Pericardial patch

UNLABELLED: Left ventricle pseudoaneurysm is a rare and life-threatening complication of myocardial infarction that is formed as a result of left ventricle free wall rupture contained by the overlying pericardium. Urgent surgical repair is crucial, and in most reports, left ventricle was reconstructed with a Dacron or bovine pericardial patch. We present a case of a 66-year-old female with left ventricle pseudoaneurysm which was successfully repaired with an extracellular matrix patch...

This case report highlights the successful application of a robotic-assisted surgical approach in managing Nutcracker syndrome. The patient, a 36-year-old female presented with severe symptoms and underwent robotic left renal vein transposition after failing conservative management. The procedure was performed through a minimally invasive approach utilizing the Da Vinci robotic system™ which offers enhanced visualization and precision. However, challenges arose during the renal vein anastomosis due to tension and poor flow through the transposition, requiring two revisions with a bovine pericardial patch...

The sensing of left ventricular (LV) activity is fundamental in the diagnosis and monitoring of cardiovascular health in high-risk patients after cardiac surgery to achieve better short- and long-term outcome. Conventional approaches rely on noninvasive measurements even if, in the latest years, invasive microelectromechanical systems (MEMS) sensors have emerged as a valuable approach for precise and continuous monitoring of cardiac activity. The main challenges in designing cardiac MEMS sensors are represented by miniaturization, biocompatibility, and long-term stability...

BACKGROUND: Alpha-gal syndrome is an allergic condition in which individuals develop an immune-mediated hypersensitivity response when consuming red meat and its derived products. Its diagnosis is important in individuals undergoing cardiac surgery, as patients frequently require large doses of unfractionated heparin or the insertion of surgical implants, both of which are porcine or bovine in origin. There are currently no guidelines for heparin administration in alpha-gal patients, with even less knowledge regarding the long-term clinical implications of these patients after receiving bioprosthetic valve replacements or other prostheses...

BACKGROUND: Cardiac herniation occurs when there is a residual pericardial defect post thoracic surgery and is recognised as a rare but fatal complication. It confers a high mortality and requires immediate surgical correction upon recognition. We present a case of cardiac herniation occurring post thymectomy and left upper lobectomy. CASE PRESENTATION: Initial presentation: A 48-year-old male, hypertensive smoker presented with progressive breathlessness and was found to have a left upper zone mass confirmed on CT biopsy as carcinoid of unclear origin...

Sinus venosus atrial septal defects (SVASDs), concurrent with partial anomalous pulmonary venous connections (PAPVCs), are a rare congenital heart disease in dogs. Surgical correction is essential when clinical signs or significant hemodynamic changes are present. We aimed to report on the successful surgical correction of an SVASD with PAPVCs, using a computed tomography (CT)-based customized 3D cardiac model. A 10-month-old male poodle was referred for corrective surgery for an ASD. Echocardiography confirmed a hemodynamically significant left-to-right shunting flow through an interatrial septal defect and severe right-sided heart volume overload...

OBJECTIVES: Repair of the bicuspid aortic valve has evolved in the past 25 years. The aim of this study was to review and analyze the long-term durability of isolated BAV repair with particular focus on commissural orientation (CO). METHODS: All patients who underwent bicuspid aortic valve repair for severe aortic regurgitation between 10/1998 and 12/2022 were included. The study group consists of all patients operated after 2009 ie, since CO modification...

OBJECTIVE: The use of biological grafts provides acceptable mid- and long-term results in native or prosthetic vascular infections. Several reports describe the successful use of bovine pericardium in case of vascular infections, mainly as a large patch to be sutured as a tubular graft. Recently, a novel prefabricated bovine pericardium graft (Biointegral Surgical No-React® Inc, Mississauga, ON, Canada) has been introduced in clinical practice with promising results. In this study, we report our preliminary experience utilizing Biointegral Surgical graft in case of native and or prosthetic aorto-iliac and infra-inguinal infection...

INTRODUCTION: Primary vascular leiomyosarcomas are incredibly rare and have a poor prognosis. The purpose of this study was to analyze the surgical outcomes of patients with primary inferior vena cava (IVC) leiomyosarcoma. METHODS: We performed a retrospective review of IVC leiomyosarcoma resections performed at a single tertiary care hospital from 2014 to 2023. A total of 13 cases were analyzed, including 10 women and 3 men. The presenting symptoms, tumor characteristics, operative management, postoperative complications, and survival rates were assessed for each patient...

BACKGROUND: Primary cardiac angiosarcomas are very rare and present aggressively with high rates of metastasis. Given the poor prognosis, particularly once disease has spread, early diagnosis and multidisciplinary treatment is essential. CASE PRESENTATION: We present the case of a 46-year-old male who presented with chest pain, intermittent fevers, and dyspnea. Workup with computed tomography scan and transesophageal echocardiography demonstrated a right atrial pseudoaneurysm...

We present a case of an unvaccinated, 43-year-old African American female patient with COVID-19 infection and clinical evidence of a left hemispheric stroke. A non-occlusive thrombus with a radiographic target lesion was identified on computed tomography angiography (CTA). A multi-disciplinary discussion regarding concern for embolization was provided due to its unstable nature, as well as evidence of recent stroke. Given her acute COVID-19 infection, symptomatology, and radiographic findings, it was concluded that the etiology of her stroke appeared most consistent with a hypercoagulable-related embolism rather than an atheroembolic event...

INTRODUCTION: Supravalvular aortic stenosis (SVAS) is an uncommon congenital abnormality that presents with intimal thickening of the aortic media at the sinotubular junction. Given the congenital nature of the disease, patients usually become symptomatic in childhood. PRESENTATION OF CASE: A 48-year-old man developed symptomatic SVAS in middle age. A patch aortoplasty with a bovine pericardial patch was performed. His postoperative course was uneventful, and echocardiography revealed a significant decrease in peak velocity and pressure gradient...

Ventricular septal defects (VSDs) are a prevalent congenital heart anomaly demanding safe and lasting interventions. This paper explores the application of Invengenx® bovine pericardial patch (Tisgenx, Irvine, California), a promising biomaterial, in VSD repair. We present two case studies: a seven-month-old infant and a three-year-old child undergoing VSD closure using autologous and bovine pericardial patches, respectively. Both patients tolerated the procedures well, experiencing no intra-operative complications and demonstrating excellent postoperative recovery...

The replacement of the superior vena cava and thoracic outlet vessels for thoracic malignancies often becomes necessary for radical oncological surgery. The pulmonary artery can be directly infiltrated by the tumor or affected by metastatic hilar lymph nodes. In some cases, it must be resected and reconstructed to achieve oncological radicality and/or avoid pneumonectomy. This study reflects a single-surgeon, retrospective experience spanning 6 years (2017-2023). We reviewed data from patients undergoing early anticoagulant therapy after superior vena cava or thoracic outlet vessels bypass and from patients undergoing early antiaggregation therapy following pulmonary artery reconstruction or resection...

BACKGROUND: Takotsubo cardiomyopathy (TCM) is a temporary and reversible systolic abnormality of the left ventricular apical area resembling a myocardial infarction. Cardiac rupture due to TCM is a rare but fatal complication. Without cardiac surgery, 94% of patients with left ventricular free wall rupture (LVFWR) due to TCM die. Furthermore, successful surgical cases are rare. We report herein the successful treatment of multiple LVFWRs due to TCM using a sutureless repair. CASE PRESENTATION: An 80-year-old man quarreled with his daughter and had a sudden onset of chest pain...

A 46-year-old woman presented for a routine echocardiogram, which revealed a giant atrial septal aneurysm (ASA) with an atrial septal defect (ASD). We surgically excised the ASA and closed the ASD with a pericardial patch. ASA, although rare, poses embolic risks, thus necessitating closure when associated with shunts. Optimal stroke prevention remains uncertain.

Fractures and dislocations of the sternoclavicular joint (SCJ) are uncommon, accounting for <5% of all shoulder girdle injuries. They are relatively more common in the pediatric population than in the adult population and can often present concurrently as a posteriorly displaced medial clavicular dislocation with a fracture through the unfused physis. It is especially important to recognize this injury, because its management and potential sequelae are very different from those for fractures of the clavicle shaft...

Unroofed coronary sinus (UCS) represents a rare subtype of atrial septal defect (ASD), an adult congenital heart disease characterized by communication between the systemic and pulmonary circulations at the atrial level. This case report presents the unique occurrence of a large, unrepaired ASD secundum and an incidentally identified UCS type II in a 25-year-old female during a cardiac murmur assessment. The diagnosis of ASD secundum was initially made using transthoracic echocardiography (TTE) and was later confirmed with a transesophageal echocardiogram...

BACKGROUND: Management of large central airway defects are often complex. Children who present with these defects have multiple co-morbidities or have had previous surgeries. Surgical options include various tissue cover for these defects without longer term benefits. Vascularized autologous pericardial patch offers a better solution to these defects by providing vascularity and potential for remodelling in future. METHODS: 41 children (M:F of 24:17) were operated for large trachea-bronchial defects between January 2015 and August 2022...

INTRODUCTION: Pericardial effusion is common in the setting of rheumatoid arthritis (RA); however, it is rarely its first manifestation. CASE DESCRIPTION: An 82-year-old male presented with abdominal pain, vomiting and fever. Blood analysis revealed elevated systemic inflammatory markers, and an abdominal computed tomography scan revealed non-specific alveolar condensation of the right pulmonary base and pericardial effusion subsequently quantified as medium size by transthoracic echocardiography...
