Balloon-Expandable Vs Self-Expanding Valves for Transcatheter Aortic Valve Implantation in Internally Stented Surgical Valves

Daisuke Sato, Noriaki Moriyama, Yoichi Sugiyama, Hirokazu Miyashita et autres

Background Internally stented (IS) surgical valves, such as Mitroflow and Trifecta, are known to carry an elevated risk for coronary artery obstruction during Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) procedures. The data of comparison between balloon-expandable valves (BEV) and supra-annular self-expanding …

Safety and Prognostic Implications of Mechanical Circulatory Support‐Assisted Transcatheter Edge‐to‐Edge Repair: The OCEAN‐Mitral Registry

Shuhei Tanaka, Teruhiko Imamura, Makiko Nakamura, Nobuyuki Fukuda et autres

Background Transcatheter edge‐to‐edge repair of the mitral valve (M‐TEER) has demonstrated promising outcomes for patients with mitral regurgitation who are unsuitable for surgical intervention. However, the clinical implications of M‐TEER in patients requiring mechanical circulatory support (MCS) for unstable hemodynamics remains unclear. …

Real‐World Outcomes of the Initial Clip Selection for Transcatheter Edge‐to‐Edge Repair Using the MitraClip G4 From the Optimized Catheter Valvular Intervention‐Mitral Registry

Shunsuke Kubo, Masanori Yamamoto, Mike Saji, Masahiko Asami et autres

Background The association of outcomes with initial clip selection has not been investigated in patients undergoing transcatheter edge‐to‐edge repair with the MitraClip G4. Methods We analyzed 2257 patients receiving the MitraClip G4 according to the initial clip type: short (NT/NTW) versus long …

Left Ventricular Free Wall Rupture or Aortic Dissection

Daisuke Sato, Takashi Matsumoto, Motoki Nagatsuka, Tohru Asai et autres

CASE SUMMARY: Aortic dissection and left ventricular (LV)wall rupture after acute myocardial infarction can both be life-threatening. Furthermore, it is difficult to distinguish between aortic dissection and acute myocardial infarction due to similar clinical presentation. Herein, we present the case of a …

Clinical and hemodynamic outcomes for transcatheter aortic valve implantation in internally stented surgical valve -Comparison of Balloon- and Self-Expandable Valves-

Daisuke Sato, Noriaki Moriyama, Yoichi Sugiyama, Hirokazu Miyashita et autres

Abstract Background Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is indicated in patients undergoing repeat interventions for degenerative aortic valve bioprostheses. Patients with internally stented surgical valves (IS) (Mitroflow and Trifecta) are at a high risk for coronary artery obstruction during the …

Eosinophilic Myocarditis With Cerebral Infarction

Daisuke Sato, Takuya Kakutani, Masashi Yamaguchi, Shigeru Saito

Cerebral infarction in patients with eosinophilic myocarditis (EM) is a rare but serious complication. Although the major cause is the presence of intraventricular thrombus, the details remain unexplored. We illustrate a case of EM complicated by cerebral infarction, and we ascertained the …

Serial Imaging Follow-Up After the Diagnosis of Infectious Aortitis

Daisuke Sato, Noriaki Moriyama, Futoshi Yamanaka, Shigeru Saito

A 76-year-old man with methicillin-sensitive Staphylococcus aureus infection was admitted to the hospital with protracted fever and vomiting. Although computed tomography (CT) at the time of hospitalization was unremarkable, 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT revealed a focal FDG uptake with …

Left Bundle Branch Area Pacing With TAVR

Daisuke Sato, Noriaki Moriyama, Mikko Jalanko, Futoshi Yamanaka et autres

We illustrate a successful case of left bundle branch area pacing with contemporary transcatheter aortic valve replacement. The association between the position of the transcatheter heart valve and the cusp-overlap view may be used to effectively identify the targeted left bundle branch …

Autopsy Findings of Late Coronary Occlusion After TAVR-in-SAVR With Chimney Stenting

Daisuke Sato, Mikko Jalanko, Tommi Vähäsilta, Mika Laine

IMAGE(S): CT imaging/autopsy findings were used for this study. CASE SUMMARY: An 87-year-old woman developed late coronary artery occlusion after transcatheter aortic valve replacement (TAVR) with chimney stenting. Coronary angiography failed to achieve selective cannulation of the left coronary artery, and wiring …

Differential neurogenic patterns underlie the formation of primary and secondary areas in the developing somatosensory cortex

Naoto Ohte, Takayuki Kimura, Yuta Furusho, Daisuke Sato et autres

The cerebral cortex consists of hierarchically organized areas interconnected by reciprocal axonal projections. However, the coordination of neurogenesis to optimize neuronal production and wiring between distinct cortical areas remains largely unexplored. The somatosensory cortex plays a crucial role in processing tactile information, …

A U-turn wiring technique for reverse-angled branches adjacent to ectasia: a case series

Masashi Yamaguchi, Yutaka Tanaka, Daisuke Sato, Shigeru Saito

Background: The reverse-wiring technique (RWT) using a hairpin-bend wire is useful for percutaneous coronary intervention of a bifurcation lesion with an extremely angulated side branch (SB); however, it is not necessarily effective in some anatomical situations. We report a novel SB wiring …
