❤️🩸 Infective Endocarditis – Renal Infarction

✅ Answer: (B) Renal Infarction

📖 What is Infective Endocarditis?

Infective = Caused by microorganisms (usually bacteria)
Endo = Inner
Carditis = Inflammation of the heart

👉 Infective Endocarditis (IE) is an infection of the inner lining of the heart (endocardium), usually involving the heart valves.

In IE, infected clumps called vegetations form on the valves. Small pieces of these vegetations can break off and travel through the bloodstream as septic emboli.

🩺 Why is Option (B) Correct?

A septic embolus can block the renal artery, cutting off blood supply to part of the kidney.

This causes a renal infarction, which typically presents with:

• ✔ Sudden severe flank pain
• ✔ Hematuria (blood in urine)
• ✔ Possible fever and nausea
• ✔ Elevated LDH due to tissue damage

👉 The combination of infective endocarditis + sudden flank pain + hematuria is highly suggestive of renal infarction.

❌ Why Other Options Are Wrong?

(A) Acute Pyelonephritis
❌ Usually presents with fever, chills, dysuria, costovertebral angle tenderness, and urinary infection symptoms. It is not a typical embolic complication of infective endocarditis.

(C) Cystitis
❌ Causes burning during urination, urinary frequency, and urgency. Severe flank pain is uncommon.

(D) Hydronephrosis
❌ Caused by obstruction of urine flow. Although flank pain can occur, it is not a common embolic complication of infective endocarditis.

📝 Embolic Complications of Infective Endocarditis

📌 Exam Tip: In infective endocarditis, sudden symptoms affecting another organ usually indicate an embolic complication. For the kidney, the classic MCQ clue is sudden flank pain with hematuria, pointing to renal infarction.
