Predischarge Transthoracic Echocardiography after Surgery for Congenital Heart Disease: A Routine with a Reason?
Predischarge (pre-d/c) transthoracic echocardiography (TTE) is routine after surgery for congenital heart disease, but how it affects clinical care is unknown. The aim of this study was to test the hypothesis that pre-d/c TTE frequently reveals findings associated with short-term clinical course through a systematic review of findings on pre-d/c TTE and clinical events that followed. ⋯ Findings on pre-d/c TTE are frequent, commonly discordant with postoperative transesophageal echocardiographic results, and associated with adverse clinical events after surgery for congenital heart disease. These data would strongly support the practice of pre-d/c TTE after surgery for congenital heart disease.

Focused Cardiac Ultrasound in Place of Repeat Echocardiography: Reliability and Cost Implications.
Health care systems are increasingly moving toward models that emphasize the delivery of high-quality health care at lower costs. Rates of repeat echocardiography (two or more transthoracic echocardiographic studies performed within a short interval) are high and can contribute substantially to the cost of providing cardiovascular care. Certain findings from handheld ultrasound scans performed by echocardiographers have been shown to correlate well with findings on transthoracic echocardiography (TTE). It therefore may be feasible and cost effective to use expert focused cardiac ultrasound (eFCU) in place of repeat TTE for highly selected indications in certain settings. The aim of this study was to determine the reliability and cost implications of using eFCU in place of repeat TTE in selected inpatients. ⋯ Findings from eFCU correlate well with those from TTE when used in the setting of repeat testing for assessment of ventricular function, pericardial effusion, and inferior vena cava collapse. The judicious use of eFCU in place of repeat inpatient TTE has the potential to deliver quality cardiac imaging at reduced cost.

Quantitative Modeling of the Mitral Valve by Three-Dimensional Transesophageal Echocardiography in Patients Undergoing Mitral Valve Repair: Correlation with Intraoperative Surgical Technique.
Mitral valve (MV) repair is the procedure of choice for patients with degenerative MV disease (DMVD) with severe mitral regurgitation. The aim of this study was to identify specific quantitative MV parameters from preoperative three-dimensional (3D) transesophageal echocardiography that are associated with the length of the mitral annuloplasty band implanted and the performance of leaflet resection in patients with DMVD undergoing MV repair. ⋯ In DMVD, quantitative 3D annular circumference obtained from semiautomatically generated parametric maps of the MV from 3D transesophageal echocardiographic data was associated with the surgically implanted annuloplasty band length, while P2 leaflet length ≥ 20 mm and area ≥ 3.4 cm(2) were associated with the performance of leaflet resection. These parameters should be further investigated for preoperative planning in patients with DMVD undergoing MV repair.

Assessment of Biventricular Function by Three-Dimensional Speckle-Tracking Echocardiography in Secondary Mitral Regurgitation after Repair with the MitraClip System.
The goal of this study was to determine changes in left ventricular (LV) and right ventricular (RV) function with three-dimensional (3D) speckle-tracking echocardiography (STE) after percutaneous mitral valve repair with the MitraClip system in high-risk surgical patients with moderate to severe or severe secondary mitral regurgitation (MR). ⋯ Three-dimensional STE showed overall LV and RV strain improvement after clip implantation as well as lower postprocedural LV strain values in patients with worse preexisting RV function. These findings could help in guiding MR treatment strategies, suggesting different therapies in the presence of marked RV impairment or anticipating the procedure in case of evolving RV dysfunction.
