One-Year and Five-Year Outcomes of Transcatheter Aortic Valve Replacement or Surgical Aortic Valve Replacement in a Taiwanese Elderly Population.

Background: The aim of our study was to provide real-world data on outcomes for elderly Taiwanese patients who underwent transcatheter aortic valve replacement or surgical aortic valve replacement in different risk groups.

Methods: From March 2011 through December 2021, 177 patients with severe aortic stenosis who were ≥70 years old and had undergone TAVI (transcatheter aortic valve implantation) or SAVR (surgical aortic valve replacement) in a single center were divided by STS score (<4%, 4-8% and >8%) into three different groups. Then, we compared their clinical characteristics, operative complications, and all-cause mortality.

Concomitant Hepatectomy and Atrial Thrombectomy under Cardiopulmonary Bypass versus Staged Hepatectomy in the Treatment for Hepatocellular Carcinoma with Large Right Atrial Tumor Thrombi.

(1) Background: Hepatocellular carcinoma (HCC) with a large right atrium tumor thrombus (RATT) is a rare and critical presentation. Emergency hepatectomy and thrombectomy under cardiopulmonary bypass (CPB) is life-saving and potentially curative. The aim of this study is to propose an appropriate approach for this condition.

Long-term results of robotic-assisted coronary artery bypass grafting with composite arterial grafts for multiple coronary anastomoses: 10-year experience.

Currently, robotic-assisted coronary artery bypass grafting (RACABG) is a feasible choice for myocardial revascularization. Acceptable outcomes have been reported for RACABG with single target vessels; however, the long-term benefits of multivessel RACABG with composite arterial grafts have rarely been studied. Therefore, our study investigated the long-term results of multivessel RACABG with composite arterial grafts by reviewing the clinical data of patients from Taichung Veterans General Hospital.

Case Report: Leaflet Thrombosis After Transcatheter Aortic Valve Replacement With Worsening Heart Failure-A Successful Resolution Using Non-vitamin K Antagonist Oral Anti-coagulant.

Transcatheter aortic valve replacement (TAVR) is indicated for treating symptomatic severe aortic valve stenosis (AS) with intermediate-to-high surgical risks. Few reports are available on managing leaflet thrombosis after TAVR with worsening heart failure. A 77-year-old man with severe AS and coronary artery disease (CAD) received a successful TAVR with Edwards Sapien 3 valve.

Transcarotid Transcatheter Aortic Valve Replacement in an Octogenarian With Complex Type B Aortic Dissection and Aneurysm: A Case Report.

We report the case of an octogenarian with severe aortic valve stenosis, chronic kidney disease (CKD) and heart failure. Due to advanced CKD, we used a 3-dimensional transesophageal echocardiogram for sizing the device before transcatheter aortic valve replacement (TAVR). Noncontrast computed tomography found complex aortic dissection involving the arch, descending thoracic aorta, and abdominal aorta.

Effect of Retrograde Cerebral Protection Strategy on Outcome of Patients with Stanford Type A Aortic Dissection.

Background: Neurological complications are an important concern in the repair of type A aortic dissection. Supra-aortic involvement is considered to be an important risk factor for neurological injuries. However, the optimal brain protection strategy still remains controversial.

Glitazones and alpha-glucosidase inhibitors as the second-line oral anti-diabetic agents added to metformin reduce cardiovascular risk in Type 2 diabetes patients: a nationwide cohort observational study.

Objective: Metformin is the standard first-line drug for patients with Type 2 diabetes (T2DM). However, the optimal second-line oral anti-diabetic agent (ADA) remains unclear. We investigated the cardiovascular risk of various ADAs used as add-on medication to metformin in T2DM patients from a nationwide cohort.

A Rare and Life-Threatening Complication of Infective Endocarditis: Pseudoaneurysm of the Mitral - Aortic Intervalvular Fibrosa.

Unlabelled: A 59 year-old previously healthy male was admitted to the hospital with fever reportedly several days in duration. His physical examination was unremarkable at first. Pneumonia was initially diagnosed, but acute pulmonary edema with a new grade III to and fro murmur developed 1 week later.

Consecutive Sessions of Rescue Balloon Aortic Valvuloplasty for Critical Aortic Valve Stenosis Followed by Successful Bridging to Trans-Catheter Aortic Valve Implantation.

Unlabelled: Percutaneous balloon aortic valvuloplasty (BAV) was a rare procedure in catheterization laboratories because of its limited prognostic impact. The recent advent of transcatheter aortic valve implantation (TAVI) has led to a resurgence of BAV, opening the way to a new indication as a bridge to TAVI. Herein, we reported an 83-year-old man with critical aortic valve stenosis and pulmonary edema, who strongly declined surgical aortic valve replacement.

Excellent mid-term durability of the On-X mechanical aortic valve in the pulmonary position with a low international normalized ratio.

Background And Aim Of The Study: Although the pulmonary position has been preferred for the placement of homografts or bioprosthetic valves, the limited longevity of these implants makes reoperation almost unavoidable. Good durability of mechanical valves in the pulmonary position has been reported. The mid-term outcomes were analyzed of patients who received an On-X mechanical heart valve for pulmonary valve replacement (PVR) with a relatively low International Normalized Ratio (INR).

Cardiac repair with injectable cell sheet fragments of human amniotic fluid stem cells in an immune-suppressed rat model.

Direct intramyocardial injection of the desired cell types in a dissociated form is a common route of cell transplantation for repair of damaged myocardium. However, following injection of dissociated cells, a massive loss of transplanted cells has been reported. In this study, human amniotic fluid stem cells (hAFSCs) were used as the cell source for the fabrication of cell sheet fragments, using a thermo-responsive methylcellulose hydrogel system.

Cellular cardiomyoplasty with human amniotic fluid stem cells: in vitro and in vivo studies.

Human amniotic fluid stem cells (hAFSCs) derived from second-trimester amniocentesis were evaluated for the therapeutic potential of cardiac repair. Whether hAFSCs can be differentiated into cardiomyogenic cells and toward the maturation of endothelial cell lineage was investigated in vitro using mimicking differentiation milieu. Employing an immune-suppressed rat model with experimental myocardial infarction, an intramyocardial injection was conducted with a needle directly into the peri-infarct areas.

Occlusion of hepatic blood inflow for complex central liver resections in cirrhotic patients: a randomized comparison of hemihepatic and total hepatic occlusion techniques.

Background: Intermittent occlusion of hepatic blood inflow by means of a hemihepatic or total hepatic occlusion technique is essential for reducing operative blood loss. Central liver resection to preserve more functioning liver parenchyma is mandatory for centrally located liver tumors in patients with cirrhosis, but it requires a longer overall hepatic ischemic time because of a wide transection plane. No controlled comparison has been performed for the 2 techniques in these operations.
