Right heart failure (RHF) is a complex and often underdiagnosed condition that can have significant consequences for patients. It is characterized by the inability of the right ventricle to effectively pump blood, leading to a buildup of pressure in the pulmonary circulation and a decrease in systemic blood flow. RHF can be caused by a variety of factors, including pulmonary hypertension, cor pulmonale, and left heart failure.

The symptoms of RHF can vary depending on the underlying cause, but may include:

* Shortness of breath * Fatigue * Swelling in the legs, ankles, and feet * Chest pain * Lightheadedness or dizziness * Confusion

Diagnosis

The diagnosis of RHF is based on a combination of the patient's symptoms, physical examination findings, and echocardiography. Echocardiography is a non-invasive imaging test that can provide detailed information about the structure and function of the heart.

Other tests that may be used to diagnose RHF include:

* Chest X-ray * Electrocardiogram (ECG) * Blood tests * Right heart catheterization

Management

The management of RHF depends on the underlying cause. In some cases, the underlying cause can be treated directly, which will improve the function of the right ventricle. In other cases, the management of RHF is focused on relieving symptoms and improving quality of life.

Treatment options for RHF may include:

* Medications to reduce pulmonary hypertension * Diuretics to reduce fluid retention * Oxygen therapy * Mechanical ventilation * Heart transplantation

Clinical Cases

The following clinical cases illustrate the different presentations of RHF and the challenges involved in its diagnosis and management.

Case 1

A 55-year-old man with a history of chronic obstructive pulmonary disease (COPD) presents to the emergency department with shortness of breath and swelling in his legs. He has been feeling progressively worse over the past few months, and his symptoms are now significantly impacting his quality of life.

On examination, the patient is tachypneic and has jugular venous distension. Auscultation of the lungs reveals wheezes and crackles. The patient's abdomen is distended and there is pitting edema in his legs.

An echocardiogram shows severe pulmonary hypertension and right ventricular enlargement. The patient is diagnosed with cor pulmonale, a type of RHF caused by COPD.

The patient is started on treatment with diuretics and oxygen therapy. He is also given a referral to a pulmonologist for further management of his COPD.

Case 2

A 25-year-old woman with a history of congenital heart disease presents to the clinic with fatigue and dizziness. She has been feeling increasingly tired over the past few months, and she has also been experiencing lightheadedness and dizziness when she stands up.

On examination, the patient is afebrile and has a normal blood pressure. Auscultation of the heart reveals a loud S2 heart sound. The patient's abdomen is soft and non-tender.

An echocardiogram shows a large atrial septal defect (ASD),a hole in the wall between the atria of the heart. The patient is diagnosed with RHF due to left-to-right shunting through the ASD.

The patient is referred for surgical closure of the ASD. After surgery, her symptoms improve significantly and she is able to return to her normal activities.

RHF is a complex and often underdiagnosed condition that can have significant consequences for patients. It is important for healthcare professionals to be aware of the different presentations of RHF and to be able to diagnose and manage this condition effectively.

The clinical cases presented in this article illustrate the challenges involved in the diagnosis and management of RHF. By understanding the different presentations of this condition, healthcare professionals can improve the outcomes of patients with RHF.
