Abimbola O Faloye, Raphael Y Gershon
Traumatic ventral septal defect may be sustained after either blunt force or penetrating trauma to the chest. Severity ranges from asymptomatic to acute decompensated heart failure. Our patient suffered a stab wound to the chest and was initially taken to the operating room for repair of a lacerated right ventricle. Subsequent postoperative hemodynamic deterioration prompted a bedside transthoracic echocardiogram, which failed to identify causal factors. A transesophageal echocardiogram performed immediately after ventral septal defect was demonstrated...

Carlo Vignati, Gaia Cattadori
Cardiac output is a key parameter in the assessment of cardiac function, and its measurement is fundamental to the diagnosis, treatment, and prognostic evaluation of all heart diseases. Until recently, cardiac output determination during exercise had been only possible through invasive methods, which were not practical in the clinical setting. Since oxygen uptake (V.O2) is cardiac output times arteriovenous content difference [C(a-v)O2)], evaluation of cardiac output is usually included its measurement. Because of the difficulty of directly measuring peak exercise cardiac output, indirect surrogate parameters have been proposed, but with only modest clinical usefulness...

PURPOSE: The use of an argatroban-based percutaneous ventricular assist device (pVAD) purge solution in a patient with suspected heparin-induced thrombocytopenia (HIT) is described. SUMMARY: A 70-year-old woman in cardiogenic shock was admitted to a coronary care unit after being discovered unresponsive at home. A transthoracic echocardiogram revealed a low ejection fraction and findings consistent with takotsubo cardiomyopathy. Administration of multiple inotropes and vasopressors was initially required for hemodynamic support...

An asymptomatic 18-year-old black woman was found to have an incidental finding of third-degree atrioventricular (AV) block on a routine ECG. 2-Dimensional transthoracic echocardiography showed a heterogeneous mass in the region of the peri-membranous septum in the AV node area. A cardiac MRI showed a well-defined cystic mass arising from the right side of the interatrial septal wall. An MRI compatible permanent pacemaker was implanted with plans to monitor the tumour with non-invasive imaging. Cystic tumour of the AV node is a rare primary cardiac tumour...

Papillary fibroelastomas (PFEs) are the second most common benign neoplasms of the cardiac valves and are being recognized more frequently because of higher resolution imaging technology. PFEs are associated with substantial complications that are secondary to systemic embolism. Surgical resection should be offered to all patients who have symptoms and to asymptomatic patients who have pedunculated lesions or tumors larger than 1 cm in diameter. Herein, we present a patient who presented for a second time in 2 months with stroke symptoms...

Transcatheter aortic valve replacement (TAVR) is traditionally performed under cardiac imaging guidance. In the early TAVR experience, intra-procedural transoesophageal echocardiography (TOE) is recommended to guide device deployment, in the context of general anaesthesia (GA). Intra-procedural TOE imaging is particularly useful during TAVR deployment as a contrast-saving strategy for patients with renal impairment. Evidence has emerged recently demonstrating that in selected patients, transthoracic echocardiography (TTE) can be used to provide intra-procedural guidance for TAVR...
