Impact of change of ischemic burden on the outcomes of ESRD patients awaiting kidney transplantation.

Background: In asymptomatic patients with end-stage renal disease (ESRD) wait-listed for kidney transplantation (KT), it is unclear whether a change in ischemic burden on serial surveillance SPECT myocardial perfusion imaging (MPI) impacts outcome.

Methods And Results: In a retrospective cohort of 700 asymptomatic KT candidates with ≥ 2 sequential SPECT-MPI studies, we defined a significant change in ischemic burden between MPIs as ΔSDS of ≥ 2 points. Patients were followed for mean 19 ± 12 months after MPI for cardiac death or myocardial infarction.

Timing of Nonurgent Transesophageal Echocardiography and The Risk of Embolic Events Among Patients Admitted With Infective Endocarditis. A Review of the National Inpatient Sample.

In patients hospitalized for infective endocarditis (IE), timing of nonurgent transesophageal echocardiography (TEE) to reduce embolic events (EE) is unclear. In a retrospective cohort from the 2016 to 2018 combined National Inpatient Sample (NIS), Low-risk adults with IE who underwent nonurgent (>48 hours) TEE were stratified into 3 cohorts based on the timing of the first TEE: early-TEE (3-5 days), intermediate-TEE (5-7 days) and late-TEE (>7). The primary outcome was a composite of an embolic event.

A rare case of left dominant pulmonary edema in acute mitral regurgitation.

Unilateral pulmonary edema (UPE) due to cardiac causes is an unusual clinical finding and typically emerges on the right side. UPE poses a diagnostic challenge due to difficulty distinguishing infiltrative pneumonia from cardiogenic edema on chest imaging. Consequently, corrective clinical management is significantly delayed in UPE compared to bilateral cardiogenic pulmonary edema.

The prognostic and diagnostic implications of surveillance serial myocardial perfusion imaging in asymptomatic renal transplant candidates.

Background: The utility of serial SPECT myocardial perfusion imaging (MPI) for CAD surveillance in asymptomatic ESRD patients awaiting kidney transplantation (KT) is uncertain.

Methods And Results: We retrospectively investigated 700 asymptomatic KT candidates with ≥ 2 pre-transplant SPECT-MPIs (mean interval, 20 ± 13 months). Worsening MPI was defined as total perfusion deficit increase (ΔTPD) > 5%.
