Q

A syndrome resulting from insufficient left ventricular output. What is this condition?

A

Left ventricular failure (LVF)

18
Q

A syndrome resulting from insufficient right ventricular output. What is this condition?

A

Right ventricular failure (RVF)

19
Q

Chest pain, syncope and breathelessness. Most common valve disease. What is this condtion?

A

Aortic stenosis

20
Q

Breathelessness and palpitations presentation. Valve disease caused by diseases which dilate the aortic root (Eg Marfan’s syndrome, ankylosing spondylitis). What is this condition?

A

Aortic regurgitation.

21
Q

Pulmonary oedema and breathelessness presentation. Usually the result of chronic rehumatic valvular disease. Associated with atrial fibrillation. What condition is this?

A

Mitral Stenosis

22
Q

Valvular disease usually due to mitral valve prolapse or ischaemic heart disease. Often asymptomatic but eventually developes into LVF. What is this condition?

A

Mitral regurgitation

23
Q

Myocardial biopsy: Myocyte hypertrophy, myocyte disarray and interstitial fibrosis. Most likely diagnosis?

A

Hypertrophic cardiomyopathy (HCM)

///////////////////////////

*Key histology here*

24
Q

Cardiac pathology associated with Beta-myosin heavy chain mutations. What condition is this?

A

Hypertrophic cardiomyopathy

25
Q

The interventricular septum thickens so much that is causes an obstruction of outflow of blood from the heart. What condition is this?

A

Hypertrophic Obstructive Cardiomyopathy (HOCM)

26
Q

Presentation of breathlessness, fatigue and palpitations. Progressive loss of myocytes. Has genetic causes: Haemochromatosis, Fabry’s disease, McArdle’s disease. What is this condition?

A

Idiopathic dilated cardiomyopathy

/////////////////

Also associated with thrombus formation?

27
Q

Diastolic dysfunction. Quiet heart sounds, raised JVP with Kussmaul’s sign, ascites, hepatomegaly, oedema. Caused by sarcoidosis, amyloidosis, radiation induced fibrosis. What is this condition?

A

Restrictive Cardiomyopathy

//////////////////////////////////////////////

Presentations are similar to

  • (Constrictive pericarditis pres)
  • (RVF pres)
28
Q

Myocyte loss with fibrofatty replacement, normally affecting the right ventricle. What is this condition?

A

Arrhythmogenic right ventricular cardiomyopathy (ARVC)

29
Q

Pathogenic organisms infecting a structurally normal heart. Usually caused by Staphylococcus Aureus. Presents with fever and signs of valve damage. Major systemic embolisms can occur. What condition is this?

A

Left Sided Acute Endocarditis

30
Q

Pathogenic organisms infecting a structurally normal heart. Usually caused by Staphylococcus Aureus. Presents with fever and signs of valve damage. Also, chills and pulmonary symptoms. What condition is this?

A

Right sided acute endocarditis

31
Q

Weaker organisms, infecting a structurally abnormal heart. Most commonly due to Streptococcus Viridans or Enterococci. Presents with low grade fever and constitutional symptoms.

A

Subacute endocarditis

//////////////////////////////////

Diagnosis often goes missed

32
Q

Histopathology: vegetations composed of a mixture of fibrin inflammatory cells and bacterial colonies which are usually gram +ve cocci. Most likely diagnosis?

A

Infective endocarditis

33
Q

Inflammation of the myocardium, unrelated to ischaemia (Mostly due to infection). Most common organism involved: Coxsackie virus. Myocyte injury, causing necrosis and inflammation. Presents: Mild, flu-like illness. Severe, myocardial infarction like presentation. Severe cases can cause. What is this condition?

A

Myocarditis

34
Q
A
35
Q

Many causes. Mainly caused by infection (Coxsackie virus) full-thickness MI, severe renal failure (uraemic pericarditis). Presents as chest pain alleviated by sitting forward. Pericardium is infiltrated by inflammatory cells, often with fibrin deposition. Malignant cells may be seen in malignant infiltration

A

pericarditis

//////////////////

Inflammation of the pericardium.
