RESUMEN
Viral infections are a common cause of acute myocarditis. However, vaccines including influenza and smallpox have also been rarely implicated. Recently, the coronavirus disease 2019 (COVID-19) vaccines have been associated with acute myocarditis. We describe a case of acute myocarditis in a 19-year-old male 2 days after the initial dose of the COVID-19 mRNA-1273 vaccine. He presented with chest pain radiating to his left arm and bilateral shoulders. COVID, influenza, coxsackie, respiratory syncytial virus polymerase chain reaction (PCR) tests were negative. Electrocardiogram revealed diffuse ST-segment elevation. Initial Troponin was 15.7 ng/mL. A coronary angiogram revealed patent coronary arteries and no wall motion abnormality. A transthoracic echocardiogram showed diffuse hypokinesis with an ejection fraction of 49%. Cardiac magnetic resonance scan was aborted after 2 attempts due to severe claustrophobia. His chest pain resolved following initiation of aspirin, tylenol, colchicine, lisinopril, and metoprolol.

Secundum atrial septal defect (ASD) is the most common type of ASD. Symptoms including dyspnea on exertion usually manifest in the third and fourth decade of life. The transcatheter closure is the treatment of choice for secundum ASD. The transfemoral venous approach has been the mainstay. However, this approach can be challenging or impossible in patients with congenital absence or interruption of the inferior vena cava (IVC). The latter has been reported in patients with situs ambiguus and inversus. In this patient population, other forms of venous access such as the transjugular or transhepatic approach are used. We present a unique case of symptomatic secundum ASD in a patient who was incidentally found to have situs ambiguus with a left-sided intact IVC. An initial attempt at the ASD closure via the transfemoral approach was unsuccessful due to acute angulation. A repeat attempt was successful via the transhepatic approach with the guidance of real-time ultrasound, transesophageal echocardiogram, and the involvement of an interventional radiologist. The procedure was well tolerated without any complications. Repeat transthoracic echocardiogram with agitated saline the day after the procedure was negative for interatrial shunting.

Takotsubo cardiomyopathy, also known as stress cardiomyopathy, is known to have 4 variants: apical, midventricular, basal, and focal. Here, we report the 2nd case of reverse midvariant (midventricular) stress cardiomyopathy and the 1st case of reverse midvariant takotsubo cardiomyopathy with apical thrombus.
RESUMEN
This case describes a patient with pericardial effusion as a phenomenon of the drug-induced lupus erythematosus (DILE) syndrome due to hydralazine. The relevance of this case report lies in the fact that although hydralazine has been a known causative agent of DILE, its presentation may involve a negative anti-nuclear antibody (ANA) study. Pericardial effusion is a documented adverse effect as a result of hydralazine use. It is typically common to screen for DILE with the serum ANA test prior to proceeding to more costly and specific tests (i.e., anti-histone antibody). As per our literature review, this is the second case of hydralazine causing DILE with a negative ANA. As in our case, although the screening serum ANA is the initial next best step for suspicion of DILE by hydralazine, it is important to consider the diagnosis without ANA positivity.
RESUMEN
UNLABELLED: Spirometry has been reported to be under-utilized, and airflow obstruction may be under-diagnosed, in primary care practice. STUDY OBJECTIVES: The objective of this study was to determine the prevalence and severity of airflow obstruction in rural primary care settings and the degree to which it can be predicted by clinical characteristics. Spirometry was performed in patients 35 years and older who had smoked, presenting for any reason to one of eight rural primary care practices. Obstruction was defined as an FEV(1)/FVC<0.70. A total of 1046 subjects were recruited of whom 1034 had acceptable and reproducible spirometry. Airflow obstruction was detected in 17.4% (180 patients). Of those with obstruction, 77.2% (se 3.1%) had at least one respiratory symptom versus 62.4% (se 1.6%) without obstruction (P=0.0002). Only 44.9% (se 3.7%) of those with airflow obstruction had been previously diagnosed with obstructive lung disease. Of those with an FEV(1)<50% of predicted, 85% (se 5.6%) were breathless on exertion; however, only 63% (se 7.6%) were being treated with respiratory medications. We conclude that airflow obstruction is common in rural primary care practice and cannot be accurately predicted by symptoms. It is undiagnosed half of the time, and often not treated even when symptomatic.
