Use of cardiovascular computed tomography in the diagnosis and management of coarctation of the aorta.
Coarctation of the aorta is a common malformation accounting for 5% to 8% of all congenital heart defects. Although echocardiography and magnetic resonance imaging are most frequently used in the diagnosis and management of coarctation of the aorta, the role of multidetector computed tomography in congenital heart defects has been expanding and its use has been increasing over the last few years. ⋯ Knowledge of the cardiac computed tomography appearance of coarctation of the aorta and associated abnormalities is critical for accurate diagnosis and management, which includes providing information to plan surgical or percutaneous therapy. We present various forms of coarctation of the aorta on cardiac computed tomography.

Prognosis of patients undergoing emergency surgery for type A acute aortic dissection without exclusion of the intimal tear.
To investigate the prognosis after emergency surgery for acute type A aortic dissection with an unknown entry site and to identify the predictors of postoperative aortic dilatation. ⋯ The prognosis of patients without exclusion of the entry site was acceptable. Careful follow-up is needed for patients with a patent false lumen or nonexcluded entry because of the risk of aortic dilatation.

Improvement of left atrial function and left atrial reverse remodeling after minimally invasive radiofrequency ablation evaluated by 2-dimensional speckle tracking echocardiography.
The present study was aimed at demonstrating the beneficial effect of minimally invasive radiofrequency surgical ablation on left atrial remodeling using 2-dimensional speckle-tracking echocardiography. ⋯ Minimally invasive radiofrequency ablation resulted in significant left atrial reverse remodeling and significant improvement in left atrial compliance and function after restoration of sinus rhythm, as demonstrated by 2-dimensional speckle-tracking echocardiography analysis. Our findings need to be confirmed by additional and larger prospective studies.

Recombinant human hepatocyte growth factor transfection alleviates hyperkinetic pulmonary artery hypertension in rabbit models.
The study objective was to investigate the effect of recombinant human hepatocyte growth factor gene transfection via an endotracheal approach on hyperkinetic pulmonary artery hypertension rabbit models. ⋯ Human hepatocyte growth factor was expressed in rabbit lung after gene transfection via an airway approach. Recombinant human hepatocyte growth factor transfection ameliorates the pulmonary artery hypertension induced by shunt flow by promoting angiogenesis in lung tissues.
