Embolization of a Vascular Plug after a Year and Successful Treatment Using Two Vascular Plugs Side by Side.

• Vascular plugs used for PVL repair usually embolize late after deployment. • A low threshold for echo studies (namely TEE) is an essential part of clinical follow-up. • Redo percutaneous PVL closure should be considered in those at high surgical risk.

A multicenter, retrospective study of patients with pulmonary arterial hypertension transitioned from parenteral prostacyclin therapy to inhaled iloprost.

Pulmonary arterial hypertension (PAH) is characterized by progressive increases in pulmonary vascular resistance, leading to right heart failure and death. Guidelines recommend customization of treatment, necessitating the development of effective strategies for transitioning patients among treatments. In this study, we characterized our experience with patient transitions from parenteral prostacyclin to inhaled iloprost.

Radial Strain: Harbinger of Good News.

Introduction: We report the case of a 58-year-old woman with intracranial hemorrhage associated with stress-induced cardiomyopathy.

Results: Left ventricular dysfunction was confined to midventricular segments, and manifested with transient anterolateral wall aneurysm. Although wall motion was severely impaired in the mid-segments, an almost preserved global midventricular radial strain forecasted rapid improvement of ventricular function.

Endovascular stent graft repair of abdominal aortic aneurysms in high-risk patients: a single center experience.

Background: Endovascular stent graft (EVG) repair can be a safe alternative to open surgical repair to treat abdominal aortic aneurysms (AAA) in high-risk patients. We report our results with EVG repair in such high-risk patients at our institution.

Objectives: We wanted to show that EVG repair can be performed successfully and with a low complication rate in patients with serious comorbidities.

Endovascular intervention of aortoiliac occlusive disease in high-risk patients using the kissing stents technique: long-term results.

Endovascular intervention deploying a kissing stents (KS) technique has been used as an alternative to surgical intervention in treating symptomatic aortoiliac occlusive disease. However, the long-term results on high-risk patients are unknown. We retrospectively analyzed data on high-risk patients who underwent endovascular intervention using the KS technique at our institution.

Prospective randomized study of N-acetylcysteine, fenoldopam, and saline for prevention of radiocontrast-induced nephropathy.

The objective of this study was to compare the efficacy of N-acetylcysteine (NAC), fenoldopam, and saline in preventing radiocontrast-induced nephropathy (RCIN) in high-risk patients undergoing cardiovascular procedures. We prospectively enrolled 123 patients who were scheduled for cardiovascular procedures and had a baseline creatinine > 1.6 mg/dl or creatinine clearance of < 60 ml/min.

Homocysteine upregulates vascular cell adhesion molecule-1 expression in cultured human aortic endothelial cells and enhances monocyte adhesion.

Elevated plasma homocysteine is an independent risk factor for atherosclerosis. We hypothesized that homocysteine enhances monocyte/human aortic endothelial cell (HAEC) interactions, a pivotal early event in atherogenesis, by upregulating endothelial adhesion molecules. After incubation of cultured HAECs with reduced DL-homocysteine for up to 24 hours, adhesion of human monocytes to homocysteine-stimulated HAECs was significantly upregulated in a time- and dose-dependent fashion.
