Role of Multimodality Imaging in Transcatheter Structural Interventions.

Cardiac imaging is the backbone for safe and optimal transcatheter structural interventions. Transthoracic echocardiogram is the initial modality to assess valvular disorders, while transesophageal echocardiogram is best to delineate the mechanism of valvular regurgitation, preprocedural assessment for transcatheter edge-to-edge repair, and for intraprocedural guidance. Cardiac computed tomography is the modality of choice for assessing calcifications, maneuvering multiplaner reconstruction of different cardiac structures, preprocedural planning for various transcatheter valve replacement, and assessing for hypoattenuated leaflet thickening and reduced leaflet motion.

Type A Aortic Dissection with Antegrade Intimointimal Intussusception.

We describe a 60-year-old man with a history of hypertension who presented to an outside emergency department with chest pain and left lower extremity numbness and weakness. Computed tomography (CT) revealed Stanford type A aortic dissection (TAAD), and he was transferred to our institution for emergent open surgical repair. Review of the outside CT showed no dissection flap in the ascending aorta and a complex flap in the proximal descending thoracic aorta consistent with complex intimal transection at the sinotubular junction and intimointimal intussusception.

Influence of Cardiac Remodeling on Clinical Outcomes in Patients With Aortic Regurgitation.

Background: Quantitative cardiac magnetic resonance (CMR) outcome studies in aortic regurgitation (AR) are few. It is unclear if volume measurements are beneficial over diameters.

Objectives: This study sought to evaluate the association of CMR quantitative thresholds and outcomes in AR patients.

Patterns of Functional Gastrointestinal Disorders Among Children in Makkah City: A Single Institutional Experience.

Background Functional gastrointestinal disorders (FGIDs) are syndromes identified based on a group of symptoms defined according to the criteria of the Rome Foundation. The most commonly observed disorders among the pediatric population are functional abdominal pain disorders and functional constipation. This study aims to identify the patterns of FGIDs among children in Makkah, Saudi Arabia.

Ventricular Septal Rupture Complicating Silent Myocardial Infarction.

A 55-year-old gentleman presented to the emergency department with shortness of breath for the past 3 days. Cardiac magnetic resonance imaging assessed intracardiac shunting and a mechanism of ventricular septal rupture (VSR), showing significant left-to-right shunting and Qp:Qs of 4:1. There was transmural myocardial infarction as well as an aneurysm at the diaphragmatic inferior wall of the left ventricle.
