hazards in developing countries. Affection with RF-RHD in preschool years is uncommon, but prognostically worse as management is technically difficult. We report a rare early presentation of rheumatic valve disease in a 2-year-old child. This is probably the youngest case of rheumatic mitral obstruction documented in literature till date. It highlights that RF-RHD is still a very prevalent disease in India yet is underdiagnosed and underreported.

| Introduction|| |
Acquired mitral stenosis (MS) is mostly considered a “rheumatic fever (RF)-rheumatic heart disease (RHD)” sequelae and juvenile MS term was coined by Dr. Roy Sujoy, which indicates early involvement of valve tissues by this disease. Pediatric and juvenile MS are defined as significant MS up to the age of 12 and 20 years, respectively, RF is still endemic in Southeast Asian, Sub-saharan, and North Australian subcontinents. Critical MS may present in juvenile age in these areas, while the latency period after RF episode extends from 20 to 50 years in developed countries. Up to 50% of RHD patients present without any past history suggestive of RF.
There are only scanty case reports of RHD cases in preschool (<5 year) age group and the youngest such case report was of a 2.5-year-old child.,,,,, Here, we report an unusual case of rheumatic MS in a 1 year and 11-month-old child which is the earliest presentation of RHD-MS ever documented to the best of our knowledge.
| Case Report|| |
A 1-year and 11-month-old female child presented to our hospital with a history of fever, bilateral joint pain, cough, and restlessness for the past 3 weeks after not responding to treatment given by a local pediatrician. The mother also gave a history of respiratory distress and tachypnea. She had a past history of similar fever which lasted for 4–5 weeks at the age of 1.5 years, for which she was treated by the local pediatrician but was not evaluated for possible RF. She was born out of a full-term normal vaginal delivery, had no siblings, and was adequately immunized till date. The family belonged to lower socioeconomic class.
On examination, the child was thin built, had mild pallor, pulse rate was 130/min/regular, and no radiofemoral delay; respiratory rate was 28/min; blood pressure was 90/54 mmHg in RUL; and cardiovascular system examination revealed a tapping apex, loud P2, an apical soft pansystolic murmur, apical mid-diastolic murmur, and a soft pansystolic murmur at the right lower sternal border. Peripheral large joints were tender but showed no other signs of inflammation. The examination of other systems revealed no significant signs and there were no cutaneous manifestations of RF.
Blood investigation revealed hemoglobin of 8.6 g%, very high erythrocyte sedimentation rate (80 mm/h), high C-reactive protein (30), and a very high antistreptolysin O (ASO) titer of 1200 IU/ml, with normal total and differential counts. The patient was admitted under pediatrician's care and was initially treated for suspected connective tissue disorder.
Electrocardiogram revealed sinus tachycardia, right atrial (RA) enlargement, and QRS axis +120°, with normal PR, QRS, and QT interval [Figure 1]. Chest radiograph showed cardiomegaly with right ventricular (RV) type of apex, RA enlargement, splaying of carinal angle indicating left atrial enlargement, characteristic straightening of left heart border, and prominent upper lobe vascular markings indicating pulmonary venous hypertension [Figure 2].

In view of heart murmurs and radiographic findings, transthoracic two-dimensional echocardiography was done, which revealed an enlarged left atrium, thickened anterior and posterior mitral leaflets with restricted mobility with no calcification, and severely thickened subvalvular apparatus up to the papillary muscles. Moderate mitral regurgitation was present [Figure 3]a. The mean gradient across mitral valve was 20 mmHg [Figure 3]d. Maximal leaflet separation was 4 mm [Figure 3]e. There was moderate eccentric tricuspid regurgitation with RV systolic pressure of 55 mmHg [Figure 3]c. Mild regurgitation across the aortic valve was also noted [Figure 3]b. Pulmonary valve and both ventricular functions were normal.

A diagnosis of RHD with probable RF recurrence was made due to characteristic multivalvular involvement and rise of ASO titer along with a history of fever and polyarthralgia. The child was initiated on oral suspensions with weight-based dose of frusemide, spironolactone, digoxin, penicillin, and hematinics. She responded well to treatment and showed symptomatic improvement and weight gain over 6-month follow-up. The parents were counseled regarding the importance of continued RF prophylaxis, close follow-up, and need of surgical intervention in the near future, as surgeons refused to operate in such an early age and as she was responding to the therapy.
| Discussion|| |
RHD is most significant sequelae of RF. It is well known that RHD patients in developing countries have a much shorter latency period after RF episode. The diagnosis of RF in young age is often missed, missing the only opportunity for “primary” prophylaxis. Many patients do not have classical symptoms and suffer from subclinical carditis, indolently damaging the valves.
RHD prevalence in school-aged children varies from 0.6 to 4.5/1000 in India. However, the proportion of RHD cases in <5 year age (pre-school) group is much lower. Our case is probably the youngest documented case of rheumatic valve disease till date. At a time when the occurrence of RF is considered uncommon under 2 years of age, this early presentation of RF and RHD is not only surprising but also a revelation that there is more to learn about RHD pathogenesis and RF-RHD is still a rampant disease in India.
The management of pediatric RHD raises relevant concerns that includes prophylaxis, medication, intervention (timing, mode, and technical difficulties), and probable need of re-intervention (recurrence and increased physiological demand with age).
In conclusion, RF-RHD largely being a disease of the poor and unprivileged, is grossly underdiagnosed, underreported, and undertreated. It is to note that failure to detect and treat RF at young age leads to a huge burden of RHD subsequently, leading to increased morbidity, mortality, and loss of productive years.
