Uncorrected congenital interatrial septal defect can be found in nearly a third of all adults and are associated with significant morbidity, including pulmonary hypertension, right-heart failure, atrial arrhythmias, and paradoxical embolic stroke. With advancing technology, percutaneous closure of atrial septal defects has become a viable alternative to open surgical repair. In this review, the authors provide 3 examples in which 3-dimensional interventional transesophageal echocardiogram effectively provided more precise visualization of the dynamic surface and geometry of the atrial septum and related structures than 2-dimensional TEE, permitting accurate sizing and repair of the defects.

Procedures and interventions in the cardiac catheterization laboratory (CCL) and electrophysiology laboratory (EPL) are more complex and involve acutely ill patients. Safely caring for this growing patient population in the CCL and EPL is now a concern for all anesthesiologists and cardiologists. Anesthesiologists are uniquely trained to care for this complex patient population, allowing the cardiologist to focus on completing the interventional procedure successfully.

Purpose of Review: The cardiac catheterization lab has concerns for both patient care and for safety. As the cardiac catheterization lab continues to evolve, the demand for anesthesia services will certainly increase. The role of the anesthesiologist in the cardiac catheterization lab must be defined in this changing environment., Recent Findings: Procedures in the cardiac catheterization lab are more complex, take longer, and involve higher acuity patients. Many of these cases require general anesthesia rather than sedation, and require management of unstable hemodynamics. Knowledge of echocardiography and fluoroscopy is beneficial. Anesthesiologists should be active in developing sedation and practice management guidelines. Radiation exposure and safety is an important concern., Summary: The anesthesiologist is becoming an integral part of the cardiac catheterization lab team, and an important element in maintaining a high level of patient care with minimal complications in the evolving modern day cardiac catheterization lab.
