Left Ventricle Diastolic Function Evaluation in Patients with Implanted Devices

Compared with patients without intracardiac devices, patients with implanted devices will present some inconvenience in diastolic dysfunction evaluation linked to dyssynchrony due to the right ventricle lead presence and atrioventricular interval optimization. Small studies provide some information about diastolic dysfunction parameters in these patients. The probability of normal diastolic function in patients with cardiac resynchronization therapy or right ventricular pacing is low because they usually present structural heart disease. The more advanced diastolic dysfunction, the more increased left ventricle filling pressure. There are no specific indications for diastolic dysfunction evaluation in patients with implanted devices. The last guidelines may be used mainly for grading diastolic dysfunction, considering the accuracy of presented parameters in this situation.
