Masked Hypotension due to Elevated Venous Pressure in a Patient with Complex Adult Congenital Heart Disease

Table 1

Hemodynamic data obtained during right heart catheterization and bedside pulmonary artery catheter measurements.

	Without dopamine	With dopamine at 9 mcg/kg/min
MAP (mmHg)	45	94
CVP (mmHg)	14	20
Cardiac output (L/min)	9.05	7.46
CI (L/min/m^2)	3.85	3.12
SVR (DS/cm^5)	256	793
PAP (mmHg)	33/11 (21)	40/19 (27)
PCWP (mmHg)	16	20
PVR (DS/cm^5)	35	75
RAP (mmHg)	12	n/a^#
RVP (mmHg)	42/4 (12)	n/a^#
LVP (mmHg)	113/-3 (16)	n/a^#

Cardiac output calculated using Fick’s formula. ^#Direct measurements of right atrial pressure, right ventricular pressure, and left ventricular pressure were unable to be obtained using the bedside pulmonary artery catheter. CI = cardiac index; CVP = central venous pressure; MAP = mean arterial pressure; PAP = pulmonary artery pressure; PCWP = pulmonary capillary wedge pressure; SVR = systemic vascular resistance; RAP = right atrial pressure; RVP = right ventricular pressure; LVP = left ventricular pressure.
