REVIEW
Hui-Ming Chang, Tochukwu M Okwuosa, Tiziano Scarabelli, Rohit Moudgil, Edward T H Yeh
In this second part of a 2-part review, we will review cancer or cancer therapy-associated systemic and pulmonary hypertension, QT prolongation, arrhythmias, pericardial disease, and radiation-induced cardiotoxicity. This review is based on a MEDLINE search of published data, published clinical guidelines, and best practices in major cancer centers. Newly developed targeted therapy can exert off-target effects causing hypertension, thromboembolism, QT prolongation, and atrial fibrillation. Radiation therapy often accelerates atherosclerosis...

Effective biomaterial options for tissue repair and regeneration are limited. Current biologic meshes are derived from different tissue sources and are generally sold as decellularized tissues. This work evaluated two collagen based bioengineered constructs and a commercial product in a model of abdominal full thickness defect repair. To prepare the bioengineered construct, collagen type 1 from porcine skin was isolated using an acid solubilization method. After purification, the collagen was formed into collagen sheets that were physically bonded to form a mechanically robust construct that was subsequently laser micropatterned with pores as a means to promote tissue integration (collagen only construct)...

A 25 year old female with known neurofibromatosis type 1 with a large anterior mediastinal mass was investigated. F18-FDG PET-CT revealed a radiotracer avid anterior mediastinal mass with SUVmax of 4.3 and demonstrating a hypoactive center. The Iodine-123 MIBG SPECT-CT study performed subsequently did not demonstrate any uptake, thereby excluding for the most part the diagnoses of paraganglioma or neuroblastoma. At final pathology, a malignant peripheral nerve sheath tumour (MPNST) of the pericardium with areas of chondrosarcomatous and angiosarcomatous differentiation was diagnosed...

BACKGROUND: Pulmonary valve replacement is becoming the most frequent congenital heart surgery performed on adolescents and young adults. Numerous surgical options are available, including autologous pericardium, mechanical valves, allografts, and bioprosthetic valves. Each option has limitations with durability and freedom from reintervention for stenosis or insufficiency, particularly in the pediatric population. The purpose of this study was to analyze our uniquely designed, expanded polytetrafluoroethylene (ePTFE) valved conduit (VC) for right ventricular outflow tract reconstruction...

BACKGROUND: Epicardial fat tissue (EAT) is associated with coronary as well as aortic valve calcification. The study aim was to determine whether EAT thickness is different in patients with and without aortic valve stenosis (AVS). METHODS: A cohort of 200 consecutive patients with severe AVS and 200 matched patients without AVS were included retrospectively in the study. EAT thickness was quantified, using transthoracic echocardiography, as the space between the epicardial wall of the myocardium and the visceral layer of the pericardium...

The common causes of pericarditis and its course are benign in the majority of cases. Thus, further testing is usually not pursued and treatment for a presumptive viral etiology with nonsteroidal agents and steroids has been an accepted strategy. We present a patient with pericarditis who was unresponsive to first-line therapy and was subsequently found to have necrotizing granulomas of the pericardium with extensive adhesions and fungal elements seen on tissue biopsy. Serologic testing confirms active H. capsulatum infection, and he responded well to Itraconazole treatment...

A 63-year-old woman had persistent bloody pericardial effusion. Tuberculous pericarditis was initially suspected, but empirical antituberculosis therapy was futile. FDG PET/CT study revealed abnormal FDG activity in multiple parts of the pericardium, especially along with aorta and main pulmonary artery, and in the left atrium. However, there was no abnormal activity in other parts of the body. Histopathologic examination revealed primary pericardial angiosarcoma.

Asbestos refers to a group of minerals that appears naturally in the environment as bundles of fibers. The incidence rate of asbestos-related diseases has considerably increased as well as the amount of asbestos utilization in few countries. Malignant pleural mesothelioma (MPM) is a rare type of aggressive and life threatening neoplasm which arise from various serous surfaces: pleura, peritoneum, tunica vaginalis and pericardium. The first case of MPM was reported in 1947. MPM etiologically is associated to the exposure of asbestos fibers...

OBJECTIVE: To develop an animal model suitable for the study of acupoint sensitization in myocardial ischemia(MI) animals by observing changes of the mechanical withdrawal threshold (pain threshold, PT). METHODS: Twenty New Zea-land rabbits were randomly divided into control and model groups (n=10 in each group). The controllable MI model was set up by installing a balloon occluder at the left anterior descending branch of the left coronary artery. Air inflation of the balloon was given for 5 min/time, twice a day (4-hours' interval) for continuous 5 days (the first stage of MI), with one day's rest, then, another 5 days' air inflation was conducted again (2(nd) stage of MI)...

A 75-year-old woman experienced recurrent mitral regurgitation caused mainly by a shrunken and tethered posterior mitral leaflet with a dilated left ventricle. Posterior leaflet motion was severely restricted. We successfully resolved the tethering and restored valve coaptation and competence using posterior leaflet reconstruction, which is a modified method of posterior leaflet augmentation using autologous pericardium. This technique can recover the posterior leaflet function by improving tissue volume and tethering...

Mechanical heart-lung interactions are often overlooked in clinical settings. However, their impact on cardiac function can be quite significant. Mechanistic physiology-based models can provide invaluable insights into such cardiorespiratory interactions, which occur not only under external mechanical ventilatory support but in normal physiology as well. In this work, we focus on the cardiac component of a previously developed mathematical model of the human cardiopulmonary system, aiming to improve the model's response to the intrathoracic pressure variations that are associated with the respiratory cycle...

Tumours show an increased interstitial fluid pressure, which correlates with various pathophysiological features. Moreover, interstitial fluid pressure is a prognostic factor for cervical and lung cancer. However, there have been no reports on the usefulness of measuring interstitial fluid pressure in thymic epithelial tumours. Therefore, this study aimed to examine the relationship between interstitial fluid pressure and the clinicopathological characteristics of thymic epithelial tumours. Interstitial fluid pressure was prospectively measured at the centre of the tumour using a 1-Fr Mikro-Tip sensor catheter in 44 patients with thymic epithelial tumours, 40 with thymomas and 4 with thymic carcinomas...
