Part OneA 67-year-old woman with congestive cardiac failure remains breathless on moderate exertion despite treatment with 40 mg frusemide and 20 mg enalapril daily On examination she has a pulse rate of 80minute blood pressure of 12570 mmHg and a jugular venous pressure (JVP) of +1 cm She has a soft systolic murmur with no added sounds her chest is clear and she has no oedema An ECG shows sinus rhythm A chest X-ray shows cardiomegaly with a cardiothoracic ratio of 15528 but no pulmonary congestion Echocardiography demonstrates systolic dysfunction with fractional shortening of 18 and mild mitral regurgitation Her serum creatinine level is normal
Which of the following is the most appropriate next step in treatment A Increase the frusemide dose B Add digoxin C Add an aldosterone antagonist D Add an angiotensin II receptor antagonist E Add a beta blocker

The regurgitant fraction in this patient is A 25 B 33 C 50 D 67 E 75
Part OneA 45-year-old asymptomatic man returns for follow-up He was diagnosed 10 years ago with aortic regurgitation due to a congenital bicuspid aortic valve He has never had endocarditis Which one of the following echocardiographic profiles most strongly indicates the need for aortic valve replacement

Part OneA 35-year-old woman has increasing breathlessness on exertion Her cardiac silhouette is slightly enlarged on a chest X-ray and an ECG demonstrates sinus rhythm The continuous wave Doppler flow signal through the mitral inflow tract (shown above) is most consistent with which one of the following A Severe pulmonary hypertension (cor pulmonale) B Aortic stenosis C Mitral regurgitation D Mitral stenosis E Aortic regurgitation
Part OneA 28-year-old woman who emigrated from Cambodia 10 years ago presents to the emergency department with a three-week history of increasing shortness of breath orthopnoea nocturnal dyspnoea and ankle oedema She is 25 weeks pregnant and has no significant past medical history The presence of pulmonary oedema is confirmed clinically and radiologically She responds well to intravenous frusemide but remains tachypnoeic with a heart rate of 120minute in sinus rhythm Her blood pressure is 12585 mmHg Echocardiography demonstrates mitral stenosis with an estimated valve area of 13 cm2 and a left atrial diameter of 50 mm [lt40 mm] There are no other abnormalities What is the most appropriate next step in management A Balloon valvotomy B Surgical valvotomy C Digoxin therapy D Beta-blocker therapy E Angiotensin converting enzyme (ACE) inhibitor therapy
Part OneA 55-year-old man presents with acute pulmonary oedema Five years earlier he has undergone a mitral valve replacement with a bileaflet tilting disk valve (St Jude) for mixed mitral valve disease He has been well with normal exercise tolerance prior to the day of admission Examination on admission reveals tachypnoea sinus tachycardia of 110minute blood pressure of 10560 mmHg elevated jugular venous pressure (+ 5 cm) and bilateral crepitations throughout the lung fields His prothrombin timeminusinternational normalised ratio (PT-INR) is 19 [desired therapeutic range 20-35] Serum urea creatinine and electrolytes are normal The cardiothoracic ratio on chest X-ray is normal but the presence of pulmonary oedema is confirmed Echocardiography reveals that one of the prosthetic valve leaflets is not moving and there is an increased flow rate in diastole across the valve orifice (2 metressecond) What is the most appropriate course of action A Administration of intravenous streptokinase B Administration of intravenous heparin C Administration of intravenous antibiotics D Addition of an antiplatelet agent E Immediate mitral valve replacement

Part OneThe severity of pulmonary hypertension can be determined using continuous wave Doppler measurements of the velocity of tricuspid regurgitation This method uses the Bernoulli equation which states that 1048661P = 4v2 (where 1048661P = instantaneous pressure gradient and v = velocity across the valve) There is tricuspid regurgitation with a peak velocity of 4 metressecond and a mean velocity of 35 metressecond Assuming right atrial pressure is 5 mmHg the best estimate of the peak right ventricular systolic pressure (plusmn 2 mmHg) is

Part OneA 28-year-old woman who emigrated from Cambodia 10 years ago presents to the emergency department with a three-week history of increasing shortness of breath orthopnoea nocturnal dyspnoea and ankle oedema She is 25 weeks pregnant and has no significant past medical history The presence of pulmonary oedema is confirmed clinically and radiologically She responds well to intravenous frusemide but remains tachypnoeic with a heart rate of 120minute in sinus rhythm Her blood pressure is 12585 mmHg Echocardiography demonstrates mitral stenosis with an estimated valve area of 13 cm2 and a left atrial diameter of 50 mm [lt40 mm] There are no other abnormalities What is the most appropriate next step in management A Balloon valvotomy B Surgical valvotomy C Digoxin therapy D Beta-blocker therapy E Angiotensin converting enzyme (ACE) inhibitor therapy
Part OneA 55-year-old man presents with acute pulmonary oedema Five years earlier he has undergone a mitral valve replacement with a bileaflet tilting disk valve (St Jude) for mixed mitral valve disease He has been well with normal exercise tolerance prior to the day of admission Examination on admission reveals tachypnoea sinus tachycardia of 110minute blood pressure of 10560 mmHg elevated jugular venous pressure (+ 5 cm) and bilateral crepitations throughout the lung fields His prothrombin timeminusinternational normalised ratio (PT-INR) is 19 [desired therapeutic range 20-35] Serum urea creatinine and electrolytes are normal The cardiothoracic ratio on chest X-ray is normal but the presence of pulmonary oedema is confirmed Echocardiography reveals that one of the prosthetic valve leaflets is not moving and there is an increased flow rate in diastole across the valve orifice (2 metressecond) What is the most appropriate course of action A Administration of intravenous streptokinase B Administration of intravenous heparin C Administration of intravenous antibiotics D Addition of an antiplatelet agent E Immediate mitral valve replacement

Part OneA 55-year-old man presents with acute pulmonary oedema Five years earlier he has undergone a mitral valve replacement with a bileaflet tilting disk valve (St Jude) for mixed mitral valve disease He has been well with normal exercise tolerance prior to the day of admission Examination on admission reveals tachypnoea sinus tachycardia of 110minute blood pressure of 10560 mmHg elevated jugular venous pressure (+ 5 cm) and bilateral crepitations throughout the lung fields His prothrombin timeminusinternational normalised ratio (PT-INR) is 19 [desired therapeutic range 20-35] Serum urea creatinine and electrolytes are normal The cardiothoracic ratio on chest X-ray is normal but the presence of pulmonary oedema is confirmed Echocardiography reveals that one of the prosthetic valve leaflets is not moving and there is an increased flow rate in diastole across the valve orifice (2 metressecond) What is the most appropriate course of action A Administration of intravenous streptokinase B Administration of intravenous heparin C Administration of intravenous antibiotics D Addition of an antiplatelet agent E Immediate mitral valve replacement

Cardiac Tamponade
Cardiac Tamponade
Part OneA 65-year-old woman presents with a one-week history of progressive dyspnoea On admission there are signs of shock a systolic murmur and an elevated jugular venous pressure The ECG shows sinus tachycardia but no other abnormality An antero-posterior chest X-ray shows cardiomegaly The serum troponin I level is 05 mgL [lt01] A computed tomography (CT) scan is shown below
What is the most likely diagnosis A Pulmonary embolism B Right ventricular infarction C Pericardial tamponade D Myocarditis E Acute mitral regurgitation
Endocarditis
Positive echocardiogram for IE Discrete echogenic oscillating intracardiac mass located at a site of endocardial injury (eg on a valve or supporting structure in pathway of regurgitant jet or site of implanted material) or Periannular abscess or
New dehiscence of a prosthetic valve
