Letter to the editor: Is “triangular QRS-ST-T waveform” a left main total occlusion marker?

We have read with great interest the article by Cipriani et al. [1] concerning the incidence and clinical implication of a special ECG pattern that they have called “triangular QRS-ST-T waveform” (TW). They observed that patients with ST-segment elevation acute myocardial infarction (STEMI) and TW had a higher risk of ventricular fibrillation, cardiogenic shock and in-hospital mortality. Furthermore, patients with TW pattern significantly more often showed a left main coronary artery (LMCA) involvement (2/4, 50% vs 2/322, 0.6%; p
