Background: Novel coronavirus 2019 (COVID-19) has been the focus of the medical world since being declared a pandemic in March 2020. While the pathogenesis and heterogeneity of COVID-19 manifestations is still not fully understood, viral evasion of cellular immune responses and inflammatory dysregulation are believed to play essential roles in disease progression and severity.
Case Presentation: We present the first case of a patient with COVID-19 with massive pulmonary embolism treated successfully with systemic thrombolysis, VA-ECLS, and bail out catheter directed thrombolysis.
Background: Obesity is a risk factor for heart failure (HF) and associated with poor outcomes after cardiac transplantation. We assessed change in total body weight, morbidity and mortality in obese heart failure patients after implantation of a left ventricular assist device (LVAD) compared to medical management.
Material/methods: Nineteen patients (9 females, age 51.
Background: Gastroesophageal reflux and aspiration contribute to the development of bronchiolitis obliterans and accelerate graft deterioration after lung transplantation (LTx). We evaluated LTx candidates for esophageal motor abnormalities and gastroesophageal reflux.
Methods: Consecutive patients evaluated for LTx underwent 24-hour pH monitoring using a dual-channel pH probe and high-resolution esophageal manometry.
Deciding who should receive maximal technological treatment options and who should not represents an ethical, moral, psychological and medico-legal challenge for health care providers. Especially in patients with chronic heart failure, the ethical and medico-legal issues associated with providing maximal possible care or withholding the same are coming to the forefront. Procedures, such as cardiac transplantation, have strict criteria for adequate candidacy.

We present the case of a man with heparin-induced thrombocytopenia (HIT) and acute idiopathic decompensated cardiomyopathy who underwent successful heart transplantation with the use of bivalirudin as anticoagulant.

Cardiac computed tomographic angiography (CCTA) including volume rendered images predicted the appearance of the fistula entrance and defined spatial relationships facilitating the surgical approach. CCTA ability to define the coronary anatomy obviated the need for invasive coronary angiography.

Microwave energy allows thoracoscopic beating-heart ablation for the treatment of atrial fibrillation. However, there is a paucity of data on the histologic effects of microwave energy on the beating human heart. This study aims to histopathologically characterize microwave lesions on the beating human atrium.

International Society for Heart and Lung Transplant (ISHLT) guidelines suggest an upper age limit of 60 for BLT, despite limited data regarding outcomes with BLT in patients over 60. We hypothesize that BLT offers comparable, if not superior, clinical outcomes to SLT in all patients independent of recipient age.

Treatment of this condition with heart transplantation, however, requires that the primary malignancy be deemed "cured." We present the case of a 55- year-old woman who had doxorubicin-induced cardiomyopathy and non-Hodgkin's lymphoma.

Design: Prospective clinical study.
Setting: Academic medical center.
Splenic abscess is a rare clinical entity that is most commonly associated with infective endocarditis. Valve replacement in the setting of an unaddressed splenic abscess is associated with a high incidence of prosthetic valve infection and death. We describe 2 patients with infective endocarditis and splenic abscess treated by laparoscopic splenectomy followed by valve replacement.
