Fatou Aw,1 Mouhamadou Bamba Ndiaye,1 Simon Antoine Sarr,1 Malick Bodian,1 Aliou Alassane Ngaide,2 Alassane Mbaye,2,3 Adama Kane,1 Abdoul Kane,4 Maboury Diao,1 Serigne Abdou Ba1 1Department of Cardiology, Aristide Le Dantec Teaching Hospital, 2Department of Cardiology, General Hospital of Grand Yoff, 3Department of Cardiology, Teaching Hospital of Fann, 4Cheikh Anta Diop University of Dakar, Dakar, Senegal Background: The study of the right ventricle (RV) is of particular interest as it is believed to be involved in several heart diseases. Peripartum cardiomyopathy (PPCM) is characterized by left ventricular systolic dysfunction occurring between the last month of pregnancy and the fifth month postpartum. It is often combined with RV dysfunction, but this has rarely been described in the literature. The main aim of this study was to assess the prevalence of RV dysfunction in a PPCM population.Methods: We conducted a prospective and investigative study at the Cardiac Clinic of the Aristide Le Dantec Teaching Hospital in Dakar, Senegal, between March and June 2013. All patients hospitalized during the study period and meeting the diagnostic criteria for PPCM were included.Results: During the study period, 326 patients were hospitalized in the cardiology department; 19 were diagnosed with PPCM corresponding to a hospital prevalence of 5.8%. All patients had left ventricular dysfunction, with an average ejection fraction of 23.01%±9.73% at the Simpson biplane. Based on the tricuspid annular plane systolic excursion (TAPSE), 11 out of the 19 patients (57.9%) had RV systolic dysfunction. Ten patients (52.6%) had an Sa tricuspid wave (speed of the systolic wave to the tricuspid ring in tissue Doppler) below the standard. The average RV area shortening was 23.73%±14.16%, with extremes of 7.8% and 53.7%. Fifteen patients (78.9%) had a rate of shortening fraction of the surface area of RV below the standard. When the other parameters were taken into account, 15 patients (78.9%) had at least 3 of the following indexes altered: fractional area change (FAC), Sa tricuspid, TAPSE, and the ratio between the sum of both isovolumic times and the ejection time (TEI index).Conclusion: RV dysfunction is common in PPCM. In view of the prognostic interest on the right ventricle; its evaluation must take into account all of the measurement parameters in order to allow for better detection.

Abstract

Malick Bodian,1 Fatou Aw,1 Mouhamadou Bamba Ndiaye,1 Adama Kane,1 Modou Jobe,1 Alioune Tabane,1 Alassane Mbaye,2 Simon Antoine Sarr,1 Maboury Diao,1 Moustapha Sarr,1 Serigne Abdou Bâ1 1Department of Cardiology, Aristide Le Dantec Teaching Hospital, 2Grand Yoff General Hospital, Dakar, Senegal Abstract: Routine implantation of pacemakers and implantable cardioverter defibrillators is not commonly associated with complications. However, in some cases we see misplacement of pacemaker leads which is most often related to the presence of underlying cardiac anomalies. We report the case of misplacement of a pacemaker lead into the left ventricle of a 56-year-old patient paced in VVI/R mode and with a tined type pacemaker lead because of a symptomatic complete atrioventricular block. Electrocardiogram showed a pacemaker-generated rhythm with a right bundle branch block pattern. Chest X-ray showed the pacemaker lead located relatively high in relation to the diaphragm. Echocardiography visualized the pacemaker lead in the left heart chambers (atrium and ventricle), hence confirming its aberrant course. Further, the defect causing its passage to the left heart chambers was a sinus venosus atrial septal defect. The patient reported no complication related to the misplacement of the lead. After a brief period of oral anticoagulation, the lead was inserted into the right ventricle by percutaneous technique. Keywords: pacemaker, lead misplacement, sinus venosus atrial septal defect

Abstract

OBJECTIVE: This study aims to explore the risk factors for stone remnants and recurrence after lateral decubitus percutaneous nephrolithotomy (PCNL), providing insights to enhance the stone-free rate and reduce the stone recurrence rate. PATIENTS AND METHODS: A retrospective analysis was conducted on 356 patients with renal or upper ureteral stones who underwent lateral decubitus PCNL from January 2015 to August 2022. Among them, 271 patients had complete clinical and follow-up data. General clinical information, perioperative data, and follow-up data were collected. Univariate and multivariate logistic regression analyses were performed to identify risk factors for stone remnants and recurrence after lateral decubitus PCNL. RESULTS: The stone-free rate after lateral decubitus PCNL was 88.6% (195/271), and the stone recurrence rate within three years was 28.1% (76/271). Stone size (p<0.001) and stone co-infection (p=0.047) were identified as independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones (p=0.003) were an independent risk factor for stone recurrence after lateral decubitus PCNL. CONCLUSIONS: Stone size and stone co-infection are independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones are an independent risk factor for stone recurrence after lateral decubitus PCNL. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: The prevalence of cardiovascular diseases has been rapidly increasing in developing countries, leading to an increasing incidence of acute coronary syndrome which is becoming a major health concern. Few studies have been conducted in hospital settings, which has led us to conduct this cross-sectional, descriptive study in Saint Louis in the north of Senegal, (250 km away from the capital) whose objective is to describe the epidemiological aspects of acute coronary syndrome (ACS) in hospital settings. Methodology: This is a cross-sectional descriptive and retrospective study lasting two years from January 1, 2018 to 31 December 2019 which included all patients hospitalized in the cardiology department of the regional hospital of salary for an ACS. Results: Out of 475 patients admitted to the department of cardiology, 47 presented with acute coronary syndrome which is a prevalence of 9.89%. The mean age was 63+/-13.14 years. There was a male predominance with a sex ratio of 1.5. The meantime between the beginnings of symptoms to hospitalization was 50 hours. The most frequent clinical presentation was acute coronary syndrome with ST segment elevation (STEMI: ST-segment Elevation Myocardial Infarction) in 39 patients. Hypertension was the most common cardiovascular risk factor in 23 patients and chest pain was the most common symptoms 72.3%. In STEMI patients, the ECG abnormalities were mainly in the anterior region and in NSTEMI (Non-ST-segment Elevation Myocardial Infarction) patients the ECG abnormalities were mainly in the inferior region. On echocardiography, 64% of patients had an altered left ventricular ejection function in STEMI patients whereas in NSTEMI patients, the left ventricular ejection function was preserved in 71% of cases. STEMI patients received within the first 12 hours represented 66% of our population of which 84% benefited from thrombolysis with streptokinase with a success rate of 52%. The mean time to thrombolysis was six hours. Six patients or 12.76% were sent for coronarography. The most common complication was cardiovascular collapse (11%), 15% of patients died. Conclusion: The prevalence of acute coronary syndrome is increasing in West Africa with a predominance of ST segment elevation acute coronary syndromes. The main issues encountered were long leading times between onset of symptoms and hospital admission along with limited availability of medical facilities.

Abstract

Introduction: Occlusion of the sinus node artery is a rare situation. It is responsible for sinus node dysfunction and often occurs accidentally during percutaneous coronary intervention of a proximal lesion of the right coronary artery Case Report: This is a sixty-year-old woman with high blood pressure treat by dual therapy (an enzyme conversion inhibitor and a thiazide diuretic), who presented to the cardiological emergency room for a typical angina pain that had been evolving for 48 hours without a lull. Her clinical examination was normal apart from grade 3 arterial hypertension. The 18-lead surface electrocardiogram showed an electrical left ventricular hypertrophy with undershift of the ST segment in lateral and posterior territories, with an overshift of the ST segment in the antero-septal without any sign of necrosis. Biologically, the ultra-sensitive troponinemia was 88 times normal. The diagnosis of NSTEMI with troponin was retained with an intermediate ischaemic risk. Transthoracic Doppler echocardiography showed concentric hypertrophy of the left ventricular walls and dyskinesia of the right ventricle infero-apical wall. The coronary angiography showed an occlusion of the sinus node artery and a left coronary artery atheromatous with an intermediate lesion in the middle segment of the anterior interventricular artery. Conclusion: The present clinical case highlights the diversity in the expression of a sinus node artery occlusion that can occur spontaneously outside of a percutaneous coronary intervention.

Abstract

Introduction: Sudden cardiac death (SCD) remains a major public health issue. In Senegal, there is a lack of data on this phenomenon; this underlies the relevance of this study whose objective is to study the epidemiological profile of victims experiencing unrecovered sudden cardiac arrest at Aristide LE DANTEC Hospital. Patients and Methods: This is a transverse study with retrospective data collection from January 1, 2016 to January 31, 2017. Included, in the study were all victims of sudden cardiac death in Dakar who had a necropsy in the morgues of Aristide Le Dantec Hospital. Results: We recorded 69 cases of sudden death of cardiovascular origin from 169 forensic autopsy reports, or 40.8% of autopsies. The average age was 44 years with a male predominance in 76.81%. The large majority of death occurred at home (26%), without witnesses (48%) and at rest (36%). Two cases of sudden death, or 3%, occurred at exertion. These deaths were recorded in 16% of cases in the middle of the day. The highest death rate was recorded during the month of December (15.9%). Malaise was the predominant symptom (13%) followed by emotional stress (6%). The existence of a history could only be clarified in 4% of cases. The electrocardiogram was only performed in 1 case. At necropsy, ischemic heart disease was the leading disease (46%), 26% of which was due to myocardial infarction, followed by hypertrophic cardiomyopathy (16%) and mixed cardiomyopathy (13%). Tamponade, dilated cardiomyopathy and aortic dissection were found in 9%, 6% and 4% of cases, respectively. Conclusion: Sudden cardiac death is a major public health problem. In the Senegalese population, victims of unrecovered SCD are relatively young with a predominance of men. Coronary artery disease is the most frequently implicated pathology. Faced with this observation, a national program for the integrated control of cardiovascular risk factors is necessary.

Abstract

Objectives: to determine the mechanisms, lesions and hospital management of work-related accidentduringtraditional fishing,an activity subject to vital occupational risks. Materials and methods: Descriptive retrospective study on occupational injury files in artisanal fishing professions, registered at the Saint-Louis Regional Hospital (Senegal), from January 2014 to December 2019. All complete records of trauma during any activity related to artisanal fishingwereincluded. Data on accident mechanisms, injuries observed, and hospital management were collected. Results: 47 male workers were on average 28.4 years old. Direct shock from a pirogue was most frequent (68.10%), followed by sharp or blunt objects (16.27%). The lesions were characterized by bone fractures in 63.83% of cases (n=30); chest-abdominal-pelvic and limb contusions and wounds represented 12.67% and 21.27% of cases, respectively. Medical management was done in 21 cases (44.7%). Surgery was dominated by intramedullary nailing in 15 cases (31.9%). Two laparotomies were performed with intestinal sutures. A chest contusion death was reported. Conclusion: Traumatic occupational risks in traditional fishing are life threatening. A better understanding of these risks and their consequencesmakes it possible to ensure good prevention. [ABSTRACT FROM AUTHOR]
