Medical device recalls have called attention to the device approval process in the United States. The premarket approval (PMA) process requires clinical trials to evaluate safety and effectiveness, whereas the…
The relation between the incidence and severity of acute kidney injury (AKI) and clinical outcomes remains unclear in patients with DeBakey type III acute aortic dissection (AAD). We retrospectively assessed…
The left ventricular (LV) volumes, ejection fraction (EF), and dyssynchrony indexes for the 16 and 12 cardiac segments (Tmsv16-SD and Tmsv12-SD, respectively) were analyzed among nonadult, anthracycline-exposed long-term survivors of…
The ratio of early transmitral flow velocity (E) to mitral annular velocity (E′) is considered a predictor of pulmonary capillary wedge pressure (PCWP). In a previous small study, the paradoxical…
Peter Kowey was born in Norristown, Pennsylvania, January 4, 1950, and that is where he grew up. He graduated from Bishop Kendrick High School in June 1967 as Salutatorian and…
This study evaluated 2-dimensional (2D) transthoracic echocardiography (TTE) using Valve Academic Research Consortium–2 (VARC-2) criteria and 3-dimensional (3D) TTE for assessment of aortic regurgitation (AR) after transcatheter aortic valve implantation…
Factors correlating to mitral annulus calcification (MAC) include risk factors predisposing to atherosclerosis. In patients with mitral valve (MV) prolapse (MVP), other anatomic or mechanical factors have been supposed to…
The mechanism and tachycardia circuit of verapamil-sensitive atrial tachycardia originating from the atrioventricular annulus (AVA-AT) other than the atrioventricular node vicinity are not well clarified. In 23 patients, we examined…
Neopterin is synthesized by macrophages upon stimulation with gamma-interferon, and high neopterin production is associated with cellular immune activation and increased production of reactive oxygen species (oxidant stress), but the…
Risk stratification tools used in patients with severe aortic stenosis have been mostly derived from surgical series. Although specific predictors of early mortality with transcatheter aortic valve replacement (TAVR) have…
