Constrictive Pericarditis with Extensive Calcification and Caseous Necrosis.

Constrictive pericarditis is a disease where loss of pericardial elasticity and restriction of filling of the cardiac chambers occurs. It is most often seen as an associated symptom of heart failure. Pericardiectomy provides effective treatment for patients with symptomatic constrictive pericarditis, although high rates of morbidity and mortality are related to the procedure. We present a case with extensive calcification, massive caseous necrosis and an important impairment of right ventricular function successfully operated in our institution.

Abstract Constrictive pericarditis is a disease where loss of pericardial elasticity and restriction of filling of the cardiac chambers occurs. It is most often seen as an associated symptom of heart failure. Pericardiectomy provides effective treatment for patients with symptomatic constrictive pericarditis, although high rates of morbidity and mortality are related to the procedure. We present a case with extensive calcification, massive caseous necrosis and an important impairment of right ventricular function successfully operated in our institution.

Heart Injury with Projectile Lodged Inside the Heart.

Penetrating heart injuries present high mortality rates. Increasing rates of urban violence have contributed to a significant rise in the number of heart injuries by firearm projectiles. Such injuries are associated with the highest mortality rates among penetrating cardiac injuries and may involve one or more cardiac chambers. We present the case of a police officer who, in an approach to five robbers, suffered a transfixed cardiac injury by firearm with the projectile having been lodged inside the right ventricle. This patient was successfully operated, 65 days after the injury, at our institution.

Medida do fluxo intraoperatório com fluxômetro TTFM nos enxertos coronários: resultados de amostra nacional / Intraoperative coronary grafts flow measurement using the TTFM flowmeter: results from a domestic sample

OBJETIVO: Avaliar a perviedade dos enxertos no intraoperatório e identificar enxertos com risco de oclusão precoce. MÉTODOS: Cinquenta e quatro pacientes foram submetidos à revascularização do miocárdio e foi utilizado o fluxômetro (Medtronic Medi-Stim) que utiliza o método de tempo de trânsito (TTFM) para avaliação do fluxo nos enxertos. Três pacientes tinham lesão de tronco de artéria coronária esquerda e 48 apresentavam função ventricular normal ou pouco comprometida. RESULTADOS: A mortalidade hospitalar foi de dois (3,7%) pacientes, um por trombose mesentérica e outro por choque cardiogênico. Dezessete (31,4%) pacientes foram operados sem circulação extracorpórea (CEC). O fluxo no enxerto arterial variou de 8 a 106 ml/min, com média de 31,14 ml/min, e nos enxertos venosos de 9 a 149 ml/min, com média de 50,42 ml/min. CONCLUSÃO: O fluxômetro representa maior segurança para o cirurgião e para o paciente. Até mesmo sob o aspecto legal essa documentação dos enxertos pérvios evitará questionamentos futuros.

OBJECTIVE: To evaluate intraoperative graft patency and identify grafts under risk of early occlusion. METHODS: Fifty four patients were submitted to coronary artery bypass surgery and the graft flow was assessed by the Flowmeter (Medtronic Medistim), which utilizes the TTFM method. Three patients had left main disease and 48 had normal or mildly reduced left ventricular function. RESULTS: In hospital mortality was 3.7% (two patients), one for mesenteric thrombosis and one due to cardiogenic chock. Seventeen patients (34%) were submitted to off pump CABG. Arterial Graft flow measures ranged from 8 to 106 ml/min (average 31.14 ml/min), and venous grafts flow ranged from 9 to 149 ml/min (average 50.42 ml/min). CONCLUSION: Flowmeter use represents higher safety both for patients and surgeons. Even under legal aspects, the documentation provided by the device can avoid future questionings.
