Predicting Post-operative Atrial Fibrillation in Cardiac Surgery – The Added Value of Echocardiography
(Scientific Foundation Spiroski (publications), 2021-12-30)
;
;
INTRODUCTION: Post-operative atrial fibrillation (POAF) is a frequent rhythmic complication in cardiac surgery with the potential to cause sudden hemodynamic instability and catastrophic thromboembolic complications. Despite vast scientific research, it is still hard to predict and prevents its occurrence. AIM: The aim of this study was to determine whether selected pre-operative and intraoperative echocardiographic variables would be of added value in POAF prediction. МАTERIAL AND METHODS: This prospective observational follow-up study included 178 cardiac surgery patients undergoing coronary artery bypass graft intervention. Demographic as well as echocardiographic variables of interest were examined to detect significant independent predictors for POAF. RESULTS: POAF was detected in 90 (50.56%) patients versus 88 (49.44%) patients without POAF. Patients who developed POAF were significantly older and burdened with multiple comorbidities. In multiple regression analysis pre-operative echocardiographic variables-diastolic dysfunctions, enlarged left atrial (LA) volume indexed for body surface area, mitral annular calcification, and secondary mitral regurgitation were predictive of POAF. LA appendage flow velocity obtained by intraoperative transesophageal echocardiography was also a significant intraoperative predictor for POAF. CONCLUSION: The results of this study confirmed that two-dimensional echocardiography is a valuable diagnostic and prognostic tool in relation to POAF. The addition of the aforementioned echocardiographic independent predictors to traditional demographic variables could be a solid foundation of a new predictive model for POAF.

A b s t r a c t: Critical limb ischaemia is a result of occlusive arterial disease in the infrainquinal segment and is a major indication for arterial revascularization, which implies a femoropopliteal bypass procedure or an interventional procedure – stent grafting of the occluded segment. Although indications for both techniques are clearly defined, there are still controversies. Thus, the aim of this study was to determine shortterm results in patients treated with these two treatment modalities. In the period between 2002 and 2008 a total of 70 patients with occlusive arterial diseases of the low extremity were analysed. In 50 out of 70 patients a femoropopliteal bypass was made. Of these, in 30 (60%) patients PTFE material was used and in 20 (40%) patients an autologous saphenous vein graft was used. The other group comprised 20 patients who underwent stenting. In patients treated with surgical revascularization, the major indication for surgery was occlusive arterial disease in: stage II – in 10 patients (20%), stage III – in 5 patients (10%), stage IV – in 25 patients (50%) and the remaining 10 patients (20%) had subacute ischaemia. Arteriography showed three crural patent tributaries in 18% of the patients, two patent crural tributaries in 40% of the patients and one crural patent tributary in 32% of the patients. There were no significant differences concerning indications and arteriographic findings between the two subgroups. The follow-up period lasted for 6 months and the patency rate was 85% (17) for venous bypass, 11 (64.6%) – short-segment lesions (< 4 cm) and 6 (35.3%) longer segment lesions (> 4 cm) versus 76.5% (23) for PTFE graft (p < 0.05), of which 13 (56.5%) were short-segment (<4 cm) and 10 (43.5%) longer segment lesions (> 4 cm). 106 Cvetanovski M. V., Jovev S. et al. Contributions, Sec. Biol. Med. Sci., XXX/1 (2009), 105–118 The following results were obtained for the second group of patients: initially successful stents in 85%; failure in 15% or 2 patients; technical failure in 1 patient or 5%. After 6 months the patency rate was 75% (15), of which 11 patients (73.2%) had short-segment occlusions (< 4 cm) whereas 4 patients (26,8%) had lesions > 4 cm. The baseline value of the lower limb index (ABI – ankle-brachial index) was significantly increased in both groups, from 0.41 to 0.91 in the group with surgical revascularization and from 0.47 to 0.88 in the second group treated with stenting. The same trend was observed after six months. This study demonstrated a small but significant difference (85% vs 75%, p < 0.05) in favour of the autologous saphenous vein, which should be a preferred graft material in all cases for reconstruction of the femoropopliteal segment. When compared to the overall patency rate of PTFE grafts after 6 months there was no significant difference in patency in the group treated with stent grafting (76.5% vs 75%). However, stenting is a method of choice in the treatment of short-segment occlusions – smaller than 4 cm with good early run off (73.2% vs 64.6%, p > 0.05 p = ns). It is obvious that the results are identical to those in treatment with an autologous great saphenous vein, but in comparison with PTFE the results imply stent usage (73.2% vs 56.5%, p < 0.005). Prosthesis (PTFE) is a graft material of choice when the great saphenous vein is used, damaged or calcified and when the occlusion is longer than 4 cm and is not suitable for stent grafting (43.5% vs 26.6%, p < 0.001).

Background and Objectives: The role of coronary artery bypass grafting (CABG) on postoperative left ventricular (LV) function in patients with preoperatively preserved left ventricular ejection fraction (LVEF) is still being discussed and only a few studies address this question. This study aimed to assess LV function after CABG in patients with preoperatively preserved LVEF using left ventricular longitudinal strain assessed by 2D speckle tracking imaging (STI). Materials and Methods: Fifty-nine consecutive adult patients with coronary artery disease (CAD) referred for a first-time elective CABG surgery were enrolled in the final analysis of this prospective single-center clinical study. Transthoracic echocardiography (TTE), with conventional measures and STI measures, was performed within 1 week before CABG as well as 4 months after surgery. Patients were divided into groups based on their preoperative global longitudinal strain (GLS) value. Differences in systolic and diastolic parameters between groups were analyzed. Results: Preoperative GLS was reduced (GLS < -17%) in 39% of the patients. Parameters of systolic LV function were significantly reduced in this group of patients compared to the patient group with GLS% ≥ -17%. In both groups, 4 months after CABG there was a decline in LVEF but statistically significant only in the group with GLS% ≥ -17% (p = 0.035). In patients with reduced GLS, there was a statistically significant postoperative improvement (p = 0.004). In patients with preoperative normal GLS, there was not a significant change in any strain parameters after CABG. There was an improvement in diastolic function parameters measured by Tissue Doppler Imaging (TDI) in both groups. Conclusions: There is improvement in LV systolic and diastolic function after CABG in patients with preserved preoperative LVEF measured by STI and TDI. GLS might be more sensitive and effective than LVEF for monitoring improvements in myocardial function after CABG surgery in patients with preserved LVEF.

Infective endocarditis (IE) is a serious complication in patients with transplanted kidney, leading to graft loss and a high mortality rate. We present a case of native valve endocarditis in a 51-year-old male with transplanted kidney that had atypical clinical course. The patient experienced prolonged subfebrile temperature with paroxysmal arrhythmia and development of cardio-pulmonary insufficiency. Transthoracic echocardiography (TTE) set the diagnosis of aortic valve vegetation with severe aortic regurgitation and pulmonary edema. We failed to isolate a microbiological agent, but all blood cultures were taken under antibiotic therapy. The patient was treated with surgical replacement of the native aortic valve with mechanical heart valve with significant clinical improvement. Ten days after the intervention, he was discharged with reduced markers of inflammation and proper function of the kidney graft. Immunosuppressive therapy was gradually reinstated. One year later, the patient was clinically stable and with proper graft function. Early diagnostic and therapeutic intervention, particularly intensive antibiotic therapy and surgical management can preserve the patient and the kidney allograft.

Predictors of atrial fibrillation following coronary artery bypass surgery
(Scientific Foundation SPIROSKI, 2020-07-16)
;
;
;
<jats:p>Atrial fibrillation (AF) is the most common type of arrhythmia following open heart surgery and it contributes to prolonged hospital stay, increased prevalence of thromboembolic complications and overall increased postoperative morbidity and mortality. The aim of this prospective observational follow-up study was to determine the incidence of postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass surgery, to identify predisposing risk factors for its occurrence in the immediate preoperative period and to assess its effect on the postoperative outcome in patients at the University Clinic for Cardiac Surgery in Skopje, North Macedonia. Material and methods: The study included patients at the University Clinic for Cardiac Surgery in Skopje, North Macedonia undergoing coronary artery bypass surgery. The experimental group included patients developing POAF, whereas the control group those who did not develop the primary outcome. All patients were followed up for a period of 30 days postoperatively. Results: POAF was registered in 38% of the patient population and more frequently in the elderly. Patients developing POAF had significantly higher left atrial volume index, as well as higher CHADS2-VASC2, HATCH and Euroscore I values. Average time to POAF occurrence was 48-72 hours postoperatively. There were death outcomes, thromboembolic events, longer hospital stay, need for antiarrhythmic and oral anticoagulant therapy in the POAF group. Conclusion: POAF significantly increases postoperative morbidity and mortality in patients undergoing coronary artery bypass surgery. Age, higher CHADS2-VASC2, HATCH and Euroscore I values and left atrial volume were found to be significant predictors of POAF after coronary artery bypass surgery.</jats:p>
