This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...

ConclusionsParasternal minimally ‐invasive aortic valve replacement is a feasible technique associated with a slow learning curve but the potential to achieve improved outcomes. Considering the transcatheter alternatives, the relative risk reduction may be worth investigating in future trials.

ConclusionLow-CM third-generation-DSCT achieves good IQ in TAVR candidates with CKD, and seems safe, with no apparent renal function deterioration or prevalence of PC-AKI. However, standard-CM protocols in non-CKD patients provide higher measurement reproducibility. Low-CM protocols should therefore be reserved for patients at high risk for PC-AKI.

ConclusionIn the current scenario, tissue engineering and cell therapy employ an innovative approach to reduce the mortality rate. However, the main challenge for this is customization, which is somewhat taken up by AM technologies. This technology has already addressed different challenges in the medical field. For tissue and organ printing, this technique seems better as compared to 2D conventional cell technique. With the help of scanned data, 3D printing allows us to create intricate internal structures. Thus, it can be used to develop bone tissues, which are required for clinical applications towards the treatment of ...

Abstract OBJECTIVES: To evaluate accuracy of virtual-non-contrast images (VNC) compared to true-unenhanced-images (TNC) for evaluation of liver attenuation acquired using spectral-detector CT (SDCT). METHODS: 149 patients that underwent multiphase transcatheter-aortic-valve-replacement (TAVR) SDCT-examinations (unenhanced-chest [TNC], CT-angiography chest [CTA-Chest, early arterial-phase] and abdomen [CTA-Abdomen, additional early arterial-phase after a second injection of contrast media]) were retrospectively included. VNC of CTA-Chest (VNC-Chest) and CTA-Abdomen (VNC-Abdomen) were reconstructed and compared...

Conclusion: The cumulative incidence of permanent pacemaker implantation following SAVR was about 12% at 10 years, with every other patient having VPP ≥90% during follow-up. This suggests that AV node conduction disturbances extend significantly beyond the perioperative period. PMID: 31809597 [PubMed - as supplied by publisher]

Publication date: Available online 6 December 2019Source: Annals of Medicine and SurgeryAuthor(s): Alaa S. Bahjat, Ahamd Mohammad Sharif Tahir, Ayad Ahmad MohammedAbstractHydatid cyst of the heart is very rare, the left ventricle is the commonest site of myocardial involvement due to dominant left coronary vessels and thicker wall. Isolated cardiac involvement is extremely rare. Patients may be quite asymptomatic but the cyst may cause palpitation, dyspnea, chest pain, or when ruptured in to the cardiac or pericardial cavities may cause emergency presentations like anaphylactic reactions, sudden collapse due to pericardial...

CONCLUSIONS: A tortuous abdominal aorta was found to be a predictor of the occurrence of a complication in patients undergoing transfemoral transcatheter aortic valve replacement. This computed tomography variable should therefore be taken into account when choosing the approach, especially for patients at intermediate and low surgical risk.

Transcatheter aortic root repair (TARR) is still not available because of the complex anatomy. In order to develop future TARR technologies, a human-derived bench test model is required before performing animal tests. For this purpose, we aimed to validate computed tomography (CT)-derived 3D-printed root models for TARR technologies. Four human CT-derived roots were printed using different resins: Visijet M3 Crystal, Photopolymer gel SUP705, Formlabs flexible resin, and Materialise HeartPrint Flex. A stress test was performed using a 26-mm balloon-expandable Sapien valve deployed in aortic position. The too rigid Visijet M...
