Early Stroke Volume Variation After Transcatheter or Surgical Aortic Valve Replacement Predicts Clinical Outcomes in Low‐Flow Aortic Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Little is known about stroke volume index (SVi) change and its prognostic implication in patients with low‐flow aortic stenosis (AS) undergoing aortic valve replacement (AVR) and conflicting results are present in literature. The aim of this study was to evaluate the postoperative change in SVi and its impact on outcomes in patients

Revascularization of a Saphenous Vein Graft Ostial Stenosis in a Patient With Marfan Syndrome and a Previous Bentall Procedure Who was Resuscitated From Ventricular Fibrillation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT A 24‐year‐old male with Marfan syndrome was admitted following an episode of ventricular fibrillation (VF) during exercise. He had previously undergone multiple aortic surgical procedures for symptomatic aortic regurgitation and an ascending aortic false aneurysm.

New model of ventricular fibrillation [PDF]

Journal of Electrocardiology, 2005
The purpose of this study was to develop a more efficient and stable model of ventricular fibrillation (VF) in the isolated rabbit heart, because there is not a satisfactory model with this animal. We also observed the effects of increasing extracellular calcium in the stability and reversibility of the arrhythmia.

Electrocardiographic R Wave Peak Time: Correlation With the Severity of Coronary Artery Disease and Prognosis in Patients With Acute Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Electrocardiographic parameters have emerged as valuable noninvasive markers for risk stratification in acute coronary syndrome (ACS). Aims This study aimed to evaluate the correlation between R wave peak time (RWPT) and coronary artery disease (CAD) severity, and to assess its prognostic value for in‐hospital major adverse cardiac ...

From Atrial Fibrillation to Ventricular Fibrillation and Back [PDF]

Circulation, 2015
A 27-year-old man without any previously known health conditions was found unresponsive on the street after he had been exercising. Cardiopulmonary resuscitation was started by bystanders. On arrival of the emergency services, the rhythm strip in Figure 1A was recorded.

Postprocedural Anticoagulation Following Primary Percutaneous Coronary Intervention for ST‐Segment Elevation Myocardial Infarction: A Meta‐Analysis of 47,310 Patients

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The use of procedural anticoagulation during primary percutaneous coronary intervention (PCI) is well established and has been shown to improve clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI).

Bioprosthetic Valve Fracturing in Valve‐in‐Valve TAVI: Clinical and Echocardiographic Outcomes in Failing Perimount Aortic Bioprostheses—A Multicenter Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data comparing clinical and hemodynamic outcomes of bioprosthetic valve fracturing (BVF) and “standard”‐postdilatation during valve‐in‐valve transcatheter heart valve implantation (ViV‐TAVI) are lacking. The authors aimed to analyze hemodynamic and clinical outcomes of BVF compared to “standard”‐postdilatation during ViV‐TAVI ...
