An alternative method for predicting the risk of postoperative complications in lung resection.

Objectives: The aims of this study were to design a best fit linear regression model to estimate VO2max (estimated VO2) and to compare the ability of VO2 values (measured and estimated) predicting cardiorespiratory complications in a series of patients undergoing lung resection for lung cancer.

Method: This was a prospective, observational study performed in 83 patients. Variables analyzed were: demographic characteristics, comorbidity, body mass index (BMI), FEV1%, FVC%, diffusion capacity (DLCO%), mean daily distance walked in kilometers, VO2max measured by cardio-pulmonary exercise test (CPET) and postoperative complications.

Amplatzer Amulet left atrial appendage occluder entrapment through mitral valve.

We report on a 77-year-old woman in whom percutaneous left atrial appendage (LAA) closure was performed. The patient had a left atrial myxoma resection 3 years previously, and 2 years later, she suffered a transient ischemic attack. Atrial fibrillation was detected and anticoagulation therapy was established.
