Improved outcomes in survivors of cardiac arrest qualified to early coronary angiography - a single tertiary centre study.

Introduction The majority of cardiac arrests in adults are related to coronary artery disease, and the role of early invasive cardiology procedures remains unclear. Aims We investigated the prognosis of patients hospitalized due to out-ofhospital cardiac arrest or in-hospital cardiac arrest within 24 hours of admission to tertiary cardiology, focusing on early coronary angiography and percutaneous coronary intervention, as well as percutaneous coronary intervention. And after adjustment for other causes, the risk of death was lower among patients who underwent early CA or received at least one defibrillation. Patients who underwent cardiac arrest in a tertiary cardiac center had improved outcomes after cardiac arrest, according to this collection. The early CA and initial shockable rhythm improved survival, with lower SpOu2082 lower EF and NSTEMI as independent risk factors for death in a multivariable logistic regression model.

Early coronary angiography in patients after out-of-hospital cardiac arrest without ST-segment elevation: Meta-analysis of randomized controlled trials.

Objects Objectives: To compare early coronary angiography to a more effective or selective strategy in out-of-hospital cardiac arrest without ST-segment rise of potential cardiac cause by means of meta-analysis of available randomized controlled trials. Methods We investigated MEDLINE and the Cochrane Central Register of Controlled Trials for RCTs comparing early with delayed or selective coronary angiography in OHCA patients of suspected cardiac origin without ST-segment elevations. Results The search engine found three RCTs enrolling a total of 1167 patients, resulting in the search algorithm. Conclusion Early coronary angiography in OHCA without ST-segment elevation is not superior compared to a delayed/selective strategy.

Heart Rate-Dependent Degree of Motion Artifacts in Coronary CT Angiography Acquired by a Novel Purpose-Built Cardiac CT Scanner.

For several patients, adequate HR monitoring remains a challenge, with the goal heart rate undergoing coronary CT angiography remaining of importance. By further improving temporal resolution, Purpose-built cardiac scanners may provide optimal image quality at higher HRs. We wanted to measure the amount of motion artifacts on CCTA obtained using a dedicated cardiac CT scanner rather than a traditional multidetector CT scanner. We compared 80 DCCT scans to 80 MDCT scans matched by sex, age, HR, and coronary dominance in 80 DCCT scans.

Diagnostic accuracy of cardiac computed tomographic angiography and transesophageal echocardiography in evaluation of patients with prosthetic paravalvular leakage.

Purpose: The aim of this survey was to gather diagnostic data for patients with prosthetic heart valve dysfunction. Materials and methods This was a prospective cohort study that was conducted on 26 patients with suspected prosthetic PVL who underwent both transesophageal echocardiography and 64-slice ECG-gated CT. By TEE, the perimeter of prosthetic PVL measured by CT was highly correlated with echocardiographic severity of PVL. Conclusions This research reveals that cardiac CT demonstrated comparable diagnostic accuracy to TEE and intraoperative results for the detection, localization, and assessment of prosthetic PVL severity.

Assessment of Device Neoendothelialization With Cardiac Computed Tomography Angiography After Transcatheter Closure of Atrial Septal Defect.

Background Although the transcatheter closure of an atrial septal defect was introduced as the treatment of choice many decades ago, the device neoendothelialization in humans is not well understood. We wanted to determine the presence of device NE using cardiac computed tomography angiography and evaluate risk factors. Methods Between January 2005 and February 2021, we retrospectively reviewed 164 devices of 112 patients on cardiac computed tomography angiography. We investigated device form, contrast opacification within the device that distinguished device NE, and device-related thrombosis or vegetation. According to the postprocedural period, the risk factor analysis of major adverse cardiovascular events and incomplete NE was performed. The device diameter was the only significant factor of incomplete NE and major adverse events, according to a risk analysis. Incomplete NE of atrial septal defect devices was identified on cardiac computed tomography angiography in significant amounts after 6 months of the procedure.

Dynamic assessment of coronary artery during different cardiac cycle in patients with coronary artery disease using coronary CT angiography.

Introduction To determine the period of measuring maximum diameters for coronary artery disease and coronary stenosis at the plaque, it's important to determine the time of measuring maximum diameters required for coronary artery disease. Methods This retrospective review examined the records for 208 consecutive patients who underwent coronary computed tomography angiography. In ten cardiac cycles, the stenosis rate of the affected vessels was determined by the cross-sectional area and diameters of the left main coronary artery's left anterior descending branch, left circumflex branch, and right coronary artery. Conclusion The maximum coronary artery stenosis rate for patients with CAD was at 65% during the 5% phase and the maximum value of coronary artery opening were at 45%-55%, which were selected for the appropriate measurement and analysis by CTA.
