Left Ventricular Dysfunction

A 29-year-old patient, with a recent history of mild COVID 19 infection, consulted for a 5-day history of fever, associated with abdominal pain, arthralgia and myalgia. Hypotensive on admission (80/50 mmHg), with HR 100 bpm and echocardiography performed with a convex transducer: LVEF 12%, with global hypokinesia and dilated cavities. The diagnosis of post-COVID myocarditis is made.

This patient presented with worsening “GERD” symptoms over the past 8 days, found to have markedly elevated troponin and anterior STEMI on ECG.

The parasternal long axis view revealed a ventricular septal defect. Using color doppler, flow can be visualized as the color jet passing across the septum.

A 50 year old male with community acquired pneumonia presented to the ED with worsening symptoms, abnormal EKG, and elevated troponin without an obstructing lesion on cath. Bedside echo revealed akinesia of the entire mid and apical left ventricle indicative of Takotsubo cardiomyopathy on apical 2 chamber (left) and apical 4 chamber (right) views.

52-yo-male with PMH methamphetamine use presented with 1 month history of increasing DOE, orthopnea, and episodic atypical sharp chest pain. EKG revealed LVH with inferolateral T-wave inversions; troponin was indeterminate (making ACS less likely). POCUS demonstrated extremely reduced LVEF leading to a diagnosis of new systolic heart failure. Subsequent formal TTE demonstrated LVEF 10%; left heart cath revealed nonobstructive CAD. Final diagnosis of methamphetamine induced cardiomyopathy was made.

A 60-year-old female presented with palpitations; found to have atrial fibrillation. Parasternal long POCUS was notable for both an enlarged LA as well as depressed LV systolic function. These concurrent diagnoses enabled initiation of proper rate-control while also being mindful to not worsen HF exacerbation (avoiding b-blockade). The combination of A.fib as well as LV dysfunction also made this patient particularly high risk of thromboembolic events; she was therefore also initiated on therapeutic anticoagulation.

A patient presented with out-of-hospital cardiac arrest. POCUS was used to confirm presence of cardiac standstill. Note the absence of movement of the left ventricular free wall.

A 50-year-old male presented to the ED with signs/symptoms of acute ischemic cerebrovascular accident (hemiplegia and dyslalia). Head CT confirmed the presence of a subacute ischemic event. Bedside POCUS (apical four chamber view) revealed severe LV global hypokinesis and the presence of an apical thrombus; the likely etiology of his cardioembolic event.

Pictured is an apical 2 chamber view from a 60-year-old female who presented to our ED with acute hypoxic respiratory failure. Note the presence of LVH and LV systolic dysfunction. PLAX view additionally confirmed the presence of critical aortic stenosis; lung views were notable for >3 B-lines per frame; all consistent with her clinical picture of acute cariogenic pulmonary edema.

The Case:

A 45 year old with history of diabetes presented with chest pain and shortness of breath. Cardiac #POCUS demonstrates LV apical ballooning with basal hypercontraction consistent with Takotsubo. This was confirmed with normal coronaries on cardiac cath.

A 52-year-old female presented to the ED with acute onset of upper abdominal pain and cough productive of frothy, pink sputum. She was ill-appearing, tachypneic, tachycardic, and hypotensive. POCUS revealed severe hypokinesis of the LV basal wall with a hyperdynamic apex, and diffuse B lines in both hemithoraces. She was in cardiogenic shock secondary to basal (aka reverse) Takotsubo cardiomyopathy (TCM). This variant accounts for only ~3% of TCM cases. Interestingly, 6 months ago she suffered from the typical (apical) variant. The recurrence rate in the 1st year is ~1.5%, but having a different variant is even more rare! (The U/S clip has been slowed down to make it easier to visualize the RMWAs.)

Elderly F w/ PMHx HTN and metastatic cancer arrived as a notification for sudden, witnessed syncope. EMS found PEA on EKG, intubated her, delivered 1 shock by AED, and obtained ROSC after 2 rounds of Epi. During transport she became pulseless again, and a 2nd ROSC was achieved w/ Epi in ED. During pulse check echo was used to evaluate for organized cardiac activity. Echo revealed a mild pericardial effusion w/o tamponade in PLAX, normal cardiac architecture, and absence of organized atrial and ventricular contractions. Disorganized ventricular movement correlated w/ VFib on the monitor.
Rescuer pulse palpation is only 78% accurate according to Tibballs and Russell (2008). POCUS in cardiac arrest allows for the assessment of organized cardiac activity w/o a palpable pulse, and for further evaluation of the Hs and Ts in PEA arrest. Given the need to maintain coronary perfusion w/ high quality CPR, the PLAX view is typically the fastest, provides actionable information and can be performed during standard ACLS pulse checks.

Bedside Echo of patient with Takotsubo's Cardiomyopathy and a regional tamponade where the effusion is not visible in the parasternal long.

Dr. Evan Baines - Augusta, Georgia

A 50 years old, complaining of dyspnoea and chest pain. She had no prior history of cardiopulmonary disease. Initial ultrasound of the lung fields demonstrated plenty of B-lines bilaterally.

An apical cardiac view (view is flipped with LV on left side of screen) demonstrates hypokinesis & aneurysmal dilation of the apex consistent with Takotsubo's cardiomyopathy. The patient's heart failure was managed supportively and a catheterization was performed during hospitalization that showed normal coronary artery stenosis. She had a full recovery

One way to evaluate cardiac function is to measure the distance from the anterior leaflet of the mitral valve to the septum during diastole. This is known as end point septal separation (EPSS).

An EPSS < 7 mm is considered normal, while EPSS > 10 mm suggests decreased cardiac function.

This measurement should be obtained in a parasternal long axis view, using M-mode with the cursor placed through the tip of the mitral valve.

60s M with no known PMH presented to the ED with 3 weeks of progressive dyspnea and bilateral leg edema. POCUS was performed to assess his cardiac function. This clip demonstrates the parasternal long axis and apical 4-chamber views, showing markedly globally reduced LV function, and the endocardium is well seen here. The patient was admitted for further evaluation of his newly diagnosed cardiomyopathy, and formal echocardiography revealed a subtle apical LV thrombus which is not well seen on this POCUS.

24-yo-male who had been diagnosed with granulomatosis with polyangiitis 10 months prior presented with DOE and progressive bilateral lower extremity edema. Clinical suspicion of cardiac dysfunction was confirmed by POCUS; seen here is the apical 5-chamber view, nearly unable to fit on screen due to severity of bi-ventricular dilation and impaired systolic function.

50 y/o M PMH methamphetamine abuse presents in respiratory failure with cool, mottled skin and poor capillary refill. Patient was tachycardic, hypothermic with multiple signs of end organ dysfunction. POCUS quickly narrowed the differential by demonstrating clear, severe, reduced ejection fraction by visual estimation and a plethoric IVC without respiratory variation. Patient was ultimately started on dobutamine and transferred to the MICU for treatment of cardiogenic shock.

Out of hospital arrest brought in by EMS. CPR had been ongoing for 20 minutes without ROSC. Parasternal short axis view at mid papillary level shows complete LV standstill once resuscitation was stopped, confirming the clinical diagnosis.

60s M presented with L arm and axillary pain for 1 day. EKG with subtle ST elevation in II/III and depression in I, aVL without meeting STEMI criteria. HsTrop elevated to about 25,000. POCUS demonstrated hypokinesis of the inferior and lateral walls. Cardiology felt most c/w NSTEMI and missed inferior MI. TTE confirmed regional wall motion abnormalities, and after medical optimization, pt went to cath lab and had RCA occlusion diagnosed and stented.
