Embolic Events After Computed Tomography Contrast Injection in Patients With Interatrial Shunts: A Cohort Study
Conclusion: Among patients with echocardiographic evidence of an interatrial shunt, IV CT contrast administration without an in-line filter does not increase the incidence of cardiac or neurological events.

Paradoxical Embolism in a Girl with Atrial Septal Defect After Paroxysmal Supraventricular Tachycardia Ablation
Paradoxical embolism is a kind of important pathogenesis of cardiocerebrovascular diseases. In our case, radiofrequency current catheter ablation was accomplished successfully in a 15-year-old girl who had been experiencing supraventricular tachycardia for 6 months. She presented with abrupt onset of left hemiplegia and loss of consciousness on the first postoperative day. An urgent cerebral computed tomography showed a hyperdense right middle cerebral artery. Transthoracic echocardiogram examination revealed an atrial septal defect (ASD), with the diameter measuring 39  mm.

Imaging Techniques in Percutaneous Cardiac Structural Interventions: Atrial Septal Defect Closure and Left Atrial Appendage Occlusion
Publication date: Available online 25 June 2016 Source:Revista Española de Cardiología (English Edition) Author(s): Antonio Rodríguez Fernández, Armando Bethencourt González Because of advances in cardiac structural interventional procedures, imaging techniques are playing an increasingly important role. Imaging studies show sufficient anatomic detail of the heart structure to achieve an excellent outcome in interventional procedures. Up to 98% of atrial septal defects at the ostium secundum can be closed successfully with a percutaneous procedure. Candidates for this type of procedure can be identified through a ...

Cardiovascular diseases in patients 65 years and younger with non-cardiogenic stroke.
CONCLUSIONS: Aetiologically heterogeneous stroke and cardiogenic stroke are the most commonly observed among young stroke patients. Cardiomyopathy and atrial fibrillation are the most common sources of cerebral embolism in young patients with cardiogenic stroke. Nearly 1/5 of patients with a non-cardiogenic stroke have congenital or acquired structural changes in the heart. PMID: 27279848 [PubMed]

The Role of Computed Tomography Angiography in Patients Undergoing Evaluation for Minimally Invasive Cardiac Surgery: An Early Program Experience
Conclusions: Computed tomography angiography is of fundamental importance in evaluating patients for MICS. It can identify calcified regions that make for threatening catheter passage with subsequent retrograde arterial perfusion. Abnormalities of the arterial tree are identified. The use of CTA-guided patient selection can thus avoid major perioperative complications.

Early neurological complications after transcatheter closure of atrial septal defect with nitinol wire mesh occluder.
Abstract Atrial septal defect (ASD) was closed percutaneously in an 18-year-old boy with a 27 mm nitinol wire mesh occluder according to standard procedures. Three hours after the procedure, he presented anxiety attacks, aggression, a vacant stare and a verbal/speaking disorder. Small ischaemic stroke localised in the right temporal/parietal region of the central nervous system was confirmed by computed tomography examination. Activated partial thromboplastin time was then 54 s despite continuous heparin infusion. Heparin dose was increased and symptomatic treatment was introduced (mannitol, furosemide, propofol, ...
