HE clinical significance of a pulsating liver was emphasized by Mackenzie [1] in 1902 in relation to tricuspid stenosis . He thought that a presystolic pulsation of the liver was diagnostic of tricuspid stenosis . Subsequently, Turnbull and Weil [2] in 1911 recorded a trial liver pulsations in an eighteen year old patient with left-sided rheumatic lesion involving the mitral and aortic valves alone . In 1950 Grishman et al . [3] documented presystolic pulsations of the liver in patients with heart disease but with no tricuspid valvular lesion . The present report illustrates hepatic pulse tracings in eight patients with heart disease . These patients have (1) tricuspid stenosis, (2) tricuspid incompetence with stenosis, (3) Ebstein's anomaly, (4) cor pulmonale due to multiple pulmonary infarction, (5) pericardial effusion, (6) constrictive pericarditis, (7) atrial

septal defect and (8) myocarditis . The first three patients have tricuspid valve lesions and the last five are free from organic tricuspid valvular involvement .

T

METHOD OF RECORDING LIVER PULSATIONS Hepatic tracings were taken using a pulse wave attachment connected to the AC input jack of the general purpose amplifier of a Sanborn Twin Beam Cardiette . A funnel type cup was fitted to the other end of the pulse wave attachment . The cup was held over the liver area with a steady pressure . Care was taken to place the cup lateral to the right mid-clavic ular line to avoid epigastric pulsations transmitted from the right ventricle or abdominal aorta . A phonocardiogram was taken simultaneously for the purpose of timing the hepatic pulsations . In older patients, respiratory movements were minimized by taking the tracing during a temporary pause in inspiration or expiration . NORMAL HEPATIC PULSE

Ist

The normal liver pulse consists of an "a" and a "v" wave . (Fig . 1 .) The "a" wave is due to atrial contraction . During ventricular systole the normal hepatic pulse has a negative wave called "systolic collapse ." This is apparently due to a decrease in liver volume as the hepatic veins empty into the inferior vena cava during ventricular contraction . The "v" wave occurs in early diastole and represents increase in hepatic volume . The "a" and "v" waves occur 0 .02 and 0 .004 second later than the corresponding waves in the jugular pulse . The "c" wave normally found in jugular and in atrial pulse tracings is absent . According to Mackenzie the "c" wave of the jugular pulse is due to carotid pulsation . Grishman et al . [3] believe the impact of aortic pulsation on the superior vena cava during cardiac systole accounts for the "c" wave in the jugular pulse . The "c" wave in the atrial pulse tracing is attributed to the ballooning of the A-V valves into the atrium during ventricular systole .

Abnormal pulsations of the liver are either presystolic (atrial) or systolic in time in relation to the cardiac cycle . The accentuation of the normal "a" wave gives rise to a large presystolic or atrial liver pulse . With a normal sinus rhythm the term "presystolic" is correct . When the atria and the ventricles contract simultaneously or

almost simultaneously, as in certain types of arrhythmias, the "a" wave of the hepatic pulse may occur during ventricular systole . In the presence of atrial fibrillation, a situation in which an effective and strong atrial contraction is wanting, the "a" wave is absent . For these reasons, "atrial" is preferable to "presystolic" in describing the "a" wave of the hepatic pulse . A positive systolic wave in the liver pulse is always abnormal . It represents tricuspid incompetence if an "a" wave produced by an arrhythemia is excluded . This positive wave is called systolic wave "en plateau ." It is due to retrograde transmission of a pulse wave resulting from right ventricular contraction . The extra load on the right atrium and the great veins provided by AMERICAN JOURNAL OF MEDICINE



I .ivci Pulsatioun ill Hcait lliseasc the regurgitant blood may be an additional factor in the genesis of this wave . AtrialPulsations . Conditions producing prominent atrial pulsation of the liver may be due to systolic or to diastolic overloading of the right atrium or both . (Table 1 .) The entrance of both superior and inferior venae cavae into the right atrium is not protected by any competent valve structure . Refiux of dye into the great veins during the rapid injection of dye into the right atrium is commonly seen in angiocardiograms or cineangiocardiograms . The retrograde transmission of the pressure wave from a strong right atrial contraction (or from the contraction of the left atrium transmitted through an atrial septal defect) down the inferior vena cava to the liver produces the prominent "a" wave in these conditions. Clinically, anatomic obstruction to right atrial outflow is seen in congenital tricuspid atresia in its complete form . An atrial septal defect must exist to sustain life . Partial obstruction is found in tricuspid stenosis, commonly acquired and rarely congenital (Case I) . Usually acquired tricuspid stenosis is part of a multivalvular rheumatic involvement . Differentiation between congenital tricuspid stenosis and atresia is now possible during life by cineangiocardiography ]4] . Since both these conditions show prominent "a" waves, the hepatic tracing adds no further help in the differential diagnosis . However, a hepatic pulse tracing may be helpful in ruling out congenital tricuspid incompetence . Certain disturbances in cardiac rhythm give rise to a prominent "a" wave in thejugular pulse as well as in the hepatic pulse tracing . Examples of such arrhythemias are complete A-V block or A-V dissociation, atrial flutter or atrial tachycardia with A-V block, double tachvcardias and some types of nodal rhythm . Large "a" waves are produced when atrial contraction occurs simultaneously with ventricular systole . In this instance the A-V valves are closed temporarily because of ventricular contraction . The force of atrial contraction therefore can he propagated only retrograde to the jugulars and to the liver . In pure pulmonic stenosis (ventricular septum intact) prominent "a" waves are commonly seen in the jugular pulse . In fact if pulmonary stenosis is suspected and no prominent "a" wave is visible in the jugular vein an associated ventricular septal defect must he considered . FEURUARY

Right ventricular pressure is increased in pulmonary stenosis and pulmonary hypertension (Case iv) . This increase in right ventricular pressure raises the resistance to outflow of the right atrium . Figure 10 shows a jugular pulse tracing in a patient with pure pulmonic stenosis . Catheterization data did not reveal any evidence of a shunt . The diastolic filling of the right ventricle is restricted in pericardial effusion (Case v) and in constrictive pericarditis (Case vi) . It is possible that extracardiac masses pressing on the ventricular chambers may produce the same effect . The third sound called "protodiastolic knock" heard in some cases of constrictive pericarditis has been related to the early diastolic check to ventricular filling by the calcified pericardial shell . The third heart sound coincides with the early diastolic dip in a ventricular pressure tracing . Figure 6 shows the third sound in the phonocardiogram above the hepatic pulse curve before operation . After pericardiectomy the third sound disappeared and the hepatic pulse tracing returned to normal . Ebstein's anomaly (Case 3) presents an interesting congenital malformation of the tricuspid valve . The anterior and posterior leaflets are

fused and displaced downward into the cavity of the right ventricle . The right atrium becomes greatly enlarged at the expense of the right ventricular chamber . Frequently there is an associated atrial septal defect or a patent foramen ovale . The reduction in size of the cavity of the right ventricle limits ventricular filling in this condition . The shunt at the atrial level may he bidirectional, hence the absence of cyanosis does not rule out the diagnosis of Ebstein's anomaly . Diastolic overloading of the right atrium as a result of a left to right shunt at the atrial level (Case vii) increases the work load of the right atrium . This produces a strong atrial contraction . Myocardial weakness due to myocarditis (Case vnt) imposes a condition of relative diastolic overloading of the ventricles . The right ventricle, being the weaker ventricle, may fail earlier than the left . The decreased output of the former may spare the latter . When right ventricular failure develops, the end diastolic pressure in the right ventricle becomes elevated and the right atrial pressure also rises . In combined left and right ventricular failure the situation is more complex . A combination of

factors, including increase in circulating blood volume, may be at work . Half of the patients reported by Grishman et al . [3] were in congestive heart failure of moderate to severe degree . In this report severe congestive heart failure was present in Cases n and vin . Systolic Pulsations. Systolic pulsation of the liver is classically found in tricuspid incompetence, functional or organic . Lottenhach and Shillingford [5] have verified tricuspid incompetence at autopsy in ten patients with congestive heart failure whose mean venous pressure during life was greater than 8 mm . Hg . They postulated that tricuspid incompetence was produced first, by the dilated right ventricle pulling down the chordae attached to the edge of the valve, and second by the general dilatation of the valve ring . According to Hellman [6] the tricuspid valve is anatomically prone to incompetence in comparison with the mitral valve . It is probably true that functional tricuspid incompetence does occur in most cases of frank congestive heart failure . Organic tricuspid incompetence is usually due to rheumatic valvulitis . Incompetence almost always accompanies rheumatic tricuspid AMERICAN JOURNAL OF MEDICINE

Arrows indicate systolic wave "en plateau ." Aerial wave (a) is present . Compare with Figure 3 . (See text.) stenosis (Case n) . Congenital tricuspid incompetence is rare [7] . Both organic and functional tricuspid incompetence are characterized by a systolic wave "en plateau" in the hepatic pulse tracing . The differentiation between the two may prove difficult at times . Usually in functional tricuspid incompetence the plateau wave comes early in systole ; it may fuse with the downstroke of the "a" wave . In organic tricuspid incornpetence the "en plateau" wave has a delayed onset with a gradual rise and fall . The reason for this is the fact that acquired organic tricuspid incompetence usually accompanies stenosis of the valve as well . Figure 3 shows the hepatic FEBRUARY 1961

pulse tracing obtained in Case n . Typically, the plateau wave is delayed in onset ; the rise is gradual and the fall is slow . Recently, Terry [8] described a new physical sign in tricuspid incompetence called "coupled hepatic pulsation ." He found that ventricular extrasystoles may be helpful in distinguishing intrinsic hepatic pulsations due to tricuspid incompetence from hepatic pulsations transmitted from the abdominal aorta . By holding one hand over the liver and the other over a peripheral artery one will notice that in the presence of a ventricular extrasystole no pulse will he felt in the peripheral artery . However, a pulsation will be felt over the liver if tricuspid

incompetence exists . This sign becomes more obvious in coupled rhythm due to ventricular extrasystoles . Correct timing of hepatic pulsations may be difficult by palpation and/or inspection alone . In the presence of a tachycardia the difficulty is magnified . In addition, the weaker atrial (presystolic) pulsation may not be appreciated by the palpating hand as a pulse wave separate from the usually stronger systolic pulsation, even with a normal sinus rhythm . In atrial fibrillation the "a" wave is absent and the systolic wave "en plateau" becomes more pronounced because tricuspid incompetence is increased . In Figure 3 the "a" wave is absent because the tracing was taken when the patient was in atrial fibrillation . Figure 11 is a tracing obtained from another patient with tricuspid stenosis with incompetence . Sinus rhythm and the "a" wave are present . Again the systolic wave "en plateau" is delayed in onset . By taking a hepatic pulse tracing, timing of liver pulsations is rendered easy and accurate . Recent advances in tricuspid valve surgery [9,10] have made correct timing of hepatic pulsations of more than academic interest . Consideration of a patient for possible surgery

of the tricuspid valve demands precise diagnosis of the valvular lesion-stenosis, incompetence, or both . In this regard, a hepatic pulse tracing may be helpful in corroborating the findings in the catheterization of the right heart and in cineangiocardiography [4] . A palpable liver is one of the cardinal signs of congestive heart failure . Mechanical obstruction to venous return of the right heart, as found in tricuspid valvular disease and in pericarditis, may produce hepatic enlargement with or without palpable or visible pulsation, edema or ascites in the absence of actual failure of the myocardium . Experimental studies [11,12] have demonstrated increased secretion of aldosterone in dogs with thoracic inferior vena cava constriction . An increase in aldosterone secretion may well be a factor in the production of liver engorgement, edema and ascites in tricuspid and pericardial disease . It is clinically important that the mere presence of these signs should not be construed hurriedly as evidence of congestive

heart failure and, therefore, an indication for digitalization . Conversely, in a patient (usually a female) with known rheumatic heart disease involving the mitral and/or aortic valve, persistence of signs of right-sided heart failure should call attention to tricuspid valvular involvement . SUMMARY

The clinical importance of pulsations of the liver in different heart conditions is summarized and the pathogenesis of these pulsations is explained . Eight case reports illustrating abnormal liver pulsations are presented . The value of correct timing of liver pulsations by taking hepatic pulse tracings is emphasized in the light of recent advances in tricuspid valve surgery REFERENCES
