Summary
Transseptal puncture (TSP) using radiofrequency systems can cause rare descending aorta injury, especially with interatrial septum aneurysms. This case highlights the need for caution during these procedures.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Medical Device Technology
Background:
- Aortic root injury is a known complication of transseptal puncture (TSP).
- Injury to the descending aorta during TSP has not been previously reported.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

01:22Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.
