Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Studies II: Thoracocentesis

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Background:

A 72-year-old male with a history of complete heart block, renal cell carcinoma, and thyroid cancer presented with an incidentally discovered 4-cm right atrial mass.

Observation:

Cardiovascular CT angiography showed an infiltrative mass along the atrioventricular grooves, interventricular groove, interatrial septum, right ventricle free wall, and right atrium.
Transesophageal echocardiography revealed a heterogeneous mass extending into the superior vena cava and possibly involving the aortic root.

Findings:

Cardiac biopsy of the right atrial mass was successfully performed using an endobronchial alligator forceps under intracardiac echocardiographic guidance.
The biopsy procedure was completed without complications, despite initial difficulties with traditional biopsy devices.

Implications:

This case highlights a novel and effective technique for obtaining tissue diagnosis of challenging cardiac masses.
Successful biopsy using an endobronchial alligator forceps under intracardiac echocardiographic guidance offers a viable option for complex cardiac mass biopsies.
