Surgical coronary revascularization in patients with COVID‐19; complications and outcomes: A retrospective cohort study

Abstract

Background and Aims Coronary artery disease is high‐risk comorbidity of COVID‐19 infection. Nonelective coronary artery revascularization in COVID‐19 patients carries substantial risk. Therefore, it is essential to understand the risk factors and outcomes fully. This study aims to evaluate the prognosis of coronary artery bypass grafting (CABG) surgery in patients with COVID‐19. Methods This retrospective cohort study assesses 171 patients who underwent urgent and emergent CABG in Tehran Heart Center from March 2020 to September 2021. The patients were allocated to cases and controls based on COVID‐19 infection status. Demographic and clinical features, alongside the complications and outcomes, were compared between the two groups. Results According to diagnostic criteria, 62 patients were diagnosed with COVID‐19 (Case) and 109 patients had no COVID diagnosis (Control). Regarding the demographics and risk factors, hypertension was more prevalent among patients with COVID‐19 (64.5% compared to 43.1% p = 0.007). Length of hospital stay, ventilation time, and intensive care unit (ICU) stay time were significantly higher in patients infected with COVID‐19. Postoperative complications, including stroke, atrial fibrillation, pleural effusion, blood transfusion, and Inotrope use, were significantly higher in the case group. Mortality rates were also higher in COVID‐19 patients with an odds ratio of 1.53; however, this difference is not statistically significant ( p : 0.44, 95% CI = 0.50–4.01). Conclusion COVID‐19 is associated with a significantly higher hospital stay, ventilation time, and ICU stay. Mortality rates are also higher, albeit insignificantly. Various postoperative complications are also higher with COVID‐19.

Evaluation of Risk Factors and Outcomes of Isolated Tricuspid Valve Replacement with a Conventional Surgical Approach: A Retrospective Cohort Study

“…Valve thrombosis is considered the Achilles' heel of mechanical prosthesis in the tricuspid position and is a welldocumented complication by literature [14][15][16]. A metaanalysis reported rates of 1.28% patient/year (range from 0.1 to 4.6% patient/year) [17].…”

Early amiodarone pneumonitis: A case report

“…It is reasonable not to administer antiarrhythmic with similar structure in amiodarone lung injuries such as dronedarone, and a personalized approach for each patient is recommended especially in the elderly patient with underlying lung diseases such as previous severe COVID‐19 which lead to permanent lung injury 11–15 …”

“…10 It is reasonable not to administer antiarrhythmic with similar structure in amiodarone lung injuries such as dronedarone, and a personalized approach for each patient is recommended especially in the elderly patient with underlying lung diseases such as previous severe COVID-19 which lead to permanent lung injury. [11][12][13][14][15] Acute amiodarone-related interstitial pneumonitis is a rare and more aggressive form of the disease, most often occurring in critically ill and post-surgery patients. Acute respiratory distress syndrome (ARDS) and alveolar hemorrhage are the most common pattern of amiodarone pneumonitis, our case also encountered ARDS despite corticosteroid treatment.…”

Double Trouble: Interrupting DAPT and COVID-19

“…It also had a very strong effect on delivery of healthcare for cardiovascular disease, which remains the leading cause of death worldwide. [1][2][3] COVID-19 was associated with a significant and abrupt reduction in cardiovascular diagnostic tests across the globe. At the same time, SARS-CoV-2 infection was associated with a significantly longer hospital stay and ventilation time, higher mortality rates, and various postoperative complications.…”

“…At the same time, SARS-CoV-2 infection was associated with a significantly longer hospital stay and ventilation time, higher mortality rates, and various postoperative complications. 1,4 Cardiovascular disorders have been described as relevant risk factors for severe COVID infection. On the other hand, COVID infection has also been associated with newonset cardiovascular injuries.…”
