MCQ – 2

Infective endocarditis due to pseudomonas is mostcommonly seen with

>Intravenous drug abuse of pentazocin

>HIV patient

>Chronic steroid therapy

>Elderly with community acquired pneumonia

Explanation :

intravenous drug abuse of pentazocin [Ref Harrison 1661/e p 891]

  • Psudomonas aeruginosa infects the native heart valves of intravenous drug users as well as prosthetic heart valves.
  • Foreign materials mixed with heroin or any other opioid may cause injury to valve leaflets or mural endocardium with resulting fibrosis and an increased risk for valve infection.

Note : Pentazocine is an opioid.

MCQ – 3

A 30-year-old woman with a history of intravenous drug abuse is admitted to a hospital for rapidly progressive malaise, fever, and chills. On physical examination, subungual splinter hemorrhages and a systolic murmur are detected. Blood cultures are positive for Staphylococcus aureus. She died of myocardial infarction on her third hospital day. Which of the following was the underlying condition leading to the patient’s demise?

Acute infective endocarditis

Carcinoid heart disease

Libman-Sacks endocarditis

Nonbacterial thrombotic endocarditis

Explanation :

Infective endocarditis leads to formation of bulky and friable vegetations on the valvular leaflets.
The vegetations are composed of fibrin, neutrophils, and colonies of bacteria that cause erosion of underlying cardiac structures.
Fragments of infected vegetations may detach and cause pulmonary or systemic septic embolism.
Splinter hemorrhages in the nail bed and petechiae in skin and mucosae are also due to microscopic septic emboli.
In this case, myocardial infarction was probably due to a septic embolus in the coronary circulation.
If infective endocarditis is due to a virulent organism such as Staphylococcus aureus (a common cause of endocarditis in intravenous drug abusers), a tumultuous clinical course ensues, associated with high mortality.
With less virulent organisms, such as Streptococci viridans, Subacute infective endocarditis is the resultant clinical picture.
Subacute endocarditis arises in patients with previously malformed or damaged valves and is associated with a slower course and a better prognosis.

Also Know:
Carcinoid heart disease is caused by serotonin-producing carcinoids in the liver or lungs. Fibrosis of the endocardium ensues, affecting the right heart in the case of hepatic carcinoids and the left heart for pulmonary carcinoids. Thickening and rigidity of valvular leaflets are characteristic gross findings.
Libman-Sacks endocarditis is a non-infective form of endocarditis associated with systemic lupus erythematosus (SLE). The vegetations are small and regularly aligned along the valvular margins.
Nonbacterial thrombotic endocarditis was previously known as marantic endocarditis, being associated with debilitating conditions such as disseminated neoplasms. Increased coagulability is probably the underlying pathogenesis. The lesions are small vegetations similar to Libman-Sacks endocarditis.

MCQ – 4

Which among the following is the most common cause of acute infective endocarditis?

Staphylococcus aureus

Streptococcus viridans

Streptococcus intermedius

Candida albicans

Explanation :
Streptococci and staphylococci are the cause of greater than 80% of infective endocarditis (IE) cases in which a responsible organism is identified.
Streptococcal species were historically the most common group of pathogens, but S. aureus as the most frequently isolated microbial agent worldwide.
Viridans group streptococci, or alpha-hemolytic streptococci, are a frequent cause of community-acquired native valve endocarditis (NVE).

MCQ – 5

In a hospital cardiac care unit, there are three patients with different cardiac conditions: a 52 year  old man with dilated cardiomyopathy, an 18 year old girl with mitral valve prolapse, and a 30 year old man with infective endocarditis of the mitral valve. Which of the following features do all these patients most likely share?

Decreased compliance

Depressed myocardial contractility

Infectious etiology

Risk of systemic thromboembolism

Explanation :
Systemic thromboembolism may develop in each of these patients. Vegetations associated with infective endocarditis may undergo fragmentation and result in systemic thromboembolism. Stasis develops in dilated ventricles, which predisposes to formation of thrombi attached to the ventricular walls (mural thrombi). Mural thrombi may also form within the left atrium in the presence of mitral valve prolapse. Thromboemboli may originate from mural thrombi.
Decreased compliance is a pathophysiologic alteration present in a variety of cardiac disorders in which there is impediment to expansion or relaxation of ventricular walls, such as restrictive cardiomyopathy, hypertrophic cardiomyopathy, and constrictive pericarditis. This feature is not present in any of the conditions described in the question.
Depressed myocardial contractility results from conditions that impair myocardial inotropism, such as dilated cardiomyopathy and ischemic heart disease. Depressed inotropism is not present in infective endocarditis or mitral valve prolapse.
Of the three conditions in the question stem, only infective endocarditis is definitely related to an infectious etiology, usually bacteria. Recall that mitral valve prolapse is due to myxomatous degeneration of the mitral valve, sometimes associated with Marfan syndrome. The etiology of dilated cardiomyopathy is heterogeneous, and most cases are idiopathic. Of the remaining cases, viral infections, toxic insults (especially alcohol), metabolic disorders (hemochromatosis), pregnancy, and genetic influences are the underlying causes.

MCQ – 6

Which of the heart valve is most likely to be involved by infective endocarditis following a septic abortion?

Aortic valve

Mitral valve

Tricuspid valve

Pulmonary valve

Explanation :
After septic abortion the bacteria spreads via the venous blood and enters the right side of the heart. So in such a case infective endocarditis of the tricuspid valve is more common.
Ref: Echocardiography By Petros Nihoyannopoulos, Page 217 ; Hurst’s The Heart, 13th Edition By Valentin Fuste, Chapter 86


MCQ – 7

Which of the following is least likely to cause infective endocarditis?

Staphylococcus aureus

Streptococcus facalis

Salmonella typhi

Pseudomonas aeruginosa

Explanation :

Among the options provided salmonella typhi is the organism least likely to cause infective endocarditis. Endocarditis is a very rare complication of salmonella typhi infection.
Ref: Harrisons Principles of Internal Medicine, 16th Edition, Page 732.

MCQ – 8

Which among the following is the least common cause of infective endocarditis?





Explanation :

Among the following, ASD is the least common cause of infective endocarditis. Here the low turbulence is responsible for decreased incidence of IE.

MCQ – 9

An IV drug user is diagnosed to have infective endocarditis involving the tricuspid valve. Which of the following is the most likely causative agent?

Staphylococcus aureus

Streptococcus gallolyticus

Pseudomonas aeruginosa

Streptococcus pyogenes

Explanation :
Prosthetic valve endocarditis is most commonly caused by Staphylococcus aureus. Many of these strains are resistant to methicillin. It usually involves the tricuspid valve. 
Prosthetic valve endocarditis usually occur within 2 months of valve surgery. It is usually due to an intraoperative contamination of prosthesis or due to a bacteremic postoperative complication. This type is usually caused by  S. aureus, Coagulase-negative staphylococci, facultative gram-negative bacilli, diphtheroids, and fungi. 

MCQ – 10

Blood culture is positive in which infection of staph. aureus-



Infective endocarditis


Explanation :

Ans. is ‘c’ i.e., Infective endocarditis

.  Blood culture is positive when bacteria present in blood, i.e. when there is bacteremia.

.  Infective endocarditis is a complication of staphylococcal aureus bacteremia (SAB). Thus blood culture may be positive.

.  Staphylococcal scalded skin syndrome (SSSS) and impetigo do not have bacteremia.

.   In toxic shock syndrome (TSS) due to staphylococcus aureus, bacteremia is uncommon (in contrast, bacteremia is common in streptococcal TSS).

MCQ – 11

A patient of RHD developed infective endocarditis after dental extraction. Most likely organism causing this is –

Streptococcus viridans

Streptococcus pneumoniae

Streptococcus pyogenes

Staphylococcus aureus

Explanation :

Ans. is ‘a’ i.e., Streptococcus viridans

Viridans streptococci are normally resident in the mouth and upper respiratory tract. They cause transient bacteremia following tooth extraction or other dental procedures; and get implanted on damaged or prosthetic valves or in a congenitally diseased heart, and grow to form vegetations.

MCQ – 12

The group of organism HACEK , causing infective endocarditis include following except –

Small VSD

Severe aortic regurgitation

Severe mitral regurgitation

Large ASD

Explanation :

Ans. is ‘d’ i.e., Large ASD

Pathogenesis of infective endocarditis (IE)

        Infective endocarditis may develop on previously normal valve, but a variety of cardiac and vascular abnormalities predispose to infective endocarditis.

o Two most common cardiac abnormalities that predispose to infective endocarditis are –

1.Rheumatic carditis

o Rheumatic carditis causes damage to heart valve.

o Damaged part of heart may be covered with platelets and fibrin, upon which bacteria can take hold. 2. Congenital heart diseases (CHDs)

o IE occurs in CHDs where blood flow occurs due to high pressure gradient, e.g. VSD or AS. o The high pressure of jet of blood hits the endocardium and damages it.

o Infection generally starts at this lesion.

High Risk                                         Moderate Risk                                                 Low Risk

Prosthetic heart valve                      MVP + M. R.                     Mitral valve prolapse without mitral Regurgitation.

MCQ – 15

Non-sterile vegetations are seen in –

Rheumatic fever

Infective endocarditis

Non bacterial thrombotic endocarditis

Libman sack’s endocarditis

Explanation :

Ans. is ‘b’ i.e., Infective endocarditis

o As the name suggests, non-sterile means presense of organism in the vegetation that is the characteristic feature of infective endocarditis.

o Vegetation of infective endocarditis has following characteristics

         Large, bulky, friable and irregular


         Present on upper surface of the cusps.

o Vegetation is a mass of platelets, fibrin, microcolonies of microorganisms (non-sterile) and scant inflammatory cells.

o Aortic and mitral valves are the most common sites of infection.

o In intravenous drug users, valves of right side are involved.

o Vegetations sometimes erode into the underlying myocardium to produce an abscess cavity —> Ring abscess. Why heart valve is the most common site of infective endocarditis ? Lets see

o As the valves of heart do not actually receive any supply of their own, defensive immune mechanism (such as WBCs) cannot approach the valves.

o So, if an organisms (such as bacteria) establishes a hold on the valve forming a vegetation, the body cannot get rid of them.

        Tricuspid valve is most commonly involved.

        Pulmonary valve is involved in fewer cases only.

        Most common organism causing endocarditis in I.V. drug abusers is =>staphylococcus aureus.

        Other common organisms are —> Candida, Enterococcus fecalis, Pseudomonas, Serratia marcescens

MCQ – 17

Which of the following is not a complication of infective endocarditis –

Myocardial ring abscess

Suppurative pericarditis

Myocardial infarction

Focal and diffuse glomerulonephritis

Explanation :

Ans. is none or ‘b’ i.e., Suppurative Pericarditis

Complications of Endocarditis

o Valvular insufficiency or stenosis with cardiac failure

  • Myocardial ring abscess with possible perforation of aorta, interventricular septum or free wall.
  • Suppurative pericarditis with endocarditis on artificial valves, partial dehiscense with paravalvular leak. o Embolic complications
  • With left sided lesions

(a)      Brain (cerebral infarct or abscess, meningitis)

(b)     Heart (Myocardial infarction)

(c)      Spleen (abscesses)

(d)     Kidney (abscesses), other sites.

o With Right sided lesions

(a) Lung (infarcts, abscess, pneumonia)

o Renal complications

                Embolic phenomenon

                Focal and diffuse glomerulonephritis due to trapping of antigen – antibody complexes which may lead to hematuria, albuminuria or renal failure.

                Multiple abscesses : especially with acute staphylococcal endocarditis.

  • So according to Robbins all of the given options can be seen. Even Braunwald’s Heart disease mentions all the four options as complications of infective endocarditis.

o If we have to go for one we will prefer suppurative pericarditis as the answer because in infective endocarditis mostly autouimmune pericarditis occurs.

MCQ – 25

Not a feature of infective endocarditis is :

Myocardial abscess

Vegetations along cusps

Thrombus in left atria

Perforation of cusp

MCQ – 31

Infective endocarditis after tooth extraction is probably due to ‑

Streptococcus viridans

Streptococcus pneumoniae

Streptococcus pyogenes

Staphylococcus aureus

Explanation :

Ans. is ‘a’ i.e., Streptococcus viridans

  • Viridans streptococci are normally resident in the mouth and upper respiratory tract. They cause transient bacteremia following tooth extraction or other dental procedures; and get implanted on damaged or prosthetic valves or in a congenitally diseased heart, and grow to form vegetations.

  • They are ordinarily non-pathogenic but can on occasion cause disease. In persons with preexisting cardiac lesions, they may cause bacterial endocarditis, Str. sanguis being most often responsible.

  • Str. Mutans are important in the causation of dental caries.

  • The transient viridans streptococcal bacteremia induced by eating, tooth-brushing, flossing and another source of minor trauma, together with adherence to biological surfaces, is thought to account for the predilection of these organisms to cause endocarditis.

  • Viridans streptococci are also isolated, often as a part of mixed flora, from sites of sinusitis, brain abscess and liver abscess.

  • Viridans streptococcal bacteremia occurs relatively frequently in neutropenic patients, particularly after bone marrow transplantation or high dose chemotherapy for cancer.

Treatment of viridans streptococcal infections include:-

  1. Bacteremia in neutropenic patients → Vancomycin.

  2. Other infection → Penicillin.
