The impact of predilatation (Pre-Dil) on prosthesis hemodynamics and clinical outcomes of subjects who underwent transcatheter aortic valve implantation (TAVI) with a self-expanding prosthesis remains unclear. Two thousand seven hundred twenty-one subjects from the extreme- and high-risk CoreValve Continued Access Study (CAS) were included in the analysis. Subjects who underwent Pre-Dil before TAVI were compared with subjects who underwent TAVI without Pre-Dil. Clinical outcomes included death, stroke, myocardial infarction, acute kidney injury, and new permanent pacemaker implantation...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to aortic valve replacement. However, critical cardiovascular collapse can occur during the procedure for various reasons. CASE PRESENTATION: A 90-year-old man with severe aortic stenosis and left circumflex artery stenosis developed acute torrential mitral regurgitation (MR) during TAVR. The valve deployment process induced left ventricular dyssynchrony due to left bundle-branch block and myocardial ischemia in the left circumflex artery region with torrential MR...

Stress-induced heart failure, also known as Broken Heart Syndrome or Takotsubo Syndrome, is a phenomenon characterized as rare but well described in the literature, with increasing incidence. While more commonly associated with postmenopausal women with psychiatric disorders, this entity is found in the postoperative patient. The nonischemic cardiogenic shock manifests as biventricular failure with significant decreases in ejection fraction and cardiac function. In a review of over 3000 kidney and liver transplantations over the course of 17 years within two transplant centers, we describe a series of 7 patients with Takotsubo Syndrome after solid organ transplantation...

Coarctation of the aorta has been associated with increased thoracic aortic stiffness in adolescents and young adults. However, the effects of different therapeutic strategies on aortic stiffness in a young population is unknown. This study aimed to non-invasively assess aortic stiffness between different repair or intervention strategies in patients with coarctation of the aorta. Forty-nine coarctation patients who underwent either surgery (n = 26), balloon angioplasty (n = 14), or stent implantation (n = 12), and 26 age- and size-matched normotensive healthy controls underwent evaluation of thoracic aortic stiffness and flow hemodynamics via phase-contrast cardiac magnetic resonance...

INTRODUCTION: The usefulness of carbon dioxide (CO2 ) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO2 gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO2 DSA (B-CO2 DSA) as an improved CO2 DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO2 DSA and B-CO2 DSA...

The activity of glucagon-like peptide 1 (GLP-1R) is essential for preventing restenosis following vascular injury; however, the mechanism of dysfunctional GLP-1R glycosylation and ways to enhance the activity of GLP-1R on vascular surfaces in diabetic patients are poorly understood. In the present study, we investigated the N-glycosylation level and role of stress-associated endoplasmic reticulum protein 1 (SERP1) in preventing restenosis following carotid injury in diabetic rats. Our results showed that N-glycosylation levels in both rat aortic endothelial cells (RAOECs) and rat vascular smooth muscle cells (VSMCs) decreased gradually following glucose treatment in a concentration dependant manner...
