Anomalous Right Coronary Artery Clinical Presentations and Considerations

Anomalous coronary artery presenting as syncope or acute decompensated heart failure complicated by cardiogenic shock is a relatively rare finding. Here, two unusual presentations are described in which an anomalous right coronary artery (RCA) with interarterial course was found following an initially negative workup. The first case describes a 71-year-old male with known non-ischemic cardiomyopathy presenting with acute decompensated heart failure and cardiogenic shock. The second case highlights a 44-year-old female presenting with intermittent angina and recurrent syncope of unknown etiology. These two cases suggest that the anatomy of coronary arteries and their anatomical variants may play a crucial role in the development of adverse cardiovascular outcomes. Utilizing cardiac computed tomography angiography with a lower threshold in patients presenting with cardiac signs, symptoms, and risk factors would lead to earlier detection of these anatomic anomalies and intervention either medically or surgically for potentially improved long-term outcomes.

Standardization of the Right Heart Catheterization and the Emerging Role of Advanced Hemodynamics in Heart Failure

The accurate assessment of hemodynamics is paramount to providing timely and efficacious care for patients presenting in cardiogenic shock. Recently, the regular use of the pulmonary artery catheter in cardiogenic shock has had a resurgence with emerging data indicating improved survival in the modern era. Optimal multidisciplinary management of advanced heart failure and cardiogenic shock relies on our ability to effectively communicate and understand the complete hemodynamic assessment. Standardization of data acquisition and a renewed focus on the physiological processes, and thresholds driving disease progression, including the coupling ratio and myocardial reserve, are needed to fully understand and interpret the hemodynamic assessment. This State-of-the-Art review discusses best practices in the cardiac catheterization laboratory as well as emerging data on the prognostic role of emerging advanced hemodynamic parameters.

A Case of Sinus of Valsalva Aneurysm Rupture Causing Cardiogenic Shock

A sinus of Valsalva aneurysm (SVA) is an abnormal dilation between the aortic valve annulus and sinotubular junction resulting from weakness in the elastic lamina. In the vast majority of cases, SVAs are asymptomatic and are incidentally detected on echocardiogram imaging. In some cases, they can rupture and lead to an intracardiac shunt. Sudden rupture of a high-flow aneurysm can lead to significant hemodynamic compromise and a high fatality rate if not diagnosed early and intervened upon. We present the case of a 68-year-old male who presented with symptoms of heart failure and later rapidly deteriorated due to a sudden spontaneous rupture of the SVA leading to cardiogenic shock. In our case, timely identification and intervention led to a good outcome for our patient. We also present echocardiogram images and videos to educate the readers further about diagnosing SVA. With this case report, we would like to help clinicians and researchers expand their understanding of the condition and treatment outcomes.

Cardiogenic Shock With Reverse Takotsubo Pattern Secondary to Pheochromocytoma: A Case Report

Pheochromocytoma is a rare catecholamine-secreting neuroendocrine tumor arising from chromaffin cells. Acute catecholamine-mediated cardiomyopathy secondary to pheochromocytoma is rare, but life-threatening. We report a case of a 50-year-old man who presented with chest pain with electrocardiography showing ST elevation in V2-4. He was transferred to cardiac catheterization laboratory for coronary angiography immediately. However, the results showed no evidence of coronary artery occlusions and the left ventriculography revealed hypokinesia of basal part with poor left ventricular ejection fraction. Further investigation confirmed pheochromocytoma-related reversible cardiomyopathy.
