Welcome to your Heart Failure, Cardiomyopathies, Pulmonary Edema & Heart Failure
1.
A patient with suspected heart failure has an elevated BNP concentration. Which physiological change most directly stimulates release of this peptide?

5.
Echocardiography in a child with pulmonary stenosis shows thickened valve cusps that project upward as a dome during systole. Which anatomical level is involved?
6.
A breathless patient has pedal edema, raised jugular venous pressure and basal crepitations. Which interpretation best integrates these findings?
7.
A very large ventricular septal defect produces a softer murmur than expected. Which hemodynamic condition best explains this finding?
8.

9.
A child with a large atrial septal defect remains acyanotic for many years. Which factor best explains the delayed appearance of pulmonary vascular complications compared with a large ventricular septal defect?
10.
At autopsy, a patient with long-standing heart failure has hepatomegaly and chronic passive congestion of the liver. Which underlying cardiac abnormality most likely produced this finding?
11.
A 68-year-old man with ischemic heart disease has reduced cardiac output. Sympathetic and renin–angiotensin–aldosterone system activation initially maintains his blood pressure but later worsens heart failure. Which resulting change contributes most directly to this deterioration?
12.
An adult with a previously undiagnosed atrial septal defect develops an embolic stroke despite having no thrombus in the left side of the heart. Which mechanism best explains the event?
13.
A patient with HFrEF and atrial fibrillation is prescribed digoxin. Which combination of effects explains its usefulness in this setting?
14.
A patient taking digoxin and furosemide develops anorexia, visual disturbance and ventricular ectopic beats. Which factor most likely increased the risk of toxicity?
15.
A patient with heart failure has prominent ventricular wall thickening and preserved ejection fraction. Which functional disturbance is most likely responsible for the patient’s breathlessness?
16.
A woman with HFrEF has a previous history of angioedema after antihypertensive therapy. Which drug class should be avoided when selecting treatment that reduces renin–angiotensin system activity?
17.
A child with pulmonary stenosis has enlargement of the pulmonary artery beyond the narrowed valve. Which pathological process best explains this change?
18.
A patient with HFrEF remains symptomatic despite appropriate therapy. Spironolactone is added. Which laboratory abnormality requires the closest monitoring?
19.
A 4-year-old child with Tetralogy of Fallot develops sudden deep cyanosis and rapid breathing after prolonged crying. Which immediate hemodynamic change most likely initiated this episode?
20.
A newborn with a conotruncal developmental abnormality later develops a large ventricular septal defect, overriding aorta and right ventricular outflow obstruction. Which additional cardiac change is expected to develop secondary to the obstruction?
21.
Two children have severe right ventricular outflow obstruction. One has isolated pulmonary stenosis and remains acyanotic, while the other has Tetralogy of Fallot and is deeply cyanosed. Which additional feature in the second child accounts for this difference?
22.
A patient with chronic stable HFrEF is started on a beta-blocker. Which effect provides the main long-term therapeutic benefit?
23.
Chest radiography of a cyanosed child shows an upturned cardiac apex and reduced prominence of the pulmonary artery. Which structural change most directly produces the altered cardiac contour?
24.
A ventricular septal defect is identified in the thin fibrous portion of the interventricular septum. Which type has been demonstrated?
25.
A child with an outlet ventricular septal defect develops a new diastolic murmur. Which associated complication is most likely?
26.
A patient receiving digoxin develops bradyarrhythmia after amiodarone is added. Which explanation best accounts for this interaction?
27.
A child with severe Tetralogy of Fallot has marked cyanosis but a relatively short systolic murmur. Which explanation best accounts for this finding?
28.
A patient with acute pulmonary edema has a blood pressure of 180/110 mmHg despite initial oxygen and diuretic therapy. Which additional intervention is most appropriate?
29.
A systolic murmur is heard in a child with Tetralogy of Fallot. Turbulent flow through which structure is primarily responsible for this murmur?
30.
A child with an unrepaired cyanotic congenital heart defect develops fever, headache and focal neurological weakness. Which complication should be strongly suspected?
31.
A man receiving spironolactone for heart failure develops breast tenderness and enlargement. Which alternative drug has a similar therapeutic target with a lower risk of this adverse effect?
32.
A patient in cardiogenic shock is started on milrinone. Which pharmacological effect is intended?
33.
A woman planning pregnancy asks how the risk of congenital cardiac malformations may be reduced. Which measure is most appropriate before conception?
34.
A patient has exertional dyspnea, raised jugular venous pressure and peripheral edema. Echocardiography shows normal-sized ventricles, marked biatrial enlargement and impaired ventricular filling. Which underlying process is most likely?
35.
A patient with heart failure is given a diuretic that inhibits sodium–chloride cotransport in the distal convoluted tubule. Which adverse-effect profile is most consistent with this treatment?
36.
During a SWOT analysis of managing acute pulmonary edema, a student identifies access to supervised simulation and bedside echocardiography training. How should these factors be classified?
37.
A patient presents with acute severe dyspnea, diffuse crepitations and oxygen desaturation. Blood pressure is 170/100 mmHg. After positioning and oxygen support, which treatment is most appropriate to reduce pulmonary congestion rapidly?
38.
Pulmonary tissue from a child with a long-standing large ventricular septal defect shows medial thickening and intimal proliferation in small pulmonary arteries. Which clinical outcome is most closely related to these changes?
39.
A patient with chronic heart failure has dyspnea, orthopnea and bilateral basal crepitations. Which hemodynamic abnormality most directly explains these respiratory findings?
40.
An echocardiogram demonstrates an atrial septal opening located near the fossa ovalis. Which anatomical type is most likely?
