ReviewTransesophageal echocardiography in thoracic anesthesia: pulmonary hypertension and right ventricular function.
Pulmonary hypertension is associated with increased postoperative morbidity and mortality. Early diagnosis and echocardiographic detection of right ventricular (RV) dysfunction are paramount in perioperative management. The goal of this review is to provide an overview of the recent literature on this topic. ⋯ More pulmonary hypertension patients are presenting for noncardiac surgery, creating a challenge for the anesthesiologist. Echocardiographic detection of RV dysfunction can be difficult. Routine use of intraoperative transesophageal echocardiography in major thoracic surgery is not advocated yet, but the development of automated techniques may provide an objective assessment of RV function.

ReviewDiastolic dysfunction, diagnostic and perioperative management in cardiac surgery.
The review focuses on recent findings on the role of diastolic dysfunction in the perioperative period and on recent advances in the diagnosis and perioperative management of diastolic function. ⋯ Appropriate perioperative patient care requires that the perioperative physician be alerted to the presence of diastolic dysfunction, be knowledgeable of the diastolic dysfunction grading system and understand the pathophysiologic changes associated with various grades of diastolic function.

Review Case ReportsPreoperative evaluation of the patient with lung cancer being considered for lung resection.
This review summarizes the general approach to evaluating the cardiopulmonary fitness of a patient with lung cancer being considered for lung resection. Many patients have a high risk for morbidity and mortality from lung resection owing to severe comorbidities or low cardiopulmonary reserve. A comprehensive and individualized assessment is essential to identify the factors that may impact operative outcome. ⋯ Preoperative assessment requires an understanding of the relative benefits and harms of available treatment options and consideration of patients' values. A balance between the potential to cure one's cancer and the short-term and long-term risks of the selected treatment needs to be reached. All patients should have a baseline FEV(1) and DL(CO) measured, and predicted postoperative FEV(1) and DL(CO) calculated to assist with risk prediction. Measures of exercise performance can help to further risk stratify patients. Means of modifying the risks should be considered for all patients.

Aortic stenosis is the most frequent valvular heart disease in the USA, and aortic valve replacement remains the only definitive treatment. For patients who cannot have surgery or who are at an increased risk for surgical aortic valve replacement (SAVR), transcatheter aortic valve replacement (TAVR) has become an established treatment option. New technological developments in valve design will make TAVR available to an even wider group of patients. This review describes the TAVR procedure and its critical stages. ⋯ TAVR is a treatment option for patients who are at an increased risk for SAVR. Evolving technology will likely expand the patient population eligible for this type of treatment in the very near future. Multidisciplinary heart team is essential in improving current techniques and patient selection, as well as evaluating new technologies.

ReviewExpanding role of perioperative transesophageal echocardiography in the general anesthesia practice and residency training in the USA.
To review the perioperative use of noncardiac transesophageal echocardiography in anesthesiology and to explore the current mechanisms of teaching and certification. ⋯ Transesophageal echocardiography can have many helpful uses in perioperative patient care. This study summarizes many noncardiac uses, certification, and echocardiography education for anesthesiologists.
