[Follow-up results after left ventricular geometry and volume restoration operations in patients with postinfarctic aneurysm].

UNLABELLED: Fifty patients underwent surgery due to reconstruction of the left ventricular volume and geometry together with heart revascularisation since 1999.02 till 2002.05 of Clinic of Heart Surgery, Vilnius University and Vilnius Heart Surgery Center. Forty eight patients were evaluated in late postoperative period at 3-44 months after the surgery. The functional status of patients improved and the mean NYHA functional class went down from 3.75 till 2.31 (p<0.01). The mean left ventricular ejection fraction significantly raises after operation from 31.8 to 37.8%. Twelve patients in late postoperative period had symptoms of congestive heart failure. These patients had a large asynergy and most intraventricular conductivity disturbances preoperatively. The left ventricular ejection fraction after operation for these patients had no changes and compared with good filling patients they still had larger asynergy. CONCLUSIONS: 1. The functional status of most patients improved after the operation. 2. The left ventricular ejection fraction became better after operation. 3. The stability of good results after 3 years was 65%. 4. Long- term survival after 3 years was 89%.

[Total and partial arterial revascularization].

UNLABELLED: It was shown in a long-term studies that internal thoracic arteries have higher patency, rate compared with saphenous veins grafts. The study was designed to evaluate the late results (1-4 years) of arterial (internal thoracic arteries and radial artery) and venous grafts in a patients referred to coronary revascularization. From April 1997 to June 2002, 405 patients were operated upon using radial artery and internal thoracic arteries and saphenous veins grafts in Vilnius University Heart surgery clinic and Heart Surgery center. One hundred twenty two patients were controlled at 3-36 months. 93% of patients were in CCS f. cl. 0 or 1. Twenty seven symptomatic patients were investigated angiografically at 17,6+/-10 months, and was found patent internal thoracic arteries - 93%, radial artery - 79% and saphenous veins grafts - 62%. CONCLUSION: Arterial grafts tends to be superior than veins grafts in the midterm period.

[Coronary reoperations].

BACKGROUND: We report our experience with 85 patients undergoing a second time CABG in our institution, highlighting surgical techniques and results. METHODS: Eighty five patients underwent a second coronary artery revascularization between 1971 and 2002 at Vilnius University Hospital Santariskiu Clinics. There were 78 men (91.8%); the mean age was 56.5 years (range 40-75). The reason for the second operation was graft failure in 89.4% of the cases. RESULTS: Direct myocardial revascularization was performed in all patient with a mean of 2.4 graft per patient (range 1-4). The internal mammary artery was utilized 17.6%. Hospital mortality was 1.1%. CONCLUSION: Our data suggest that a second - time coronary revascularization can be justified, with gratifying operative success and good results.

[Coronary artery revascularization without cardiopulmonary bypass].

OBJECTIVE: We sought to report our recent experience with off-pump coronary artery revascularization. MATERIAL AND METHODS: Between July 1998 and July 2002, 80 off-pump beating heart operations were performed at Vilnius University Hospital Heart Surgery Clinic, representing 4.05% of all coronary artery revascularization. This cohort of patients was compared with 241 patients operated on with cardiopulmonary by pass. RESULTS: Mean age and preoperative risk factors were comparable for the two groups. On average, 2.02+/-0.86 and 4.09+/-1.09 grafts per patient were completed in the beating and cardiopulmonary bypass groups, respectively. Operation time was shorter in the beating heart group (169+/-41 vs. 215+/-59 minutes). Similarly, the need for transfusion was significantly smaller in the beating heart group (beating heart operations, 10%; cardiopulmonary bypass, 28%; p<0.001). CONCLUSIONS: In majority of patients, off-pump coronary artery revascularization is an acceptable alternative to conventional operations with good results.
