Anesthesia in adult patients with congenital heart disease

Eisenmenger Syndrome: JACC State-of-the-Art Review

Although major breakthroughs in the field of pediatric cardiology, cardiac surgery, intervention, and overall care improved the outlook of congenital heart disease, Eisenmenger syndrome (ES) is still encountered and remains a complex clinical entity with multisystem involvement, including secondary erythrocytosis, increased thrombotic and bleeding diathesis, high arrhythmogenic risk, progressive heart failure, and premature death. Clearly, care for ES is best delivered in multidisciplinary expert centers. In this review, we discuss the considerable recent progress in understanding the complex pathophysiology of ES, means of prognostication, and improvement in clinical outcomes achieved with pulmonary arterial hypertension-targeted therapies. Additionally, we delineate areas of uncertainty in various aspects of care, discuss gaps in current evidence, and review current status in less privileged countries and propose initiatives to reduce disease burden. Finally, we propose the application of emerging technologies to enhance the delivery and quality of health care related to ES and beyond.

Anesthetic Management in Adults with Congenital Heart Disease

PURPOSE OF REVIEW

Adults with congenital heart disease (ACHD) are a complex and growing population that presents numerous challenges for anesthetic management. This review summarizes special considerations for anesthetic management in ACHD.

RECENT FINDINGS

The adult patient with congenital heart disease may require anesthetic care for multiple surgeries and interventions throughout their lifetime. The cardiac and extracardiac manifestations of ACHD have important perioperative implications that affect anesthetic management. Recent American Heart Association/American College of Cardiology and European Society of Cardiology guidelines endorse a multidisciplinary, team-based approach to care. The cardiac anesthesiologist, endorsed as part of this multidisciplinary team, must have a thorough understanding of congenital heart disease pathophysiology and common extra-cardiac manifestations of ACHD. Safe anesthetic management in adult congenital heart disease should incorporate a multi-disciplinary approach to patient care. Anesthesiologists and centers with special expertise in ACHD care should be utilized or consulted whenever possible.

The Utility of Simulation in the Management of Patients With Congenital Heart Disease: Past, Present, and Future

Significant advancements have been made in the diagnosis and management of congenital heart disease (CHD). As a result, a higher percentage of these patients are surviving to adulthood. Despite this improvement in management, these patients remain at higher risk of morbidity and mortality, particularly in the perioperative setting. One new area of interest in these patients is the implementation of simulation-based medical education. Simulation has demonstrated various benefits across high-acuity scenarios encountered in the hospital. In CHD, simulation has been used in the training of pediatrics residents, assessment of intraoperative complications, echocardiography, and anatomic modeling with 3-dimensional printing. Here, we describe the current state of simulation in CHD, its role in training care providers for the management of this population, and future directions of CHD simulation.

Case Report: Emergency awake craniotomy for cerebral abscess in a patient with unrepaired cyanotic congenital heart disease

We report the case of a 39-year-old male with complex cyanotic congenital heart disease undergoing emergency craniotomy for a cerebral abscess. Maintenance of intraoperative hemodynamic stability and adequate tissue oxygenation during anesthesia may be challenging in patients with cyanotic congenital heart disease. In this case, we decided to perform the surgery as an awake craniotomy after interdisciplinary consensus. We discuss general aspects of anesthetic management during awake craniotomy and specific concerns in the perioperative care of patients with congenital heart disease.

Management of labour and delivery in congenitally corrected transposition of great arteries

A descriptive case report of the labour and delivery management of a 28-year-old woman who presented with congenitally corrected transposition of great arteries, dextrocardia, systemic ventricular dysfunction and junctional tachycardia. Patients with congenitally corrected transposition have a thin-walled morphological right ventricle as the systemic circulatory pump. The stress of increased cardiac output can lead to congestive heart failure, systemic atrioventricular valve regurgitation and arrhythmias. We used minimally invasive continuous cardiac output monitoring, fluid balance optimization and good maternal pain control to prevent decompensation and achieve vaginal delivery with a good maternal and neonatal outcome.

Advances in the Care of Adults With Congenital Heart Disease

The significant decline in mortality among children and adolescents with congenital heart disease (CHD) is associated with an increasing prevalence of CHD in adults, particularly those with moderate to severe defects. As a significant percentage of adolescents and young adults are lost to follow-up in the transition from pediatric to adult care, they may present for elective procedures with substantial CHD-associated morbidity. In addition to the specific cardiac defect, the procedures performed, and the current pathophysiological status, several factors should be considered when managing the adult with CHD. These include the type of setting (adult vs pediatric institution); surgeon (pediatric vs adult cardiac surgeon); coexisting diseases associated with CHD, such as coronary artery disease, hepatic dysfunction, renal dysfunction, cerebrovascular accidents, myopathy, and coagulation disorders; acquired diseases of aging; pregnancy; and psychosocial functioning. The current status of the management of common and important congenital cardiac defects is also described.

Anesthesia for the patient with congenital heart disease presenting for noncardiac surgery

PURPOSE OF REVIEW

To summarize recent publications emphasizing the changes in the population of patients with congenital heart disease and trends in the anesthetic and perioperative care of these patients presenting for noncardiac procedures.

RECENT FINDINGS

It has been reported that children with congenital heart disease presenting for noncardiac surgery are at an increased anesthetic risk. This risk has become better defined. The patients at highest risk are infants with a functional single ventricle and patients with suprasystemic pulmonary hypertension, left ventricular outflow tract obstruction or dilated cardiomyopathy. Familiarity with the physiology and perioperative implications of the stages of single ventricle palliation is critical. The anesthetic approach, monitoring, conduct of surgery and postoperative care and outcomes are variable in this patient population. Recent literature reflects the growing number of children with ventricular assist devices and the management of these patients for noncardiac procedures. Cardiac imaging modalities provide diagnostic information, and strategies for reducing anesthetic risk for these procedures are of great interest. Pharmacologic trends and the application of technology are reviewed.

SUMMARY

The identification of high-risk patients, multidisciplinary decision-making and planning and careful anesthetic management and monitoring are critical for optimizing outcomes in children with congenital heart disease presenting for noncardiac procedures.

Anaesthesia in the cardiac catheterization laboratory

PURPOSE OF REVIEW

Interventions in the cardiac catheterization laboratory (CCL) requiring anaesthetic expertise are becoming routine. These interventions involve a heterogeneous patient population and take place in an offsite location. This review aims to give an insight into anaesthetic issues surrounding certain interventions and the challenges encountered in an offsite location.

RECENT FINDINGS

Owing to an ageing population with increasing comorbidity, transcatheter interventions are being developed and in certain cases becoming routine alternatives for open heart operations. Percutaneous interventions are also being increasingly performed in adult patients with congenital heart abnormalities. The anaesthetic team plays an important role in these procedures, requiring detailed knowledge of the intervention, the characteristics of the patient population and the ability to work as a team in a complex, multidisciplinary setting.

SUMMARY

Interventions in the CCL have developed to such an extent that dedicated anaesthesia teams are required in order to cope with the complexities of the patient populations, the interventions and the challenges brought by the offsite nature of the CCL.
