Abstract

Marijuana has become the most widely used illicit drug in the United States. Approximately 43.5 million Americans aged 12 or above have reported the use of marijuana in the last year. The use of cannabinoids and its relationship with cardiac effects are not well known. Many types of arrhythmias have been noted with the use of cannabis products with atrial fibrillation being the most common arrhythmia associated with the use of cannabis. We present a case of a 36-year-old male who presented with pounding chest pain, dyspnea, and diaphoresis following marijuana use. He was found to be in ventricular tachycardia which responded to amiodarone. Workup done was negative for any structural disease, and cardiac catheterization was negative for coronary artery disease. He was ultimately discharged on metoprolol. In this report, we focus on how marijuana can be associated with many arrhythmias including ventricular tachycardia with focus on mechanisms by which it can occur. We believe a detailed social history with screening for cannabis use can identify more cases of arrhythmias that can be potentially associated with marijuana use.

14. The Importance of Early Pericardiectomy in Mulibrey Nanism Syndrome, a Case Report.

Author

Sanchez, Andres Cordova, Vasigh, Mostafa, and Carhart, Robert

Abstract

Mulibrey (Muscle-Liver-Brain-Eye) Nanism syndrome is an extremely rare genetic disorder with multiorgan involvement. Constrictive pericarditis and diastolic dysfunction are the most common causes of mortality. We present a case of a patient with Mulibrey nanism syndrome who underwent pericardiectomy at 12 years old and was able to live 44 years more with relatively stable and asymptomatic diastolic congestive heart failure (CHF). This case highlights the importance of early recognition and treatment of constrictive pericarditis in these patients. [ABSTRACT FROM AUTHOR]

36. Anomalous origin of the left coronary artery from pulmonary artery misdiagnosed as postpartum cardiomyopathy.

Author

Nepal, Subash, Carhart, Robert L., Kadura, Suhayb, Barreto, Stephany, and Greca, Indrit

Abstract

A 30-year-old woman with a history of presumed postpartum cardiomyopathy presented to her primary care physician's office with crescendo angina and shortness of breath. She was found to be in supraventricular tachycardia, managed with the Valsalva maneuver, and was discharged home without any further workup. She again presented with exertional symptoms. Her electrocardiogram revealed abnormal T waves and her stress test was strongly positive. Cardiac catheterization revealed an absent left coronary ostium and a dilated right coronary artery, with large collaterals supplying the left coronary system; coronary computerized tomography revealed the anomalous origin of the left main coronary artery arising from the posterolateral aspect of the pulmonary artery, highly suggestive of the anomalous origin of the left coronary artery from pulmonary artery (ALCAPA) anomaly (Bland-White-Garland anomaly).

37. El síndrome cardiorenal en insuficiencia cardíaca: Un paradigma en evolución

Author

Kshatriya,Shilpa, Kozman,Hani, Siddiqui,Danish, Bhatta,Luna, Liu,Kan, Salah,Ali, Ford,Timothy, Michiel,Robert, Carhart,Robert, and Villarreal,Daniel

Abstract

Background: Heart failure constitutes a significant source of morbidity and mortality in the United States and its incidence and prevalence continue to grow, increasing its burden on the health care system. Renal dysfunction in patients with heart failure is common and has been associated with adverse clinical outcomes. This interaction, termed the cardiorenal syndrome, is a complex phenomenon characterized by a pathophysiological disequilibrium between the heart and the kidney, in which malfunction of one organ subsequently promotes the impairment of the other. Multiple neuro-humoral mechanisms are involved in this cardiorenal interaction, including the deficiency of and/or resistance to compensatory natriuretic peptides, leading to sodium retention, volume overload and organ remodeling. Management of patients with the cardiorenal syndrome can be challenging and should be individualized. Emerging therapies must address the function of both organs in order to secure better clinical outcomes. To this end, a multidisciplinary approach is recommended to achieve optimal results.
