Echocardiography

Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients. ⋯ To our knowledge, this is the first prospective study to evaluate the correlation between the echocardiographic parameters for RV systolic function and MRI RVEF in heart transplantation recipients. RV FAC is the only parameter to correlate well with MRI RVEF, and its routine use in the follow-up of heart transplantation recipients should be considered.

Left atrial appendage (LAA) closure prevents thromboembolic risk and avoids lifelong anticoagulation due to atrial fibrillation (AF). Nowadays, AtriClip, a modern epicardial device approved in June 2010, allows external and safe closure of LAA in patients undergoing cardiac surgery during other open-chest cardiac surgical procedures. Such a surgical approach and its epicardial deployment differentiates LAA closure with AtriClip from percutaneous closure techniques such as Watchman (Boston Scientific, Marlborough, MA, USA), Lariat (SentreHEART Inc., Redwood City, CA, USA), and Amplatzer Amulet (St. ⋯ Paul, MN, USA) device procedures. AtriClip positioning must consider perioperative transesophageal echocardiography (TEE) to confirm LAA anatomical features, to explore the links with neighboring structures, and finally to assess its successful closure. We report a sequence of images to document the role of intraoperative TEE during an elective aortic valve replacement and LAA external closure with AtriClip.

Invagination of an appendage into the left atrium is a rare complication. It occurs spontaneously or after open-heart surgery. ⋯ Herein, we provide echocardiographic images before, during, and after manual reversion of the left appendage. Misdiagnosis of this complication could have led to an additional unnecessary surgical procedure that could have impacted on the patient's morbidity.
