Permanent atrial fibrillation and pulmonary embolism in elderly patients without deep vein thrombosis: is there a relationship?

Background And Aim: Permanent Atrial Fibrillation (pAF) is associated with increased risk of embolic complications. The relationship between pAF and pulmonary embolism (PE) has not been extensively investigated in elderly patients. Here, we aim at verifying whether pAF is associated to an increased risk of PE in a cohort of elderly patients with and without Deep Vein Thrombosis (DVT).

Progression of coronary artery calcification and cardiac events in patients with chronic renal disease not receiving dialysis.

We tested for the presence of coronary calcifications in patients with chronic renal disease not on dialysis and studied its progression in 181 consecutive non-dialyzed patients who were followed for a median of 745 days. Coronary calcifications (calcium score) were tallied in Agatston units by computed tomography, and the patients were stratified into two groups by their baseline calcium score (100 U or less and over 100 U). Survival was measured by baseline calcium score and its progression.

Right coronary artery arising from pulmonary trunk: assessment with conventional coronary angiography and multislice computed tomography coronary angiography.

We present a case of a 59-year-old man who was admitted to the hospital because of atypical chest pain and dyspnea. Conventional coronary angiography showed an anomalous origin of the right coronary artery from the pulmonary trunk. The patient underwent multislice computed tomography in order to clarify the origin and course of the anomalous vessel.

[Anomalous origin of the circumflex artery from the right aortic sinus: assessment with conventional coronary angiography and multislice computed tomography].

Anomalous origin of the circumflex coronary artery from the right sinus of Valsalva is the most common coronary anomaly. This anomaly is thought to be of little clinical significance without the presence of severe narrowing of the vessel. A 43-year-old woman was referred to our institution for evaluation of atypical chest pain and equivocal results of the exercise stress test.

Usefulness of multislice computed tomography to assess patency of coronary artery stents versus conventional coronary angiography.

Background: The aim of the present study was to assess the in-stent restenosis and occlusion of coronary artery stents by multislice computed tomography (MSCT) compared with conventional coronary angiography in patients with atypical chest pain and not practicable/non-conclusive stress test.

Methods: Between December 2004 and March 2006, 81 patients were scheduled and of these 72 (65 men, mean age 61 years) with 90 stents underwent MSCT angiography using a 16-slice scanner, Toshiba Aquilion 16, 8-12 months after stent placement.

Results: Of the 90 stents, 71 (79%) could be assessed and 19 (21%) were excluded because the image quality at the stent level was incompatible with diagnostic assessment.

Ogilvie's syndrome (acute colonic pseudo-obstruction): review of the literature and report of 6 additional cases.

Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002.
