The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing to provide real‐time visual resistance feedback that partially compensates for the lack of direct tactile sensation, along with streamlined device exchange and an intuitive joystick–roller interface. Aims This study aimed to evaluate the feasibility, safety, and procedural performance of the ETcath200 system in patients with complex coronary lesions. Methods In this prospective, single‐center, single‐arm trial, 20 patients with AHA/ACC type B2 or C complex coronary lesions underwent PCI using the ETcath200 system. Technical success was defined as full robotic completion without any unplanned manual input (including partial manual assistance or manual conversion); clinical success as residual stenosis < 30% with TIMI 3 flow and no in‐hospital major adverse cardiac events (MACE). Patients were followed for 30 days. Results All 20 patients (mean age 63.2 ± 12.0 years; 80% male) had unstable angina and complex coronary anatomy (79.2% type C lesions; 50% bifurcation, 65% diffuse). Most procedures were performed via radial access (80%), and the majority utilized drug‐eluting stents (65%). Technical success was achieved in 16 cases (80%), while four cases (20%) required manual conversion due to severe tortuosity or calcification ( n = 3) or guidewire‐induced dissection ( n = 1; managed successfully). All patients achieved clinical success; no device failures, MACE, or serious adverse events occurred at 30 days. Mean procedure duration was 61.0 ± 23.3 min; radiation dose was 0.07 ± 0.04 mSv. Conclusions The ETcath200 robotic PCI system demonstrated feasibility, safety, and reliable performance in complex coronary lesions, achieving high clinical success and excellent short‐term outcomes. Manual conversion was required only in anatomically challenging cases. These data support further multicenter evaluation of ETcath200 in complex coronary interventions. 10.1002/ccd.70488 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
