Portopulmonary Hypertension (PoPH) in Chronic Liver Disease (CLD)
Expert Insights by Dr. Chetan Kalal — First DM Hepatologist of Maharashtra
What is Portopulmonary Hypertension (PoPH)?
Portopulmonary Hypertension (PoPH) is a rare but serious complication seen in patients with chronic liver disease (CLD) and portal hypertension.
In simple words — PoPH means high blood pressure in the lungs’ blood vessels caused due to long-standing liver disease.
It affects the heart-lung-liver connection, making liver transplant and patient outcomes more challenging.
Why is PoPH Important?
Dr. Chetan Kalal — a leading liver specialist and the first DM Hepatologist of Maharashtra — emphasizes that PoPH is often underdiagnosed in cirrhosis patients.
“Breathlessness in a liver patient should not always be blamed on ascites or anemia — PoPH should be ruled out early for better survival and liver transplant outcomes.” — Dr. Chetan Kalal
How Does PoPH Develop?
Liver Cirrhosis → Portal Hypertension
Hormonal & Vascular Changes → Pulmonary Artery Constriction
Increased Pulmonary Artery Pressure → Right Heart Strain
Symptoms of PoPH in Liver Patients
Unexplained Breathlessness (Dyspnea)
Fatigue on exertion
Chest discomfort
Dizziness or Fainting
Signs of Right Heart Failure (Leg swelling, Raised JVP)
How is PoPH Diagnosed?
Screening:
Transthoracic Echocardiography (2D Echo) — Look for raised pulmonary pressures (>40 mmHg)
Confirmation:
Right Heart Catheterization — Gold Standard
Pulmonary Artery Pressure > 25 mmHg confirms PoPH
Exclude other causes like COPD, Asthma, Cardiac disease
Severity of PoPH
| Severity | Pulmonary Artery Pressure (mmHg) |
|---|---|
| Mild | 25-35 |
| Moderate | 35-45 |
| Severe | >45 |
Treatment Approach
1. Medical Therapy (Before Transplant)
Pulmonary Vasodilators
Sildenafil
Bosentan / Ambrisentan
Prostacyclin analogues
Goal → Reduce Pulmonary Pressure <35 mmHg before Liver Transplant
2. Liver Transplantation
Carefully Selected Cases after Optimization
Better Outcomes if PoPH controlled pre-transplant
Prognosis
Untreated Severe PoPH → High Risk of Mortality
Treated PoPH with optimized medical therapy → Liver Transplant offers good long-term survival
Dr. Chetan Kalal’s Expert Message for Liver Patients
“PoPH is not a death sentence — Early diagnosis, right treatment, and liver transplant can offer a new life to these patients. Breathlessness in CLD must never be ignored.”
