Giant coronary artery aneurysm is an uncommon disease, treated with surgical intervention or percutaneous coil embolization. A thrombosed aneurysm can cause extrinsic compression on the cardiac chambers, with potential hemodynamic effects and may cause problems when we need to implant a cardiac device. We present a case of difficult pacemaker implantation in a patient with 3 syncopes, first-degree AV block and complete left bundle branch block on electrocardiogram.

Pheochromocytoma is a rare adrenal tumor characterized by the secretion of catecholamines and vasoactive peptides. It can cause a catecholaminergic storm and lead to acute coronary syndromes. We present the case of a 53-year-old man, without any medical history, who arrived to the hospital following a spinal trauma due a fall.

Andersen-Tawil Syndrome (ATS) is a rare periodic paralysis with typical skeletal and neuromuscular features. Cardiac involvement may range from asymptomatic ventricular arrhythmias to sudden death. Its management remains challenging and the choice between antiarrhythmic drug therapy and implantable cardioverter defibrillator (ICD) is not simple.

We report a case of left atrial extrinsic compression caused by an esophageal food bolus in a patient presenting with acute heart failure. Transthoracic echocardiography along with contrast-enhanced CT showed evidence of esophageal dilation producing left atrial compression. Esophageal endoscopy and fragmentation of the bolus, allowing the accumulated food to descend into the stomach, produced a rapid improvement of hemodynamic and clinical status.

Background: As atrial stiffness (K) is an important determinant of cardiac pump function, better mechanical characterization of left atrial (LA) cavity would be clinically relevant. Pulmonary venous ablation is an option for atrial fibrillation (AF) treatment that offers a powerful context for improving our understanding of LA mechanical function. We hypothesized that a relation could be detected between invasive estimation of K and new non-invasive deformation parameters and traditional LA and left ventricular (LV) function descriptors, so that K can be estimated non-invasively.

Aim: To evaluate the safety and efficacy of the permanent high interventricular septal pacing in a long term follow up, as alternative to right ventricular apical pacing.

Methods: We retrospectively evaluated: (1) 244 patients (74 ± 8 years; 169 men, 75 women) implanted with a single (132 pts) or dual chamber (112 pts) pacemaker (PM) with ventricular screw-in lead placed at the right ventricular high septal parahisian site (SEPTAL pacing); (2) 22 patients with permanent pacemaker and low percentage of pacing (< 20%) (NO pacing); (3) 33 patients with high percentage (> 80%) right ventricular apical pacing (RVA). All patients had a narrow spontaneous QRS (101 ± 14 ms).

Background: Atrial fibrillation (AF) is the most common sustained arrhythmia, with a high recurrence rate, especially during the first months after cardioversion (CV). Few parameters have been evaluated as predictors for the maintenance of sinus rhythm (SR), with limited results. Recently total atrial conduction time (TACT) has been proposed as independent predictor of AF recurrence.

Aims: In the present study, we compare different echocardiographic cardiac dyssynchrony parameters, both of intraventricular and interventricular dyssynchrony, in order to predict response to cardiac resynchronization therapy (CRT).

Methods And Results: In a population of 77 heart failure patients scheduled for CRT, we measured the interventricular mechanical delay (IVMD) and we analyzed six different parameters of intraventricular dyssynchony: the tissue Doppler imaging (TDI) septum-lateral wall delay, the systolic dyssynchrony index; the three-dimensional SD of the time to reach minimum systolic volume for 16 left ventricular segments (3D-SDI); the speckle-tracking radial, circumferential and longitudinal dyssynchrony. At 6 months of follow-up, 61 (79%) patients were responders (≤15% in left ventricular end-systolic volume).

Isolated supravalvular pulmonary stenosis is a rare finding, usually evidenced in the pediatric age. Here, we report a case of a 76-year-old patient with isolated, severely obstructive, pulmonary supravalvular stenosis. The peculiarity of the present case is the paucity of symptoms and lack of changes in right heart sections, despite of the importance of stenosis.

Objectives: We assessed the clinical profile of patients with acute coronary syndrome (ACS) and nonobstructive coronary artery disease (CAD) in a real world setting, focusing on pattern of care and on prognosis.

Methods: Each nonobstructive CAD (<50% stenosis in any epicardial coronary artery) patient was matched with an obstructive CAD patient; adjusted estimates of prescription of guideline-recommended drugs at discharge and of long-term prognosis were evaluated.

Results: Among 2995 consecutive ACS patients who underwent coronary angiography, 125 (4.
