COVID-19 diagnosis in a patient with critical limb ischemia: complications and clinical outcomes.

A 67-year-old male diabetic patient with systemic arterial hypertension was admitted to the emergency department with a necrotic ulcer in the left external malleolus and no palpable popliteal or pedal pulses. Arterial Duplex ultrasound identified femoropopliteal occlusion, with popliteal refilling below the knee and a patent peroneal artery. An endovascular procedure was performed, requiring retrograde access to the popliteal artery to re-establish blood flow and deploy a popliteal stent.

[Long-term follow-up in patients operated on for aortic coarctation. The echo-Doppler and MRI assessment of left ventricular function and the transisthmic gradient].

Background: Hyperdynamic left ventricular function and increased left ventricular mass has been recently reported in the long-term follow-up of patients after successful repair of aortic coarctation (AoCo).

Methods: We studied 35 patients, mean age 22.7 years (range 1-47), following repair of AoCo in order to evaluate: 1) left ventricular mass and systolic function by M-mode echocardiography in comparison with 20 healthy control subjects; 2) the prevalence of systemic hypertension; 3) systolic blood pressure and the trans-isthmic gradient by CW Doppler at rest and after exercise; 4) subjects with a hypertensive response and/or with a significant trans-isthmic gradient during exercise, correlating such parameters with indexes of left ventricular function and the ratio of aortic isthmus/aortic diaphragmatic diameters (AOI/AOD) by means of Magnetic Resonance (MR).

[Transesophageal echocardiography in the diagnosis of cor triatriatum in the adult].

Cor triatriatum (CT) is a rare congenital defect, surgically correctable, and sometimes difficult to diagnose by cardiac catheterization. This report describes three young patients with this particular defect, one of whom was sent to us because of signs of right ventricular failure. The diagnosis of CT was made by transesophageal echocardiography and confirmed by cardiac catheterization and surgical data.

[Value of the isovolumetric index in the diagnosis of ischemic cardiopathy with normal left ventricular volume and ejection fraction].

Purpose of this study was to assess if the isovolumic index (IVI%) was able to detect the presence of critical coronary artery disease (CAD) in a group of 43 patients with anginal chest pain and normal left ventricular volumes and ejection fraction. The left ventricular function was before evaluated with invasive method and then the IVI% was allowed in every patient. The IVI% was able to recognize early abnormalities of isovolumetric phases of the left ventricle and differentiated normal subjects (IVI% = 40.

[The isovolumetric index: a new index of left ventricular function].

The isovolumic index (IVI%), a new parameter of left ventricular function defined as (isovolumic contraction + isovolumic relaxation time)/left ventricular ejection time, is easily obtained from a routine echocardiogram. By simultaneous recordings of an electrocardiogram, a carotid arterial pulse tracing and the mitral valve echocardiogram, we calculated the IVI% as (time from R wave to MV opening-LVET)/LVET %. 90 normal subjects, mean age 38.
