The VSTENT was implanted distal to a hemodynamically relevant coronary artery stenosis. Coronary flow velocity was assessed at rest and during dobutamine stress. Intraoperative VSTENT implantation was successful in 11 of 12 patients. Early postoperative angiograms showed patent VSTENT in 8 of 11 patients, with predominantly systolic flow distal to the VSTENT. Coronary flow velocity reserve induced by dobutamine stress was 1.7\u00b10.1 (\n            <jats:italic>P<\/jats:italic>\n            =0.006). VSTENT patency at 2- to 6-month follow-up was present in 5 of 11 patients, with concomitant VSTENT stenosis in 4 of those 5. In all patients, coronary flow velocity increased 3- to 4-fold proximal to the VSTENT, which was associated with a moderate degree of arterial remodeling. Except for target vessel reintervention (n=5), no other major adverse events were observed in 11 of 12 patients. One patient died on the second postoperative day, though the cause was probably not related to the VSTENT implantation.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            VSTENT implantation seems to be safe in the mid-term follow-up and leads to a predominantly systolic coronary flow pattern in the vessel supplied by the VSTENT, with a flow reserve similar or close to that seen with conventional bypass. VSTENT patency rate, however, was unacceptably low at 3- to 6-month follow-up and needs to be improved.\n          <\/jats:p>","DOI":"10.1161\/circulationaha.104.524751","type":"journal-article","created":{"date-parts":[[2021,7,3]],"date-time":"2021-07-03T03:23:18Z","timestamp":1625282598000},"update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Hemodynamic and Vascular Effects of Ventricular Sourcing by Stent-Based Ventricle to Coronary Artery Bypass in Patients With Multivessel Disease Undergoing Coronary Artery Bypass Surgery"],"prefix":"10.1161","volume":"112","author":[{"given":"Peter","family":"Boekstegers","sequence":"first","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip","family":"Raake","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rabea","family":"Hinkel","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tilmann","family":"Pohl","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Kupatt","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Knez","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Christ","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Eifert","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerhard","family":"Steinbeck","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Reichart","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Calin","family":"Vicol","sequence":"additional","affiliation":[{"name":"From the Departments of Internal Medicine I (P.B., P.R., R.H., T.P., C.K., A.K., G.S.), Anesthesiology (F.C.), and Cardiac Surgery (S.E., B.R., C.V.), Grosshadern University Hospital, Munich, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.cir.0000027106.88111.77"},{"key":"e_1_3_1_2_2","first-page":"307","volume":"21","year":"2001","unstructured":"Suehiro K, Shimizu J, Yi GH, Zhu SM MD, Gu A, Sciacca RR, Wang J, Burkhoff D.
