RESUMEN
Electrocautery has a potential risk of serious pacemaker dysfunction in patients with implanted pacemaker. Here we present the safe and efficient use of ultrasonic scalpel (Harmonic scalpel) for the first time in a patient with implanted pacemaker undergoing open-heart reoperation.

BACKGROUND AND AIM OF STUDY: Mitral valve repair is the standard reparative technique for degenerative mitral disease, but results of valve repair in rheumatic disease are also encouraging. The outcomes after mitral valve repair for rheumatic disease at young age was evaluated for suitability of repair. METHODS: A total of 319 patients (246 females, 73 males; mean age 31.3+/-0.5 years) underwent mitral valve repair for rheumatic mitral disease at the authors' institution between 1991 and 1998. Mean follow up was 51.9+/-1.2 months (range: 9-98 months), and was 88.7% complete. RESULTS: Preoperatively, 47.6% of patients were in NYHA classes III and IV. Mitral stenosis was present in 87.5%, insufficiency in 5.3%, and stenosis/insufficiency in 7.2%. Concomitant procedures were performed in 32% of patients who had associated cardiac lesions. The intraoperative mortality, reoperation and reoperation mortality rates were 0.9%, 6.7% and 0%, respectively. During follow up there were 10 late deaths (3.5%), six of which were cardiac disease-related (2.1%). Postoperatively, 98% of patients were in NYHA classes I and II. CONCLUSION: Valve repair in mitral disease is a standard technique, with low mortality, complication and reoperation rates, and good cardiac function and late survival. This approach is equally applicable to rheumatic mitral valve repair; hence, rheumatic mitral valves should also be repaired.

BACKGROUND AND AIM OF THE STUDY: Despite having been used in many thousands of implants, few published data exist concerning the ATS valve. Clinical data from ATS valve implants are presented, and the first two cases of mitral valve thrombosis with the ATS valve reported. Published data are also reviewed comparatively. METHODS: Between September 1998 and July 2000, 240 ATS valve prostheses were implanted in 199 patients, of whom 88 (36.6%) had mitral (MVR), 70 (29.1%) aortic (AVR), and 41 (17.1%) double valve replacements (DVR). Additional procedures were performed in 31 patients (15.6%). Transvalvular gradients and effective orifice areas were measured by transthoracic echocardiography. Total cumulative follow up of all patients was 241.6 patient-years (pt-yr); mean (+/-SE) follow up was 1.25+/-0.51 years. RESULTS: There were six early deaths (3.0%). Overall and event-free survival rates during follow up were 98.96+/-0.73% and 97.90+/-1.22%, respectively. Anticoagulant-related hemorrhage occurred in one patient. The global incidence of hemorrhagic complications was 0.41 per 100 pt-yr. One patient with AVR was reoperated on for periprosthetic leakage in the first postoperative week. Valve thrombosis occurred in two patients with MVR at 12 and 14 months postoperatively. The incidence of valve thrombosis in MVR patients was 1.84 per 100 pt-yr (0.82 per 100 pt-yr overall). Hemolysis was seen only in one patient, echocardiographic examination revealing periprosthetic leakage. CONCLUSION: The short-term outcome in 240 implants showed the ATS valve to be safe, to have a low incidence of complications, and to provide excellent hemodynamic performance.

OBJECTIVES: to retrospectively evaluate the role of vascular interventions in Behçet's disease with arterial involvement. So far, little information is available on the surgical approach for arterial involvement in Behçet's disease. MATERIAL AND METHODS: between February 1989 and August 1997, among 178 patients with Behçet's disease referred to our clinic, vascular involvement was established in total of 67 patients (38%) which consisted of 59 venous (33%) and 12 (7%) arterial involvements requiring urgent surgical intervention. Primary arterial lesions were occlusive in one patient, aneurysm formation in nine or both in four. RESULTS: twelve primary operations and 12 reoperations were performed. The reasons for reoperations were anastomotic aneurysms, graft occlusion, occlusion of native vessel, graft infection, bleeding from anastomosis and aortoenteric fistula. First reoperation was performed after a mean period of 6.4 months (1-15 months). Postoperative follow-up was 12-60 months (mean 36 months) and three patients died during follow-up. CONCLUSIONS: the surgical results were not satisfactory because of progressive graft thrombosis and formation of new aneurysms at the anastomosis. Aggressive medical treatment should be combined when major vessel involvement occurs. All types of arterial punctures for angiography or blood gases should be minimised because of the risk of new aneurysm formation. Surgical intervention is indicated only in patients with a growing aneurysm, acute rupture or severe ischaemia.
