Ischaemia as a cause of LVOT gradient reversal in HCM
We present the case of a previously fit 84-year-old female with long-standing systemic hypertension and the echo phenotype of hypertrophic cardiomyopathy (HCM) - asymmetrical septal hypertrophy, significant resting left ventricular (LV) outflow obstruction and mitral regurgitation (MR) secondary to systolic anterior motion (SAM) of the mitral valve. Valsalva provocation caused an increase in LV...
متن کاملPredicting LVOT Obstruction in Transcatheter Mitral Valve Implantation: Concept of the Neo-LVOT.
OUTFLOWTRACT OBSTRUCTION IS A FEAREDAND POTENTIALLY LETHAL COMPLICATION OF TRANSCATHETER mitral valve replacement (TMVR), mitral valve-in-valve (ViV), and valve-in-ring (ViR) procedures as well as implantation of transcatheter heart valves in calcific mitral valve disease. These procedures ultimately lead to elongation of the outflow tract into the left ventricle, whereas the pre-existing “nati...
متن کاملGraves Induced Reversible LVOT Obstruction
A 59-year-old male with a past medical history of obesity (BMI=31), controlled hypertension (HTN) and hyperlipidemia (HLD), presented for evaluation of new exertional dyspnea of three weeks duration. He reported difficulty climbing one flight of stairs in his house; six months ago he was able to exercise without limitations. He also complained of palpitations which he described as intermittent,...
متن کاملLeft Ventricular Outflow Tract Obstruction in Hypertrophic Cardiomyopathy Patients Without Severe Septal Hypertrophy: Implications of Mitral Valve and Papillary Muscle Abnormalities Assessed Using Cardiac Magnetic Resonance and Echocardiography.
BACKGROUND In patients with hypertrophic cardiomyopathy and left ventricular outflow tract (LVOT) obstruction, but without basal septal hypertrophy, we sought to identify mitral valve (MV) and papillary muscle (PM) abnormalities that predisposed to LVOT obstruction, using echo and cardiac magnetic resonance. METHODS AND RESULTS We studied 121 patients with hypertrophic cardiomyopathy hypertro...
متن کاملNew concepts in hypertrophic cardiomyopathies, part II.
Obstructive Hypertrophic Cardiomyopathy: Pathogenesis of the Obstruction In most patients, the hypertrophy develops initially in the septum and extends to the free walls, often giving a picture of concentric hypertrophy. In '25% of patients with familial hypertrophic cardiomyopathy (FHCM), asymmetrical septal hypertrophy leads to a highly variable pressure gradient between the apical left ventr...
