Objective Recently it has been suggested that, in patients with large patent foramen ovale （PFO） and atrial septal aneurysms （ASA）, a certain amount of left atrial （LA） dysfunction may be active as an alternate mechanism promoting arterial embolism. Following this hypothesis, elderly patients, being more susceptible to atrial chambers stiffness, should present a more severe LA dysfunction profile. We sought to evaluate the grade of LA dysfunction in elderly patients submitted to transcatheter PFO closure. Methods We retrospectively enrolled 28 consecutive patients with previous stroke （mean age 674-12.5 years, 18 females） referred to our centre for catheter-based PFO closure after recurrent stroke. Baseline values of LA passive and active emptying, LA conduit function, LA ejection fraction, and spontaneous echocontrast （SEC） in the LA and LA appendage were compared with those of 50 atrial fibrillation patients, as well as a sex/age/cardiac risk matched population of 70 healthy controls. Results Pre-closure elderly subjects demonstrated significantly greater reservoir function as well as passive and active emptying, with reduced conduit function and LA ejection fraction, when compared to healthy and younger patients. After closure in elderly patients, LAparameters did not return completely to the levels of healthy patients, whereas LA dysfunction in younger subjects returned normal. Conclusions This study suggests that elderly patients have more severe LA dysfunction than younger patients, which affects the LA remodelling after closure.

Carotid artery angioplasty and stenting in elderly patients： the advantage of being an interventional cardiologist

Objective Carotid angioplasty and stenting （CAS） has been suggested to be the procedure of choice in patients with high risk cardiovascular profile. Unfortunately, such patients are often aged with several comorbidities, such as a high prevalence of coronary artery disease, peripheral artery disease and hostile anatomy that complicate the CAS performance. We sought to evaluate the results of CAS in elderly patients, outlining the encountered challenges and the eventual proposed global cardiovascular management. Methods We retrospectively searched the database for patients 〉 65-year-old who were referred to Cardiovascular Diagnosis and Endoluminal Interventions, Rovigo General Hospital, over a 24-month period （December 2007-November 2009） for CAS. Coronary angiography and peripheral screening were performed in all patients. All eventual challenges and related solutions were analyzed. Results Totally, 160 patients were enrolled. Among which, 50 patients （31.2%, mean age 80 ~ 6.4 years） underwent CAS over a 24- month period： 24 patients （48%） had concurrent coronary artery disease （three-vessel in 7 patients, bivessel in 8 patients, single vessel in 5 patients and left main in 4 patients）; 13 patients （26%） and peripheral artery disease at the site of arterial access; 15 patients and type III aortic arch （30%）, 7 patients severe tortuosity of the common carotid artery （14%）, and 8 angulated takeoffof carotid or internal artery （16%）. Concurrent percutaneous coronary intervention was performed in 14 patients, including 3 patients with left main disease. Concurrent peripheral intervention was performed in 7 patients （ all with bilateral common or external critical disease） due to the impossibility to gain another access. Successful carotid cannulation was achieved in all patients with hostile neck. Two-wire technique has been used in 17 patients, three-wire technique in 9 patients, and four-wire technique in 4 patients. Conclusion Elderly patients submitted to CAS repres
