1. Auscultation of a murmur in the right sternal border indicates a
problem with which valve?
Answer✅: Aortic valve
• Rationale: The right upper sternal border (2nd intercostal space) is the classic
auscultatory area for the aortic valve. Sound is transmitted here along the direction of
blood flow as it exits the left ventricle into the ascending aorta.
2. Auscultation of a murmur in the left upper sternal border indicates
a problem with which valve?
1
,Answer✅: Pulmonic valve
• Rationale: The left upper sternal border (2nd intercostal space) aligns with the
pulmonic area. Murmurs heard loudest here typically involve the pulmonic valve,
reflecting blood flow from the right ventricle into the pulmonary artery.
3. Auscultation of a murmur in the left lower sternal border indicates
a problem with which valve?
Answer✅: Tricuspid valve, aortic valve
• Rationale: The left lower sternal border (4th/5th intercostal space) represents the
tricuspid area. Additionally, regurgitant murmurs from the aortic valve (aortic
regurgitation) are frequently transmitted down along the left sternal border due to the
retrograde direction of blood flow into the left ventricle.
4. Auscultation of a murmur in the apex indicates a problem with
which valve?
Answer✅: Mitral valve
• Rationale: The cardiac apex (5th intercostal space, midclavicular line) corresponds to
the left ventricular tip, where the mitral valve sounds are maximally transmitted and
heard most clearly.
5. What are the causes of aortic stenosis?
Answer✅:
• Bicuspid aortic valve (congenital condition)
• Age-related calcification (accelerated by smoking, HTN, HLD)
• Rheumatic fever / rheumatic heart disease
• Rationale: In younger patients (<65 years), a congenital bicuspid valve is the most
common cause. In older adults (>65 years), wear-and-tear leading to dystrophic
calcification dominates. Rheumatic heart disease remains a notable cause globally,
often causing fusion of the valve commissures.
6. What are the signs and symptoms (S&S) of aortic stenosis?
Answer✅:
2
, • Left ventricular hypertrophy (LVH) – Point of Maximal Impulse (PMI) is
shifted/displaced laterally
• Syncope (exertional)
• Angina (exertional chest pain)
• Dyspnea (exertional shortness of breath)
• Pulsus parvus et tardus
• Microangiopathic hemolytic anemia (MAHA)
• Rationale: The classic triad of severe aortic stenosis includes Syncope, Angina, and
Dyspnea (SAD). Concentric LVH occurs as the left ventricle pumps against a high
afterload, causing lateral displacement of the PMI.
7. What is pulsus parvus et tardus?
Answer✅: A small, weak arterial pulse that is slow to rise.
• Rationale: "Parvus" means small/weak amplitude, and "tardus" means delayed or
slow peak. This physical finding occurs because the stenosed aortic valve severely
restricts and delays the ejection of blood into the systemic circulation during systole.
8. What does MAHA stand for?
Answer✅: Microangiopathic hemolytic anemia
• Rationale: MAHA is a descriptive term for a subtype of hemolytic anemia caused by
structural or mechanical damage occurring within the microvasculature or across a
highly stenosed, calcified macrovascular structure like the aortic valve.
9. What happens in MAHA associated with aortic stenosis?
Answer✅: Red blood cells (RBCs) get sheared and broken apart as they travel across
the very tight, calcified valve, resulting in hemolytic anemia.
• Rationale: The narrowed, turbulent orifice of a stenotic aortic valve acts as a
mechanical "meat grinder." The extreme shear stress forces RBCs to fragment into
schistocytes, triggering intravascular hemolysis.
10. What type of murmur is heard with aortic stenosis?
Answer✅: A systolic ejection murmur with a crescendo/decrescendo pattern.
