Aortic dissection is a rare but potentially fatal event resulting in separation of the layers of the tunica media by ingress of blood, producing a false lumen with variable proximal and distal extension. Ascending aortic dissection is the most common catastrophe of the aorta; it is 2–3 times more common than rupture of the abdominal aorta. Mortality of(More)
Aims The aim of our study is to assess the incidence and clinical significance of right ventricular (RV) involvement in Takotsubo cardiomyopathy (TTC). Methods and results Between February 2002 and December 2005, 47 patients with TTC underwent car-diovascular magnetic resonance (CMR) at our institutions. 13 patients with delayed initial CMR were excluded.(More)
BACKGROUND Myocarditis can occasionally lead to sudden death and may progress to dilated cardiomyopathy in up to 10% of patients. Because the initial onset is difficult to recognize clinically and the diagnostic tools available are unsatisfactory, new strategies to diagnose myocarditis are needed. METHODS AND RESULTS Cardiovascular MR imaging (CMR) was(More)
BACKGROUND Enteroviruses and adenoviruses have been considered the most common causes of viral myocarditis, but parvovirus B19 (PVB19) and human herpesvirus 6 (HHV6) are increasingly found in endomyocardial biopsy samples. METHODS AND RESULTS Consequently, our aim was to evaluate the prevalence and clinical presentation of cardiac PVB19 and/or HHV6(More)
BACKGROUND Few data exist on gender-related differences in clinical presentation, diagnostic findings, management, and outcomes in acute aortic dissection (AAD). METHODS AND RESULTS Accordingly, we evaluated 1078 patients enrolled in the International Registry of Acute Aortic Dissection (IRAD) to assess differences in clinical features, management, and(More)
BACKGROUND The definition, prevalence, outcomes, and appropriate treatment strategies for acute intramural hematoma (IMH) continue to be debated. METHODS AND RESULTS We studied 1010 patients with acute aortic syndromes who were enrolled in the International Registry of Aortic Dissection (IRAD) to delineate the prevalence, presentation, management, and(More)
BACKGROUND Follow-up survival studies in patients with acute type B aortic dissection have been restricted to a small number of patients in single centers. We used data from a contemporary registry of acute type B aortic dissection to better understand factors associated with adverse long-term survival. METHODS AND RESULTS We examined 242 consecutive(More)
BACKGROUND Chronobiological rhythms have been shown to influence the occurrence of a variety of cardiovascular disorders. However, the effects of the time of the day, the day of the week, or monthly/seasonal changes on acute aortic dissection (AAD) have not been well studied. METHODS AND RESULTS Accordingly, we evaluated 957 patients enrolled in the(More)
