Introduction: Infective endocarditis is defined as infection of a native or prosthetic heart valve, endocardial surface, or cardiac device. The causes and epidemiology, as well as the microbiology of the disease have evolved over the last few decades with the doubling of the average age of patients and an increased prevalence in patients with indwelling cardiac devices. Patients and Methods: This is a retrospective study, including all subjects over 20 years of age who presented with infective endocarditis of the aortic valve, hospitalized between January 2019 and December 2022, in the Department of Cardiology and Vascular Diseases at ERRAZI Hospital-Mohammed VI University Hospital in Marrakech. Clinical, paraclinical and therapeutic data were collected for each case using an exploitation form. Results: Over the study period, 46 patients had presented with aortic positional AR, with a sex ratio that was equal to 1.8. The mean age of the patients was 43±12.5 years. Endocarditis on aortic prosthesis was found in 15%. The valves were rheumatic in 85%. The presumed portal of entry was cutaneous in 45%, oral and ENT in 33%, urinary in 15%, and digestive in 7%. In our series, 21 out of 26 patients presented a biological inflammatory syndrome. At least one or more blood cultures were positive in 38% of cases. Coagulase-negative Staphylococcus was the most common germ in aortic infective endocarditis, found in 40% of positive blood cultures. All the patients in our series had received a combination of broad-spectrum intravenous antibiotic therapy, initially probabilistic, taking into consideration the portal of entry. Adapted after antibiogram results. The evolution during the hospitalization, was marked by an improvement of the clinical state in only 12%, a perioperative death in 38%, and a worsening of the clinical state in 50%, with an average duration of hospitalization of 14 days. In our series, 60% of the patients with positive blood cultures died, whereas there was 75% survival in the group with negative blood cultures. Conclusion: Infective endocarditis is a serious disease because of its high morbidity and mortality. Despite improvements in diagnostic testing, antimicrobial therapy, and surgical intervention, changes in the epidemiology of IE, including the increase in healthcare-associated infections and the virulence of staphylococcus aureus as the causative organism, increase the risk of complications and death in the acute phase of IE. Action must be taken to prevent infective endocarditis, especially in this rheumatically endemic area.
Introduction: Infective Endocarditis (IE) is a serious disease whose prognosis depends on early management. Aortic localization is characterized by its progression to myocardial failure and the high number of complications motivating early recourse to surgery. The diagnosis of AR is based on microbiological and imaging studies. Echocardiography is the recommended imaging modality to make the diagnosis, assess the impact and guide surgery. Materials and Methods: This is a retrospective study, including all subjects over 20 years of age who presented with infective endocarditis of the aortic valve, hospitalized between January 2019 and December 2022, in the Department of Cardiology and Vascular Diseases at the ERRAZI-CHU Mohammed VI Hospital in Marrakech. Clinical, paraclinical and therapeutic data were collected for each case using an exploitation form. Results: During the study period, 26 patients had presented with aortic positional AR, with a sex ratio that was equal to 1.8. The mean age of the patients was 43±12.5 years. A known history of valvular disease was found in 57% of the cases. Among the native valvular diseases, rheumatic origin was found in 85%. The most common valvular lesions were represented by vegetations (88%), which were mobile in 56%, measuring between 10 and 20 mm in half of the cases, their most predominant localization was on the ventricular side with a tilt.IE on severe IAo was found in 90% of cases. The most common associated valvulopathies were MI (53%), RAo (38%) and MR (34%), whose severity was variable. The association of aortic disease with mitral disease was the most frequent association. Echocardiographic complications were presented by fistulas, perforations and peri-aortic abscesses (2 cases each) which were correlated with severe AI. Regarding the impact of the aortic AR on the LV, we noted a marked dilatation in 42% of cases with a preserved ejection fraction in 74%. A quarter of our patients had undergone transesophageal echocardiography in addition to transthoracic echocardiography, with an average time between admission and completion of 3 days. The indication of its realization was posed in front of the doubt of the visualization of an image of vegetations or suspicion of complications not visualized with the TTE. Valvular lesions found on TEE were essentially vegetations in 45% of cases, prolapses in 22% of cases, as well as abscesses, para-prosthetic leaks and prosthesis deinsertion found in 11% of cases. Conclusion: Aortic AR remains a frequent pathology in our context. Aortic insufficiency is the most predisposing valvulopathy and the most common sonographic appearance is vegetations. The results of our study have shown that complications of AE occur preferentially in patients with severe aortic insufficiency.
La maladie d´Ebstein est une malformation congénitale rare dont la présentation clinique diffère selon la forme anatomique et l´âge du patient. Chez l´adulte, elle se présente essentiellement sous forme d´insuffisance cardiaque droite ou globale ou des troubles de rythme. La survie est exceptionnellement longue dans certains cas. La prise en charge varie selon la forme anatomique et la présentation clinique allant de la simple surveillance pour les patients asymptomatiques, à la prise en charge chirurgicale pour les autres cas. Nous rapportons le cas d´un patient ayant une maladie d´Ebstein asymptomatique jusqu´à l´âge de 54 ans où elle est découverte à l´occasion de douleurs thoraciques atypiques, présentation non commune de la maladie. La prise en charge dans ce cas a consisté dans ce cas en une surveillance clinique et échographique stricte.
