  1. 1. Evaluation and prognostic significance of premature ventricular contractions in patients without structural heart disease

    Author : Raffaele Scorza; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Introduction: Premature ventricular contractions (PVCs) are a common form of arrhythmia associated with poor prognosis in patients with structural heart disease. However, their prognostic impact on healthy individuals is unclear. READ MORE

  2. 2. Assessment of Left Ventricular Dysfunction and Remodelling by Determination of Atrioventricular Plane Displacement and Simplified Echocardiography

    Author : Ronnie Willenheimer; Kardiologiska klinikens forskargrupp; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; simplified echocardiography; atrioventricular plane displacement; diagnosis; screening; heart failure; prognostication; latent heart failure; left ventricular dysfunction; Kardiovaskulära systemet;

    Abstract : Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. READ MORE

  3. 3. New Intraoperative Techniques to Improve Advanced Aortic Root Surgery

    Author : Faleh Alrashidi; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Modified Ross Operation; Aortic Root surgery; Microemboli signals MES ; Transcranial Doppler TCD ; Acute plateletphersis APP ; Transesophageal echocardiography TEE ; de-airing;

    Abstract : Study I: Thirteen patients underwent a modified Ross operation in which the free-standing pulmonary autograft was supported externally by a Dacron vascular prosthetic jacket (DVPJ). The tailor-made DVPJ prevented dilatation of the neo-aortic root significantly following a median follow-up of 47 months compared to a cohort of l3 matched patients undergoing conventional Ross operation.

  4. 4. Gas Embolism in Laparoscopic Liver Surgery

    Author : Diddi Fors; Sten Rubertsson; Dag Arvidsson; Tor Inge Tønnessen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopic liver; CVP; PEEP; high frequency jet ventilation; cardiopulmonary physiology; carbon dioxide; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

    Abstract : Laparoscopic liver surgery is complicated due to the structure of this organ with open sinusoids. A serious disadvantage is the risk of gas embolism (GE) due to CO2 pneumoperitoneum. CO2 can enter the vascular system through a wounded vein. A common opinion is that gas fluxes along a pressure gradient, e. READ MORE

  5. 5. Cardiac muscle injury in children and experimental animals. Reflections in ECG, especially high-resolution electrocardiography

    Author : Rolf Bennhagen; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Kardiovaskulära systemet; Cardiovascular system; signal-averaging ECG; ischaemia; cardiac transplantation; Pediatri;

    Abstract : Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. READ MORE
