Pneumopericardium after minimally invasive atrial septal defect closure.

Minimally invasive atrial septal defect (ASD) closure is a commonly performed cardiac surgical procedure and has good outcome. We report an interesting chest X-ray showing pneumopericardium in a patient who underwent ASD closure using a minimally invasive approach.

Cardiac output monitoring: comparison of a new arterial pressure waveform analysis to the bolus thermodilution technique in patients undergoing off-pump coronary artery bypass surgery.

Objective: To analyze the clinical agreement between the conventional intermittent bolus thermodilution (TD) technique and a new arterial pressure waveform analysis (APCO) technique (FloTrac; Edward Lifesciences, Irvine, CA) for cardiac output (CO) estimation.

Design: Prospective observational clinical study.

Setting: Cardiac surgery operating room of a tertiary care cardiac center.
