ABSTRACT

BACKGROUND: Myxoma is the most common cardiac tumor, found in 75-80% of cases in the left atrium. It can grow quietly and therefore reach a large size before being symptomatic. Poor availability of echocardiography also contributes to delayed diagnosis. In Sub-Saharan African countries, myxoma diagnosis can be missed for many patients. Myxoma resection surgery, although technically simple, is not always possible, because of the lack of cardiac surgery development. The aim of this report is to describe the first two consecutive resection cases of huge left-atrial myxoma performed in Kinshasa, Democratic Republic of Congo (DRC) and to discuss the specificities of this surgery in this low-resource context. CASE PRESENTATION: Two patients, 54 and 48 years old, were diagnosed with giant myxoma of the left atrium in the management of progressive dyspnea The first patient's transthoracic echocardiography revealed a pedunculated atrial mass (37 × 48 mm) on the interatrial septum, passing through the mitral valve. For the second patient, the mass (64 × 26 mm) was attached to the roof of the left atrium and protruded into the mitral valve, with significant mitro-tricuspid regurgitation The first patient underwent a simple resection of the myxoma. For the second patient, it was associated to a mitro-tricuspid annuloplasty. The postoperative course was simple for the first patient, but the second patient developed a biventricular failure requiring vasoactive drugs. Both patients were discharged alive from the hospital on postoperative days 10 and 12, respectively. They are regularly followed up and are doing well 2 years after surgery. DISCUSSION AND CONCLUSION: Surgical resection is the only effective treatment of myxoma. Our first results are encouraging The poor availability of the echocardiography is a challenge in the diagnosis of myxoma. The development of cardiac surgery in DRC and ongoing country-level efforts to address diagnostic challenges for these often silent tumors will allow us to expect more resections to be performed locally and larger series published.

ABSTRACT

Isolated aneurysm of the internal iliac artery is rare. To the best of our knowledge, we report the first documented case of conventional surgical treatment of a ruptured internal iliac artery aneurysm in the Democratic Republic of the Congo.

ABSTRACT

Contexte et objectif. Dans le cadre des 3 missions organisées par l?association des anciens de la faculté de médecine de l?université de Kinshasa, en République Démocratique du Congo, nous avons opéré des enfants porteurs d?une persistance du canal artériel (CA). Les objectifs de cet article étaient de rapporter notre première expérience de la chirurgie cardiaque pédiatrique dans notre pays, et d?évaluer nos résultats sur la qualité de la prise en charge pré-, per- et post-anesthésique de ces premiers patients opérés par nos soins.Méthodes. Il s?agit d?une étude documentaire descriptive type série de cas. Tous les patients opérés pour persistance du canal artériel aux cliniques universitaires de Kinshasa de novembre 2013 à novembre 2014 ont été inclus. Le protocole d'anesthésie était le même pour tous les patient. Les données pré-, per- et post-anesthésiques, ainsi que les résultats chirurgicaux obtenus ont été recueillies de façon prospective.Les critères utilisés pour évaluer la qualité de l'anesthésie étaient ceux proposés par la société française d?anesthésie-réanimation. La saisie et l?analyse des données ont été réalisées à l?aide du logiciel Excel. Les variables quantitatives sont décrites en moyenne et valeurs extrêmes et celles qualitatives en fréquence et pourcentage.Résultats. Au total, dix enfants ont été opérés. L?âge moyen était de 54 mois (extrêmes : 8 mois ­ 16 ans). Leur traitement médical pré-op comprenait essentiellement les IEC (5cas), les diurétiques (2 cas) et les digitaliques (2 cas). Les facteurs de risque préopératoires retrouvés dans notre série étaient la dénutrition (1 cas) et l?anémie (2 cas).Le geste chirurgical a consisté à une ligature (8 cas) ou à une section (2 cas) du CA, par une thoracotomie postérieure gauche. La durée moyenne d?intervention a été de 78 min (extrêmes 65 et 120 min). Les paramètres hémodynamiques et respiratoires peropératoires de nos patients sont restés stables durant la totalité du temps chirurgical à l?exception d?une patiente qui a présenté un saignement abondant (500 ml) suite à un déclampage intempestif sur un des moignons du canal artériel. Pour tous les autres patients, le saignement peropératoire a été minime, voire absent. Dans 9 cas sur 10, l?extubation était réalisée en fin d?intervention.En post-opératoire, l?analgésie était satisfaisante avec des scores d?EVS inférieur à 2 chez 8 patients. La première boisson était possible dans un délai moyen de 6 h sans fausse route, sans nausée ni vomissements. Trois cas d?infection superficielle de site opératoire ont été relevés et traitées avec succès par des soins locaux. La durée moyenne de séjour en réanimation était de 3,85 jours (extrêmes : 2 et 8 j) et la durée totale d?hospitalisation de 7,6 jours (extrêmes : 7 et 13 j). Aucun décès n?a été déploré.Conclusion. Cette étude démontre la faisabilité de l'anesthésie pour fermeture du CA dans notre pays avec une bonne qualité d?anesthésie et de bons résultats chirurgicaux. Avec plus de moyens à notre disposition, nous pourrons étendre notre activité à toute la chirurgie cardiaque adulte et pédiatrique sous circulation extracorporelle. C?est cela notre but ultime

ABSTRACT

OBJECTIVES: The St Jude Medical Trifecta bioprosthesis incorporates a single pericardial sheet externally mounted on a titanium stent that provides excellent haemodynamic results. The purpose of this multicentre study was to report on the haemodynamic performance and the expected lower risk of prosthesis-patient mismatch in patient with small aortic annulus diameters. METHODS: The 19- and 21-mm Trifecta valves were implanted in 88 and 266 eligible patients, respectively between 2011 and 2013 at three centres in France (Angers, Rennes and Amiens). The mean age of the population was 78 ± 7 and 76 ± 6 years for 19- and 21-mm valve sizes of which 96.6 and 68% were female, respectively. The aortic valve replacement was associated with another surgery in 18.2 and 21.8% in each group, respectively. RESULTS: The mean follow-up was 20.3 ± 11.9 and 24 ± 11.4 months for 19- and 21-mm valves, respectively. Early all-cause mortality was 2.5% and late mortality occurred in 5.8% of patients. The mean pressure gradient and the effective orifice area at discharge and at 1 year were respectively 12.4 ± 4.6 and 14.7 ± 5.8 mmHg (P = 0.003), 1.5 ± 0.3 and 1.4 ± 0.9 cm(2) (P = 0.06) in the 19-mm valve group; 10.4 ± 3.8 and 11.7 ± 4.5 mmHg (P = 0.001), 1.8 ± 0.3 and 1.5 ± 0.4 cm(2) (P = 0.1) in the 21-mm valve group. At 1 year, only 38 (11%) and 28 (8.1%) patients presented a moderate or severe prosthesis-patient mismatch for the two groups. After univariate analysis, no risk factor of mismatch was found. CONCLUSIONS: The 19- and 21-mm St Jude Medical Trifecta provide excellent haemodynamic performance and the rate of moderate and severe prosthesis-patient mismatch is low.

ABSTRACT

The authors propose a new strategy of normothermic perfusion for replacement of the aortic arch to avoid the complications of profound hypothermic circulatory arrest. Six patients underwent complete replacement of the aortic arch under normothermia using two pumps for the body (one for the brain and the thoracoabdominal aortic branches) and one for the heart. The surgical procedure was performed with no time limit. There were no operative or late deaths. No patients had neurologic deficit and all were rapidly extubated with uneventful postoperative courses. The method preserves autoregulation of cerebral blood flow and maintains body perfusion without high vascular resistances.

ABSTRACT

A case of purulent pericarditis with an unusual aetiology and a favourable outcome is reported. This patient presented with purulent pericarditis secondary to an oesophago-pericardial fistula caused by a squamous carcinoma of the oesophagus. A review of the literature revealed only a small number of similar cases. The prognosis can be improved by rapid diagnosis, appropriate antibiotic therapy, surgical drainage and surgical repair of the fistula. An aggressive therapeutic approach should be proposed in order to achieve long-term remission in these frequently young patients.
