226. Case Report: Fall from Grace – A Case of Pulmonary Embolism – Massachusetts General Hospital

Cardionerds: A Cardiology Podcast

CardioNerds (Amit and Dan) join join Dr. Andrew Dicks (Vascular medicine physician at Prisma Health, former fellow at Mass General Vascular) and Dr. Prateek Sharma (Vascular interventional & medicine fellow at MGH) for an ice-cold drinks at the Esplanade in Boston, MA to discuss a case about a patient who developed a pulmonary embolism and masterfully discuss the diagnosis and management of of pulmonary emboli. Dr. Ido Weinberg (Director, Vascular Medicine Fellowship at MGH) provides the ECPR for this episode. Case Abstract: A 59-year-old Spanish-speaking man with no significant past medical history presents after falling 15-20 feet from a ladder and landing on his back. He was found to have an L1 fracture and left radial fracture and underwent T12-L2 fusion with neurosurgery on hospital day 1 and ORIF of left radial fracture with orthopedic surgery on hospital day 2. On hospital day 5, he develops acute onset tachycardia with HR in the 130s bpm with new O2 requirement associated with mild shortness of breath at rest without any chest discomfort. His labs were notable for an elevated troponin and proBNP. He underwent CTPA which demonstrated acute bilateral occlusive pulmonary emboli (PE) extending in the right and left main pulmonary arteries. TTE demonstrated right ventricle dilation. The patient was started on a heparin infusion and a PE response team (PERT) meeting was held to discuss treatment options. Given recent surgery, use of thrombolytic therapy was felt to be too risky and thus he was taken for percutaneous thrombectomy in the cath lab. PA pressure prior to intervention was 51/21 mmHg. The patient underwent suction thromboembelectomy with the Flow Triever device with extraction of thrombus and improvement in PA pressure to 19/11 mmHg. He was treated with anticoagulation thereafter and discharged home two days after the procedure.

Case Media Acute bilateral occlusive and nonocclusive pulmonary emboli extending from the right and left main pulmonary arteries to the lobar and segmental arteries of all the lobes. Moderate right heart strain including the right atrium and the right ventricle. RV/LV ratio > 1.0. Right ventricular cavity is dilated (RV size at the base measures to 45mm). Right ventricular systolic function is moderately decreased. Right ventricular free wall is hypokinetic with sparing of the right ventricular apex consistent with acute right ventricular strain Pulmonary angiography demonstrated extensive proximal bilateral PEs Caption: Post-procedure TTE demonstrated resolution of RV strain with normalization of RV size and function. Episode Schematics & Teaching Pearls While there are markers to suggest PE, such as ECG findings or evidence of RV dilatation, a PE cannot be confirmed without imaging.Elevation of cardiac biomarkers and evidence of RV dysfunction are used to risk stratify PE, not the degree of thrombus burden or locale of thrombus.Enoxaparin is the preferred anticoagulant to initiate at time of PE diagnosis if comorbidities allow.Optimal treatment of intermediate risk PE remains uncertain as there is little data about long-term outcomes. Aggressive treatment should be used judiciously and chosen on a case-by-case basis.PE response teams (PERT) allow for multidisciplinary expert opinion in the face of scarce evidence to determine what is felt to be the best management strategy. Notes 1. What is a PERT team and why is it helpful? We have several tools and approaches for the management of PE. There are also many subspecialities involved in the care of patients with PE, including vascular medicine,
