Microvascular Obstruction After Radiofrequency Ablation of Ventricular Tachycardia: Comprehensive Evaluation by Magnetic Resonance Imaging and Computed Tomography

Magnetic resonance imaging performed 2 days after the procedure demonstrated severe hypokinesia in the inferior segments with hypoperfusion at rest (D, arrows; Online Videos 1 and 2) and "doughnut-like" delayed gadolinium enhancement pattern in these segments (E, arrows), specific to micro...

Zusammenfassung:Magnetic resonance imaging performed 2 days after the procedure demonstrated severe hypokinesia in the inferior segments with hypoperfusion at rest (D, arrows; Online Videos 1 and 2) and "doughnut-like" delayed gadolinium enhancement pattern in these segments (E, arrows), specific to microvascular obstruction.
