Two is company, three is a crowd.

Area of Science:

• Cardiology
• Vascular Surgery
• Medical Device Technology

Background:

• Superior Vena Cava (SVC) syndrome is a clinical condition often associated with malignant tumors.
• The incidence of SVC syndrome has shifted, with intravascular devices now accounting for a significant proportion of cases.
• Pacemakers and implantable cardioverter-defibrillators (ICDs) are increasingly implicated in SVC syndrome.

Observation:

• A young patient with a history of permanent pacemaker implantation presented with SVC syndrome.
• The patient underwent central venous catheter (CVC) placement prior to surgery for hypertrophic cardiomyopathy.
• This case underscores the potential complications associated with indwelling vascular devices.

Findings:

• The patient's presentation of SVC syndrome was linked to the presence of both a pacemaker and a recently placed CVC.
• This case illustrates a non-malignant etiology of SVC syndrome in a patient with multiple intravascular devices.
• The temporal relationship between device placement and symptom onset suggests a causal link.

Implications:

• Clinicians should maintain a high index of suspicion for SVC syndrome in patients with pacemakers or CVCs, even in the absence of malignancy.
• Early recognition and management of device-related SVC syndrome are crucial for patient outcomes.
• Further research into preventative strategies and optimal management of device-associated SVC syndrome is warranted.
