situazione acuta e grave

Acute tamponade

Acute Tamponade

Occurs due to rupture of the heart or aorta, trauma, or as a complication of catheter or pacemaker procedures

Acute cardiac tamponade is generally sudden in onset, may be associated with chest pain and dyspnea, and is life-threatening if not promptly treated. The central venous pressure is typically markedly elevated, while hypotension is common due to the decline in cardiac output. The heart sounds are often muted.

Subacute tamponade

Subacute Tamponade

Occurs due to neoplasm, uremia, or idiopathic pericarditis

Patients may be asymptomatic or may complain of dyspnea, chest discomfort or fullness, peripheral edema, fatiguability, or other symptoms referable to increased filling pressures and limited cardiac output.

The physical examination may reveal hypotension with a narrow pulse pressure, reflecting the limited stroke volume. However, patients with preexisting hypertension may remain hypertensive.

Critical tamponade is a form of cardiogenic shock,

and the differential diagnosis may initially be elusive.

Since most symptoms are nonspecific, tamponade

must be suspected in many contexts — for

example, in patients who have wounds of the chest

or upper abdomen and hypotension or in those who

have hypotension preceded by symptoms of an inciting

pericardial disease, such as chest discomfort

and pleuritic pain.

Polso paradosso

First described by Kussmaul in 1873 as a palpable decrease or absence of the radial pulse during inspiration.

Central venous pressure

Central Venous Pressure

Kussmaul’s Sign

venous return increases with inspiration and a high right atrial pressure resists filling resulting in an increased JVP

Sindromi costrittive pericardiche

Place the patient in a position of comfort and conduct manometric studies during baseline respiration.

Raise sphygmomanometer pressure until Korotkoff sounds disappear.

Lower pressure slowly until first Korotkoff sounds are heard during early expiration with their disappearance during inspiration.

Record this pressure.

Very slowly lower pressure until Korotkoff sounds are heard throughout the respiratory cycle with even intensity.

Record this pressure.

The difference between the two recorded pressures is the Pulsus Pardoxus.

Significant pulsus paradox is greater than or equal to 10% of the pressure at which all Korotkoff sounds are heard with even intensity.

Palpating pulsus paradoxus


Severe pulsus paradoxus can easily be palpated in the radial, brachial, or femoral pulses as a weakening or disappearance of the pulse during inspiration (which is best observed by watching or palpating the rise and fall of the chest)

Measuring pulsus paradoxus


An important clinical skill for following patient is the ability to estimate the severity of pulsus paradoxus:

Using a sphygmomanometer in the standard fashion but deflate the cuff more slowly than usual

During deflation, the first Korotkoff sounds are audible only during expiration, but with further deflation, Korotkoff sounds are heard throughout the respiratory cycle.

The difference between the systolic pressures quantifies pulsus paradoxus

Do not instruct the patient to breathe deeply during this evaluation. This can influences the severity of the pulsus

Significance of pulsus paradoxus in tamponade


Pulsus paradoxus precedes severe hemodynamic deterioration

When pulsus paradoxus is detectable in cardiac tamponade, the tamponade is at least moderate in severity

Almost all patients with pulsus paradoxus from tamponade need to have pericardial fluid removed

Evaluation of the inferior vena cava

Evaluation of the inferior vena cava

The central blood volume and the filling pressure of the RV can be estimated by measuring the size of the IVC and its response to respiration

Normally, the vena caval diameter will be < 17 mm, and will decrease by > 5 mm during inspiration. The negative pressure exerted by thoracic inspiratory expansion is of a magnitude similar to the mean RA and RV diastolic pressure

With  central blood volume and right heart filling pressure, the IVC becomes dilated > 20 mm, and the ability of an inspiratory effort to collapse the vessel is lost

"halo sign” - separation of the entire pericardium by a small fixed space

If the myocardium appears to pull the pericardium without altering the small echo-free separation of these layers, adhesion is suspected in the area examined

best places to look for abnormal motion of the myocardium relative to the pericardium is anterior to the right ventricular outflow tract or at the lateral apex in the four chamber view

amyloidosis is most likely to simulate constrictive pericarditis

Digoxin should be avoided in patients with cardiac amyloidosis because of enhanced susceptibility to digoxin toxicity

Echocardiography may reveal thickening of the myocardium and varying degrees of systolic ventricular dysfunction.

Doppler echocardiographic analysis may demonstrate evidence of abnormal diastolic filling patterns and elevated venous pressure

The ECG may show conduction system disease or low voltage, in contrast to the increased voltage seen with ventricular hypertrophy
