The Clinical Significance of Unplanned Coronary Artery Bypass Grafting in Aortic Root Replacement.

OBJECTIVES: Unexpected coronary artery bypass grafting (CABG) is occasionally required during aortic root replacement (ARR). However, the impact of unplanned CABG remains unknown. DESIGN: A single-center, retrospective observational study. SETTING: At university-affiliated tertiary hospital. PARTICIPANTS: All patients who underwent ARR from 2011 through 2022. INTERVENTIONS: Aortic root replacement with or without unplanned CABG. MEASUREMENTS AND MAIN RESULTS: A total of 795 patients underwent ARR. Among them, 131 (16.5%) underwent planned concomitant CABG, and 34 (4.3%) required unplanned CABG. The most common indication of unplanned CABG was ventricular dysfunction (33.3%), followed by disease pathology (25.6%), anatomy (15.4%), and surgical complications (10.3%). A vein graft to the right coronary artery was the most commonly performed bypass. Infective endocarditis and aortic dissection were observed in 27.8% and 12.8%, respectively. Prior cardiac surgery was seen in 40.3%. The median follow-up period was 4.3 years. Unplanned CABG was not associated with operative mortality (odds ratio [OR] 1.54, 95% CI 0.33-7.16, p = 0.58) or long-term mortality (hazard ratio 0.91, 95% CI 0.44-1.89, p = 0.81). Body surface area smaller than 1.7 was independently associated with an increased risk of unplanned CABG (OR 4.51, 95% CI 1.85-11.0, p < 0.001). CONCLUSIONS: Unplanned CABG occurred in 4.3% of patients during ARR, but was not associated with operative mortality or long-term mortality. A small body surface area was a factor associated with unplanned CABG.

Pulmonary Hypertension in 2021: Part I-Definition, Classification, Pathophysiology, and Presentation.

The World Symposium on Pulmonary Hypertension (WSPH) was organized by the World Health Organization in 1973 in response to an increase in pulmonary arterial hypertension in Europe caused by aminorex, an appetite suppressant. The mandate of this meeting was to review the latest clinical and scientific research and to formulate recommendations to improve the diagnosis and management of pulmonary hypertension (PH).1 Since 1998, the WSPH has met every five years and in 2018, the sixth annual WSPH revised the hemodynamic definition of PH. This two-part series will review the updated definition, classification, pathophysiology, presentation, diagnosis, management, and perioperative management of patients with PH. In the first part of this series, the definition, classification, pathophysiology, and presentation will be reviewed.

Basic Transesophageal Echocardiography Education for Senior Anesthesiology Residents-Institutional Experience.

OBJECTIVE: The use of basic transesophageal echocardiography (TEE) in critically ill and older surgical patients can change patient management and improve outcomes after noncardiac surgery. The authors hypothesized that educating the future generation on basic TEE skills by an intense two-month rotation will help them achieve basic TEE certification by the National Board of Echocardiography (NBE) and facilitate good use of their skills for patient care during their practice. DESIGN: This is a descriptive report of graduating anesthesiology residents who completed two months basic TEE rotation at the authors' residency program between 2013 and 2019. The authors report the clinical training goals, NBE testamur and certification status, and a survey report on the use of basic TEE skills in their practice SETTINGS: University medical center. PARTICIPANTS: Residents who completed two months basic TEE rotation during their Clinical Anesthesia (CA)-3 year. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of a total of 115 residents, 67 (58%) elected basic TEE rotation. The NBE basic TEE certification and testamur status were achieved by 12 (21%) and 14 (24%) eligible residents, respectively. Residents (n = 43) personally performed 73 ± 21 (mean ± standard deviation) and reviewed 72 ± 28 (mean ± standard deviation basic TEE studies before graduation. The survey indicated that 63.4% of residents trained in basic TEE did not use their skills in their practice. CONCLUSIONS: Two months' basic TEE rotation was able to fulfill its educational goals (testamur status and clinical training) but fell short on achieving NBE certification rate and its ultimate impact on practice and patient care.

The 2019 ERS/ESTS/EACTS/ESTRO Guidelines on the Management of Patients With Malignant Pleural Mesothelioma.

Malignant pleural mesothelioma is a rare aggressive cancer, with insidious growth, and is associated with poor outcomes that have not improved over the years. A task force made up of members of the European Respiratory Society (ERS)/European Society of Thoracic Surgeons (ESTS)/European Association for Cardio-Thoracic Surgery (EACTS)/European Society for Radiotherapy and Oncology (ESTRO) societies, who are experts in the field of malignant mesothelioma, reviewed the literature from 2009 to 2018 to update the 2009 guidelines concerning epidemiology, diagnosis, staging, and treatment, including surgical, radiotherapy, and medical management, as well as palliative care to provide the best evidence-based recommendations for this patient population.

The Year in Thoracic Anesthesia: Selected Highlights From 2020.

Off-Pump Coronary Artery Bypass Grafting: Closing the Communication Gap Across the Ether Screen.

Cardiopulmonary bypass (CPB) has been one of the most important additions to the field of heart surgery in the past century. However, significant morbidity associated with CPB has led to the increasing implementation of off-pump coronary artery bypass (OPCAB). The use of OPCAB has broadened surgical revascularization for patient populations at high risk for undergoing CPB, including the very elderly and patients with impending end-organ failure. Intraoperative hemodynamic instability requires expeditious correction of hypotension with various medical and surgical techniques that require the close attention and skill of both the anesthesia and surgical teams. Technical skill at performing and interpreting transesophageal echocardiography is essential to help differentiate regional wall motion abnormalities from coronary ischemia and external compression from manipulation of the heart, which require different management strategies to resolve hemodynamic collapse. Flawless communication between the anesthesiologist and surgeons, with frequent intraoperative adjustments, is paramount for the completion of successful OPCAB.

Right ventricular function during and after thoracic surgery.

PURPOSE OF REVIEW: Right ventricular (RV) dysfunction following thoracotomy and pulmonary resection is a known phenomenon but questions remain about its mechanism, risk factors, and clinical significance. Acute RV dysfunction can present intraoperatively and postoperatively, persisting for 2 months after surgery. RECENT FINDINGS: Recently, the pulmonology literature has emphasized pulmonary arterial capacitance, rather than pulmonary vascular resistance, as a marker to predict disease progression and outcome in patients with pulmonary hypertension and heart failure. Diagnostic focus has emerged on the use of cardiac MRI and new echocardiographic parameters to better quantify the presence of RV dysfunction and the role of pulmonary capacitance in its development. SUMMARY: In this review, we examine the most recent literature on RV dysfunction following lung resection, including possible mechanisms, time span of RV dysfunction, and available diagnostic modalities. The clinical relevance of these factors on preoperative assessment and risk stratification are presented.
