A 19-year-old patient with premature ventricular complexes (PVCs) more than 30% on 24 hours was addressed for catheter ablation. Echocardiography showed left ventricular (LV) dilation and systolic dysfunction with 37% of ejection fraction. The patient underwent investigations including cardiac magnetic resonance (MRI) with no other cause of cardiomyopathy being found. Successful ablation of the postero-lateral tricuspid annulus ectopic focus using conventional radiological guiding resulted in normalization of the LV size and contractility. No PVCs were found at follow-up. To our knowledge, this is the first report of PVCs originating in the postero-lateral tricuspid annulus resulting in LV dysfunction.

Left ventricular pseudoaneurysm (LVPA) formation is a potentially lethal complication of myocardial infarction (MI) and mitral valve (MV) replacement that requires prompt diagnosis and treatment. A female patient who had been complaining of exertional dyspnea underwent a two-dimensional transthoracic echocardiogram (TTE) which revealed a functioning mechanical MV with severe paravalvular leak, severe tricuspid regurgitation (TR) and severely elevated pulmonary artery systolic pressure. Moreover, echo-lucent space at the postero-lateral portion of the left ventricle near the MV was seen, suggestive of a large LVPA.

Since the advent of percutaneous coronary intervention there have been increasing numbers of patients with so-called 'full metal jacket' coronary arteries disease. This is creating a challenging problem for the cardiac surgeon. A 73 year-old woman after the implantation of two metal stents to the left anterior descending artery (LAD) and four to the right coronary artery (RCA), with ejection fraction of 28%, significant mitral and tricuspid insufficiency, and high systolic pulmonary pressure, was admitted to our department with unstable angina and with symptoms of pulmonary oedema.

Objective: To demonstrate that the use of a 20-pole catheter (Halotrade mark) positioned around the tricuspid valve annulus (TVA) is helpful in rapidly localising right free wall accessory pathways (AP), enhancing catheter stability during ablation, and leading to increased success in ablating these challenging pathways.
Patients And Methods: Seven consecutive patients who underwent Halo-mapping of right-sided AP were studied. All but one had previously failed ablation.
