A 21-year old male presents with exeional dyspnea, raised JVP and loud P2. ECG shows right axis detion. All of the following conditions are possible except’
**Core Concept**
The patient's presentation suggests a condition affecting the right heart, leading to increased pressure and strain on the right ventricle. The key symptoms include exertional dyspnea, raised JVP (jugular venous pressure), and a loud P2 (pulmonic component of the second heart sound), which are indicative of pulmonary hypertension or a right-sided heart condition.
**Why the Correct Answer is Right**
The patient's ECG showing right axis deviation is a common finding in conditions that affect the right heart, such as pulmonary hypertension, cor pulmonale, or right ventricular hypertrophy. The pathophysiology involves increased pressure in the pulmonary arteries, which leads to right ventricular hypertrophy and eventual failure. The loud P2 is a result of the increased pressure in the pulmonary artery, causing the pulmonary valve to open wider and produce a louder sound.
**Why Each Wrong Option is Incorrect**
**Option A:** **Pulmonary Embolism** - This is a possible condition that could explain the patient's symptoms, as a large PE can cause sudden onset of pulmonary hypertension and right ventricular strain.
**Option B:** **Left Ventricular Failure** - This is not a likely cause, as left ventricular failure would more likely present with signs of left-sided heart failure, such as pulmonary edema and a left axis deviation on ECG.
**Option C:** **Cor Pulmonale** - This is a possible condition, as it is characterized by right ventricular hypertrophy and failure, which could explain the patient's symptoms.
**Option D:** **Mitral Stenosis** - This is a possible condition that could cause pulmonary hypertension, as the stenotic mitral valve would lead to increased pressure in the left atrium, which would eventually cause pulmonary hypertension.
**Clinical Pearl / High-Yield Fact**
In patients presenting with exertional dyspnea and raised JVP, always consider the possibility of pulmonary hypertension or cor pulmonale, and look for signs of right ventricular hypertrophy on the ECG.
**Correct Answer:** B. Left Ventricular Failure
