Methods. Primary studies explicitly reporting US-PC or with separable data were included. Primary outcomes: technical success, clinical success (as defined by the study), and major adverse events (AEs). Single-arm meta-analysis using random-effects (logit, continuity correction); heterogeneity by I2 and prediction interval. Results. Four eligible single-arm studies for technical success (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009466). Pooled technical success 99.3% (95%CI 97.8\u201399.8; I2\u2009=\u20090%). Three studies (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009223) reported clinical success: pooled 97.6% (95%CI 83.4\u201399.7; I\n                      <jats:sup>2<\/jats:sup>\n                      \u224864% due to varying definitions).

Thirty-day mortality is available from one large study (6.2%). Conclusions. In high-risk patients, US-PC demonstrates very high technical success and low major complication rates; clinical success is high but variably defined across studies.
