Heart transplantation from donation after circulatory death (DCD) donors has the potential to substantially increase overall heart transplant activity. The aim of this report is review first 8 y our clinical program at St Vincent’s Hospital Sydney, describe how evolved and impact that changes retrieval protocols have had on posttransplant outcomes. Since 2014, we performed 74 DCD transplants utilizing a direct procurement protocol followed by normothermic machine perfusion. Changes resulted...
This study was performed to analyse the impacts of functional mitral stenosis (MS) following valve (MV) repair on late cardiac function and new onset atrial fibrillation or survival.We retrospectively reviewed 602 patients with regurgitation who underwent MV for Type II dysfunction from 2001. Functional MS diagnosed when mean transmitral pressure gradient (MTPG) ≥5 mmHg postoperative echocardiography. We analysed preoperative surgical risk factors (MS group). then compared long-term outcomes...
Background:This study evaluated the mid to long-term durability and hemodynamics of small-size Mosaic bioprosthesis, a third-generation stented porcine for aortic valve replacement (AVR).Methods Results:From 2000 2012, 207 patients (117 women; age, 74±8 years; body surface area, 1.48±0.25 m2) underwent AVR with bioprosthesis. The mean follow-up period was 3.5±2.7 years (maximum, 12.4 years) rate 93.7%. A 19-, 21-, 23-, 25-, 27-mm prosthesis used in 103, 53, 35, 13, 3 patients, respectively....
Background: The number of surgical aortic valve replacements using bioprosthetic valves is increasing, and newer may offer clinical advantages in Japanese patients, who generally require smaller replacement than Western patients. In this study we retrospectively evaluated the Trifecta Magna to compare outcomes hemodynamics a group
Background:Whether there is a significant difference in the long-term surgical outcomes between suture annuloplasty and ring for treatment of functional tricuspid regurgitation (TR) still controversial. We compared (TAP) with without an ring.
The presence of cerebral haemorrhage (CH) preoperatively is a risk factor in-hospital cerebrovascular complications post-valve surgery for acute infective endocarditis. However, factors related to in the long term are poorly understood. We reviewed series these patients investigate and long-term outcomes.An institutional 148 who underwent valve active endocarditis between 2000 2016 were enrolled. Patients divided into 2 groups based on preoperative CH:CH group (n = 25) non-CH 123). Of them,...
This study aimed to compare the hemodynamic performance and clinical results of EVAHEART HeartMate II left ventricular assist devices (LVADs). From 2007 2016, fourteen patients received 28 at our center. Early survival, driveline infection, neurologic events were evaluated. Hemodynamic was evaluated with transthoracic echocardiography right heart catheterization. Mean follow-up 35.5 ± 14.8 months for 29.8 6.5 II. Survival rates comparable between two groups. After 24 months, freedom from...
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...
We compared the frequency of immunoglobulin G (IgG) type human leukocyte antigen (HLA) class I antibodies between patients with systemic lupus erythematosus (SLE) and healthy controls using a highly sensitive FlowPRA method. Sixteen 130 normal males 2 10 females without history pregnancy (none had ever been transfused) possessed HLA antibodies. In SLE, male, but not female patients, showed significant increase in corresponding controls. The did appear to be involved development SLE because...
Background:Prosthesis-patient mismatch (PPM) is associated with increased mid-term and long-term mortality rates after aortic valve replacement (AVR). This study aimed to evaluate the efficacy of Carpentier-Edwards Perimount Magna Ease (CEPMs) bioprostheses reduce incidence PPM.
Despite the cosmetic benefits of minimally invasive approach for mitral disease, clinical benefit and risk are not fully known. We investigated valve (MV) repair type II dysfunction using propensity score-matched analysis. Methods Results: Since 2001, 602 patients have undergone MV (464 with conventional median sternotomy 138 approach). One-to-one matched analysis estimated score based on 23 factors resulted in 93 well-matched patient pairs. There was no in-hospital death both groups. The...
The natural course of myocardial calcification is unclear. We herein report a case massive biventricular associated with fulminant myocarditis and present its course. patient was 15-year-old boy. Massive detected in both ventricles on computed tomography several months after left ventricular assist device placement. Although the gradually regressed, patient's cardiac function did not recover, he underwent heart transplantation waiting period 3 years. A histological examination revealed...
Coronary artery disease (CAD) after heart transplantation (HTx) develops as a combination of donor-transmitted coronary atherosclerosis (DTCA) and cardiac allograft vasculopathy. Assessing donor CAD before procurement is important. Because calcification (CAC) predictor for CAD, donor-heart CAC usually evaluated to estimate the risk CAD. The usefulness predicting DTCA, however, not known. Methods Results: Sixty-four HTx recipients whose underwent chest computed tomography or ≤2 weeks who...
In patients undergoing transcatheter aortic valve replacement (TAVR) for severe stenosis (AS), a sigmoid septum, characterized by subaortic interventricular hypertrophy, often results in the need new pacemaker implantation (PMI). this study, we reviewed feasibility and treatment efficacy of TAVR AS with septum. Methods Results: Between 2011 2016, 48 (25.4%; mean age 84.9±5.4 years; 9 males) septum 141 (74.6%; 82.9±5.5 61 without underwent TAVR. Their operative outcomes, echocardiographic...
Heart transplantation (HTx) is reported to have a comparable effect on the prognosis of heart failure patients without muscular disease and for those with dystrophy (MD). However, little known about changes in diseases MD after HTx.
The best management strategy for patients with coronary disease and mild to moderate AS requires the clinician consider operative risks of isolated artery bypass grafting (CABG) against untreated aortic stenosis (AS).Between 2000 2014, off-pump CABG (OPCAB) was performed in 2023 patients. Of these patients, 103 presented or (mean age 72.7±6.3 years; 23 females), 96 (93.2%) seven (6.8%) AS. We compared long-term outcome undergoing OPCAB 13 who (CAD) underwent concomitant valve replacement...
We aimed to elucidate the clinical relevance of transcranial Doppler (TCD) in detection microembolic signals patients with Heartmate II (HM-II). Twenty HM-II underwent TCD examinations, and were rarely detected stable patients. However, they hemolysis and/or thromboembolic events. Further, examination under oxygen inhalation revealed that, both, solid emboli gaseous exist HM-II.
