Intraventricular vortex properties in nonischemic dilated cardiomyopathy.
Vortices may have a role in optimizing the mechanical efficiency and blood mixing of the left ventricle (LV). We aimed to characterize the size, position, circulation, and kinetic energy (KE) of LV main vortex cores in patients with nonischemic dilated cardiomyopathy (NIDCM) and analyze their physiological correlates. We used digital processing of color-Doppler images to study flow evolution in...
متن کاملDIFFUSE CORONARY ARTERIAL ECTASIA WITH HYPERTROPHIC CARDIOMYOPATHY
A 40 year old male, a known case of hypertrophic cardiomyopathy, was admitted for catheterization. At catheterization and angiography, septum was hypertrophied to about 5cm and diffuse coronary artery aneurysm was revealed. We found no previous report of coronary artery aneurysm in hypertrophic cardiomyopathy.
متن کاملProphylactic defibrillator implantation in patients with nonischemic dilated cardiomyopathy.
BACKGROUND Patients with nonischemic dilated cardiomyopathy are at substantial risk for sudden death from cardiac causes. However, the value of prophylactic implantation of an implantable cardioverter-defibrillator (ICD) to prevent sudden death in such patients is unknown. METHODS We enrolled 458 patients with nonischemic dilated cardiomyopathy, a left ventricular ejection fraction of less th...
متن کاملSyncope in the patient with nonischemic dilated cardiomyopathy.
Over the past decade, syncope has become increasingly recognized as an indicator of poor prognosis in patients with nonischemic dilated cardiomyopathy (NIDCM). In several clinical series, patients with depressed ejection fraction in the absence of significant obstructive coronary artery disease who experience syncope have been shown to be at high risk for sudden death with a corresponding incre...
متن کاملcomparison of benefits from cardiac resynchronization therapy between patients with ischemic cardiomyopathy and patients with idiopathic dilated cardiomyopathy
background: cardiac resynchronization therapy (crt) is an effective treatment for patients with moderate to severe heart failure. however, 20-30% of patients remain non-responders to crt. we sought to identify which patients benefit the most from crt in regard to the etiology of heart failure. methods: eighty-three consecutive patients (62 men) who had a biventricular pacemaker inserted at tehr...
