BACKGROUND: The primary objective of this study was to identify specific factors in pediatric cardiac surgical patients when tracheal extubation was performed on the operating table after completion of open-heart surgery (Group-1), postoperatively in the intensive care unit within 6 h (Group-II) or after 6 h (Group-III). The causes of failed extubation, the presence of chromosomal disorders in addition to arterial blood gas analysis parameters at the time of tracheal extubation, and the duration of intensive care unit stay were also evaluated in each group...

BACKGROUND AND OBJECTIVES: Cardiovascular diseases (CVD) are associated with substantial psychological effects that can adversely influence long term prognosis. The aim of this study was to determine the psychological effect of the first hospital admission for acute coronary syndrome (ACS) or congestive heart failure (CHF) in an adult Omani population. METHODS: This cross-sectional questionnaire based study used the Hospital Anxiety and Depression Scale. Patients were recruited from the in-patient cardiology and medical wards of our institution...

BACKGROUND: The Lung Allocation Score (LAS) prioritises lung transplantation candidates, balancing waitlist mortality and post-transplant survival. The score groups sarcoidosis candidates based on mean pulmonary artery pressure: those with ≤30 mmHg (sarcoidosis A) are grouped with COPD and those with >30 mmHg (sarcoidosis D) with idiopathic pulmonary fibrosis (IPF). We hypothesise that sarcoidosis candidates have a higher waitlist mortality than other candidates within their LAS grouping...

BACKGROUND: The Lung Allocation Score (LAS) system was designed to equalize and minimize waitlist mortality among candidiates for lung transplantation. The LAS stratifies sarcoidosis patients by mean pulmonary arterial pressure (mPAP) into group A (mPAP ≤30 mm Hg) and group D (mPAP >30 mm Hg). In this study, we aimed to analyze the effect of diagnostic grouping and patient characteristics on waitlist mortality among sarcoidosis patients. METHODS: This was a retrospective review of sarcoidosis lung transplantation candidates since LAS implementation in May 2005 through May 2019 in the Scientific Registry of Transplant Recipients database...

BACKGROUND: The role of lung transplantation for coronavirus disease 2019 (COVID-19)-related lung failure is evolving as the pandemic persists. METHODS: From January 2021 to April 2022, 20 patients (median age 62 y; range 31-77) underwent lung transplantation for COVID-related lung failure at our institution. We reviewed their clinical and intraoperative characteristics and early outcomes including postoperative complications. RESULTS: Eleven patients (55%) had chronic lung disease when they contracted COVID-19...

BACKGROUND: Without aggressive treatment, pulmonary arterial hypertension (PAH) has a 5-year mortality of approximately 40%. A patient's response to vasodilators at diagnosis impacts the therapeutic options and prognosis. We hypothesized that analyzing perfusion images acquired before and during vasodilation could identify characteristic differences between PAH and control subjects. METHODS: We studied 5 controls and 4 subjects with PAH using HRCT and 13 NN PET imaging of pulmonary perfusion and ventilation...

The saphenous vein is the most used conduit for coronary artery bypass surgery. However, the patency rate of this graft is inferior to the internal thoracic artery patency rate, which is the gold standard. Using the conventional technique, the saphenous vein is harvested via a large open incision and excised in such a way that causes both vascular damage and wound healing complications. Consequently, vein graft patency and surgical site infection may be compromised. Graft patency is markedly improved when the saphenous vein is harvested atraumatically with minimal damage and with surrounding cushion of perivascular fat intact...

BACKGROUND: Although double lung transplant is recommended in patients with severe secondary pulmonary hypertension (SPH), our institutional experiences suggest a role for single lung transplant in these patients. Here, we review our experience prioritizing single lung transplant in patients with SPH to minimize their surgical burden. METHODS: We conducted a retrospective review of our lung transplant database to identify patients with SPH who underwent single lung transplant...

BACKGROUND: Pulmonary hypertension (PH) causes increased morbidity and mortality in patients with interstitial lung diseases (ILD). Classification schemes, while well-characterised for the vasculopathy of idiopathic PH, have been applied, unchallenged, to ILD-related PH. We evaluated pulmonary arterial histopathology in explanted human lung tissue from patients who were transplanted for advanced fibrotic ILD. METHODS: Lung explants from 38 adult patients who underwent lung transplantation were included...

PURPOSE: Venous thromboembolism (VTE) is a frequent complication after lung transplantation. Most VTE occur within 30 days of surgery and consist primarily of upper extremity deep venous thrombosis (DVT). Prior studies have described incidence rates of up to 43%, which is much higher than in other solid organ transplantation. VTE after lung transplantation has been associated with a lower survival post-transplant. Due to the morbidity and costs incurred by this complication, modifiable post-operative risk factors must be identified to improve our outcomes after lung transplantation...

Dual antiplatelet therapy is recommended in patients undergoing primary percutaneous coronary intervention (p-PCI) for ST-segment elevation myocardial infarction (STEMI). Pre-analytical variables may influence platelet function analysis results. Our aim was to evaluate the on-treatment platelet reactivity in peripheral artery vs coronary blood in patients with STEMI. We enrolled one hundred and nine patients who consecutively underwent p-PCI at Cardiology Unit of Padua University Hospital between June 2014 and June 2015...

INTRODUCTION: Coronary artery bypass graft (CABG) surgery remains the reference standard in the treatment of multivessel coronary disease. Several studies have shown that CABG with bilateral internal mammary arteries (BIMA) has better results in long-term survival. METHODOLOGY: A retrospective study was conducted on CABG surgeries with BIMA from January 2012 to December 2015 in the National Cardiovascular Institute, INCOR, EsSalud, Peru. The objectives were to determine the mortality and major cardiovascular events at 30 days follow-up...

Optimal management of multivessel coronary artery disease can be complex. We report a 67-year-old male patient who was admitted to the Padua University Hospital, Padua, Italy, in 2014 with a non-ST-elevation myocardial infarction. Coronary angiography showed diffuse multiple sub-occlusive lesions of the proximal and distal left coronary vessels involving a long segment of the vessel. On intravascular ultrasonography (IVUS), the left main artery was moderately diseased with critically stenotic and calcified branch ostia...

This study aims to develop and validate a new angiographic risk score to predict the risk of distal embolization (DE) during primary percutaneous coronary intervention (p-PCI) for ST-elevation myocardial infarction. Study included data from 1,200 patients who underwent p-PCI. The cohort was randomly split into a derivation cohort (n = 814) and a validation cohort (n = 386). Logistic regression was used to examine the relation between risk factors and the occurrence of DE. To each covariate in the model was assigned an integer score based on the regression coefficients...

BACKGROUND: Recent studies have described neo-atherosclerosis, developing inside the stent, as cause of very late stent thrombosis. CASE REPORT: A 59-year-old man, with family history of coronary artery disease, presented to our Department because of anterior ST-segment elevation myocardial infarction. Two years before he had underwent percutaneous coronary intervention with multiple drug-eluting stents (DES) implantation on proximal-mid left anterior descending artery (LAD), and mid-right coronary artery (RCA), respectively...

BACKGROUND: Coronary stent fracture is an under-recognized event but one that has been reported frequently in the drug-eluting stent era. Most reported cases of stent fracture occurred within days to two years after implantation, and are related to stent thrombosis and restenosis. CASE REPORT: Presentation of a 69-year-old male with a history of arterial hypertension and previous percutaneous coronary intervention (PCI), and with implantation of three overlapping drug-eluting stents (DES) on proximal-to-middle left anterior descending artery (LAD)...

Large thrombus burden (LTB) lesions in the context of primary percutaneous coronary intervention (p-PCI) have been related to unsuccessful angiographic reperfusion and unfavorable clinical outcomes. However, the hazard of LTB treatment on myocardial damage has not been evaluated. We investigated the impact of LTB on myocardial damage using contrast-enhanced cardiac magnetic resonance (CE-CMR) in the setting of p-PCI. In 327 patients, who underwent p-PCI without thrombus aspiration within 12 hours from symptom onset, we prospectively assessed the impact of LTB on infarct size and microvascular damage using CE-CMR...

OBJECTIVE: Our study aimed to support the viability of the concept of Ipsilateral Dual Kidney Transplantation (DKT) by presenting our initial experience and proposing a review of the literature in this subject. METHODS: Fifteen ipsilateral DKT were performed at Nice University Hospital between August 2010 and March 2012. We have described our skin incision preferences, the vascular anastomoses, and the uretero-vesical reimplantation. We have analyzed the operative duration, the cold ischemia time (CIT) of both transplants, the blood transfusion volume, the intraoperative and postoperative complications, the time to diuresis recovery, the hospital stay, and the kinetics of the creatinine clearance until the third postoperative month...
