Left atrial dissection following mass removal from right ventricle: non-surgical therapy

Video-assisted left ventricle mass removal.

Giant Right Atrial Mass Following Surgical Aortic Valve Replacement

Figure 1 – Transthoracic echocardiography: giant eco-dense mass occupying the entire right atrium (Panel A) and severely limiting tricuspid valve inflow (Panel B). Atrial wall and visceral pericardium (arrows) A 75-year-old man underwent elective biological aortic valve replacement. Two weeks after surgery, transthoracic echocardiography (TTE) showed a small pericardial effusion. On the followi...

Ockham's razor or Hickam's dictum: a right atrial mass following excision of left atrial myxoma.

We report a case of a 54-year-old man presenting with a right atrial mass 7 months after undergoing a left atrial myxoma excision surgery. The differential diagnosis included recurrent myxoma or thrombus. The patient underwent repeat open sternotomy on cardiopulmonary bypass. Histopathological evaluation of the mass revealed an organizing thrombus. This report is, to our knowledge, the first th...

persistent isolated right atrial standstill associated with left atrial tachycardia

introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...

Right Atrial Approach for Ablation of Ventricular Arrhythmias Arising From the Left Posterior-Superior Process of the Left Ventricle.

BACKGROUND The posterior-superior process of the left ventricle (PSP-LV) is the most inferior and posterior aspect of the basal LV that extends posteriorly to the plane of the tricuspid valve. The PSP-LV is anatomically adjacent to the inferior and medial aspect of the right atrium (RA). We report a series of patients with ventricular arrhythmias (VAs) arising from the PSP-LV and describe a map...
