Prepare for the cardiology boards with these high-yield practice scenarios and explanations.
Question 1: Valvular Pathology
A 70-year-old male presents with exertional syncope, dyspnea, and angina. On examination, a harsh cresc-decresc systolic murmur is heard at the second right intercostal space, radiating to the carotids. What is the most appropriate next step in management?
- Explanation: This clinical triad (Syncope, Angina, Dyspnea) points directly to severe Aortic Stenosis. The diagnostic gold standard and next best step is an Echocardiogram to assess valve area and transvalvular gradients.
Question 2: Arrhythmia Management
A 65-year-old female presents with palpitations and fatigue. ECG shows irregular rhythm with absent P waves. The patient is hemodynamically stable. What is the priority treatment?
- Explanation: The ECG features are pathognomonic for Atrial Fibrillation. In a hemodynamically stable patient, the primary goals are rate control (e.g., beta-blockers) and stroke prevention assessment using the CHA2DS2-VASc score.
