Prognostic value of Doppler-derived mitral deceleration time on left ventricular reverse remodelling after undersized mitral annuloplasty.
AIMS This study was aimed at exploring the predictive value of Doppler-Derived Mitral Deceleration Time (DT) on left ventricular reverse remodelling (LVRR) in patients with chronic ischaemic mitral regurgitation (CIMR) undergoing combined undersized mitral annuloplasty (UMRA) and coronary artery bypass grafting (CABG). METHODS AND RESULTS Two hundred and fifteen patients undergoing combined U...
متن کاملShortened Doppler-derived mitral A wave deceleration time: an important predictor of elevated left ventricular filling pressure.
OBJECTIVES The aim of this study was to investigate whether a new variable of mitral inflow, A wave deceleration time, identifies patients with elevated left ventricular filling pressures. BACKGROUND In patients with an elevated left ventricular end-diastolic pressure, the increase in left ventricular pressure after atrial contraction rapidly exceeds left atrial pressure, resulting in abrupt ...
متن کاملDoppler-derived mitral deceleration time: an early strong predictor of left ventricular remodeling after reperfused anterior acute myocardial infarction.
BACKGROUND The relation between remodeling and left ventricular (LV) diastolic function has not yet been fully investigated. The aim of this study was to determine whether early assessment of Doppler-derived mitral deceleration time (DT), a measure of LV compliance and filling, may predict progressive LV dilation after acute myocardial infarction (AMI). METHODS AND RESULTS Fifty-one patients ...
متن کاملMitral flow derived Doppler indices of left ventricular diastolic function.
AIMS Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for...
متن کاملEarly mitral deceleration and left atrial stiffness.
Left ventricular (LV) filling deceleration time (DT) is determined by the sum of atrial and ventricular stiffnesses (KLA + KLV). If KLA, however, is close to zero, then DT would reflect KLV only. The purpose of this study was to quantify KLA during DT. In 15 patients, KLV was assessed, immediately after cardiopulmonary bypass, from E wave DT as derived from mitral tracings obtained by transesop...
