Abstract Background Shockwave Intravascular Lithotripsy® has been recently translated to the treatment of coronary artery disease with a long history of use for ureteric stones where it has been observed to have caused cardiac arrhythmias. The risk of arrhythmia with the use of this method in coronary artery disease is currently unknown. Case summary A 72-year-old man undergoing planned percutaneous intervention to a heavily calcified proximal right coronary artery (RCA) lesion using S-IVL developed pacing capture from the device and subsequently new atrial fibrillation (AF) during the procedure. The technique resulted in successful treatment of the coronary lesion and he spontaneously reverted within an hour of the procedure before discharge. Discussion We postulate the pulsed energy delivered to break apart the calcium has the capacity to cause depolarization, and therefore, affect cardiac rhythm as seen in treatment of renal stones in the past before the introduction of routine electrocardiogram (ECG) gating. In this case, the proximity of the RCA to the right atrium caused short circuiting and development of AF in a susceptible patient. Both the pacing implications and the risk of arrhythmia needs to be investigated further and the potential for ECG gating of the pulsed energy to mitigate this effect needs to be explored to enhance the safety of this technique.

Background: Postoperative atrial fibrillation (PoAF) is observed at a rate of 25-40% in the postoperative period after coronary artery bypass graft (CABG) surgery and can increase mortality, morbidity, and treatment costs. Inflammation and coronary artery disease (CAD) severity are important parameters to predict PoAF. Methods: Patients with right coronary artery (RCA) disease who underwent isolated CABG operation between January 1, 2017 and April 15, 2020, were included in the study retrospectively. Demographic features, preoperative total Gensini score (TGS), right coronary Gensini score (RCGS), systemic immune inflammation index (SII), and postoperative characteristics were recorded. Results: A total of 283 patients were included in the study. Those who did not develop PoAF were included in Group 1 (N = 211, median age=60 (33-82) years), and those who did were included in Group 2 (N = 72, median age=68 (42-85) years). There were no statistically significant differences between the two groups, in terms of gender, hypercholesterolemia, cerebrovascular event/trans-ischemic attack history, body mass index, diabetes mellitus, smoking, beta blocker/angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use, ejection fraction and left atrium diameters. As a result of multivariate analysis, advanced age (OR: 2.816 CI 95%: 1.687-3.498 P < .001), hypertension (OR:0.896, CI 95%: 0.578-0.965, P = .022), SII (OR: 1.548 CI 95%: 1.265-2.896, P = .003), TGS (OR: 1.235, CI 95%: 1.096-2.424, P = .012), and RCGS (OR: 2.112, CI 95%: 1.665-4.156, P < .001) values were determined as independent predictors for predicting postoperative atrial fibrillation. Conclusion: In this study, we showed that RCGS and SII values were independent predictors of PoAF after CABG operations in patients with right coronary artery disease.

Background: Acute coronary syndrome (ACS) is a fatal entity and can be even more deadly if they develops concomitant complications in the form of arrhythmias like atrial fibrillation. Coronary artery disease is thought to be more severe in cases with ACS and atrial fibrillation. Objective: To determine the angiographic findings in patients presenting with acute coronary syndrome and atrial fibrillation and To find the involvement of more common circulation (right or left coronary circulation) leading to atrial fibrillation in acute coronary syndrome. Materials and Methods: This 6 month case series study conducted at department of Cardiology, Sheikh Zayed Hospital, Rahim Yar Khan from14-01-20 to 14-09-20. A total of 198 cases aged 30-60 years of both gender were included in the study through non-probability consecutive sampling. Patients suffering with ACS and has atrial fibrillation on presentation or develops within 24 hours of admission were included. They underwent coronary angiography to look for number of vessels involved, severity of coronary artery disease and culprit vessel involved. Results: In this study there were total 198 cases. Mean age of the participants was 50.09±5.88 years and mean duration of atrial fibrillation was 14.91± 4.51 hours. There were 70 (35.35%) cases with DM, 78 (39.39%) with HTN and 61 (30.81%) smokers. STEMI was found in 35 (17.68%) and NSTEMI in 152 (76.77%) of cases as in figure 05. One vessel disease was observed in 26 (13.13%), two vessel disease in 147 (74.24%) and three vessel disease in 25 (12.63%) of cases. Mild disease on angiography was seen in 45 (22.73%), moderate in 132 (66.67%) and severe in 21 (10.61%) of the cases.it was found that out of 198 patients , 146 ( 74 %) had right coronary artery culprit lesion and 51 ( 26 %) has left sided coronary circulation culprit lesion and from left coronary circulation, left circumflex was most commonly involved : 41 ( 21 % ) of patients as compared to only 10 ( 5 %) patients had culprit in left anterior descending artery. Conclusion: AF in patients with ACS is most commonly associated with right coronary artery lesionsand right type of coronary circulation. In terms of number and severity of disease the most common pattern observed was two vessel disease comprising almost 3/4th of all cases and moderate disease was in most of the vesselsrespectively.

Cad Risk

Background and Objectives: Patients with AF are at increased risk for Coronary Artery Disease (CAD) owing to their shared etiologies and risk factors. This study aimed to assess the prevalence, cardiovascular risk factors, and used medications of CAD in AF patients. Materials and Methods: This retrospective, case-control study utilized data from the Jordanian Atrial Fibrillation (Jo-Fib) registry. Investigators collected clinical features, history of co-existing comorbidities, CHA2DS2-VASc, and HAS BLED scores for all AF patients aged >18 visiting 19 hospitals and 30 outpatient cardiology clinics. A multivariable binary logistic regression was used to asses for factors associated with higher odds of having CAD. Results: Out of 2000 patients with AF, 227 (11.35%) had CAD. Compared to the rest of the sample, those with CAD had significantly higher prevalence of hypertension (82.38%; p < 0.01), hypercholesterolemia (66.52%, p < 0.01), diabetes (56.83%, p < 0.01), and smoking (18.06%, p = 0.04). Patients with AF and CAD had higher use of anticoagulants/antiplatelet agents combination (p < 0.01) compared to the rest of the sample. Females had lower CAD risk than males (OR = 0.35, 95% CI: 0.24–0.50). AF Patients with dyslipidemia (OR = 2.5, 95% CI: 1.8–3.4), smoking (OR = 1.7, 95% CI: 1.1–2.6), higher CHA2DS2-VASc score (OR = 1.5, 95% CI: 1.4–1.7), and asymptomatic AF (OR = 1.9, 95% CI: 1.3–2.6) had higher risk for CAD. Conclusions: Owing to the increased prevalence of CAD in patients with AF, better control of cardiac risk factors is recommended for this special group. Future studies should investigate such interesting relationships to stratify CAD risk in AF patients. We believe that this study adds valuable information regarding the prevalence, epidemiological characteristics, and pharmacotherapy of CAD in patients with AF.
