Background: Coronary computed tomography angiography (CCTA) is emerging as a valuable tool for noninvasive surveillance of cardiac allograft vasculopathy (CAV) in patients with heart transplant (HTx). We assessed the diagnostic performance of a comprehensive CCTA-based approach compared with the invasive reference, which includes invasive coronary angiography, intravascular ultrasound, and fractional flow reserve, for detecting CAV.
Methods: This was a multicenter prospective study including 37 patients with HTx who underwent CCTA, invasive coronary angiography, intravascular ultrasound, and fractional flow reserve.
Assessing subaortic right ventricle function after atrial switch repair through myocardial work analysis.
Int J Cardiol Congenit Heart Dis

Background: The Mustard and Senning operations for dextro-transposition of the great arteries (D-TGA) establish a biventricular physiology with a subaortic right ventricle (sRV). While prolonged QRS has been associated with worse prognosis in these patients, current echocardiographic tools fall short in adequately assessing the (mal)performance and function decline of the sRV during follow-up. The present study is the first to characterize Myocardial Work (MW) indices of the sRV in D-TGA patients after Mustard/Senning repair.

Article Synopsis
- The study examines gender differences in the relationship between angiographic findings and fractional flow reserve (FFR) in patients with coronary stenosis.
- Median FFR values were found to be higher in female patients than in male patients, and a 50% diameter stenosis (DS) is identified as the best threshold for detecting ischemic FFR in both genders.
- While a higher DS threshold (≥ 59%) improves lesion classification in females, it also results in a higher rate of false negatives.
Impact of Robotic Percutaneous Coronary Intervention (R-PCI) With and Without CCTA-Guidance on Clinical Outcomes and Hospital Economics: A Single Center Registry.
Catheter Cardiovasc Interv
December 2024
Article Synopsis
- Robotic-assisted coronary interventions (R-PCI) have shown safety and effectiveness in treating various coronary lesions, but their real-world clinical outcomes remain unclear.
- A study evaluated 111 patients to assess major adverse cardiovascular events (MACE) and found a low occurrence of 5.4% during a median follow-up period.
- The research indicated that while procedural complexity increased time and radiation exposure, it did not impact in-hospital or long-term outcomes, and CCTA-guided procedures allowed for a higher rate of same-day discharge (64.6% vs. 44.2%).
