RESUMEN
Bacterial pericarditis is a critical diagnosis caused by a wide range of organisms including Streptococcus pneumoniae and other anaerobic organisms like Cutibacterium acnes which has been gaining more importance as a causative organism. Cutibacterium species are Gram-positive microaerophilic rods that constitute part of the normal flora of skin and mucosal membranes. The incidence of pericarditis caused by this organism is underreported as it is often dismissed as a skin flora contaminant. However, if left untreated, Cutibacterium acnes can cause pericarditis with serious complications. In this paper, we present a comprehensive review of the literature regarding pericarditis caused by Cutibacterium acnes along with a case presentation from our institution. In our institution, a 20-year-old man with history of atrial septal defect presented with chest pain radiating to the back along with symptoms of upper respiratory tract infection including headaches and myalgia. Electrocardiogram was remarkable for diffuse low-voltage waves. Echocardiography revealed a large pericardial effusion with tamponade features. Pericardiocentesis drained 1.2 L of milky fluid. Pericardial fluid analysis grew Cutibacterium acnes after being cultured for 8 days. The patient received 3 weeks of IV penicillin followed by 3 weeks of oral amoxicillin along with nonsteroidal anti-inflammatory agents and colchicine with no recurrence. Pericarditis caused by Cutibacterium acnes requires a high clinical suspicion since isolation of this organism can be dismissed as a skin flora contaminant. Literature review reveals that this infection may be underdiagnosed and underreported. Prompt diagnosis may lead to timely initiation of antibiotics which can help prevent devastating complications like constrictive pericarditis. Prospective studies are needed to evaluate the true incidence and prevalence of this disease.
RESUMEN
Congenital diaphragmatic hernia (CDH) is a rare type of developmental defect of the diaphragm, occurring in 1 per 2000 pregnancies. Morgagni hernia, in particular, which results from an anterior defect of the diaphragm, is the least common type of CDH (5%). Herniation of the liver into the pericardial space, presenting as a thoracic mass with pericardial effusion, is an extremely rare form of Morgagni hernia. Such reported cases are few and occurred only in singleton pregnancies. To the best of our knowledge, we report the first case of fetal echocardiography and fetal MRI following referral due to large pericardial effusion.

An aortopulmonary window (APW) is a rare congenital heart defect involving an abnormal communication between the ascending aorta and the pulmonary trunk with separate aortic and pulmonary valves. This defect accounts for 0.2% of all congenital cardiac anomalies and if left untreated can lead to Eisenmenger syndrome, severe pulmonary hypertension, heart failure, and poor survival. The authors herein present a case of APW type III with Eisenmenger syndrome in an adult patient whose initial complaint was cyanosis, and provide a thorough review of the literature of cases of APW with Eisenmenger syndrome that have survived into adulthood.

Background: In April 2015, ivabradine was approved by the Food and Drug Administration for the treatment of patients with coronary artery disease and heart failure (HF). The use of this medication has been linked with improved clinical outcomes and reduced rates of hospitalization in patients with symptomatic HF and a baseline heart rate of 70 bpm and above. Nonetheless, little is known about the use of ivabradine in pediatric patients with supraventricular tachycardia (SVT). This use is not well-studied and is only endorsed by a few case reports and case series. Aim: This study discusses the off-label utilization of ivabradine in pediatric patients with SVT, and highlights its efficacy in treating treatment-resistant (refractory) SVT. Methods: We conducted a retrospective single-center observational study involving pediatric patients with SVT treated at our center between January 2016 and October 2020. We identified the total number of patients with SVT, and the number of patients with refractory SVT treated with Ivabradine. Similarly, we performed a thorough review of the databases of PubMed, Medline and Google Scholar to compare the clinical course of our patients to those described in the literature. Results: Between January 2016 and October 2020, 79 pediatric patients with SVT were seen and treated at our center. A treatment-resistant SVT was noted only in three patients (4%). Ivabradine was used in these patients as a single or combined therapy. The rest (96%) were successfully treated with conventional anti-arrhythmics such as ß-blockers, flecainide, and other approved medications. In the ivabradine group, successful reversal to sinus rhythm was achieved in two of the three patients (66%), one patient was treated with a combination therapy of amiodarone and ivabradine, and the other patient was treated only with ivabradine. Conclusion: Overall, promissory results are associated with the use of ivabradine in pediatric patients with refractory SVT. Ivabradine appears to be a safe and well-tolerated medication that can induce adequate suppression of SVT, complete reversal to sinus rhythm, and effective enhancement of left ventricular function.
RESUMEN
Sustained fetal supraventricular tachycardia (SVT) complicated by hydrops fetalis carries a significant risk of morbidity and mortality. While there is no clear consensus on first- and second-line therapy options for the management of fetal SVT with or without hydrops fetalis, there exists significant nonrandomized experience with a number of antiarrhythmic agents that has founded the basis for management. Furthermore, recently published meta-analyses and ongoing multicenter prospective studies have aimed to bridge the gap in the literature. We report two cases of sustained fetal SVT with severe secondary hydrops fetalis managed successfully with flecainide-sotalol combination therapy in one case and sotalol-digoxin combination therapy in the second and review the literature for the management of fetal SVT.

BACKGROUND: The anatomy of the sinus venosus atrial septal defect (ASD) of the inferior vena caval type is complex. Limited rate of complications during its closure has been described. One of the unusual complications, with few case reports, is the iatrogenic diversion of the inferior vena cava (IVC) to the left atrium (LA). CASE SUMMARY: We report the case of a 5-year-old boy who underwent previous surgical closure of sinus venosus ASD of the inferior vena caval type aged 2 years. Three years after surgery, he was diagnosed as having iatrogenic diversion of the IVC to the LA. DISCUSSION: Cardiologists and cardiac surgeons should be aware of this rare but significant complication following routine ASD surgical repair and vigilant follow-up should be performed routinely.
RESUMEN
Congenital depression of the fetal skull is a rare condition. We discuss the case of a 14-days-old male infant, born at term by elective non-complicated caesarean section presenting with a left temporoparietal skull depression. A CT scan was performed which showed no associated fracture. A conservative approach was followed since the infant showed no signs of neurological deficit. Similar cases have been managed successfully in other reports using a conservative approach, with the condition being often self-resolving over the course of a few months.
