Platelet Volume Parameters as Predictors of Valvular Thrombosis Risk in Patients with Aortic and Mitral Valve Replacement.
Clin Appl Thromb Hemost

Cardiovascular Research Institute, Tehran Heart Center, Tehran University of Medical Sciences, Tehran, Iran.
Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy.

September 2023
Division of Cardiac Surgery, Department of Surgery, University of Chicago, Chicago, Illinois.
Background: Patient-specific, 3-dimensional printed, tissue engineered vascular grafts (3DTEVGs) are manufactured to optimize hemodynamic performance and to accommodate growth. We evaluate growth outcomes of 3DTEVGs compared with standard grafts for pulmonary artery reconstruction in porcine models.
Methods: Magnetic resonance imaging (MRI) with 4-dimensional flow data was acquired in porcine models (n = 8).
Five-Year Outcomes of Hybrid Arch Frozen Elephant Trunk Repair With Novel Multibranched Hybrid Graft.

December 2023
Division of Cardiac Surgery, Western University, London Health Sciences Centre, London, Ontario, Canada.
Background: The objective of this study was to report the 5-year outcomes of hybrid arch frozen elephant trunk (FET) procedures with a multibranched hybrid graft.
Methods: Between 2014 and 2020, 50 consecutive patients (63 ± 15 years old; 34% women) underwent hybrid arch FET with Thoraflex hybrid graft (Terumo Aortic) at a single center. Indications included aortic aneurysm (n = 48 [96%]), acute aortic dissection (n = 10 [20%]), and chronic dissection (n = 20 [40%]).
Rapidly Enlarging Abdominal Aortic Aneurysm Requiring Endovascular Repair After LVAD Placement.

Center for Advanced Cardiac Care, Columbia University Irving Medical Center, New York, New York.
A 67-year-old man with medical history of ischemic cardiomyopathy with stage D heart failure and infrarenal abdominal aortic aneurysm underwent implantation of a left ventricular assist device (LVAD). Three months after the procedure, he presented with unrelenting back pain and a rapidly increased in size aneurysm. The patient underwent urgent endovascular aneurysm repair with uncomplicated recovery.

Department of Thoracic Surgery, Vanderbilt University Medical Center, Nashville, Tennessee.
A 44-year-old man with a history of facioscapulohumeral muscular dystrophy and pectus excavatum presented with multiyear history of progressive, severe respiratory dysfunction, pain, recurrent respiratory infection, and chest wall deformity. With bioprosthetic engineers, the surgical team customized a 3-dimensional printed model of a sternal implant interacting with the patient's anatomy. After approval from the Food and Drug Administration, the customized sternal plates were created and implanted in a sternal reconstruction operation.
