Association between asymptomatic carotid atherosclerosis and degenerative aortic stenosis.

2012

OBJECTIVE: Degenerative aortic stenosis shows similarities with atherosclerosis. To confirm the hypothesis that aortic stenosis is an "atherosclerosis-like" disease, we investigated the association between degenerative aortic stenosis and atherosclerosis of carotid arteries. METHODS: We studied 270 consecutive patients, 135 with degenerative aortic stenosis (trans-aortic peak velocity ≥ 2 m/sec) and other 135 subjects without aortic valve disease. All patients underwent echocardiography and ultrasound scan of the supra-aortic trunks to assess the presence of plaque and/or intima-media thickening (IMT). RESULTS: Atherosclerosis of carotid arteries (IMT and plaque) was significantly more freq…

The PFO anatomy evaluation as possible tool to stratify the associated risks and the benefits arising from the closure

2010

Aims According to the current guidelines, the patent foramen ovale (PFO) is still considered a qualitative factor and, as a consequence, its closure is recommended just on the basis of its ‘presence’. Methods and results In the year 2008, we evaluated 25 patients (mean age 62.7) with acute cerebrovascular event and 92 patients (mean age 27.3) suffering from migraine with aura. No PFO was reported in 79 patients. A venous-to-arterial circulation shunt had been shown in 38 patients (29 subjects with migraine and 9 subjects with prior stroke). According to the number of microbubbles arrived during the Valsava manoeuvre, we found: 25 small PFO, 6 moderate PFO, and 6 severe PFO. In the baseline …

takotsubo cardiomiopathy after acute diarrhea

2010

Takotsubo cardiomyopaty is a recently described syndrome characterized by transient left ventricular dysfunction, mimicking an acute coronary syndrome and usually precipitated by a physical or emotional stress. We report the first case of Takotsubo cardiomyopathy after acute diarrhea in a man. It may be argued that severe diarrhea in predisposed individuals may cause an acute stress resulting in increased sympathetic activity leading to this syndrome. Probably the relationship between the adrenergic system and the heart is more complex than general thought and the stimuli which favor an autonomic imbalance and precipitate the syndrome are very disparate in clinical practice.

Patent Foramen Ovale and Thromboembolic Complications

2010

The foramen ovale, an atrial septal defect which is essential in the fetal circulation, remains patent through adulthood in approximately 25% of the general population and so it represents the most common persistent abnormality of fetal origin. Patent foramen ovale (PFO) allows interatrial right-to-left blood shunting during those periods of the cardiac cycle in which the right atrial pressure exceeds the left one. An increasing number of pathological manifestations of PFO has been recently identified; among these, paradoxical systemic embolism, refractory hypoxemia in patients with right ventricular myocardium infarction or severe pulmonary disease, orthostatic oxygen desaturation in the r…
