Hypothesis
Can cardiac resynchronization therapy (CRT) be successfully implanted in patients with a coronary sinus reducer (CSR)?
Conclusion
CRT implantation is feasible in patients with CSR by utilizing proximal tributaries of the coronary sinus for lead placement.
Supporting Evidence
- CRT has proven effective in improving symptoms and prognosis in heart failure with reduced ejection fraction.
- The coronary sinus reducer can complicate lead placement but can be navigated with proper techniques.
- Three months post-CRT, the patient showed significant clinical improvement.
Takeaway
Doctors can help heart patients with a special device called a coronary sinus reducer by using nearby veins to place a heart lead, even if it seems tricky.
Methodology
The case involved a 73-year-old man where venography was used to identify suitable proximal tributaries for lead placement during CRT-D implantation.
Limitations
The experience with CSR is limited, and there are no long-term safety data on CRT implantation in patients with CSR.
Participant Demographics
A 73-year-old man with a history of chronic coronary syndrome and heart failure.
