Cardiac resynchronization therapy guided by tissue Doppler
Nowadays, chronic congestive heart failure (CHF) remains a challenge despite significant progress in drug therapy. Cardiac resynchronization therapy (CRT) has revolutionized CHF treatment as a result of improved cardiac function based on optimal drug therapy [1, 2]. However, approximately 18% to 32% of patients who have undergone CRT do not experience positive curative effects [3, 4]. Recent st...
متن کاملImprovement of left ventricular function after cardiac resynchronization therapy is predicted by tissue Doppler imaging echocardiography.
BACKGROUND Cardiac resynchronization therapy was shown to reverse left ventricular (LV) remodeling in patients with congestive heart failure (CHF). However, the prediction of benefit is controversial. We aimed to investigate predictive factors of LV functional recovery and reversed remodeling after biventricular pacing. METHODS AND RESULTS Forty-nine consecutive patients with CHF and a wide Q...
متن کاملWhat happens to non-responders in cardiac resynchronization therapy?
INTRODUCTION AND OBJECTIVES Left ventricular reverse remodeling (LVRR) is strongly related to the long-term prognosis of patients undergoing cardiac resynchronization therapy (CRT). The aim of this study was to assess the long-term clinical outcome of patients without LVRR at six months after CRT implantation and to determine the prognostic impact of clinical response in this population. METH...
متن کاملVentricular arrhythmias in super-responders to cardiac resynchronization therapy.
INTRODUCTION AND OBJECTIVES Cardiac resynchronization therapy is associated with improved quality of life and reduced morbidity and mortality in patients with severe ventricular dysfunction and wide QRS. However, its role in the reduction of ventricular arrhythmias is more controversial. METHODS We compared the incidence of ventricular arrhythmias in patients who were undergoing cardiac resyn...
متن کاملCardiac dysfunction in acromegaly: evidence by pulsed wave tissue Doppler imaging.
OBJECTIVE To verify whether the accuracy of data on myocardial function provided by pulsed-wave tissue Doppler imaging (PWTDI), a new echocardiographic application that allows quantitative measurements of myocardial wall velocities, could help towards a better understanding of the natural history of acromegalic cardiomyopathy. DESIGN Eighteen patients with active acromegaly (ten men and eight...
