    Acute rheumatic fever is a well-known disease that is still widely observed in developing countries, including our country Morocco. It is known that the majority of patients diagnosed with acute rheumatic fever display abnormalities of the conduction system; However, there are only a few case reports that describe severe impairment in the electrical conduction system. We describe a 21-year-old man who was diagnosed with acute rheumatic fever with complete atrioventricular block. In our patient, the diagnosis of acute rheumatic fever was established. 24-hour electrocardiography showed a paroxistic complete atrioventricular block. Penicillin prophylaxis was made, and salicylate treatment in an anti-inflammatory dose was initiated. The electrocardiographic abnormalities of the patient disappeared. Although rare, this diagnosis should be considered in patients with complete heart block, particularly when it is associated with other features of acute rheumatic fever. Conduction disorders associated with acute rheumatic fever often resolve following appropriate treatment without the need for permanent pacemaker placement

    We present here a rare case of Scimitar syndrome on a full-term newborn female issued from consanguineous marriage and diagnosed at the age of two months who was suffering from polypnea since the age of two weeks. She was admitted at the age of two months for polypnea, non-dysmorphic facies, healthy systemic arterial tension, regular pulse, but the family history raises that before her birth, two newborns respectively boy and girl died both at an early age with dilated cardiomyopathy. After hospitalization, we realized chest radiography, which has shown opaque right lung and suspicion of scimitar syndrome. After that, an echocardiogram was performed, showing severe hypoplasia of the right pulmonary artery with pulmonary hypertension. The Thoracic computed tomography confirmed the diagnosis by revealing hypoplasia of the right pulmonary artery with pulmonary arterial hypertension, right pulmonary hypoplasia (bilobar), and abnormal partial right pulmonary venous return toward the vena cava under the diaphragm

    Atrial fibrillation (AF) is a frequent arrhythmia in patients undergoing hemodialysis (HD). P wave duration (PWdu) and P wave dispersion (PWdi) have been shown to be predictors of emerging AF in different clinical conditions. We sought to study the impact of HD on PWdu, PWdi, and P wave amplitude in a cohort of patients undergoing HD. Seventeen patients (8 men, 31±10 years) were studied. Echocardiography parameters, the sum of the amplitude of P waves in all 12 ECG leads (SP), mean PWdu, and PWdi, along with a host of other parameters (body weight, heart rate, electrolytes and hemoglobin/hematochrit) were measured 1/2h, before and after, HD. SP increased (11.8±3.9 vs 15.3±4.0 mm, p = 0.004), mean PWdu remained stable (82.7±11.1 vs 81.6±10.5 ms, p = 0.606), PWdi decreased (51.7±19.1 vs 41.7±19.1 ms, p = 0.03), and left atrial dimension decreased (37.96±3.90 vs 30.62±3.38 mm, p = 0.0001), after HD. The change in PWdi correlated with fluid removed by HD (r = -0.55, p = 0.022). Re-measurements of P-wave parameters in a random group of 11 of the 17 patients revealed augmented SP (p = 0.01), and stable mean PWdu (p = 0.36), and PWdi (p = 0.31), after HD. Fluid removed by HD leads to an increase in SP, a stable mean PWdu, and decrease (or stability on re-measurement in a subgroup of patients) in PWdi. Stability of PWdu may be due to the effects of augmentation of the P-wave amplitude and the reduction of the left atrial volume, cancelling each other. Variability of PWdi may stem from the occasional impossibility to measure PWdu (or measure it correctly) in minute P-waves in certain ECG leads, which in turn profoundly affects the PWdi

    Viruses represent the main cause, especially in developed countries. Coxsackie and echoviruses are the most common cardiotropic viruses causing myocarditis. Herpes simplex virus-induced myocarditis is uncommon, and few cases of Herpes simplex virus (HSV) type II have been reported to date. This article presents a rare case of subacute herpetic myocarditis in a 35-year-old male patien

    Abstract Background: Isolated cleft mitral valve (ICMV) may occur alone or in association with other congenital heart lesions. The aim of this study was to describe the profile of cardiac lesions associated with ICMV and their potential impact on therapeutic management. Methods: We conducted a descriptive study with data retrieved from the Congenital Heart Disease (CHD) single-center registry of our institution, including patients with ICMV registered between December 2008 and November 2014. Results: Among 2177 patients retrieved from the CHD registry, 22 (1%) had ICMV. Median age at diagnosis was 5 years (6 days to 36 years). Nine patients (40.9%) had Down syndrome. Seventeen patients (77.3%) had associated lesions, including 11 (64.7%) with accessory chordae in the left ventricular outflow tract (LVOT) with no obstruction, 15 (88.2%) had ventricular septal defect (VSD), three had secundum atrial septal defect, and four had patent ductus arteriosus. Thirteen patients (59.1%) required surgical repair. The decision to proceed with surgery was mainly based on the severity of the associated lesion in eight patients (61.5%) and on the severity of the mitral regurgitation in four patients (30.8%). In one patient, surgery was decided based on the severity of both the associated lesion and mitral regurgitation. Conclusion: Our study shows that ICMV is rare and strongly associated with Down syndrome. The most common associated cardiac abnormalities were VSD and accessory chordae in the LVOT. We conclude that cardiac lesions associated with ICMV are of major interest, since in this study patients with cardiac lesions were diagnosed earlier. The decision to operate on these patients must take into account the severity of both mitral regurgitation and associated cardiac lesions

    Abstract Background Owing to challenges associated with heart failure and cardiac embolism, infectious endocarditis emerges as a critical pathology characterized by elevated mortality and morbidity rates. Our case stands out as a rare instance of endocarditis involving multisystem embolization, with a successful outcome. Case presentation We present the case of an 81-year-old man whose admission was further complicated by various septic emboli affecting the brain (manifesting as a brain abscess and ischemic stroke), spleen (resulting in splenic infarction), and spinal cord. The patient received a diagnosis of infective endocarditis affecting the native mitral valve. Following prompt medical and surgical intervention, the overall progression was favorable despite encountering several challenges. Conclusions This case is notable for its detailed description and analysis of the multiple embolic events. More importantly, it underscores the significance of timely surgical intervention and the collaborative approach of a heart team in the face of complicated endocarditis marked by numerous septic emboli. Despite the typically grim prognosis associated with such cases, the outcomes emphasize the positive impact of timely surgery on prognosis

    Abstract Background Carcinoid heart disease is a frequent complication of carcinoid syndrome. It is related to the release by the carcinoid tumor and/or its metastases of bioactive substances such as serotonin. It is characterized by right-sided valvular involvement and can lead to right-sided heart failure. It is a prognostic factor of carcinoid syndrome. Case presentation We report the case of a 53-year-old African woman with an endocrine tumor of her small intestine complicated by carcinoid heart disease, revealed by right-sided heart failure. The diagnosis was confirmed by transthoracic echocardiography, which showed a severe tricuspid regurgitation with a patent foramen ovale, and by increased serum chromogranin A and urinary 5-hydroxyindoleacetic acid. Initially she was treated with medical therapy (furosemide and injection of somatostatin). Afterwards she was proposed for surgery. The evolution of her treatment was good. Conclusions Carcinoid syndrome is complicated in 60% of the cases of a heart disease, and is responsible for an important morbidity and mortality. The prognosis of patients with carcinoid heart disease has improved in recent years through somatostatin analogues and the cardiac surgery

    Abstract Background Coronary artery ectasia is a rare angiographic finding and results from a disease process that compromises the integrity of the vessel wall. Its prevalence ranges between 0.3% and 5% of patients undergoing coronary angiography (Swaye et al. in Circulation 67:134–138, 1983). Coronary artery ectasia in patients with ST-elevation myocardial infarction is associated with an increased risk of cardiovascular events and death after percutaneous coronary intervention. Case presentation We report the case of a 50-year-old male Caucasian patient, admitted for ventricular tachycardia at 200 beats per minute hemodynamically not tolerated that was reduced by external electric shock. Electrocardiogram after cardioversion showed a sinus rhythm with anterior ST-elevation myocardial infarction. Thrombolytic therapy was chosen after exposure to dual antiplatelet therapy and heparin since the expected time to percutaneous coronary intervention was greater than 120 minutes from first medical contact and the patient presented within 12 hours of onset of ischemic symptoms. The electrocardiogram after thrombolysis showed the resolution of the ST segment. The echocardiogram showed a dilated left ventricle with severe dysfunction with left ventricle ejection fraction at 30%. Coronary angiography revealed non-obstructive giant ecstatic coronaries without any thrombus. A check-up to look for possible etiologies for coronary artery ectasia was carried out and returned normal. Since no etiology for coronary artery ectasia was found at the limit of available exams in our center, the patient was discharged with antiplatelet therapy (aspirin 100 mg once a day) and heart failure treatment with an indication for an implantable cardiac defibrillator. Conclusions Coronary artery ectasia in the context of acute myocardial infarction is a rare condition that may have dangerous complications, especially when an optimal treatment for ecstatic culprit vessels is still controversial
