Angiography is performed at the level of the LIPV to visualize its course. Subsequently, a quadripolar ventricular lead is advanced through the sheath into the LIPV to conduct diaphragmatic pacing testing, observing the diaphragmatic pacing effectiveness and its impact on cardiac activity. Upon test completion, the catheter and lead are withdrawn, and the standard pacemaker implantation procedure is continued.",[9],[21],{"name":22,"role":23,"phone":24,"phoneExt":11,"email":25},"Tianbao Dr. Yao, MD","CONTACT","+86 13661684786","yaotianbao@renji.com",[27],{"facility":28,"status":29,"city":30,"state":31,"zip":32,"country":33,"countryCode":34,"cosmosGeoPoint":35,"geoPoint":40,"contacts":41},"Renji Hospital","RECRUITING","Shanghai","Shanghai Municipality","200127","China","CN",{"type":36,"coordinates":37},"Point",[38,39],121.45806,31.22222,{"lat":39,"lon":38},[42,43],{"name":22,"role":23,"phone":24,"phoneExt":11,"email":25},{"name":44,"role":45,"phone":11,"phoneExt":11,"email":11},"Tianbao Yao, MD","PRINCIPAL_INVESTIGATOR",{"type":45,"investigatorFullName":47,"investigatorTitle":48,"investigatorAffiliation":5,"oldNameTitle":11,"oldOrganization":11},"Tianbao Yao","Associate Chief Physician","100623139","feasibility-study-of-diaphragm-synchronized-pacing-dsp-via-the-left-inferior-phrenic-vein-lipv-approach-100623139",false,"NCT07392749","Feasibility Study of Diaphragm Synchronized Pacing (DSP) Via the Left Inferior Phrenic Vein (LIPV) Approach","Inclusion Criteria:\n\n* Patients aged \\>=18 yrs;\n* Patients indicated for CRT or CRT-D , planned for LV lead implantation;\n* Patients are willing to participate in the study and provide signed informed consent\n\nExclusion Criteria:\n\n* CRT or CRT-D replacement\n* Ischemic heart disease with CABG history\n* Diaphragm dysfunction history\n* Phrenic nerve injury\n* IVC filter history\n* Abdominal surgery history\n* Splenomegaly\n* Pulmonary disease\n* Moderate or severe liver cirrhosis\n* Severe hepatic or renal dysfunction\n* Currently pregnant or planning pregnancy during the study period\n* Patients participate in another study that will confound this study","ALL","18 Years",{"count":58,"type":59},10,"ESTIMATED","INTERVENTIONAL",[62],"NA","Cardiac resynchronization therapy（CRT） benefits a portion of patients, while more patients are not yet indicated to a therapy that mechanically helps the heart systole and\u002For diastole.
