We evaluated the impact of patient-prosthesis mismatch (PPM) after mitral valve replacement on clinical outcomes using propensity score models.In all, 760 patients (aged 51 ± 12 years; male:female = 252:508) in whom was performed three types mechanical valves and two bioprosthetic were enrolled. In vivo data effective orifice area drawn from literatures PPM defined as an index 1.2 cm(2)/m(2) or less. The model used ways: inverse probability treatment weighting-adjusted multivariable...
Venovenous (VV) extracorporeal membrane oxygenation (ECMO) is a lifesaving technique for patients experiencing respiratory failure.When VV ECMO fails to provide adequate support despite optimal settings, alternative strategies may be employed.One option add another venous cannula increase drainage, while insert an additional arterial return assist cardiac function.Alternatively, separate circuit can implemented function in parallel with the existing circuit.We present case which method was...
The optimal timing for surgery in infective endocarditis (IE) with hemorrhagic stroke and neurologic deficits is difficult to decide because of the risk exacerbating provoking intracranial conversion after using cardiopulmonary bypass (CPB). This retrospective study aimed investigate impact presence or absence preoperative hemorrhage (ICH) on surgical outcomes IE recent stroke.The medical records all patients who underwent open heart active from February 2009 December 2020 were...
Atrial septal defect (ASD) is second common congenital heart disease that often leads to adult period. Intracardiac or transesophageal echocardiography (TEE) essential for percutaneous closure of ASD using Amplatzer occluder. Dexmedetomidine (DEX), which a highly selective α2-agonist, has sedative and analgesic properties without respiratory depression in the clinical dose range. We report with TEE under DEX sedation.
Abstract Atrial-esophageal fistula is an extremely rare disease and a life-threatening complication after catheter ablation for atrial fibrillation. There no consensus on the management or repair atrial-esophageal which has high mortality rate. Here, we describe lateral thoracotomy approach focused simplifying procedure in two patients.
: Hemolytic anemia after thoracic aortic surgery is rare. A 69-year-old female patient, who underwent ascending aorta replacement for acute type dissection 7 years ago, was transferred from another hospital due to hemolytic necessitating regular blood transfusions. After engaging in interdisciplinary discussions, we ruled out alternative medical diagnoses and treatments, ultimately identifying the kinked graft as primary cause of hemolysis. Due patient's comorbidity, it deemed high-risk...
Although unique aortic pathology related to bicuspid valve (BAV) has been previously reported, clinical implications of BAV aortopathy risk have yet be investigated. We looked for potential differences in matrix protein expressions the wall patients.Aorta specimens were obtained from 31 patients: group (n=27), tricuspid (TAV) (n=4). The was categorized into three subgroups: left coronary sinus-right sinus (R+L group; n=13, 42%), right sinus-non-coronary (R+N n=8, 26%), and anteroposterior...
Surgical management of interrupted aortic arch (IAA) with systemic outflow tract obstruction is clearly a challenge. If both ventricles are adequate, the Yasui operation useful option. Otherwise, staged approach through initial hybrid palliation and delayed biventricular repair, tailored to degree obstructed outflow, serves avoid high-risk neonatal procedure. Herein, we present patient IAA severe whose treatment involved palliation, followed by operation.
As a key strategy for achieving circular economy, remanufacturing involves bringing end-of-use (EoU) products or cores back to ‘like new’ condition, providing more affordable and sustainable alternatives new products. Despite the potential substantial resources energy savings, industry faces operational challenges. These challenges arise from uncertainties surrounding core quality functionality, return times, process variation required meet product specifications, values, as well their life...
In spite of the American Heart Association recommendations for blood pressure measurement, many physicians measure in only one arm that is easy to access at time measurement.This practice can lead incorrect management with significant interarm difference.We report a case 51 years old man who was scheduled undergo vascular bypass graft under combined spinal-epidural anesthesia.In 60 minutes after anesthesia, left dropped from 110/65 mmHg 74/45 mmHg.The still 80/50 two injections...
Abstract Background: The occurrence of type II endoleaks after repair endovascular aortic aneurysm has gradually gained increasing attention. We present a case patient with an expanding thoracic (TEVAR) for endoleak, in which successful direct ligation the intercostal artery was performed using sacotomy no cardiopulmonary bypass (CPB) or graft replacement. Case presentation: A 62-year-old male patient, previously treated TEVAR descending aneurysm, presented ongoing chest discomfort. Based on...
Biological valve prostheses in rapid-deployment aortic replacement (RD AVR) procedures have demonstrated excellent outcomes. However, previous studies indicate a lack of specific surgical outcomes for the bicuspid (BAV) or recommend RD AVR implementation. The existing literature comparing clinical and hemodynamic patients with BAV those tricuspid valves (TAVs) after is limited. Therefore, this study evaluated safety feasibility BAV, including Sievers type 0, compared early who underwent at...
The occurrence of type II endoleaks after endovascular repair aortic aneurysm has gradually gained increasing attention. We present a case patient with an expanding thoracic (TEVAR) for endoleak, in which successful direct ligations the intercostal artery were performed using sac incision without cardiopulmonary bypass (CPB) or graft replacement.
: Implantation of the left ventricular assist device (LVAD) has emerged as a widely employed therapeutic approach for specifically chosen individuals suffering from severe heart failure. Stroke is well-known complication LVAD implantation. Concomitant aortic surgeries in patients requiring implantation to avoid outflow graft anastomosis atherosclerotic aorta are unknown. We illustrate successful with hemiarch replacement atherosclerosis decrease risk postoperative stroke. A 72-year-old male...
Abstract Background Despite advances in surgical and postoperative care, myocardial injury or infarction (MI) is still a common complication patients undergoing coronary artery bypass surgery (CABG). Several studies that aimed to reduce injury, including those investigating statin loading, have been conducted but did not indicate any clear benefits. Evolocumab, PCSK9 inhibitor, has reported lower lipids prevent ischemic events various medical conditions. However, the effect of evolocumab...
Abstract Background Granulomatous inflammation results from various causes including infections and allergic reactions. It can appear as high signal intensity in T2-weighted or contrast-enhanced T1-weighted magnetic resonance imaging (MRI). Here, we describe a case of granulomatous looking like hematoma on an ascending aortic graft MRI. Case presentation A 75-year-old female was undergoing assessment for chest pain. She had history hemi-arch replacement dissection 10 years earlier. The...
Abstract Great saphenous vein is a conduit commonly used for coronary artery bypass grafting. However, several complications could occur at leg wound site harvesting. Here, we describe huge sac of hematoma as an uncommon complication harvest A 62-year-old gentleman was readmitted with swelling left thigh 30 days after Lower extremity computed tomography suggestive oval and thick implying or seroma. After using ultrasound scanning the mass, incision through previous surgical showed mass....
