Summary: Regadenoson Stress Echocardiography shows good agreement with gated-SPECT myocardial perfusion imaging, but its low sensitivity and negative predictive value limit its use in detecting myocardial ischemia as a bedside test.

Summary: Regadenoson, a selective A2A receptor agonist commonly used for vasodilator stress myocardial perfusion imaging, has been associated with rare but serious bradyarrhythmias, including asystole, in patients without known conduction system disease. Close monitoring and thorough risk assessment are essential for identifying and managing potential adverse effects in patients receiving Regadenoson.

Summary: The study examined the long-term survival of heart transplants in the recent era, finding no significant differences in post-transplant mortality based on toxicological and historical data. Factors positively associated with survival included lower donor age and shorter ischemic time.

Summary: This study demonstrates the therapeutic effects of intravenous infusion of low-dose bone marrow-derived MSCs in lung transplant patients. The results show that this treatment can slow the progression of chronic lung allograft syndrome in some patients and stabilize lung function decline.

Summary: The study analyzed two STP dosimetry methods and evaluated dose errors for different radiopharmaceuticals, finding that a lognormal distribution is more suitable for capturing effective half-life distributions. The STP methods showed promise for dosimetry of Lu-177-DOTATATE and kidney dosimetry, but may compromise accuracy for some radiopharmaceuticals.

Summary: In a retrospective cohort study of 10,275 consecutive patients who underwent regadenoson SPECT-MPI, abnormal perfusion and myocardial ischemia were found to be independently associated with an increase in major adverse cardiac events. These findings suggest that regadenoson stress SPECT-MPI can provide valuable prognostic information for patients.

Summary: Lowering elevated central venous pressure can reduce renal dysfunction in AHF patients. The Doraya catheter creates a pressure gradient to lower renal venous pressure. A feasibility study was performed on 9 AHF patients to evaluate the acute clinical effects of using the Doraya catheter in addition to standard diuretic-based regimen. The deployment of the Doraya catheter was safe and feasible, reducing central venous pressure and improving diuresis and signs of congestion.

Summary: Cardiac MRI with quantitative adenosine stress perfusion testing is safe and feasible for estimating myocardial perfusion in pediatric heart transplant patients. Myocardial perfusion reserve did not significantly differ between patients with coronary allograft vasculopathy and comparison patients. This method shows potential and warrants further investigation in a larger cohort.

Summary: In obese patients with non-dialysis-dependent kidney disease, simultaneous heart-kidney transplant (HKT) may decrease long-term mortality compared to isolated heart transplant (IHT), and should be strongly considered as a preferred treatment.
