Dynamic Ventricular Dyssynchrony

Left ventricular dyssynchrony and functional mitral regurgitation: two dynamic conditions.

A 30-year-old-man was admitted to the hospital in NYHA class IV without any medical treatment. The coronary arteries were normal. Left ventricular (LV) ejection fraction (EF) was 30%, mean capillary wedge pressure was 38 mmHg. The QRS duration was 120 ms. Myocardial biopsy revealed signs of idiopathic cardiomyopathy without inflammatory infiltration. The patient was treated by lisinopril, carve...

Right Ventricular Pacing and Mechanical Dyssynchrony

Dynamic relationship of left-ventricular dyssynchrony and contractile reserve in patients undergoing cardiac resynchronization therapy.

AIMS Contradicting reports have been published regarding the relation between a dobutamine-induced increase in either cardiac dyssynchrony or left-ventricular ejection fraction (LVEF) and the response to cardiac resynchronization therapy (CRT). Using apical rocking (ApRock) as surrogate dyssynchrony parameter, we investigated the dobutamine stress echocardiography (DSE)-induced changes in left-...

Is Dynamic Left Ventricular Dyssynchrony a Novel Surrogate Marker in the Patient with Hypertension?

Recently, dynamic left ventricular dyssynchrony (LVD) using exercise echocardiography (ExE) become a promising method in many cardiovascular disease, because it can unveil the pathophysiology, can predict the prognosis and also would be a possible surrogate marker in the treatment monitoring. Especially in the field of cardiac resynchronization therapy, it would be a useful tool for patient sel...
