The Impact

Atrial fibrillation is the most common type of arrhythmia with increasing burden for stroke and thromboembolic events. Medical treatment of atrial fibrillation has not shown promising results, so alternative method of treatment is emerging out. Cox-Maze procedure has been used for decades for the treatment of atrial fibrillation. Surgical treatment of atrial fibrillation with traditional Cox-Maze procedure is a complex and technically challenging procedure limiting its use in clinical practice. Recently, radiofrequency ablation is being used as a modification of Cox-Maze procedure. However, its effect in the treatment of atrial fibrillation in not reported uniformly and in large number of patients. Therefore, our aim of study was to assess the impact of concomitant radiofrequency ablation in the treatment of atrial fibrillation during cardiac surgery. We performed literature review on PubMed Central to evaluate effect of concomitant radiofrequency ablation for atrial fibrillation treatment. About 303 papers were found using the reported search, of which 15 represented suitable to fulfill our query. The authors, date, patient group, study type, relevant outcomes and results of these papers are tabulated. We conclude that radiofrequency ablation surgery of left atrium at the time of other cardiac procedures is a comparatively straightforward procedure with satisfactory freedom from atrial fibrillation, acceptable morbidity, mortality, and minor procedure related complications. Careful patients selection by sticking to the - Rule of 5, i.e. left atrial diameter less than 55 mm and atrial fibrillation duration no more than five years, is recommended to optimize the result of atrial fibrillation surgery.

The Impact

The short-term impact of atrial fibrillation (AF) on cardiac surgery hospitalizations has been previously reported in cohorts of various sizes, but results have been variable. Using the 2005–2014 National Inpatient Sample, we identified all adult hospitalizations for cardiac surgery using the International Classification of Diseases, Ninth Revision, Clinical Modification as any procedure code and AF as any diagnosis code. We estimated the impact of AF on inpatient mortality, length of stay (LOS), and cost of hospitalization using survey-weighted, multivariable logistic, accelerated failure-time log-normal, and log-transformed linear regressions, respectively. Additionally, we exact-matched AF to non-AF hospitalizations on various confounders for the same outcomes. A total of 1,269,414 hospitalizations were noted for cardiac surgery during the study period. Coexistent AF was found in 44.9% of these hospitalizations. Overall mean age was 65.6 years, 40.9% were female, mean LOS was 11.6 days, and inpatient mortality was 4.5%. Stroke rate was lower in AF hospitalizations (1.8% vs 2.1%, p<0.001). Mortality was lower in the AF (3.9%) versus the non-AF (5%) group (exact-matched OR or emOR=0.48, 95% CI 0.29 to 0.80, p<0.001; 987 matched pairs, n=2423), with similar results after procedural stratification: isolated valve replacement/repair (emOR=0.38, p<0.001), isolated coronary artery bypass graft (CABG) (emOR=0.33, p<0.001), and CABG with valve replacement/repair (emOR=0.55, p<0.001). A 12% increase was seen in LOS in the AF subgroup (exact-matched time ratio=1.12, 95% CI 1.10 to 1.14, p<0.001) among hospitalizations which underwent valve replacement/repair with or without CABG. Hospitalizations for cardiac surgery which had coexistent AF were found to have lower inpatient mortality risk and stroke prevalence but higher LOS and hospitalization costs compared with hospitalizations without AF.

Reducing mortality due to cardiovascular complications (CVC) after non-cardiac surgery is one of the priority tasks of modern healthcare. According to the literature data, it is the CVC that are leading cause of perioperative mortality in non-cardiac surgery. Atrial fibrillation (AF) is a common complication after surgery. It is believed that in most cases the AF is potentiated by a combination of factors. It is intraoperative triggers, such as deliberate hypotension, anemia, injury, and pain, that can directly contribute to development of arrhythmia. However, heart rate monitoring after non-cardiac surgery is performed in only a small number of patients, so in most cases, arrhythmias remain unreported. The Revised Cardiac Risk Index (RCRI) and theAmericanCollegeof Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Surgical Risk Calculator are the current tools for assessing perioperative cardiovascular risk. Postoperative AF is not included in any CVC risk stratification system. The presented review systematizes the data that postoperative AF is closely associated with perioperative complications and in some cases it may be the only marker of these complications.  It has been shown that AF detection is of great clinical importance in both high-risk patients and, especially, in patients with a low risk of potential complications in non-cardiac surgery.

Background. Atrial fibrillation surgical radiofrequency ablation (AFSA) during mitral valve surgery (MVS) has almost completely superseded the Cox-Maze procedure for the treatment of atrial fibrillation. Methods. We retrospectively analyzed 100 patients who underwent MVS + AFSA in our institution from January 2008 to June 2017. We compared the effectiveness of AFSA in patients who underwent LAA exclusion to those who did not. Moreover, we analyzed the role of preoperative AF duration (≤ or >1 year) and medial-lateral left atrial dimensions (ML-LAD) (≤ or >6 cm). The efficacy endpoint was freedom from AF at discharge and at 2-year follow-up. The safety endpoints were need of a permanent pacemaker (PMK), surgical re-exploration, occurrence of stroke, and left circumflex artery or esophageal lesions. Results. Overall, the rate of AF freedom was 69% at discharge and 80% at 2-year follow-up. LAA exclusion did not influence AF freedom at 2-year follow-up, and 84.6% of patients who underwent LAA exclusion were in the sinus rythm (SR) at 2 year compared to 75% of those who did not receive LAA exclusion free from AF as well ( p = 0.230 ). AF duration ≤1 or >1 year did not influence sinus rhythm (SR) maintenance (85.7% vs. 75.8%; p = 0.224 ), and in these two groups, LAA exclusion did not change the efficacy of AFSA. ML-LAD ≤ 6 cm was associated with better results in terms of SR maintenance. A statistically significant association between LAA exclusion and SR maintenance at 2-year follow-up ( p = 0.017 ) was found among patients with ML-LAD ≤ 6 cm. Complications included 7 cases of PMK implantation, 2 cases of surgical re-exploration, and 1 case of stroke. No circumflex artery or esophageal lesions occurred after surgical procedures. Conclusions. In our experience, AFSA during isolated MVS resulted in good outcomes in terms of SR maintenance and incidence of complications. AF duration ≤ 1 year did not influence results, while patients with ML-LAD ≤ 6 cm had significantly better results regarding SR at follow-up. In patients with ML-LAD ≤ 6 cm, LAA exclusion significantly increased the success rate of SR maintenance at 2-year follow-up.

Background: The Maze procedure is the surgical treatment that can alleviate the three complications of atrial fibrillation- tachycardia, thrombo-embolism and hemodynamic compromise. We attempted ablation of atrial fibrillation with monopolar eletrocautery.Our objective was to evaluate the results of surgical treatment of atrial fibrillation by ablation of the left atrial wallaround the pulmonary veins with conventional electrocautery during mitral valve replacement.Methods:This retrospective observational study was carried out in the Department of Cardiac Surgery, National Institute of cardiovascular diseases, Dhaka, Bangladesh,from January 2014 to February 2016. Ablation of AF with monopolar electrocautery was done during mitral valve replacement. Recurrence of atrial fibrillation, any new arrhythmia, complete heart block, bleeding and perforation was noted during the operation and in postoperative period. Patients were followed up upto three months after the surgery.Results: All the Patients were free from atrial fibrillation after the procedure. At discharge 100 %, after I month 96.2% and after 3 months 92.3 % patient were free from atrial fibrillation. No patients developed complete heart block requiring pace maker and there was no incidence of atrial perforation at the sites of ablation.Conclusion: The surgical treatment of the atrial fibrillation with elcetrocautery during mitral valve replacement is able to reverse this arrhythmia in a significant number of patients during short term follow-up without any complication.Cardiovasc. j. 2016; 9(1): 9-12

Long Term Mortality

Introduction Atrial fibrillation (AF) is frequent after any cardiac surgery, but evidence suggests it may have no significant impact on survival if sinus rhythm (SR) is effectively restored early after the onset of the arrhythmia. In contrast, management of preoperative AF is often overlooked during or after cardiac surgery despite several proposed protocols. This study sought to evaluate the impact of preoperative AF on mortality in patients undergoing isolated surgical aortic valve replacement (AVR). Methods We performed a retrospective, single-centre study involving 2,628 consecutive patients undergoing elective, primary isolated surgical AVR from 2008 to 2018. A total of 268/ 2,628 patients (10.1%) exhibited AF before surgery. The effect of preoperative AF on mortality was evaluated with univariate and multivariate analyses. Results Short-term mortality was 0.8% and was not different between preoperative AF and SR cohorts. Preoperative AF was highly predictive of long-term mortality (median follow-up of 4 years [Q1-Q3 2-7]; HR: 2.24, 95% CI: 1.79-2.79, P<0.001), and remained strongly and independently predictive after adjustment for other risk factors (HR: 1.54, 95% CI: 1.21-1.96, P<0.001) compared with preoperative SR. In propensity score-matched analysis, the adjusted mortality risk was higher in the AF cohort (OR: 1.47, 95% CI: 1.04-1.99, P=0.03) compared with the SR cohort. Conclusions Preoperative AF was independently predictive of long-term mortality in patients undergoing isolated surgical AVR. It remains to be seen whether concomitant surgery or other preoperative measures to correct AF may impact long-term survival.
