Purpose To examine the clinical effect of lead length and lead orientation in patients with cardiac implantable electronic devices (CIEDs) and lead fragments or abandoned leads undergoing 1.5-T MRI. Materials and Methods This Health Insurance Portability and Accountability Act-compliant retrospective study included patients with CIEDs and abandoned leads or lead fragments undergoing 1.

Mid-cavitary variant Takotsubo cardiomyopathy (TCM) is uncommon and seen in only about 14% of all Takotsubo cases. Left ventricular thrombus (LVT) in the setting of mid-cavitary TCM is extremely rare, occurring in approximately 1% of cases.

Device-related thrombus is a recognized complication, but underlying mechanisms are incompletely understood. In this case series, the authors describe potentially the same mechanism of thrombosis with intraoperative images of incomplete endothelialization.

Her MM has been refractory to multiple chemotherapy regimens and two autologous bone marrow transplantation. Diagnostic evaluations including serum kappa and lambda chains, echocardiogram, pyrophosphate cardiac scan, and cardiac magnetic resonance were indicative of a progression to AL cardiomyopathy.

There are limited data on the head-to-head comparison of Tc-pyrophosphate (Tc-PYP) and echocardiographic strain imaging in the assessment of transthyretin (TTR) cardiac amyloidosis. At Mayo Clinic Arizona, patients who had undergone both a Tc-PYP scan and a transthoracic echocardiogram within a 90-d period were retrospectively identified for chart review and strain imaging analysis. Patients were divided into 2 groups according to their Tc-PYP results (PYP-positive [PYP+] or PYP-negative [PYP]) for the comparison.

In the modern era of renal replacement therapy, little is known about the prevalence and the implications of pericardial effusion in ESRD patients, its echocardiographic characteristics, and risk factors. We conducted a retrospective chart review on subjects > than 18 years of age with known ESRD who were undergoing outpatient evaluation for renal transplantation at Mayo Clinic Arizona between January 2001 and December 2015 and had baseline echocardiogram completed within 3 months of their initial evaluation.

Radiation is an important consideration, and attempts to minimize exposure should be implemented. Efficiency and cost effectiveness are cornerstones in the delivery of quality patient care and should also be considered when implementing change.

Cardiorespiratory fitness, as measured by peak oxygen uptake (VO), is an established validated predictor of future cardiovascular morbidity and mortality in both healthy and diseased populations. The literature supports its use among asymptomatic patients in abrogating the need for further cardiac testing.

Echocardiographic speckle-tracking strain and strain rate have been used to evaluate and detect subclinical myocardial dysfunction in patients receiving cardiotoxic chemotherapy, and patients with valvular heart disease. This technology was applied to evaluate the effects of pectus excavatum surgery on left ventricular (LV) and right ventricular (RV) function.

In parallel with senescence, comorbidities are present, one such example being chronic obstructive pulmonary disease (COPD), which causes significant disability and is the third leading cause of death in the United Sates (2). The presence of COPD is associated with increased perioperative complications, and serve as a reason to deny a patient surgical intervention because of the increased surgical risk (3).

Objectives: We sought the impact of recent recommendations on observer concordance on interpretation of diastolic stage and assessment of filling pressure.
Background: Worsening stages of diastolic dysfunction are associated with worsening outcome. However, the echocardiographic classification of diastolic function is complex, and parameters may be discordant.
