The semiquantitative Clinical Frailty Scale (CFS) is a simple tool to assess patients' frailty and has been shown correlate with mortality in elderly patients even when evaluated by nongeriatricians. aim of the current study was determine prognostic value CFS who underwent transcatheter aortic valve replacement.We utilized OCEAN (Optimized Catheter Valvular Intervention) Japanese multicenter registry review data 1215 replacement. Patients were categorized into 5 groups based on stages: 1-3,...
One of the final treatments for end-stage heart failure is transplantation. However, a shortage donor hearts has created long waiting list and limited benefits. Our ultimate goal to create whole beating fabricated on an organ scaffold human Here, we successfully performed first transplantation using decellularized porcine with mesenchymal stem cells. A was harvested following cardiac arrest induced by high-potassium solution stored at −80°C 24 h. The completely 1% sodium dodecyl sulphate...
Abstract OBJECTIVES We evaluated the operative and long-term outcomes of frozen elephant trunk (FET) technique for acute type A aortic dissection. METHODS This study 426 consecutive patients who underwent repair dissection from June 2007 to December 2018 at our centre. Of these, 139 total arch replacement with FET (FET group), 287 other procedures (no group). Ninety-two in group were matched 92 no by using propensity score matching analysis. RESULTS Thirty-day mortality neurological...
Abstract There has been an increasing number of secondary downstream aorta replacements following aortic arch repair using a frozen elephant trunk (FET). We present anastomosis technique to join graft prosthetic graft. The FET is inserted into the with continuous sutures, two-bite Dacron added side. This may prevent anastomotic leakage between two grafts.
Abstract The use of thoracic endovascular aortic repair (TEVAR) for aneurysm (TAA) and Stanford type B dissection (TBAD) has been increasing; however, in terms etiology, the differences long term after TEVAR outcomes remain unexplored. Thus, we investigated etiology-specific long-term results TAA TBAD. A total 421 procedures were performed at our institution from July 2007 to December 2021; 249 cases 172 TBAD included. Traumatic injury excluded. mean observation duration was 5.7 years....
We evaluated the operative and long-term outcomes of various approaches for aortic arch repair.A total 436 consecutive patients who underwent repair from January 2001 to March 2016 in our centre were evaluated. Of these, 276 conventional replacement (TAR), 118 thoracic endovascular (TEVAR). The remaining 42 staged (STEVAR). A 72 TEVAR group matched open surgery including TAR or STEVAR by using propensity score analysis.Surgical showed shorter ICU hospital stay ( P < 0.001 0.001,...
Spinal cord deficits are devastating complications after surgery for thoracic and thoracoabdominal aortic aneurysms. We developed a regional spinal cooling system using an epidural catheter containing cold saline within isolated counter-current lumen to prevent such reviewed the clinical results. enrolled 37 patients with (n = 13) 24) aneurysms that were repaired under mild hypothermia partial femoro-femoral bypass. Although 2 died before hospital discharge (hospital mortality, 5.4%), none...
We aimed to evaluate the incidence and midterm clinical outcomes of left ventricular obstruction (LVO) after transcatheter aortic valve implantation (TAVI).LVO is occasionally unmasked following replacement for severe stenosis. However, little known about prevalence effects LVO TAVI.A total 158 patients who underwent TAVI in our center between October 2013 November 2015 received echocardiographic evaluations at baseline; before hospital discharge; 3, 6, 12 months TAVI. was defined as a peak...
Total arch replacement (TAR) using an endovascular approach has been initially introduced as the frozen elephant trunk technique (FET). In our institute, TAR FET with Frozenix used first-line treatment for distal aortic aneurysms since 2014. This study aimed to evaluate early and long-term outcomes demonstrate efficacy of this procedure.Between 2014 2021, 121 consecutive patients were treated aneurysms. Early retrospectively analysed.The 30-day mortality rate was 2.5% (3/121). Of...
Background Although transcatheter aortic valve replacement ( TAVR ) is the least invasive treatment for patients with symptomatic stenosis, some hesitate to undergo procedure. We investigated clinical impact of delay after patient refusal . Methods and Results used Japanese OCEAN (Optimized Catheter valvular intervention) regsitry data 1542 who underwent Refusal was defined as at 1 time informed consent. Patients were separated into 2 groups: (28/1542, 1.8%) non-refusal (1514/1542, 98.2%)....
Background:The aims of the present study were to analyze anatomical characteristics type A aortic dissections (TAAD) in Japanese patients and evaluate feasibility 3 next-generation stent grafts dedicated ascending/arch lesions.
Abstract Medical management is the standard treatment of chronic type B aortic dissection (CTBAD). However, roles open surgical repair (OSR) and thoracic endovascular (TEVAR) in patients with CTBAD remain controversial. Thus, this study aimed to assess compare mid- long-term clinical outcomes OSR via left thoracotomy that TEVAR for CTBAD. The data 85 consecutive who underwent surgery from April 2007 May 2021 were retrospectively reviewed. divided into two groups: Group G, which included OSR,...
Abstract Background A ruptured thoracoabdominal aortic aneurysm (rTAAA) represents a considerable challenge for surgeons. To date, endovascular procedures have not been able to completely replace open repair when debranching is required. Case presentation 73-year-old man was admitted our hospital after complaining of left lateral abdominal pain. Enhanced computed tomography revealed retroperitoneal hematoma and large, Crawford type IV TAAA. We first performed emergency resuscitative surgery...
