Anesthetic management of a patient with severe aortic regurgitation undergoing reoperation for ascending aorta false aneurysm using hypothermia: prevention of ventricular fibrillation by nifekalant

JA Clinical Reports, 2021
Background To prevent cardiac collapse and to protect cerebral function, hypothermic cardiopulmonary bypass is established before resternotomy. However, ventricular fibrillation under hypothermia facilitates left ventricular distension, which causes ...

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.

A comparison of antiarrhythmic-drug therapy with implantable defibrillators in patients resuscitated from near-fatal ventricular arrhythmias.

New England Journal of Medicine, 1997
BACKGROUND Patients who survive life-threatening ventricular arrhythmias are at risk for recurrent arrhythmias. They can be treated with either an implantable cardioverter-defibrillator or antiarrhythmic drugs, but the relative efficacy of these two ...

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 ...

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.

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 ...
