RÉSUMÉ

Pacemaker infective endocarditis is a more real diagnostic problem than a therapeutic one. The precise impact is not well known. Its incidence is poorly known, and it is a serious infection with an estimated mortality of around 25%. It is with this in mind that we report 2 clinical cases with a literature review. Case 1: An 88-year-old patient with a double chamber pacemaker was admitted for febrile syndrome with a fever at 39.2°. Transthoracic and transesophageal echocardiography (TOE) found an image of vegetation on the aortic valve measuring 9mm, located on the noncoronary cusp, and overflowing on the right coronary cusp. An inflammatory syndrome was found on blood tests. Blood culture, wound swab culture, and bacteriological study of material after removal revealed Staphylococcus Aureus Meti S. The patient was initially put on Vancomycin with a loading dose of 2g / 24h then 1g / 24h, and the pacemaker was extracted. Case 2: A 68-year-old with a double chamber pacemaker (PM) was admitted for fever at 39 ° c with suppuration of the PM pocket. Echocardiography identified an image on the tricuspid valve measuring 14x8 mm evoking vegetation given the context. Two blood cultures and swabs isolated a Staphylococcus aureus. The patient was administered Triaxon 2g / day for 4 weeks and gentamycin 180 mg for 15 days. The pacemaker was removed. Pacemaker Infective endocarditis is rare, poorly understood, very serious, and potentially fatal, accounting for up to about 7% in some case series. In half of the cases, they affect the endocavitary leads, but also the valves, and in 45% of cases the infection of the pocket. The average age is 65 years. The clinical symptoms are disparate making the diagnosis more difficult, it must be evoked in case of unexplained fever in a patient implanted with a Pacemaker. Bactericidal dual therapy should be administered after blood cultures in case of strong suspicion of infective endocarditis (IE) and adapted after identification of the germ in question. Most authors are adamant about extracting any pacemaker whenever possible.

RÉSUMÉ

Aim of the Study: Heart failure is a major problem of public health in Morroco , pulmonary congestion is a key sign which can be easly detected by pulmonary sonography via interlobular septal thickening. The aim of this study was to establish a link Between kerley B lines in the lung and signs of pulmonary congestion. In addition to assess the evolution of these parameters in response to diuretic treatment. Materials and Methods: We prospectively evaluate 118 patients who presented to the emergency of IBN Rochd Hospital in Casablanca with sensation of breathlessness at baseline, 7 days, one month and 3 months for kerley B lines, NYHA Class of dyspnea and the levels of NT pro bnp. the duration of this study was 4 months. Results: Kerley B lines were present in 87.4% of patients initially, 67.6% had elevated levels of NT-probnp and 53%,30%,16% had dyspnea Class II, III and IV respectively. Diuretic treatment have shown a similar improvement of kerley B lines, levels of NT pro bnp and the class of dyspnea . In deed after a follow up of 3 month : only 7 % of patients had persistant kerley b lines, NT pro bnp levels were high in only 7.6% these findings were concordant with the clinical symptomatolgy. Hence only 7% of our patients suffered from dyspnea at moderate efforts at the end of the study. Conclusion: We demonstrated in this study a positive correlation between kerley b lines and levels of NT pro-bnp. These findings may facilitate the orientation of patients within the emergency department and help to initiate heart failure treatment rapidely.
