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 کاملPrimary cardiac angiosarcoma confirmed by multimodality imaging guided liver biopsy.
Primary cardiac angiosarcoma is an extremely rare malignant tumor with various clinical presentations but usually in late stage. We report a case presented with bloody pericardial effusion, in which the final diagnosis was confirmed by multiple imaging modalities such as echocardiography, computed tomography, magnetic resonance imaging and fluorine-18-fluorodeoxyglucose positron emission tomogr...
متن کاملCardiac resynchronization therapy guided by cardiovascular magnetic resonance
Cardiac resynchronization therapy (CRT) is an established treatment for patients with symptomatic heart failure, severely impaired left ventricular (LV) systolic dysfunction and a wide (> 120 ms) complex. As with any other treatment, the response to CRT is variable. The degree of pre-implant mechanical dyssynchrony, scar burden and scar localization to the vicinity of the LV pacing stimulus are...
متن کاملNuclear imaging in cardiac resynchronization therapy.
Recently, cardiac resynchronization therapy (CRT) has become implemented in the treatment of patients with severe heart failure. Although the improvement in systolic function after CRT implantation can be considerable, 20%-30% of patients do not respond to CRT. Evidence is accumulating that the presence of left ventricular (LV) dyssynchrony is mandatory for a response to CRT. Since the early 19...
متن کامل[Three-dimensional imaging in cardiac resynchronization therapy].
Cardiac resynchronization therapy improves clinical symptoms and prognosis of heart failure patients. However, it has been shown that up to 40% of patients do not respond to this therapy. Three main determinants of cardiac resynchronization therapy response have been identified: left ventricular dyssynchrony, left ventricular lead position, and extent and location of myocardial scar tissue. Two...
