Abstract and keywords OBJECTIVES Postinfarction left ventricular free-wall rupture (LVFRW) is a rare, unpredictable, often fatal complication of acute myocardial infarction. We reviewed our surgical experience with post-infarction LVFWR over 25 years to identify risk factors for in-hospital mortality. METHODS Seventy-two consecutive patients who underwent repair between 1994 2023 were retrospectively analyzed. The primary end-point was mean follow-up period 3.9 ± 5.4 (maximum years, 283...
A rapid deployment valve can shorten operation times and improve hemodynamics. However, explantation be challenging because of the unique structure such valves, including an inflow frame covered by textured sealing cloth beneath sewing cuff. In this case, we report a simple technique. This case involved 79-year-old woman with prosthetic endocarditis who had undergone aortic replacement 5 years earlier. Preoperative echocardiography revealed severe mitral regurgitation highly mobile mass on...
Fulminant myocarditis with cardiogenic shock requires extracorporeal life support (ECLS) and has poor outcomes. To improve outcomes, we have converted patients severely impaired cardiac multiorgan function from peripheral to central ECLS. In this study, reviewed these patients' clinical outcomes investigated associated factors.We retrospectively studied 70 consecutive fulminant under 2006 2020. Forty-eight underwent surgical conversion support, the remaining continued support. The end point...
To determine whether robotic mitral valve repair can be applied to more complex lesions compared with minimally invasive direct through a right thoracotomy.We enrolled 335 patients over 9-year period; 95% of the surgeries were performed after experience performing repair.The mean age in versus thoracotomy groups was 61 ± 14 vs 55 11 years, respectively (P < 0.001); 97% 100% patients, respectively, had degenerative aetiologies. Repair complexity simple 106 (63%) 140 (84%), 34 (20%) 20 (12%)...
Abstract Background Transcatheter aortic valve replacement (TAVR) has become widely used in recent years, However, there is also an increasing need for removal of TAVR valves due to prosthetic dysfunction (PVD) and the development infective endocarditis. Surgical (AVR) these patients risky original patient background anatomic conditions. Intuity rapid deployment (Edwards Lifesciences, Irvine, CA) would be useful such high risk prevent longer cardiac arrest time obtain good hemodynamic...
Background This study assessed risk factors for mitral regurgitation (MR) recurrence or functional stenosis during long-term follow-up in patients undergoing valve repair isolated posterior leaflet prolapse. Methods and Results We a consecutive series of 511 who underwent primary prolapse between 2001 2021. Annuloplasty using partial band was selected 86.3%. The resection technique used 83.0%, whereas the chordal replacement without 14.5%. Risk were analyzed MR ≥grade 2 with mean transmitral...
This study aimed to assess the long-term outcomes and investigate factors related left ventricular (LV) reverse remodelling after aortic valve replacement (AVR) in patients with chronic regurgitation (AR).
Abstract Objectives This study aimed to elucidate the mid-term outcomes and risk factors for recurrent mitral regurgitation after valve (MV) surgery atrial functional (AFMR). Methods results We retrospectively analyzed data of 50 consecutive patients (median age 74 years; 29 men) who underwent AFMR between January 2001 2019. Mean fibrillation duration was 12 years. During follow-up period 4.6 ± 4.4 years, 5 cardiac-related deaths were identified. Five- 10-year freedom from death rate all...
As an institutional strategy, the CryoMaze procedure has been established for treating atrial fibrillation (AF) since 2001. In this study, we aimed to analyse contemporary outcomes of and examine predictive factors successful sinus rhythm conversion.Between January 2009 March 2018, performed 352 procedures. The concomitant with other cardiac procedures were analysed by Kaplan-Meier method. logistic regression model was used predict risk recurrent AF.There no 30-day or in-hospital deaths all...
Abstract OBJECTIVES This study aimed to develop a novel risk score model for quantitative prediction of the rate atrial fibrillation (AF) recurrence after Cryo-Maze procedure in patients with persistent AF. METHODS We enrolled 450 consecutive who underwent AF concomitant other cardiac procedures our institute between 2001 and 2019. randomly divided cohort into two groups. derived ‘development cohort’ (270 patients; 60%) validated it ‘test (180 40%) by receiver operating characteristic curve...
Abstract Background Recent studies have reported atrial involvement and coexistence of aortic stenosis in transthyretin (ATTR) cardiac amyloidosis (CA). However, pathological reports extraventricular ATTR amyloid deposits structures or heart valves are limited, the clinical implications outside ventricles not fully elucidated. Case presentation We report 3 cases confirmed surgically resected left structures, all which were unlikely to significant infiltrating as determined by multimodality...
This study aimed to elucidate the short-term surgical outcomes and hemodynamics of Intuity valve compared standard bioprosthesis in Japanese patients.
The superiority of a fully magnetically levitated centrifugal-flow left ventricular assist device (LVAD) in terms overall survival, stroke events and pump thrombosis has been demonstrated previous international analyses, so we evaluated Japanese cohort for the same.
Although a bicuspid aortic valve (BAV) is known to be associated with progressive ascending dilatation, the fate of residual aorta after and surgery unknown. We reviewed surgical outcomes explored serial changes in size sinus Valsalva (SOV) distal (DAAo) 89 patients BAV undergoing replacement (AVR) graft (GR) aorta.We retrospectively examined who underwent AVR GR for BAV-and related disease thoracic dilatation at our institution between January 2009 December 2018. Patients alone or required...
Background:Since August 2015, the pediatric ventricular assist device (VAD), Berlin Heart EXCOR®, has been accepted for use in Japan.
