Pulmonary Embolism in COVID-19 Treated with VA-ECLS and Catheter tPA.

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.

Use of ventricular assist device as bridge to simultaneous heart and kidney transplantation in patients with cardiac and renal failure.

Background: Ventricular assist device (VAD) implantation as a bridge to cardiac transplantation is an effective treatment option for end-stage heart failure. Renal dysfunction is not uncommon but is considered to be a poor prognostic factor. We present our experience with 6 patients who had combined heart and kidney transplantation (HKT) after VAD implantation for advanced cardiac and renal failure.

Successful combined heart-bilateral lung-kidney transplantation from a same donor to treat severe hypertrophic cardiomyopathy with secondary pulmonary hypertension and renal failure: case report and review of the literature.

This study describes the first reported case of a combined heart-lung-kidney transplantation. Our patient suffered from hypertrophic cardiomyopathy due to long-standing hypertension with Dana Point Classification Group 2 pulmonary hypertension from the underlying cardiac disease, along with renal failure necessitating renal replacement therapy. Twenty months after the transplant procedure, she has stable pulmonary and renal function, plus has resumed a normal daily life with improving exercise tolerance.

Left ventricular assist device as 'bridge to weight loss' prior to transplantation in obese patients with advanced heart failure.

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.

Intramyocardial injection of autologous cardiospheres or cardiosphere-derived cells preserves function and minimizes adverse ventricular remodeling in pigs with heart failure post-myocardial infarction.

Objectives: The purpose of this study was to test the safety and efficacy of direct injection of cardiosphere-derived cells (CDCs) and their 3-dimensional precursors, cardiospheres, for cellular cardiomyoplasty in a mini-pig model of heart failure after myocardial infarction.

Background: Intracoronary administration of CDCs has been demonstrated to reduce infarct size and improve hemodynamic indexes in the mini-pig model, but intramyocardial injection of CDCs or cardiospheres has not been assessed in large animals.

Methods: Autologous cardiospheres or CDCs grown from endomyocardial biopsies were injected through thoracotomy 4 weeks after anteroseptal myocardial infarction.
