Results of the First 10 Cases of Coronary Bypass Surgery in Senegal

This is a review of the first 10 coronary artery bypass surgeries performed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.

Early Prosthetic Valve Endocarditis with Mycobacterium Tuberculosis after Mitral Valve Replacement: A Case Report

Background: Tuberculous endocarditis is a rare but serious complication of heart valve replacement surgery. We report the case of a 24-year-old patient, who presented with tuberculous endocarditis after mechanical mitral valve replacement, with a favorable clinical course following anti-tuberculosis treatment. Case Presentation: We report a 24-year-old male patient, admitted to the cardiac surgery department of the Fann Hospital (Dakar, Senegal), for the management of severe mixed (rheumatic and endocarditic) mitral insufficiency with associated tricuspid insufficiency. He had a history of recurrent angina and polyarthralgia in childhood, was hospitalized several times for refractory global cardiac decompensation, and for a suspected infective endocarditis a month before his admission. On admission, the clinical examination revealed signs suggestive of mitral and tricuspid insufficiency. Transthoracic echocardiography revealed severe post-endocarditic mitral insufficiency with A3 amputation, highly mobile 15 mm vegetations on the free edge of the large valve, moderate tricuspid insufficiency, and severe pulmonary artery hypertension. Mechanical mitral valve replacement and tricuspid valve annuloplasty using autologous pericardial strip were performed via median sternotomy. After ten days, the patient presented with global cardiac decompensation associated with a clinico-biological infectious syndrome, and tans-oesophageal echography revealed an abscess at the sinotubular junction, communicating with the aorta. A thoraco-abdomino-pelvic CT scan was done, which revealed a bilateral alveolar-interstitial syndrome with mediastinal lymphadenopathy. Anti-tuberculosis treatment with RHZE was initiated for 06 months. The clinical course was favorable. Conclusion: Tuberculous endocarditis in prostheses is a serious complication of heart valve replacement surgery, which may evolve favorably under medical treatment.

Atrioventricular Septal Defect with Intact Interatrial Septum. Case Report

In atrioventricular septal defect (AVSD), anatomical lesions usually are an ostium primum atrio-septal defect;a common atrioventricular valve, an inlet ventricular septal defect (VSD). It is most often associated with major chromosomal abnormalities. It is the most common congenital disease in Down syndrome. Our case was an infant with a Down syndrome who was admitted for a dyspnea (stage 3 in New York Heart Association classification) and tachycardia. The diagnosis was made by a transthoracic echocardiography. It showed a rare variety of atrioventricular septal defect without an atrial septal defect. The child was treated successfully with one patch technic and no recurrence was noted.

Surgical Treatment of Tetralogy of Fallot with Pulmonary Valve Agenesis in a 22 Years Old Patient

Agenesis of pulmonary valve is a rare variant and severe form of Tetralogy of Fallot (ToF). The evolution is usually marked by respiratory and cardiac failure at early age, which needs early surgical correction. Uncorrected treatment of Tetralogy of Fallot diagnosed at adult age is infrequent and only few studies have been described. We present here a rare case of a 22 years old patient who presented with dyspnea since childhood. Subsequent investigations allowed diagnosis of treatment of Tetralogy of Fallot with agenesis of the pulmonary valve. Following the assessment, the patient underwent a surgical repair and the recovery was uneventful. The management of treatment of Tetralogy of Fallot with pulmonary valve agenesis in adult period remains complex, requiring different surgical techniques.

Sclerotherapy for Varicose Veins of the Lower Limbs

Summary: The diagnosis of venous insufficiency is increasing. Multiple techniques are available for its treatment. Chemical sclerotherapy has been performed for over 70 years. The technique improves lately. Objective: This study was conducted to assess early results of foam sclerotherapy in Senegal. Patients and Methods: This is a prospective and descriptive study conducted from January 1st, 2012 to December 31st, 2015 at cardiovascular center of Fann University hospital in Dakar, Senegal. Foam sclerotherapy was done in 76 patients. Polidocanol was used in concentration of 2%. Sclerotherapy was done several times in patients, every week, as much as needed to occlude varicose veins. We used venous compression in all patients. Results: Foam sclerotherapy sessions permitted to get globally good results. In fact, tight feeling and painful leg disappear in 97% of patients. Decreases of edema were gotten in 97% of patients. For leg ulcer, 64% of complete healing was obtained. The main ulcer healing time was 47 days (18;72). Some minor complications occurred. No major events, such as deep venous thrombosis or pulmonary embolism, were observed. Conclusion: Foam sclerotherapy is an efficient technique for the treatment of varicose veins of the limbs. Also, it opens good perspectives for vein care.

Indications and Results of Repair of the Rhumatismal Valve in Children in Senegal concerning 63 Cases

In Africa, acute rheumatic fever is endemic. Cardiac involvement is one of the most common complications in the form of valvular heart disease representing all damages to the heart valves. It is in this perspective that we realized this study whose general objective was to evaluate the results of mitral repair surgery in children in Senegal and the specific objective was to state the indications for mitral repair surgery and assess the results in terms of morbidity and mortality. This is a retrospective and analytical monocentric study, in the thoracic and cardiovascular surgery department of FANN National University Hospital Center in Dakar. It took place over a period of 30 months. All the patients who underwent mitral surgery, aged less than 18 years were included. The total number of patients was 63, including 39 girls and 24 boys, a sex ratio of 0.62. The average age at the time of the surgery was 12 years old [5 - 17]. The functional symptomatology was dominated by the dyspnea found in all the patients. Cardiac ultrasound was diagnosed with mitral regurgitation in all patients. For all surgical procedures, the approach was a vertical midline sternotomy. The mitral valve was approached by left atriotomy in 40 patients (63.5%) and by transseptal way in 23 patients. All patients had undergone mitral valve repair associated or not with either aortic valve repair in 9 patients (14.2%), aortic valve replacement in 3 patients (4.8%), or one tricuspid valve repair in 31 patients (49%). The average duration of intubation was 6 hours [2 - 52]. The average length of stay in intensive care was 2 days. Postoperative complications have been observed. Surgery was performed in 10 patients with 3 mitral valve replacements, 2 aortic valve replacements, a double mitral and an aortic valve replacement associated with a tricuspid repair and in 4 cases a perfection of their mitral repair. Early and late surgical mortality was zero. The average follow-up time for our patients was 9 months [1 - 26]. During their follow-up, the evolution was favorable in 89% of patients who no longer had any functional symptoms.
