To evaluate long-term clinical and angiographic outcomes following Palmaz-Schatz coronary stent implantation and evaluate repeat interventions for in-stent restenosis.
Conducted a single-center study of 411 patients (427 lesions) receiving Palmaz-Schatz stents between June 1990 and September 1993.
Performed follow-up coronary angiography in 307 lesions at 3–6 months and 189 lesions at 1 year, alongside clinical monitoring over a mean of 22 ± 9 months.
Stent placement achieved a 97.2% procedural success rate, 94.6% clinical success rate, 2.2% thrombosis rate, and a 74.3% cardiac event-free survival rate over 22 months.
Angiographic restenosis occurred in 16.3% of lesions at 3–6 months, whereas new restenosis appeared in only 2.3% at 1 year, with stable minimal lumen diameter (2.32 ± 0.51 mm vs 2.30 ± 0.54 mm).
Repeat intervention in 35 restenotic lesions yielded a 32.1% recurrence rate (9 of 28 re-evaluated), which was significantly higher for diffuse lesions than focal lesions (75.0% vs 7.7%).

Structured PICO

Population

411 patients with 427 coronary lesions

Intervention

Palmaz-Schatz coronary stent placement

Outcome

Long-term clinical and angiographic follow-up results including procedure success, clinical success, angiographic restenosis, and cardiac event-free survival

Palmaz-Schatz coronary stenting is associated with high initial success, low late restenosis, and stable luminal dimensions beyond 6 months.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Associated with high success and low restenosis; leaves open randomized comparisons to balloon angioplasty and modern stents.
