Transient internal mammary artery graft stenosis on early angiography: navigating pitfalls in hybrid myocardial revascularization.

Objectives: Left internal mammary artery (LIMA) graft stenoses detected at early coronary angiography may be reversible and consequently prompt unnecessary graft revision. We aim to investigate the frequency, natural course, and clinical significance of internal mammary artery graft stenosis upon early angiography in patients undergoing hybrid myocardial revascularization.

Methods: In this retrospective sub-study of the Coronary Hybrid Revascularization Study, we compared graft appearance, ie, stenosis degree and flow, on early (in-hospital) and scheduled follow-up coronary angiography after 1 year.

Outcomes of isolated tricuspid valve surgery in contemporary practice.

Objectives: Isolated tricuspid valve (TV) surgery is rarely performed and has been associated with high mortality and morbidity. The aim of this study was to describe the clinical outcome and functional capacity following isolated TV surgery in contemporary practice.

Methods: We conducted a retrospective cohort study including all patients who underwent isolated TV surgery at our institution from 2013 to 2019.

[Trikuspidalklapinsufficiens].

Tricuspid regurgitation (TR) has in recent literature been described as an independently progressive disorder associated with a poor prognosis. Studies have emphasized the importance of a more proactive approach in treating TR in order to prevent progression of right ventricular dysfunction and ultimately right heart failure. These findings have renewed interest in surgical treatment for isolated TR whilst also fueling rapid advancements in transcatheter therapies, as argued in this review.

Pacemaker Lead-Induced Tricuspid Valve Stenosis?

• Tricuspid valve stenosis following pacemaker implantation is rare. • Advanced echocardiography can identify the cause. • Invasive hemodynamic evaluation can quantify the effects.

Tricuspid annular plane systolic excursion is significantly reduced during uncomplicated coronary artery bypass surgery: A prospective observational study.

Objectives: Longitudinal shortening constitutes most of the right ventricle (RV) contraction in the normal heart. However, after even uncomplicated cardiac surgery with preserved RV function a significant and sustained decrease in longitudinal contraction expressed as a reduction in tricuspid annular plane systolic excursion (TAPSE) has been observed. Why and exactly when this happens remains unsettled.

Acute Pulmonary Embolism in a National Danish Cohort: Increasing Incidence and Decreasing Mortality.

This study reports the incidence, clinical profile and mortality for acute pulmonary embolism (PE) patients in the Danish population in four eras from 2004 to 2014. Patients admitted with first-time acute PE from 2004 through 2014 were identified from national patient registries classified according to the International Classification of Diseases, 10th edition, World Health Organization. A total of 30,275 patients from a population of 4,301,673 adult residents aged 18 years or older were diagnosed with first-time acute PE, corresponding to an incidence of 64 (95% confidence interval: 61-66) per 100,000 adult residents per year.

Surgical embolectomy compared to thrombolysis in acute pulmonary embolism: morbidity and mortality.

Objectives: The aim of this study was to investigate the long-term outcome after acute high- and intermediate-risk pulmonary embolism (PE) treated with surgical embolectomy or thrombolysis.

Methods: Prospective follow-up including assessment of 30-day and 5-year mortality. Clinical evaluation including ventilation/perfusion scintigraphy by single-photon emission computed tomography in combination with X-ray computed tomography, measurement of pulmonary diffusion impairment, spirometry and echocardiography.

Coagulopathy in patients with acute pulmonary embolism: a pilot study of whole blood coagulation and markers of endothelial damage.

Whole blood coagulation and markers of endothelial damage were studied in patients with acute pulmonary embolism (PE), and evaluated in relation to PE severity. Twenty-five patients were enrolled prospectively each having viscoelastical analysis of whole blood done using thrombelastography (TEG) and Multiplate aggregometry. Fourteen of these patients were investigated for endothelial damage by ELISA measurements of Syndecan-1 (endothelial glycocalyx degradation), soluble endothelial Selectin (endothelial cell activation), soluble Thrombomodulin (endothelial cell injury) and Histone Complexed DNA fragments (endothelial cytotoxic histones).

Transit-time flow measurement as a predictor of coronary bypass graft failure at one year angiographic follow-up.

Background: Transit-time flow measurement (TTFM) is a commonly used intraoperative method for evaluation of coronary artery bypass graft (CABG) anastomoses. This study was undertaken to determine whether TTFM can also be used to predict graft patency at one year postsurgery.

Methods: Three hundred forty-five CABG patients with intraoperative graft flow measurements and one year angiographic follow-up were analyzed.

[Patients with acute critical pulmonary embolism should be evaluated and treated in a centre with medical and surgical possibilities].

Acute pulmonary embolism (PE) is a common and potential lifethreatening condition. Nevertheless the advancements in the patient visitation and treatment algorithms have been few and the mortality unchanged high. Acute high risk PE, which is the most serious subtype, is primary treated with trombolysis.

Simulation-based training for thoracoscopy.

Introduction: An increasing proportion of thoracic procedures are performed using video-assisted thoracic surgery. This minimally invasive technique places special demands on the surgeons. Using simulation-based training on artificial models or animals has been proposed to overcome the initial part of the learning curve.

Surgical treatment of acute pulmonary embolism--a 12-year retrospective analysis.

Objectives: Surgical embolectomy for acute pulmonary embolism (PE) is considered to be a high risk procedure and therefore a last treatment option. We wanted to evaluate the procedures role in modern treatment of acute PE.

Design: All data on patients treated with surgical embolectomy for acute PE were retrieved from our clinical database.

Reliable and valid assessment of performance in thoracoscopy.

Background: As we move toward competency-based education in medicine, we have lagged in developing competency-based evaluation methods. In the era of minimally invasive surgery, there is a need for a reliable and valid tool dedicated to measure competence in video-assisted thoracoscopic surgery. The purpose of this study is to create such an assessment tool, and to explore its reliability and validity.

[Recurring pneumothorax due to traumatic rupture of the diaphragm].

We present a case where a patient is diagnosed with a traumatic right-sided diaphragmatic rupture ten years after the trauma, after eight incidences of pneumothorax and two thoracoscopic operations. Ten years before the current case, the female patient was the victim of a blunt thoraco-abdominal trauma. In the following years, she had recurrent right-sided pneumothorax and no effect of thoracoscopic surgery.
