Vasopressin role in hypertrophic obstructive cardiomyopathy post-cardiac surgery: A case report

Figure 1 Electrocardiogram on admission. Paced rhythm due to complete atrioventricular block.

Figure 2 Onset of hypoxemia. A: Chest X-ray demonstrates pulmonary congestion; B: Resolution of pulmonary congestion on chest X-ray following diuresis and vasopressin.

Figure 3 Hypertrophic left ventricle. A: Interventricular septum dimension in end-diastole = 1.4 cm; B: Plethoric inferior vena cava; C: Systolic anterior motion of mitral valve with severe mitral regurgitation and left ventricular outflow tract obstruction.

Figure 4 Five-chamber view on transthoracic echocardiographic. A: Left ventricular outflow tract peak gradient 71 mmHg (during noradrenaline infusion); B: Resolution of left ventricular outflow tract gradient after vasopressin infusion.
