Is coronary vein angioplasty necessary to provide cardiac resynchronization in selected patients? A case report

Area of Science:

• Cardiology
• Medical Devices

Background:

• Cardiac resynchronization therapy (CRT) is recommended for heart failure patients with cardiac dyssynchrony.
• CRT implantation can face anatomical and technical challenges, sometimes requiring venous interventions.

Observation:

• A 58-year-old male with atrial fibrillation and heart failure was referred for CRT.
• During implantation, a diaphragmatic obstacle in the coronary sinus (CS) was navigated after multiple attempts without balloon inflation.

Findings:

• The case highlights a situation where a challenging CS anatomy was overcome without resorting to venous angioplasty.
• This suggests that venous angioplasty might not always be necessary for successful CRT lead placement.

Implications:

• Further discussion is needed on the necessity and indications for coronary sinus venous angioplasty during CRT implantation.
• Optimizing CRT procedures by carefully evaluating the need for interventions like angioplasty is crucial for patient outcomes.
