Presentation
We present the case of an 80-year-old female with a floating right heart thrombus in conjunction with an acute massive pulmonary embolism, who presented in cardiogenic shock. We successfully carried out surgical embolectomy. [ncbi.nlm.nih.gov]
To the authors’ knowledge, the present report is the first to describe a case involving acute PE presenting as hemodynamically unstable AVNRT requiring cardioversion. [pulsus.com]
Respiratoric
- Dyspnea
Treatment resulted in immediate angiographic improvement and initial relief of PE symptoms (improvement in dyspnea and oxygen saturation) in 16 of 17 patients. [ncbi.nlm.nih.gov]
A73-year-old man was admitted to the intensive care unit because of sudden onset of dyspnea followed by syncope. [circ.ahajournals.org]
Clinical findings Nonspecific; index of suspicion should be high in patients with dyspnea, tachypnea, or chest pain and risk factors for pulmonary embolism. [medical-dictionary.thefreedictionary.com]
Case Resolution Case 1 This patient presents with acute chest pain/dyspnea and is found to have a pulmonary embolism. Because of persistent hypotension, she is classified as a massive PE. [emdocs.net]
- Tachypnea

The physical examination can reveal hypotension, tachycardia, tachypnea, or cyanosis. Signs of acute RV dysfunction include distended neck veins, a parasternal heave, an accentuated P2, and a tricuspid regurgitation murmur. [phaonlineuniv.org]
The most common signs of PE are tachypnea and tachycardia. Many patients appear anxious. Lung exam is often normal but may reveal rales or decreased breath sounds. [uscjournal.com]
Clinical signs consistent with major PE include transient syncope, cyanosis, elevated jugular venous pressure, tachypnea, unilateral restriction of chest wall movement, fever, and signs of RV dysfunction ( Table 2). [intechopen.com]
- Rales
Lung auscultation revealed minimal diffuse rales bilaterally. Radial and pedal pulses were intact. Right lower extremity had 1+ pitting edema and Homans' sign was positive. Upper and lower extremities were warm to touch, and there was no cyanosis. [omcr.oxfordjournals.org]
Lung exam is often normal but may reveal rales or decreased breath sounds. An extremity exam may reveal a palpable cord, unilateral or asymmetric edema, tenderness, warmth, erythema, or superficial venous dilation. [uscjournal.com]

- Pleuritic Pain
The classic presentation for PE with pleuritic pain, dyspnea and tachycardia is likely caused by a large fragmented embolism causing both large and small PEs. [en.wikipedia.org]
The most common presenting symptom is dyspnea, followed by symptoms of pulmonary infarction, including pleuritic pain, cough, and, less commonly, hemoptysis. Symptoms of deep vein thrombosis (DVT), including leg swelling or pain, may be present. [uscjournal.com]

Workup
(See Workup.) Immediate full anticoagulation is mandatory for all patients suspected to have DVT or pulmonary embolism. Diagnostic investigations should not delay empirical anticoagulant therapy. (See Treatment.) [emedicine.medscape.com]
Troponins are commonly part of the normal workup for chest pain and shortness of breath. [journalofclinicaltrialresults.com]
While most patients with suspected PE will have computed tomography angiography of the chest, on occasion concerns for acute renal injury will prompt workup with ventilation-perfusion scans. [intechopen.com]
Current established regimen for management of pulmonary embolism Anticoagulation When acute PE is considered likely, anticoagulation with heparin should be begun while pursuing the diagnostic workup [61]. [ncbi.nlm.nih.gov]

Sinus tachycardia, supraventricular tachyar-rhythmias, the S1Q3T3 pattern, new complete or incomplete right bundle branch block, and p pulmonale are some of the ECG patterns described in association with pulmonary embolism [9, 12]. [ncbi.nlm.nih.gov]
Other ECG Findings
- Electrocardiogram Change
Patients were monitored for heart rate, blood pressure, rhythm, symptoms, electrocardiogram changes, and rate of perceived exertion (on a 1 to 10 scale, with 10 indicating maximum exertion) at rest and at every stage of the exercise protocol. [kjim.org]
Treatment
There were two deaths, both within 24 hours of treatment and secondary to PE. One death occurred in a patient who had only minimal thrombus removal after treatment with the RTC and no thrombolysis. [ncbi.nlm.nih.gov]
Prognosis
Abstract Patients who experience hemodynamic collapse after acute massive pulmonary embolism have a poor prognosis. Herein, we report our results with 8 patients and discuss a surgical strategy that can improve perioperative survival. [ncbi.nlm.nih.gov]
or —Elevation of troponin T (>0.1 ng/mL) Fibrinolysis is reasonable for pts with massive PE and acceptable risk of bleeding complications (IIa/B) Fibrinolysis may be considered for pts with submassive PE judged to have clinical evidence of adverse prognosis [emcrit.org]

Those with “submassive” PE, characterized by only mild RV enlargement/hypokinesis and with no residual leg DVT, likely have a much better prognosis. [phaonlineuniv.org]
Etiology
Ten patients died because of hypoxemia and hypotension prior to initiation of cardiopulmonary bypass, and seven died of myocardial depression of multiple etiologies. [ncbi.nlm.nih.gov]

Secondly, a more extensive review is given about the appearance, the etiology and pathogenesis, the pathology, radiology and clinical features of the acute respiratory insufficiency produced by intrapulmonary venous-to-arterial shunts. [tandfonline.com]
In patients with significant cardiac disease, pulmonary symptoms are often ascribed to cardiac etiology, but rarely concomitant PE may be discovered [ 62 ], in which case surgical pulmonary embolectomy may be combined with the operation to treat the primary [intechopen.com]

Prevention
Preoperative angiography was performed in 57% of the cases, and in another ten patients suspected of having pulmonary emboli, angiography prevented unnecessary thoracotomy. Despite their moribund condition, 43% of the embolectomy patients lived. [ncbi.nlm.nih.gov]
Prevention Preventing clots in the deep veins in your legs (deep vein thrombosis) will help prevent pulmonary embolism. [mayoclinic.org]
How can a pulmonary embolism be prevented? This involves preventing a DVT. See separate leaflet called Preventing DVT When You Travel. [patient.info]
In the United States, for instance, 80% of patients will be treated under a preventive regime within the next five years, compared to only 30% today. [debeurs.nl]
