Reports of spontaneous pneumothorax in patients with coronavirus disease 2019 (COVID-19) suggest that the COVID-19 infection could itself cause pneumothorax in addition to the ventilator-induced trauma among mechanically ventilated patients. Here, we report a case series of five mechanically ventilated patients with COVID-19 infection who developed pneumothorax. Consecutive cases of intubated patients in the intensive care unit with the diagnosis of COVID-19 pneumonia and pneumothorax were included. Data on their demographics, preexisting risk factors, laboratory workup, imaging findings, treatment, and survival were collected retrospectively between March and July 2020. Four out of five patients (4/5; 80%) had a bilateral pneumothorax, while one had a unilateral pneumothorax. Of the four patients with bilateral pneumothorax, three (3/4; 75%) had secondary b...

Options for imaging include transthoracic or transesophageal echocardiography and intracardiac echocardiography, with appropriate use being dictated by specific patient characteristics and institutional experience. The authors present a case of three-dimensional (3-D) transesophageal echocardiography-guided transcatheter biopsy of a right ventricular mass and review the current use of echocardiography to guide these procedures.

Using ultrasoundfacilitated thrombolysis (UFT), a thrombolytic agent is delivered through an infusion catheter that also emanates high frequency, lowpower ultrasonic waves which disrupt the thrombus. This exposes a greater amount of thrombin receptors and allows for the delivery of recombinant tissue plasminogen activator (rt-PA) deeper into the thrombus. This enhances the local effect of the drug. It allows better absorption of the rt-PA by the thrombus when compared to cases where ultrasound was not used. UFT reduces the time to complete thrombolysis with minimal distal embolization or hemolysis. This minimizes the period of right ventricular (RV) dysfunction and hence overcomes the delay in the recovery of the RV function that is seen in patients treated just with therapeutic anticoagulation regimens or conventional thrombolytic protocols not enhanced by ultrasound. 5 Two-dimensional transthoracic echocardiography (2DTTE) is a noninvasive, readily available modality that can be used even

Our case involves a 35-year-old female patient born and raised in India who recently migrated to the United States. Her echocardiogram revealed severe combined aortic and mitral valve stenosis and severe aortic regurgitation. We hereby analyze echocardiographic findings in concomitant rheumatic aortic and mitral valve disease with preserved left ventricular (LV) systolic function. We also discuss treatment implications with combined surgical replacements of both valves with mechanical prostheses.Cardiovasc. j. 2018; 11(1): 81-85

An estimated 8000 patients will undergo tricuspid surgery annually, leaving a large number of patients with this condition untreated. Many of these individuals who are not referred for surgery engender a large unmet clinical need; this may be primarily due to the surgical risk involved. In persons who are categorized as high-risk surgical candidates, percutaneous procedures present a viable alternative. The majority of developmental attention as regards percutaneous approaches has been focused on the aortic and mitral valves recently, but few data are available about the feasibility and efficacy of minimally invasive tricuspid valve treatment. We review the usefulness of two- and three-dimensional echocardiography in the assessment of the tricuspid valve with special reference to recent interest in percutaneous repair and prosthetic valve implantation procedures for severe funct...

A comprehensive assessment of mitral regurgitation using different echocardiographic techniques provides important information regarding the etiology and severity of mitral regurgitation and its consequences on cardiac function. In addition, echocardiography plays an important role in the management of patients with mitral regurgitation.
