Introduction: The location of the conduction pathways and their intimate anatomical relationship with the aortic valve provide insight into the occurrence of arrhythmias and conduction disorders during aortic stenosis. These disorders have an important prognostic impact. our work proposes to determine and describe the rhythm and conduction disorders encountered in aortic stenosis in a Moroccan population group while recalling the causes and the prognostic and therapeutic impacts of this association. Materials and methods: This is a retrospective study of 148 patients with aortic stenosis hospitalized at the cardiology center of the HMIMV over a period of 24 months during which we analyzed the clinical and electrocardiographic data in order to describe and analyze the rhythm and conduction disorders encountered in this pathology. Statistical analysis was performed with SPSS software, version 18. Results: The mean age of the population was 65 (57, 74) years, the sex ratio was 1.21 with male predominance. Smoking (current or former) reported in 38.5% of patients was the main modifiable cardiovascular risk factor, followed by hypertension in 35.8% of patients. Dyspnea of effort was the most frequent reason for consultation at 81% of which 64% (of these) were at least of the functional class III of the NYHA. Palpitations and lipothymia or syncope accounted for 21% and 16.2% of the series. The aortic stenosis was tight overall with a mean aortic area of 0.8 [O, 6; 1] cm². Aortic stenosis was rarely isolated. In 36% of cases, it was associated with rhythm and conduction disorders. Among these disorders, atrial fibrillation was the most frequent (36.5%), followed by left anterior hemiblock (17%), LBBB (13.5%) and RBBB (9.5%). Finally there was 9.4% of complete atrioventricular block. Conclusion: The occurrence of arrhythmias and conduction disorders during aortic stenosis is frequent and due to multifactorial mechanism. In the literature, their prevalence is variable ......
Primary pulmonary lymphomas of MALT type (BALT) are rare and their therapeutic management is very heterogeneous but reflects the data of the literature. We report the case of a patient who presented for several months recurrent pneumonia and rebellious to antibiotics. A scano-guided biopsy with anatomo-pathological study allowed making the diagnosis. An immuno-chemotherapy with monoclonal antibodies and single-agent chemotherapy has achieved a good response.
Introduction:The atrial septal defects are the most common congenital heart diseases; moreover the Sinus venous atrial septal defect (SVD) is a rare cardiac abnormality, particularly difficult to diagnose. It is commonly associated anomalous with anomalous pulmonary venous return. The conventional treatment is Surgery. Case report: We report a case of a 61 year old man with medical history only significant for diabetes mellitus. He undergone a chest X rays for his annual medical examination which showed a cardiomegaly; A transthoracic echocardiographies (TTE) examination done previously in other centers showed a dilated right heart chambers with a moderate pulmonary hypertension, but did not show any ASD. He was referred for a dilated right chambers misdiagnosed as a pulmonary hypertension. The TTE revealed a Sinus venosus atrial septal (SVASD) defect seen in the sub costal view. TEE confirmed the diagnosis showing a large SVASD of 20 mm with left-right shunt (Qp/Qs 2, 05). Conclusion: The diagnosis of SVASD is difficult and requires special imaging. But when there is any suspicion of ASD, especially with patients who have unexplained dilated right ventricle and a pulmonary hypertension, the sub-costal view on the TTE can be useful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
