Prolonged Corrected QT Interval in the Donor Heart: Is There a Risk?

Assessing the QT interval in donors is important to exclude long QT syndrome as the cause of death. A donor heart with a corrected QT (QTc) >500 milliseconds is often concerning. We sought to evaluate first year outcomes for donors with a QTc interval >500 milliseconds.

Typical angina is associated with greater coronary endothelial dysfunction but not abnormal vasodilatory reserve

Typical angina (TA) is defined as substernal chest pain precipitated by physical exertion or emotional stress and relieved with rest or nitroglycerin. Women and elderly patients are usually have atypical symptoms both at rest and during stress, often in the setting of nonobstructive coronary artery disease (CAD).

ANGIOGRAPHIC DYE PRIOR TO COMBINED HEART-KIDNEY DONATION DOES NOT APPEAR TO HARM DONOR KIDNEY FUNCTION AFTER TRANSPLANT

Background: Patients(pts) with end-stage heart disease and renal disease may require combined heart-kidney transplant (HKTx). For donors ≥40 years, a coronary angiogram is often performed to exclude donor coronary artery disease, exposing these older donor kidneys to contrast. Further contrast may
