Echocardiographic data at baseline according to right ventricular infarction class (n = 642/679, 94.5%); transthoracic (TT): 375 (58%), transesophageal (TE): 267 (42%).

^bP < 0.01 vs classes A;

^dP < 0.01 vs classes B. RV: Right ventricle; VWMA: Ventricular wall motion abnormalities; IW: Inferior wall for LV + RV; OW: Other walls; TR: Tricuspid regurgitation; AVSM: Abnormal ventricular septal motion; RVMI: Right ventricular motion index (mean ± SD); RVD/LVD: Diastolic ratio of the two ventricles; ARAWM: Abnormal right atrial wall movements; RA-DPS: Right atrium dobutamine positive stress; LVEF: Left ventricular ejection fraction.
