Name of the Procedure:

Pericardiocentesis

• Common names: Percardial tap
• Medical terms: Pericardiocentesis

Summary

Pericardiocentesis is a medical procedure that involves inserting a needle into the pericardial sac surrounding the heart to remove excess fluid. This excess fluid can accumulate due to various medical conditions and can compromise heart function if not treated promptly.

Purpose

• Medical condition/problem: Fluid accumulation in the pericardial sac (pericardial effusion) that can lead to cardiac tamponade.
• Goals: To relieve pressure on the heart, improve cardiac function, and prevent complications such as cardiac tamponade and heart failure.

Indications

• Symptoms of cardiac tamponade such as chest pain, difficulty breathing, fast heart rate, and low blood pressure.
• Diagnosed pericardial effusion through imaging tests like echocardiography.
• Rapidly accumulating or symptomatic pericardial effusion.

Preparation

• Pre-procedure instructions: Patients may be advised to fast for several hours before the procedure.
• Diagnostic tests: Echocardiography is typically done to confirm the presence of pericardial effusion, assess its size, and guide the needle placement.

Procedure Description

1. The patient is positioned, usually lying flat or slightly inclined.
2. Local anesthesia is administered to the site where the needle will be inserted.
3. An echocardiogram (ultrasound of the heart) is used to guide the needle into the pericardial sac.
4. A long, thin needle is inserted through the chest wall and into the pericardial sac.
5. Fluid is aspirated (drawn out) with a syringe and may be sent for laboratory analysis.
6. A catheter may be left in place temporarily to allow continuous drainage if needed.

Tools/Equipment: Echocardiogram machine, needles, syringes, and potentially a catheter for continuous drainage.

Duration

The procedure typically takes about 30 to 60 minutes, depending on the complexity and amount of fluid to be drained.

Setting

Pericardiocentesis is usually performed in a hospital setting, such as a cardiac catheterization lab or an intensive care unit (ICU).

Personnel

• Cardiologist or cardiothoracic surgeon
• Nurses
• Ultrasound technician
• Occasionally, an anesthesiologist if sedation is needed

Risks and Complications

• Common risks: Bleeding, infection, puncture of the heart or lungs.
• Rare risks: Injury to the heart muscle, arrhythmias (irregular heartbeats), air embolism.

Benefits

• Expected benefits: Rapid relief of symptoms, improved cardiac function, and prevention of complications related to pericardial effusion.
• Timeline: Benefits are usually realized immediately after the fluid is drained.

Recovery

• Post-procedure care: Monitoring in a hospital setting for a few hours to ensure there are no complications; pain management as needed.
• Recovery time: Most patients recover quickly, often within a day. Avoid strenuous activities for several days.
• Follow-up: A follow-up echocardiogram may be scheduled to ensure no re-accumulation of fluid.

Alternatives

• Other treatment options: Management with medications (e.g., anti-inflammatory drugs) if the pericardial effusion is less severe.
• Pros and cons: Medication may be less invasive but can take longer to be effective, whereas pericardiocentesis provides immediate relief.

Patient Experience

• During the procedure: Patients may feel pressure or discomfort at the needle insertion site. Sedation can be used to minimize discomfort.
• After the procedure: Some soreness or mild chest pain may be experienced, which is usually manageable with pain medications.
