Provisional versus routine coronary stenting. A review.

Coronary stenting is widely adopted for revascularization due to its predictable outcomes in specific lesion types. Prior research has shown balloon angioplasty alone has suboptimal results in many cases. This gap motivated evaluating alternative strategies. Established knowledge includes the safety and efficacy of stents in certain coronary lesions. No prior work had resolved whether all stentable lesions should be routinely stented. Theoretical advantages of provisional stenting include reduced device use and cost. However, the evidence base is mixed between retrospective and prospective studies. This uncertainty drives the need for a synthesis of current findings.

This review aims to compare provisional and routine coronary stenting strategies. The specific problem is whether all stentable lesions should be stented. The motivation comes from conflicting evidence between retrospective and prospective studies. Retrospective data suggested similar outcomes with provisional stenting. Prospective studies, however, suggest routine stenting may be superior. The goal is to synthesize findings to guide clinical practice. The review focuses on angiography-guided provisional stenting. It also considers alternative imaging techniques like intravascular ultrasound.

The review synthesizes retrospective and prospective studies comparing stenting strategies. Retrospective data included vessel recoil after balloon angioplasty. Prospective randomized trials used angiography to guide provisional stenting. Comparative analysis focused on target revascularization rates. The review also considered economic implications of each strategy. Alternative imaging techniques were evaluated for guiding stenting. Outcomes were measured using angiographic success and revascularization rates. The authors analyzed whether coronary flow reserve or ultrasound could improve provisional stenting.

Retrospective studies suggested similar revascularization rates with provisional stenting. Prospective randomized trials found better outcomes with routine stenting. Angiography-guided provisional stenting did not match routine stenting results. Over half of the balloon angioplasty group required stenting. Economic analysis showed no cost advantage for provisional stenting. Coronary flow reserve or ultrasound may improve provisional stenting outcomes. Routine stenting remains more justifiable with current angiography guidance. Further stent technology advancements may enhance routine stenting benefits.

The authors suggest routine stenting is more justifiable with current angiography guidance. They propose that provisional stenting needs alternative imaging to match routine results. No prior work had resolved the economic implications of each strategy. The review highlights that over half of balloon angioplasty cases still require stents. Routine stenting may become even more attractive with drug-coated stents. The findings are based on prospective randomized trials and economic analyses. The authors do not claim routine stenting is essential for all cases. They suggest further research on imaging-guided provisional stenting.
