Recovering diagnostic-quality cardiac MR images from highly under-sampled data is a current research focus, particularly in addressing cardiac and respiratory motion. Techniques such as Compressed Sensing (CS) and Parallel Imaging (pMRI) have been proposed to accelerate MRI data acquisition and improve image quality. However, these methods have limitations in high spatial-resolution applications, often resulting in blurring or residual artifacts.

Cardiac tumors are a rare entity with typically unspecific symptoms. We present the case of a 43-year old female patient with epigastric pain and palpitations with a long history of diagnostics prior to discovery of an epicardial mass. The epicardial tumor with arterial vascularization from the left anterior descending artery was resected in a beating heart procedure and was found to be a lipomatous soft tissue tumor.

Current cardiac surgery has evolved to include hybrid and minimally invasive settings. In parallel, less invasive techniques have been extended to complex clinical scenarios and may prove even more beneficial in higher-risk patients. However, comorbidities and challenging anatomy still represent limitations to widespread application of this philosophy.

This report presents the case of a 66-year-old man with acute torrential aortic insufficiency after a Ross procedure 20 years earlier, a biologic aortic valve replacement 16 years earlier, and a transcatheter valve-in-valve 4 years earlier. He underwent third-time sternotomy, revealing that the pulmonary autograft was heavily calcified and frozen to the homograft. The previous transcatheter valve-in-valve was explanted.

Background: We have developed a new hybrid warp-knit fabric for induction of in situ tissue regeneration that has shown appropriate antideterioration properties and expandability in preclinical studies. This study was performed to assess the clinical efficacy and safety of this fabric in the early postoperative period after congenital cardiac surgery.
Methods: The fabric comprises biodegradable (complete degradation period, 2-3 years) and nonbiodegradable yarns coated with cross-linked gelatin.
