A 4-chamber view with color Doppler showing the tricuspid regurgitation (TR), enlarged right atrium (RA), enlarged right ventricle (RV), compressed left atrium (LA), and compressed left ventricle (LV) before adenotonsillectomy.

Echocardiography revealed a grossly dilated right atrium and ventricle, compressed left atrium and ventricle, dilated pulmonary artery, inferior vena cava and hepatic vein, severe pulmonary hypertension (PHT), and tricuspid regurgitation grade III (Figures 1 and 2).
+ shows maximum velocity (4.51 m/sec) equivalent to the pressure gradient of 81 mmHg which indicates severe pulmonary hypertension before adenotonsillectomy.

Echocardiography revealed a grossly dilated right atrium and ventricle, compressed left atrium and ventricle, dilated pulmonary artery, inferior vena cava and hepatic vein, severe pulmonary hypertension (PHT), and tricuspid regurgitation grade III (Figures 1 and 2).
A 4-chamber view showing normal right atrium (RA), normal right ventricle (RV), normal left atrium (LA), and normal left ventricle (LV) 6 months after adenotonsillectomy.

Six and twelve months after adenotonsillectomy, echocardiography revealed normal findings indicating reversal of all cardiac alterations which were seen in the first (preoperative) and the second (six months after adenotonsillectomy, Figure 3) echocardiogram.
