Background Rheumatic heart disease (RHD) is endemic in sub-Saharan Africa where it is the leading cause of cardiovascular mortality in the young. Rheumatic heart disease results from recurrent episodes of acute rheumatic fever (ARF), which are often difficult to diagnose clinically. Acute rheumatic fever may be diagnosed based on the revised Jones Criteria 2015 for the diagnosis of ARF. Histologically, acute rheumatic valvulitis manifests with active inflammation characterized by lymphocytic infiltration, Aschoff bodies, and Anitschkow cells. Chronic rheumatic valvulitis is associated with neovascularization, and/or dystrophic calcification. The combination of histological features of both ARF and chronic RHD is a rare finding. Case summary Here we report on a case of a 59-year-old woman with mixed aortic and mitral valve disease of probable rheumatic aetiology (elevated C-reactive protein and prolonged PR interval) and with histological evidence of lymphocytic infiltration, Aschoff bodies, and fibrinoid necrosis admixed with features of chronic RHD. Discussion Cases of chronic RHD admixed with ARF are very rare; however, they should be considered in regions with a high prevalence of RHDs.

Background Right ventricular aneurysms (RVAs) are rare. We present a case with a combined RVA and right ventricular pericardial fistula resulting in a pericardial effusion and cardiac tamponade. The RVA was detected 47 days after the patient suffered a gunshot wound. This report adds to the body of scarce literature on RVA aetiology, diagnoses, and treatment. Case summary A 30-year-old male patient presented with worsening respiratory distress over a 7-day period with clinical signs of cardiac tamponade following a history of a gunshot (with associated liver laceration, pulmonary embolism, right nephrectomy, and sepsis) 47 days prior. Transthoracic echocardiography showed a large circumferential pericardial effusion and an RVA. The patient was emergently taken for surgical repair of the RVA. Discussion Our case presents a delayed presentation of a gunshot heart and an aetiology with indications of and against a true aneurysm. It brings attention to possible complications of penetrating precordial injuries, with the need for consideration and possible evaluation at follow-up. The literature on the operative excision of RVA is reviewed and various aetiological factors and consequences are discussed.

Objective Although the results of aortic valve replacement are well documented for industrialized countries, the outcome in patients with rheumatic aortic valve disease in low- to middle-income countries is less well explored. The aim of this study was to determine the long-term survival and clinical outcomes after isolated aortic valve replacement in patients with rheumatic heart disease in a Sub-Saharan country where follow-up of indigent patients is often challenging. Methods A retrospective review of 969 aortic valve replacements performed between 2003 and 2013 was conducted at Cape Town's Groote Schuur Hospital. Patients who underwent concomitant procedures (n = 664) or had nonrheumatic valve pathology (n = 185) were excluded. The mean age of the rheumatic cohort (n = 121) was 43.1 ± 11.6 years with a mean follow-up period of 6.14 ± 3.44 years. The primary end points were survival and valve-related complications. Results A 15% cardiac- or valve-related 10-year mortality after receiving a mechanical prosthesis corresponded with a significantly higher mortality rate than that of a matched population. Overall cumulative survival at 1, 5, and 10 years was 93.5% (87.0-96.9), 86.4% (78.4-91.8), and 78.1% (67.5-86.0), respectively, and the corresponding cumulative freedom from combined thromboembolism and bleeding was 94.4% (88.2-97.5), 87.4% (79.4-92.5), and 86.1% (77.9-91.6), respectively. Conclusions In low- to middle-income countries, with their unique mix of indigent and “First World” patients, rheumatic heart disease still accounts for a significant proportion of patients requiring isolated aortic valve replacement. Although mechanical prostheses are often selected in these young adults, survival remains suboptimal. Major bleeding and thromboembolic events account for the majority (77%) of the reported valve-related complications.

Introduction Thoracic injuries continue to be a leading cause of childhood trauma, despite the government's efforts to curb the scourge of this problem. Our review focuses on the incidence, etiology, and management of thoracic trauma in the pediatric population with reference to the recent experience at our institution in a developing country. Methods For the literature review, the National Library of Medicine's PubMed database was searched for the following terms: “pediatric,” “chest trauma,” “hemothorax,” “hemopneumothorax,” “pneumothorax,” “diaphragmatic,” “esophageal,” and “mediastinal injury.” For the hospital data analysis, data of all 378 pediatric patients treated with thoracic injuries under the age of 13 years from 2008 to 2012 (a 5-year period), at the Red Cross War Memorial Children's Hospital, were retrospectively analyzed. Results The male to female ratio was 2.1:1 (255 males and 123 females). The mean age was 6.9 ± 2.3 years. Blunt chest trauma was responsible for chest injuries in 90.5%, while penetrating trauma caused 9.5% of the injuries. Road traffic crashes were the mean cause (48.9%) with pedestrian injuries in 72.4% and passenger injuries in 27.6%, respectively. Sports injuries were the cause in 4% and falls from a height in 22%. Most injuries occurred at home: inside one's own home (5%), outside one's own home (52%); inside someone else's home (44%); outside someone else's home (2%). Public space injuries occurred at schools or creches in 77%, pavement or roads in 6%, and were not specified in 17%. Overall 74% presented with injuries of the thoracic cage; rib fractures occurred in 13%, chest wall contusions in 40%, and abrasions in 31%. Respiratory system injuries occurred in 22%; hemothoraces in 23%, pneumothoraces in 45%, and hemopneumothoraces in 29%. Cardiovascular injuries occurred in 16% of cases with vascular injuries in five patients (two firearms injuries and three motor vehicle crashes). Management was nonoperative in 79.4%, tube thoracotomy in 17.2%, and open surgery in 3.4%. The mortality rate was 1.3%, all contributed by firearm-related injuries and polytrauma. Conclusion Thoracic trauma has remained a significant cause of morbidity and mortality in the pediatric population. Concerted effort from governments, civil societies, and the medical profession are needed to address this challenge.
