Comparative StudyAccuracy of transthoracic echocardiography for the measurement of the ascending aorta: comparison with transesophageal echocardiography.
There has been a substantial increase in the number of imaging studies performed to assess thoracic aortic pathology. We sought to determine the accuracy of transthoracic echocardiography (TTE) compared to transesophageal echocardiography (TEE) for measuring ascending aortic size. ⋯ Transthoracic echocardiography using nonstandard imaging windows is accurate in comparison to TEE for measurement of the ascending aorta at multiple levels in patients with or without aortic pathology. The findings of this study provide support for selected serial follow-up of patients with aortic disease by TTE only.

Review Case ReportsLate perforation by cardiac implantable electronic device leads: clinical presentation, diagnostic clues, and management.
Late intracardiac lead perforation is defined as migration and perforation of an implanted lead after 1 month of cardiac electronic device implantation. It is an under-recognized complication with significant morbidity and mortality, particularly if not recognized early. ⋯ We conducted a thorough review of the available English language literature pertaining to this complication to draw relevant conclusions regarding presentation, diagnosis, and management. Early recognition of this complication is important as the indications for and numbers of patients who receive cardiac implantable electronic devices continue to expand.
