Among 106 patients operated on for implantation of artificial mitral chordae (expanded polytetrafluoroethylene), usually associated with other traditional procedures, 82 had degenerative valve disease. Two of them had the valve replaced during the same operation because of residual regurgitation, and one patient died (1.3%) of respiratory insufficiency.(More)
OBJECTIVES The purpose of this multi-institutional study was to review the 15-year outcome of patients who received isolated aortic or mitral valve replacement with the Hancock II bioprosthesis. METHODS From 1983 through 2002, 1274 patients underwent 1293 isolated valve replacements, 809 aortic valve replacements and 484 mitral valve replacements, at(More)
BACKGROUND The aim of this study was to evaluate the midterm results of a modified button-Bentall operation (modified-bB) specifically designed to incorporate any type of prosthetic valve in composite conduit aortic root replacement. METHODS Between 1991 and 2000, a total of 135 patients underwent modified-bB for annuloaortic ectasia (74 patients), type A(More)
Sixty-seven glutaraldehyde-processed porcine bioprostheses (PBs), recovered at autopsy or reoperation from 65 patients, were evaluated by roentgenologic and pathologic examination. Seven patients with 8 PBs were younger than 20 years of age. The time interval of function was 2 to 138 months (average 62). Pathologically, 53 explants had signs of intrinsic(More)
OBJECTIVE To assess the diagnostic potential of transthoracic and transoesophageal echocardiography for the detection of traumatic cardiovascular injuries in patients suffering from severe blunt chest trauma. DESIGN Prospective study over a three year period. SETTING A regional cardiothoracic centre. PATIENTS 134 consecutive patients (94 M/40 F; mean(More)
The aim of this study was to assess the comparative diagnostic value of transesophageal echocardiography (TEE) and retrograde aortography for morphologic evaluation and anatomic mapping of aortic dissection. Seventy patients (aged 18 to 79 years) were prospectively evaluated with both techniques for suspected aortic dissection. In 64 patients, findings on(More)
From January 1968 to July 1983, 38 patients with an intracardiac myxoma underwent surgical excision of the tumor at our Institution. There were 15 males and 23 females, ranging in age from 17 to 68 years (mean 47.7). In all but 2 patients, the presence of an intracardiac myxoma was documented preoperatively by angiographic and/or echocardiographic study.(More)
The incidence, etiology and risk factors of posttransfusion (PT) hepatitis were evaluated in a prospective study of 297 consecutive open-heart surgery patients. PT hepatitis occurred in 63 (21.2%) patients with a significantly higher hepatitis attack rate in 51 recipients of commercial clotting factor concentrates (56.8%) compared to 246 recipients of blood(More)
UNLABELLED Supraventricular arrhythmias are often observed in patients before and after atrial septal defect repair. Although several papers report different incidences of sustained supraventricular arrhythmias, postoperative 'incisional' macroreentrant tachycardias have not been systematically investigated. METHODS We reviewed 136 consecutive patients(More)
