Intraoperative high and low blood pressures are not associated with delirium after cardiac surgery: A retrospective cohort study.

Study Objective: To evaluate the associations between high and low intraoperative time-weighted average mean arterial pressures before, during and after cardiopulmonary bypass on postoperative delirium.

Design: Single center retrospective cohort study.

Setting: Operating rooms and postoperative care units.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database: Intraoperative Echocardiography Reporting.

Objectives: To identify trends in the reporting of intraoperative transesophageal echocardiographic (TEE) data in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) and the Adult Cardiac Anesthesiology (ACA) module by period, practice type, and geographic distribution, and to elucidate ongoing areas for practice improvement.

Design: A retrospective study.

Setting: STS ACSD.

Perioperative Assessment of the Hemodynamic Ventriculoarterial Junction of the Aortic Root by Three-Dimensional Echocardiography.

Improved strategies in aortic valve-preserving operations appreciate the dynamic, three-dimensional complexity of the aortic root and its valve. This depends not only on detailed four-dimensional imaging of the planar dimensions of the aortic root but also on quantitative assessment of the valvar leaflets and their competency. The zones of apposition and resulting hemodynamic ventriculoarterial junction formed in diastole determine valvar competency.

Practical Considerations for Obtaining Perioperative Transesophageal Echocardiography Accreditation: Collective Experiences at Early-Adopting Centers.

The Intersocietal Accreditation Commission (IAC) is a nonprofit accrediting organization committed to ensuring the quality of diagnostic imaging and related procedures. It comprises a collaboration of stakeholders spanning numerous medical professionals and specialties. In a recent initiative, IAC Echocardiography introduced a new accreditation specifically for Perioperative Transesophageal Echocardiography (PTE).

Obstructed Supramitral Inflow: Cor Triatriatum Sinister Presentation in Adulthood.

Cor triatriatum is a rare congenital heart defect that occurs when a fibromuscular membrane divides the atrium into two chambers, which may impair blood flow to the ventricle. When it does, the symptoms usually manifest during infancy or early childhood. In this E-challenge, though, the case of a 40-year-old man is reviewed whose symptoms of shortness of breath progressed over the years and were attributed to the diminished mitral valve inflow due to the restricted cor triatriatum sinister associated with pulmonary hypertension, tachycardia-bradycardia syndrome, and atrial fibrillation.

Arterial Hyperoxemia During Cardiopulmonary Bypass Was Not Associated With Worse Postoperative Pulmonary Function: A Retrospective Cohort Study.

Background: Arterial hyperoxemia may cause end-organ damage secondary to the increased formation of free oxygen radicals. The clinical evidence on postoperative lung toxicity from arterial hyperoxemia during cardiopulmonary bypass (CPB) is scarce, and the effect of arterial partial pressure of oxygen (Pa o2 ) during cardiac surgery on lung injury has been underinvestigated. Thus, we aimed to examine the relationship between Pa o2 during CPB and postoperative lung injury.

Serratus anterior and pectoralis plane blocks for robotically assisted mitral valve repair: a randomised clinical trial.

Background: Minimally invasive cardiac surgery provokes substantial pain and therefore analgesic consumption. The effect of fascial plane blocks on analgesic efficacy and overall patient satisfaction remains unclear. We therefore tested the primary hypothesis that fascial plane blocks improve overall benefit analgesia score (OBAS) during the initial 3 days after robotically assisted mitral valve repair.

Association of Conventional Ultrafiltration on Postoperative Pulmonary Complications.

Background: Postoperative pulmonary complications increase mortality after cardiac surgery. Conventional ultrafiltration may reduce pulmonary complications by removing mediators of bypass-induced inflammation and countering hemodilution. We tested the primary hypothesis that conventional ultrafiltration reduces postoperative pulmonary complications, and secondarily, improves early pulmonary function assessed by the ratio of PaO to fractional inspired oxygen concentration.

Post-cardiopulmonary bypass longitudinal strain provides higher prognostic ability than baseline strain or change in strain.

Context: Global longitudinal strain (GLS) measured by speckle-tracking echocardiography demonstrates excellent prognostic ability in predicting major adverse cardiac events after cardiac surgery. However, the optimal timing of intraoperative GLS measurement that provides the best prognostic value is unclear.

Aim: Our goal was to evaluate whether GLS measured prior to cardiopulmonary bypass (pre-CPB GLS), following CPB (post-CPB GLS), or change in GLS provides the strongest association with postoperative complications.

Left Ventricular Twist Mechanics Before and After Aortic Valve Replacement: A Feasibility Study and Exploratory Analysis.

We examined whether intraoperative assessment of left ventricular (LV) twist mechanics is feasible with transesophageal echocardiography (TEE). We then explored whether twist mechanics were altered by hemodynamic conditions or patient comorbidities. In this sub-analysis of clinical trial data, transgastric short-axis echocardiographic images of the LV base and apex were collected in patients having aortic valve replacement (AVR) at baseline and end of surgery.

Comparing outcomes of general anesthesia and monitored anesthesia care during transcatheter aortic valve replacement: The Cleveland Clinic Foundation experience.

Background: Monitored anesthesia care (MAC) has become more widely used during transcatheter aortic valve replacement (TAVR) to avoid the complications of general anesthesia (GA).

Methods: We included consecutive patients who underwent transfemoral-TAVR at our institution between January 2012 and April 2017. We compared outcomes with GA versus MAC.

Patient characteristics and surgical variables associated with intraoperative reduced right ventricular function.

Objective: Perioperative right ventricular function is a significant predictor of patient outcomes after cardiac surgery. This prospective study aimed to identify perioperative factors associated with reduced intraoperative right ventricular function.

Methods: Right ventricular function was assessed at the beginning and end of surgery by standardized transesophageal echocardiographic measurements, including tricuspid annular plane systolic excursion, peak systolic longitudinal right ventricular strain, and fractional area change, in 109 adult patients undergoing cardiac surgery at Cleveland Clinic.

Neither Preoperative Pulse Pressure nor Systolic Blood Pressure Is Associated With Cardiac Complications After Coronary Artery Bypass Grafting.

Background: Increased pulse pressure has been associated with adverse cardiovascular events, cardiac and all-cause mortality in surgical and nonsurgical patients. Whether increased pulse pressure worsens myocardial injury and dysfunction after cardiac surgery, however, has not been fully characterized. We examined whether cardiac surgical patients with elevated pulse pressure are more susceptible to myocardial injury, dysfunction, cardiac-related complications, and mortality.

Intercostal Blocks with Liposomal Bupivacaine in Thoracic Surgery: A Retrospective Cohort Study.

Objective: Assess the efficacy of adding liposomal bupivacaine (LB) to bupivacaine-containing intercostal nerve blocks (ICNBs) to improve analgesia and decrease opioid consumption and hospital length of stay compared with bupivacaine-only ICNBs.

Design: This retrospective, observational investigation compared pain intensity scores and cumulative opioid consumption within the first 72 postoperative hours in patients who received ICNBs with bupivacaine plus LB (LB group) versus bupivacaine only (control group) after minimally invasive anatomic pulmonary resection. LB was tested for noninferiority on pain scores and opioid consumption.

Pulmonary Venous Flow After Lung Transplantation: Turbulence and High Velocities.

Lung transplantation is the definitive treatment for end-stage lung disease. The pulmonary venous anastomosis has the potential for significant obstructive complications that can lead to considerable morbidity and mortality. The use of intraoperative transesophageal echocardiography, including color-flow and spectral Doppler, is instrumental in evaluating the pulmonary veins after lung transplantation.

Regional Anesthesia in Cardiac Surgery: An Overview of Fascial Plane Chest Wall Blocks.

Optimal analgesia is an integral part of enhanced recovery after surgery (ERAS) programs designed to improve patients' perioperative experience and outcomes. Regional anesthetic techniques in a form of various fascial plane chest wall blocks are an important adjunct to the optimal postoperative analgesia in cardiac surgery. The most common application of fascial plane chest wall blocks has been for minimally invasive cardiac surgical procedures.

Methylprednisolone Does Not Reduce Acute Postoperative Pain After Cardiac Surgery: Subanalysis of a Randomized Clinical Trial.

Background: Pain after cardiac surgery is largely treated with opioids, but their poor safety profile makes nonopioid medications attractive as part of multimodal pathways. Anti-inflammatory drugs reduce acute postoperative pain, but the role of steroids in reducing acute poststernotomy pain is unclear. We evaluated the association between the intraoperative administration of methylprednisolone and postoperative analgesia, defined as a composite of pain scores and opioid consumption, during the initial 24 hours after cardiac surgery.
