Insights
A rare Gerbode-type ventricular septal defect occurred after heart valve surgery. Percutaneous closure successfully treated the defect, resolving the patient's symptoms of hematuria and hemolysis.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Iatrogenic Gerbode-type ventricular septal defects (VSDs) are uncommon complications following cardiac valve surgery.
- Prompt diagnosis and management are crucial for patient outcomes.
Observation:
- A 23-year-old male presented with hematuria and hemolysis three months post mitral and tricuspid valve replacement.
- Diagnostic evaluations, including echocardiography and catheterization, identified a Gerbode-type VSD.
Findings:
- The patient underwent successful interventional occlusion of the Gerbode-type VSD.
- Hematuria resolved immediately post-procedure, indicating effective defect closure.
Implications:
- Percutaneous VSD closure is a viable and often preferred alternative to surgical re-operation for iatrogenic defects.
- Timely and appropriate intervention can significantly improve patient recovery and prevent further complications.
Abstract:
A 23-year-old man was referred to our center with hematuria and hemolysis. The patient had undergone mitral and tricuspid valve replacement 3 months previously. Echocardiography and catheterization revealed a Gerbode-type ventricular septal defect. A decision was made to occlude the defect interventionally. The patient's hematuria ceased immediately after the occlusion of the defect. <Learning objective: Iatrogenic ventricular septal defects (especially Gerbode-type) are relatively rare complications after valvular surgery. Correction of such defects can be done both surgically and interventionally, but since the risk of another operation for correction is high, percutaneous ventricular septal defect closure is usually the preferred treatment option. Using an appropriate approach will increase the success rate.>.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
