Right atrial lipoma resection and partial reconstruction using bovine pericardium.

The primary heart tumors have an incidence varying from 0.001% to 0.28% of all tumors, reported in necropsies series. Lipoma consists of a benign tumour corresponding to about 8% of all primary heart tumors. When present, the symptoms are related to the size and location of such tumor. We report a case of a 27-year-old man with a lipoma in the right atrium who underwent surgical treatment with tumor resection and partial reconstruction of the right atrium using bovine pericardium.

Ressecção de um lipoma de átrio direito e reconstrução parcial com pericárdio bovino / Right atrial lipoma resection and partial reconstruction using bovine pericardium

Os tumores primários do coração têm uma incidência variando de 0,001 por cento a 0,28 por cento dentre todos os tumores, relatados em séries de necropsias. Lipoma consiste de um tumor benigno que corresponde a cerca de 8 por cento de todos os tumores cardíacos primários. Os sintomas, quando presentes, estão relacionados ao tamanho e à localização do tumor. Apresentamos o caso de um homem com 27 anos, com um lipoma no átrio direito que foi submetido a tratamento cirúrgico, com ressecção tumoral e reconstrução parcial do átrio direito com pericárdio bovino.

Ressecção de mixoma ventricular esquerdo após acidente vascular cerebral embólico / Resection of left ventricular myxoma after embolic stroke

Mixoma cardíaco é o tumor primário mais comum do coração. Sua principal localização é no átrio esquerdo, mas pode surgir em qualquer câmara cardíaca. Os sintomas clínicos são variáveis, mas dispnéia e embolia são os mais freqüentes. Relatamos o caso de um jovem com acidente vascular cerebral isquêmico embólico causado por um grande mixoma no ventrículo esquerdo. O paciente foi submetido a cirurgia três semanas após o acidente vascular cerebral. O tumor foi ressecado com cuidado, sem fragmentar. O tratamento cirúrgico foi eficaz. Enfatizamos a raridade da presente localização, juntamente com uma revisão da literatura atual.

Cardiac myxoma is the most common primary tumor of the heart. The tumor is located mainly in the left atrium but can arise from any heart chamber. Clinical symptoms are variable but dyspnea and embolism are the most frequent. We report a case of a young man that had embolic ischemic stroke caused by a large left ventricular myxoma. The patient underwent surgery three weeks after the stroke. The tumor was carefully resected without fragmentation. Surgical treatment was effective. We emphasize the rarity of this location together with a review of the current literature.

[The use of the vancomycin paste for sternal hemostasis and mediastinitis prophylaxis]. / O uso da vancomicina em pasta na hemostasia do esterno e profilaxia da mediastinite.

INTRODUCTION: Mediastinitis is one of the most feared complications for thoracic surgeons, being a significant factor in morbidity and mortality in thoracic surgery. OBJECTIVE: To find a new alternative in order to prevent mediastinitis, reducing the morbidity and mortality. METHODS: A retrospective study including 1020 patients operated between February 2002 and October 2005. Patients underwent bypass surgery and vancomycin paste was used rather than bone wax in all cases. RESULTS: Patients were followed-up for 45 months; there were only five (0.49%) cases of mediastinitis; no deaths were observed. CONCLUSION: The use of Vancomycin paste to replace bone wax proved to be a great allied to prevent mediastinitis after thoracic surgery.

O uso da vancomicina em pasta na hemostasia do esterno e profilaxia da mediastinite / The use of the vancomycin paste for sternal hemostasis and mediastinitis prophylaxis

INTRODUÇÃO: A mediastinite é uma das complicações mais temidas pelos cirurgiões cardiovasculares, sendo esta um fator importante na morbidade e mortalidade em cirurgia cardíaca. OBJETIVO: Buscar uma nova opção na prevenção da mediastinite, diminuindo o índice de morbidade e mortalidade. MÉTODOS: Estudo retrospectivo que incluiu 1020 pacientes submetidos a cirurgia cardíaca, no período de fevereiro de 2002 a outubro de 2005. Os pacientes foram submetidos a cirurgia com uso de circulação extracorpórea e implementação da vancomicina em pasta em substituição a cera de osso. RESULTADOS: Os pacientes foram seguidos ao longo de 45 meses, apenas cinco (0,49 por cento) desenvolveram mediastinite e não houve óbito. CONCLUSÃO: O uso de vancomicina em pasta em substituição à cera de osso mostrou-se ser uma aliada na prevenção da mediastinite no pós-operatório de cirurgia cardíaca.

Prospective evaluation comparing the effects of enalapril and losartan in left ventricular remodeling after acute myocardial infarction.

BACKGROUND: Previous studies have compared angiotensin receptor blockers and angiotensin-converting enzyme inhibitors in patients with heart failure, but there are few data about the effect of these drugs regarding left ventricular remodeling after myocardial infarction. METHODS: Fifty-two consecutive patients with first anterior wall myocardial infarction within 24 hours of evolution were randomized to receive enalapril (as much as 20 mg; mean, 14.6 mg), or losartan (as much as 50 mg; mean, 48 mg). Left ventricular ejection fraction and ventricular volumes were analyzed in 2 serial radionuclide ventriculograpies, carried out within 4 days after the infarction (mean, 97.4 +/- 114.2 hours) and after 6 months (mean, 177.7 +/- 16.7 days). Ventriculographies were analyzed by a single blinded observer. Mainly because of the unexpected large SD values obtained, the power of the study to demonstrate equivalence between the groups was only 15.7%. RESULTS: The differences obtained between the first and the second ventriculographies, for the enalapril and losartan groups, were: for left ventricular ejection fraction, -0.4% +/- 6.6% versus -1.1% +/- 5.9% (P =. 67; 95% CI, 2.77-4.23); for final systolic volume, 0.07 +/- 7.7 mL/m(2) versus -0.2 +/- 6.1mL/m(2) (P =. 85; 95% CI, -3.57-4.26); for final diastolic volume -0.7 +/- 12.1 mL/m(2) versus -3.6 - 9.9 mL/m(2) (P =. 34; 95% CI, -3.22-9.17). CONCLUSION: This study, although underpowered, suggests that neither enalapril nor losartan was superior as compared with each other for left ventricular remodeling after myocardial infarction; however, powerful evidence of equivalence was not provided.
