Real-Time Three-Dimensional Echocardiographic Study of Left Ventricular Function After Infarct Exclusion Surgery for Ischemic Cardiomyopathy

Relationship Between Early Diastolic Intraventricular Pressure Gradients, an Index of Elastic Recoil, and Improvements in Systolic and Diastolic Function

“…In addition, IES, a technique in which the LV is surgically remodeled by resecting apical tissue scarred by myocardial infarction, has also recently been shown both by our group and others to result in significant improvements in LV systolic and diastolic function. [17][18][19] Inclusion of these patients was done to illustrate that improvements in IVPG can also occur with iatrogenic changes in ventricular geometry. Although the independent effects of IES cannot be separated from the effects of revascularization, the inclusion of these different operative modalities clearly illustrates the increases in ventricular suction that coincide with improvements in both systolic and diastolic function.…”

“…IES was performed based on techniques described previously. 8 Each patient was successfully and completely weaned from CPB with intermittent volume infusions from the CPB circuit to obtain adequate hemodynamics by increasing preload. At this time, after rezeroing, the catheter was repositioned across the mitral valve, and multiple hemodynamic measurements were obtained in 8-second intervals during different stages of physiological stabilization to allow for matching of the hemodynamic data with pre-bypass values.…”

Importance of Mitral Valve Repair Associated With Left Ventricular Reconstruction for Patients With Ischemic Cardiomyopathy: A Real-Time Three-Dimensional Echocardiographic Study

“…[1][2][3][4] In our previous studies, we demonstrated that LV reconstruction surgery combined with coronary revascularization for patients with ICM could significantly reduce symptoms in patients refractory to medical therapy and that an LV end-diastolic volume Ͻ150 mL after surgery predicted a favorable short term outcome. 3,5 In contrast, persistent mitral regurgitation (MR) was found to be a strong predictor of poor long-term prognosis. Though repair of ischemic MR with a mitral ring annuloplasty and coronary revascularization may achieve immediate valve competence, a number of patients develop recurrent MR at intermediate follow-up.…”

Beating Atrial Septal Defect Closure Monitored by Epicardial Real-Time Three-Dimensional Echocardiography Without Cardiopulmonary Bypass

“…3 To overcome such limitations, a variety of 3D echocardiographic systems have been developed during the past decade, including a system that reconstructs a series of 2D echocardiographic images. 4 Nevertheless, the current system of 3D reconstruction from multiple cross-sectional echocardiographic scans is still cumbersome and time-consuming, and the reconstruction process requires a substantial learning curve. 5 Imaging time is shorter with RT3DE than with 3D reconstruction techniques applied to 2D echocardiography, because all planes are imaged simultaneously.…”

“…This new methodology makes it possible to obtain both qualitative and quantitative information on cardiac disorders. [3][4][5][6] Schmidt et al 7 demonstrated that 3D echocardiography allows rapid and accurate measurement of left ventricular volume and mass. Nevertheless, because it takes a long time to display the 3D images, 3D ultrasonography can generally only be used as a diagnostic method and not to assist treatment, except according to a few reports.…”
