Randomized Controlled Trial
Feasibility and reliability of point-of-care pocket-sized echocardiography.
To study the reliability and feasibility of point-of-care pocket-sized echocardiography (POCKET) at the bedside in patients admitted to a medical department at a non-university hospital. ⋯ http://www.clinicaltrials.gov; unique ID: NCT01081210.

A 59-year-old man had, over a period of 5 years, three different clinical scenarios which led to dynamic left ventricular outflow tract obstruction (LVOTO). Initially, this man who suffered from hypertrophic cardiomyopathy presented with asymmetric septal hypertrophy and systolic anterior motion (SAM) of the anterior mitral leaflet, along with mitral regurgitation. He was treated by septal myectomy and mitral valve repair with insertion of an artificial mitral ring. ⋯ The ring and the anterior mitral leaflet were resected and a prosthetic mitral valve implanted. Several years later, the patient presented with LVOTO for a third time. It was now SAM of the remaining posterior leaflet that was responsible for the LVOTO.

To identify a correction of the modified Bernoulli formula used to estimate systolic and mean pulmonary artery pressure [sPAP and mPAP; respectively: sPAP = 4 × TRv (tricuspid regurgitation velocity)(2)+ RAP (right atrial pressure); and mPAP = 0.61sPAP + 2], applicable in the follow-up of pulmonary hypertension (PH) patients. ⋯ Our data suggest that formulas (1) and (2) could be more reliable with respect to the traditional modified Bernoulli equation, when estimating echocardiographically sPAP and mPAP in patients with PH confirmed by right-heart catheterization.

Left ventricular (LV) dysfunction is the first cause of late mortality after mitral valve surgery. In this retrospective analysis, we studied the association between preoperative echocardiographic LV measures and occurrence of LV dysfunction after mitral valve repair (MVR). ⋯ Simple preoperative echocardiography measures allow the prediction of LV dysfunction after MVR in patients with leaflet prolapse. Patients with preoperative EF ≥ 64% and LVESD < 37 mm incur relatively low risk of post-operative LV dysfunction.
