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.

The patent ductus arteriosus (PDA) is a common type of congenital heart defect and its correction is simple when performed early in life. Surgery is performed using stitches or clips. In adults, the anomaly can lead to pulmonary hypertension and ventricular dysfunction. Surgery in adults is controversial and high-risk. This report describes an alternative endovascular approach in an adult patient.

Objective: A retrospective study was performed in a series of consecutive patients who underwent a Bentall and De Bono procedure., Methods: Data were removed of medical records and follow-up data were obtained from clinical records and direct contact with patients. A total of 39 patients were studied between January 1996 and December 2005., Results: The median age was 47 years (range 14-70). There were 33 males and six females. Eleven (25.5%) patients presented Marfan syndrome and one (2.5%) Turner syndrome. Nineteen (48.5%) patients had hypertension, eight (20.5%) had history of smoking, six (15.5%) had history of alcoholism, eight (20.5%) had dyslipidemia, two (5.0%) had diabetes and one (2.56%) had myocardial infarct previously. Twenty-eight (72%) patients were in II-III NYHA class in the moment of the surgery. Annulo-aortic ecstasy was present in 14 (35.9%) patients and aortic aneurysms in 16 (41%). The median time in intensive care unit was 8.79 days with range 2-23 days. Four (10.0%) patients underwent an emergency operation and 35 (90%) elective. The overall hospital mortality was 5% (2/39). The event-free survival is 94.87% at 1 year and 84.61% at in 5 and 10. The median time of follow-up was 46.5 months (range 14-120 months)., Conclusion: The Bentall and De Bono technique obtained excellent results in the short-term and long-term, which support the continued use of the compositive graft technique as the preferred method of treatment for patients with aortic root disease. Our findings confirm the current literature data.
