Prescribing competence: The pros and cons of different methods for assessment

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...

Restricting excessive cardiac action potential and QT prolongation: a vital role for IKs in human ventricular muscle [PDF]

open access: yes, 2005
Background - Although pharmacological block of the slow, delayed rectifier potassium current (I-Ks) by chromanol 293B, L-735,821, or HMR-1556 produces little effect on action potential duration (APD) in isolated rabbit and dog ventricular myocytes, the ...

Aortic Dissection With Pseudoaneurysm Formation Masquerading as Pulmonary Embolism After Transcatheter Aortic Valve Replacement

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Transcatheter aortic valve replacement (TAVR) is a commonly performed procedure for the treatment of severe aortic stenosis. While it is generally considered a low‐risk procedure, one of the rare potentially life‐threatening complications includes aortic dissection.

Cardiac parasympathetic modulation in the setting of radiofrequency ablation for atrial fibrillation

open access: yesArchives of Medical Science, 2019
The cardiac autonomic nervous system plays an important role in the genesis and maintenance of atrial fibrillation. Although, pulmonary vein isolation is the cornerstone in today’s approach to atrial fibrillation ablation, a considerable proportion of ...

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]

open access: yes, 2019
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Redo‐Transcatheter Aortic Valve Replacement With a 26 mm Sapien Valve in a 26 mm Evolut Valve to Correct Significant Paravalvular Leak via Transcarotid Access

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT An 84‐year‐old man with multiple comorbidities including severe aortic stenosis, heart failure with a reduced ejection fraction, severe peripheral artery disease with prior bilateral iliac artery stents, and trifascicular block presented for evaluation for aortic valve replacement.

Intermittently “Pre-Excited” ECG after Accessory Pathway Ablation: Unsuccessful Procedure or a Complication?

open access: yesCase Reports in Cardiology, 2012
A 52-year-old woman with previously unsuccessful posteroseptal pathway ablation using radiofrequency energy presented with intermittently occurring short PR followed by a wide QRS complex, and complaining of palpitations with characteristics different ...

Transfemoral Transcatheter Aortic Valve Implantation (TF‐TAVI) for Patients With Left Ventricular Assist Device (LVAD) and Aortic Regurgitation

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic regurgitation (AR) develops in up to 25%−30% of patients with left ventricular assist device (LVAD). Treatment remains challenging since surgery confers significant peri‐operative risk and the lack of valvular calcification renders transfemoral transcatheter aortic valve implantation (TF‐TAVI) with non‐dedicated devices technically ...

A Predictive Model and Scoring System for All-Cause Mortality in Patients With Atrial Fibrillation Combined With Obstructive Sleep Apnea Syndrome: A Retrospective Case–Control Study

open access: yesReviews in Cardiovascular Medicine
Background: The high prevalence and mortality rate of combined atrial fibrillation (AF) and obstructive sleep apnea syndrome (OSAS) impose a significant disease burden on public healthcare systems. However, there is currently a lack of
