Case Report: Wellens Syndrome In 28-Year-Old With Pleuritic Chest Pain, Tucker A. Ledo May 2024

Case Report: Wellens Syndrome In 28-Year-Old With Pleuritic Chest Pain, Tucker A. Ledo

Rowan-Virtua Research Day

We report a case of a 28-year-old male with months of diffuse, pleuritic, intermittent, non-exertional chest pain. He had an elevated troponin and ECG showing Wellens’ syndrome and was found to have 80% LAD coronary artery occlusion and 100% apical occlusion. Identification and proper management of Wellens’ syndrome relies on being familiar with its ECG patterns. Other information such as age, cardiac risk factors, chest pain with exertion and at rest, and elevated troponin, are all helpful supplemental information, but as demonstrated in the following case report, presentations may vary or even cause as distractors to the diagnosis.

Atypical Case Of Recurrent Saddle Pulmonary Embolism With Associated Chronic Hypoxia, Karl Schlicht May 2024

Atypical Case Of Recurrent Saddle Pulmonary Embolism With Associated Chronic Hypoxia, Karl Schlicht

Rowan-Virtua Research Day

A saddle pulmonary Embolism (PE) represents a blood clot within the pulmonary artery vasculature that lodges itself between both the left and right pulmonary artery. They can be described as being massive or sub-massive. Massive PE’s cause large clot burden that puts the patient risk for sudden hemodynamic collapse, while sub-massive saddle PE’s typically do not cause hemodynamic collapse nor significant cardiac effects, such as right heart dysfunction. As clinicians, we need to be vigilant about whether a patient is placed into that criteria of sub-massive or massive and act quickly to start management that could be lifesaving.
