Electrocardiographic voltage criteria in patients with hypertrophic cardiomyopathy.

Background: Several ECG voltage criteria have been proposed for the diagnosis of left ventricular hypertrophy (LVH). Notably, ECG criteria have been historically validated in concentric LVH but not in hypertrophic cardiomyopathy (HCM), wherein the hypertrophy pattern is typically asymmetric.

Objectives: The aim of our study was to evaluate the performance of ECG voltage criteria for LVH diagnosis in the HCM population.

Coronary Artery Fistula Diagnosed by Echocardiography during NSTEMI: Case Report and Review of Literature.

Coronary artery fistulas are rare abnormal connections between a coronary artery and a cardiac chamber or a major vessel. Often, they are asymptomatic and the diagnosis is accidental. The case we present is the incidental finding of a fistula displayed with echocardiography during acute coronary syndrome (ACS).

Left ventricular surgical remodelling: is it a matter of shape or volume?

Objective: Left ventricular surgical remodelling (LVSR) can be targeted to volume reduction (VR), (independently of the final shape) or to conical shape (CS). The aim of this study was to evaluate the long-term clinical and echocardiographic results of these two surgical strategies.

Methods: From January 1988 to December 2012, 401 patients underwent LVSR: 107 in Group VR (1988-2001) and 294 in Group CS (1998-2012).
