Case Studies

The case studies featured below demonstrate the benefits of MTWA testing in clinical practice.

CaseSummary
MTWA in Hypertensive Cardiomyopathy "MTWA helped identify the patient’s latent arrhythmic risk and was the trigger for further evaluation which ultimately led to life-saving therapy."
Sudden Cardiac Arrest in Patient with Moderate LV Dysfunction and Positive MTWA Test
"Per current primary prevention guidelines, this patient would not have received lifesaving ICD therapy if he had not undergone an MTWA study."
Immediate Ventricular Tachycardia After Abnormal Microvolt T-Wave Alternans
"These two cases present clear clinical evidence of the dependence between abnormal MTWA and the propensity to arrhythmic events…"
Spontaneous Ventricular Tachycardia and Fibrillation in a Patient with a Positive MTWA and Negative EPS
"This report shows a patient with the characteristics of a MUSTT registry patient in which a positive TWA could be used to guide ICD therapy to improve survival despite a negative electrophysiological test."
MTWA Warns of Impending Cardiac Arrest "In this case, there were no overt signs to herald the onset of ventricular fibrillation; however, it is clear that MTWA was present in the minutes preceding the event."
