Background:

• Coronary artery bypass grafting (CABG) is standard for unprotected left main coronary artery disease.
• Severe comorbidities can make CABG unsuitable, necessitating alternative treatments like percutaneous coronary intervention (PCI).
• High-risk PCI often requires hemodynamic support for patient safety.

Purpose of the Study:

• To evaluate the use of the TandemHeart percutaneous ventricular assist device (pVAD) in high-risk PCI procedures.
• To assess the safety and efficacy of pVAD for hemodynamic support during complex PCI.
• To determine the role of pVAD in managing patients ineligible for CABG.

Main Methods:

• The study involved 5 consecutive patients with severe comorbidities who were not candidates for CABG.
• The TandemHeart pVAD was utilized for hemodynamic support during high-risk PCI in these patients.
• Device insertion and initiation of circulatory support were performed, followed by percutaneous revascularization.

Main Results:

• The pVAD was successfully inserted and initiated support in all 5 cases without immediate complications.
• Percutaneous revascularization was completed successfully with pVAD support, providing approximately 3 L/min of flow.
• Four patients recovered uneventfully after short-term pVAD support; one patient died 10 days post-withdrawal due to heart failure and mitral regurgitation.

Conclusions:

• The pVAD can provide adequate hemodynamic support during high-risk PCI, potentially reducing morbidity and mortality.
• This device expands therapeutic options for patients with severe comorbidities who are not surgical candidates.
• Further research is recommended to fully explore the potential of the pVAD in complex PCI scenarios.
