EpistemisHepatojugular reflux
Specialty: Cardiovascular.
Why it occurs
- Incipient or established right heart failure
- Left ventricular failure with secondary pulmonary hypertension
- Constrictive pericarditis
- Restrictive cardiomyopathy
- Tricuspid valve dysfunction with venous volume overload
Initial workup
Transthoracic echocardiogram to determine the dimensions and function of the right atrium and ventricle (TAPSE, tricuspid tissue Doppler S wave, fractional area change), look for signs of left diastolic dysfunction, and evaluate the tricuspid regurgitation gradient to estimate pulmonary artery pressure; Determination of NT-proBNP; Right heart catheterization to record baseline intracavitary pressures and during passive fluid overload maneuvers.
red flags
Persistence of positive abdominojugular reflux (sustained elevation of jugular venous pressure >3 cm of water for more than 15 seconds during sustained abdominal compression) associated with systemic arterial hypotension, severe dyspnea at rest, acral or perioral cyanosis, syncope or presyncope when performing the maneuver, or active ventricular arrhythmias on the monitor. Indicates inability of the right ventricle to handle increased venous return, requiring urgent medical evaluation.
Standard management
- Furosemide — loop diuretic of choice to deplete circulating intravascular volume and reduce hepatic and systemic venous congestion; 20 to 40 mg orally or intravenously, adjusting dose to maintain negative water balance
- Spironolactone — aldosterone antagonist to modulate the renin-angiotensin-aldosterone system and reduce visceral edema; 25 mg once daily orally, monitoring renal function and plasma potassium
- Enalapril — ACE inhibitor to reduce left ventricular afterload and relieve passive pulmonary hypertension; 2.5 to 10 mg twice daily orally, according to blood pressure tolerance
- Carvedilol (non-selective beta-blocker with alpha-1 vasodilatory action to optimize the treatment of heart failure once the patient is euvolemic; starting with a dose of 3,125 mg twice a day orally).
