Variability of left ventricular outflow tract gradient during cardiac catheterization in patients with hypertrophic cardiomyopathy.
OBJECTIVES This study characterizes left ventricular outflow tract (LVOT) gradient variability in patients with hypertrophic cardiomyopathy (HCM) during cardiac catheterization. BACKGROUND Management of HCM is directed by the presence and magnitude of LVOT obstruction. The magnitude and clinical impact of spontaneous variability during a single cardiac catheterization has not been described. ...
متن کاملSpontaneous variability of left ventricular outflow tract gradient in hypertrophic obstructive cardiomyopathy.
BACKGROUND Improvement in the left ventricular outflow tract (LVOT) gradient has been used as a means of assessing response to therapy in patients with hypertrophic obstructive cardiomyopathy (HOCM). To our knowledge, no data exist regarding the spontaneous day-to-day variability of the LVOT gradient in patients with HOCM. Defining the magnitude of such variability is critical to properly under...
متن کاملHigh left ventricular outflow tract gradient: Aortic stenosis, obstructive hypertrophic cardiomyopathy or both?
The authors report the case of a patient diagnosed with both hypertrophic cardiomyopathy and aortic stenosis. Due to clinical deterioration, additional investigation was performed, and a high left ventricular outflow tract gradient was identified. Correct identification of the condition causing the symptoms was challenging, and involved several imaging techniques, the contribution of transesoph...
متن کاملLeft ventricular diastolic gradient in hypertrophic cardiomyopathy☆
Systolic left ventricular (LV) gradients and diastolic dysfunction are widely studied in hypertrophic cardiomyopathy (HCM) [1,2], however diastolic gradients have never been described. A patient with HCM, mid-cavity obliteration and apical aneurysm, diagnosed by both 2D echocardiography (Fig. 1, panel A) and cardiac magnetic resonance (Fig. 1, panel B), showed color Doppler aliasing effect at m...
متن کاملEffect of Left Ventricular Outflow Tract Obstruction on Left Atrial Mechanics in Hypertrophic Cardiomyopathy
Left atrial (LA) volumes are known to be increased in hypertrophic cardiomyopathy (HCM) and are a predictor of adverse outcome. In addition, LA function is impaired and is presumed to be due to left ventricular (LV) diastolic dysfunction as a result of hypertrophy and myocardial fibrosis. In the current study, we assess the incremental effect of outflow tract obstruction (and concomitant mitral...
