TL;DR: In this article, the authors developed a 4D flow magnetic resonance imaging (MRI) scan and clinically available analysis protocol based on beat tracking of the cardiovascular lumen without contrast medium, which enabled measurement of the biventricular hemodynamics and energetic performance by calculating flow energy loss (EL) and kinetic energy (KE).

TL;DR: A 54-year-old Japanese woman with palpitations and wide QRS tachycardia with persistent tiredness is described in which a four-dimensional imaging tool was useful in the decision to re-operate, thus resulting in decreased energy loss and improved right ventricular function after the re-operation for tetralogy of Fallot.

TL;DR: Identification of an increased number of patients with AF, if properly treated with DOAC, ultimately leads to a reduction in the number of strokes occurred over subjects’ lifetime.

TL;DR: Although NSE PTA scoring balloon was safe, there was no significant pressure gradient improvement with NSE BPA scoring balloon compared to conventional BPA, Nevertheless, the NSE EMT scoring balloon showed effective blood-flow improvement in the case of large balloon-to-vessel ratio.

TL;DR: A 42-year-old Japanese woman referred to the authors' hospital for moderately severe pulmonary regurgitation and severe tricuspid Regurgitation after a Ross–Konno procedure developed atrial fibrillation and atrial flutter and complained of dyspnea, and a four-dimensional imaging tool can be useful in the decision of re-operation in patients with complex adult congenital heart disease.
