Measurement of the Aortic Annulus Area and Diameter by Three-Dimensional Transesophageal Echocardiography in Transcatheter Aortic Valve Replacement.

Objectives: Sizing of the aortic valve is crucial for transcatheter aortic valve replacement (TAVR). Multidetector computed tomography (MDCT) is used for sizing. Recently, three-dimensional transesophageal echocardiography (3DTEE) has enabled accurate measurement of the aortic annulus area and diameter in cases that are difficult to measure.

Accuracy and Trending Ability of the Fourth-Generation FloTrac/Vigileo System in Patients With Low Cardiac Index.

Objectives: To determine the accuracy and trending ability of the fourth-generation FloTrac/Vigileo in patients with low cardiac index by comparing FloTrac/Vigileo-derived cardiac index with that measured by 3-dimensional echocardiography.

Design: Prospective clinical study.

Setting: Cardiac surgery operating room in a single cardiovascular center.

Contralateral tension pneumothorax during video-assisted thorascoscopic surgery for lung cancer: a case report.

Contralateral tension pneumothorax during one-lung ventilation is a rare but catastrophic surgical complication. A 72-year-old Japanese male with lung cancer underwent right upper lobectomy with video-assisted thoracoscopic surgery. Despite use of various methods for maintaining oxygenation during one-lung ventilation, percutaneous oxygen saturation was unstable from the start of surgery and suddenly decreased with a drop in blood pressure.
