Percutaneous Mitral Valve Repair in Cardiac Amyloidosis and Severe Mitral Regurgitation.

Amyloidosis is an infiltrative disease with severe impact on the cardiac anatomy resulting in structural changes1. Mitral valve insult from the infiltrative process, although rare, has been known to cause severe mitral regurgitation4. Due to underlying comorbidities these patients may not be surgical candidates.17,18,19,20 The role of percutaneous mitral valve repair in cardiac amyloidosis has been described in a few prior cases.4,15 We review the epidemiology, diagnosis, and treatment of cardiac amyloidosis. We also highlight prior cases described in the literature of cardiac amyloidosis and severe mitral regurgitation, while discussing the role of percutaneous mitral valve repair in these patients.

Clinical Characteristics and Outcomes in Immune Checkpoint Inhibitor Therapy-Associated Myocarditis.

Immune checkpoint inhibitor (ICI) therapy has played an important role in the treatment of several groups of cancers. Although a life prolonging treatment, many side effects have been shown with ICI therapy. This study looked at individual level clinical characteristics and outcomes with ICI therapy in patients who developed ICI-related myocarditis. A comprehensive review of the National Library of Medicine PubMed database was performed. Inclusion criteria were all studies that were composed of case reports and case series of individual patients undergoing ICI therapy that developed myocarditis. To appreciate individual patient level data, observational studies, clinical trials, systematic reviews, and meta-analyses were excluded. Our search yielded 333 results with 71 cases reviewed of ICI therapy-related myocarditis. The findings included an average age of 68 years, higher incidence in men, and pretreatment cardiac history of hypertension. Melanoma was the most prevalent malignancy with nivolumab being the most used ICI therapy. Heart failure was the most prevalent adverse event that was co-prevalent with myocarditis. Corticosteroid therapy alone was the most utilized therapy to treat ICI-related myocarditis. Mortality was seen in nearly half of the patient population. Our study reviewed the preexisting literature of prior reported myocarditis secondary to ICI therapy. Periodic surveillance should be performed by the cardio-oncologist and internist. Due to the expanding role of ICI therapy in treating a variety of cancer patients, appreciation of its impact on the development of myocarditis is needed.

Immune Thrombocytopenic Purpura in a Patient With SARS-CoV-2 and Epstein-Barr Virus.

A 35-year-old female was admitted to the hospital for menorrhagia and fatigue. Initial labs revealed that the patient had severe thrombocytopenia and also tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main objective in this case is to describe the investigation that eventually led to a diagnosis of idiopathic thrombocytopenic purpura (ITP) in the setting of a SARS-CoV-2 coronavirus disease 2019 (COVID-19) infection and co-infection with Epstein-Barr virus (EBV). The majority of ITP cases are idiopathic and most are diagnosed and managed without hospital admission. Admission and careful management were warranted in this particular case. Interestingly, however, the patient did not have any respiratory complications associated with COVID-19. She was given 1 unit of platelets and subsequently received intravenous corticosteroids. Platelet counts improved and the patient was discharged with a course of oral prednisone. This case highlights the importance of understanding the differences between primary and secondary ITP.

Aortic Stenosis Complicated by Gastrointestinal Arteriovenous Malformations: It is not Always Heyde Syndrome.

Aortic stenosis (AS) and arteriovenous malformations (AVM) are a common coexisting pathology in the elderly. When both pathologies are combined, Heyde syndrome is a differential that is widely explored among clinicians. Unfortunately, this may not always be the case. We present a case of an 82-year-old female admitted for acute gastrointestinal (GI) bleeding with a history of AVMs and AS, as well as, an algorithm in diagnosing elderly patients with both pathologies.

Oxaliplatin-induced Pulmonary Toxicity: A Rare but Serious Complication.

The FOLFOX regimen (oxaliplatin, leucovorin, and 5-fluorouracil) is FDA approved for use in patients with colorectal cancer and other gastrointestinal malignancies. The initial phase III randomized controlled trials that led to FDA approval of oxaliplatin with leucovorin and 5-fluorouracil showed a less than 1% incidence of pulmonary fibrosis and grade IV pulmonary toxicities. Here we describe two cases of pulmonary toxicity in patients with metastatic colorectal cancer treated with FOLFOX and briefly review the literature regarding oxaliplatin-induced pulmonary toxicity.

Neoadjuvant Radiation with Concurrent 5-FU Resulting in Complete Pathologic Response in Stage IIIB Squamous Cell Carcinoma of the Urethra.

Squamous cell carcinoma (SCC) of the urethra is a rare malignancy, comprising less than 1% of all malignancies. The annual age-adjusted incidence of urethral SCC is 4.3 per million in men and 1.5 per million in women. Due to the rarity of the disease, there are a limited number of prospective randomized controlled trials to evaluate the optimal management of locally advanced urethral SCC. Here, we present the case of a 47-year-old man with stage IIIB urethral squamous cell cancer that showed complete clinical and pathologic response to neoadjuvant chemoradiation with only 5-flurouracil after incomplete response to traditional chemotherapy with paclitaxel, ifosfamide, and cisplatin (TIP).
