Aims: Concomitant coronary artery disease (CAD) is frequent in transcatheter aortic valve implantation (TAVI) candidates. Despite societal recommendations of performing invasive coronary angiography (ICA) for coronary assessment in the pre-TAVI diagnostic workup, the prognostic value of ICA and beneficial effect of revascularization in these patients remains unclear. We aimed to determine feasibility and outcomes following a strategy of cardiac CT + coronary CT angiography (cCTA) rather than cardiac CT + ICA before TAVI.

- Coronary computed tomography angiography (CCTA) is useful for analyzing coronary atherosclerotic plaques, but previous studies on the consistency of plaque volume measurements between scans are limited.
- In a study involving 101 patients, CCTA scans were performed twice with a one-hour interval using identical protocols, and plaque volumes were assessed using semi-automated software.
- Results showed high correlation for total, non-calcified, and calcified plaques, but lower for low-density non-calcified plaques, with reproducibility influenced by image quality, reconstruction settings, and lesion location, particularly in left anterior descending (LAD) arteries.
Article Synopsis
- A study examined the relationship between how completely patients with stable angina were revascularized (opened blocked arteries) and their cardiovascular health outcomes, using a method called fractional flow reserve (FFR) to measure artery health.
- In 900 patients, those who were incompletely revascularized had a significantly higher risk of cardiovascular events, like heart attacks, compared to those who were completely revascularized or had normal FFR readings.
- The findings suggest that ensuring complete revascularization in patients with critical artery blockages (FFR ≤ 0.80) could lead to better heart health outcomes.
Introduction: Coronary CT angiography (CTA) derived fractional flow reserve (FFR ) shows high diagnostic performance when compared to invasively measured FFR. Presence and extent of low attenuation plaque density have been shown to be associated with abnormal physiology by measured FFR. Moreover, it is well established that statin therapy reduces the rate of plaque progression and results in morphology alterations underlying atherosclerosis.

From the histological point of view, several situations may arise.
Patients And Methods: We analyzed the clinical, hormonal, sonographic, and genitographics data, as well as peroperative and histological findings for five cases of mosaicism 45, X/46, XY, and we discussed treatment performed.
