Cardiac masses are rare and of the neoplastic group, myxomas are the most common. An elderly male with a background of multiple myeloma and previous autologous stem cell transplant presented with dyspnea and chest heaviness with a subsequent cardiac mass found. Multimodal imaging, including three-dimensional (3D) echocardiography and cardiac magnetic resonance (CMR) imaging, was utilized to guide the diagnostic process, particularly given the differential of a cardiac plasmacytoma in the setting of multiple myeloma.

The stent balloon inflation technique or material properties may influence the degree of CMD post-PCI.
Methods: Thirty-six patients with stable angina attending for elective PCI were randomized to either slow drug eluting stent (DES) implantation technique (DES slow group): +2 atm.
Background Post-percutaneous coronary intervention (PCI) fractional flow reserve ≥0.90 is an accepted marker of procedural success, and a cutoff of ≥0.95 has recently been proposed for post-PCI instantaneous wave-free ratio.

For most people, it is a benign finding; however, in some people, the PFO can open widely to enable paradoxical embolus to transit from the venous to arterial circulation, which is associated with stroke and systemic embolisation. Percutaneous closure of the PFO in patients with cryptogenic stroke has been undertaken for a number of years, and a number of purpose-specific septal occluders have been marketed.

We present a case of left circumflex (LCx) coronary artery dissection causing inferoposterior ST-elevation myocardial infarction following radiofrequency (RF) ablation for atrial fibrillation (AF) in a 39-year-old male with no cardiovascular risk factors. This was confirmed on coronary angiography and intracoronary vascular ultrasound (IVUS).

The aim of this study was to assess the correlation and agreement of Doppler calculation of right ventricular systolic pressure (RVSP) and pulmonary vascular resistance (PVR) using "chin" and "beard" measurements of tricuspid regurgitant velocity (TRV ), with invasive pulmonary artery systolic pressure (PASP) and PVR.
Methods: One hundred patients undergoing right heart catheterisation (RHC) and near simultaneous transthoracic echocardiography were studied.
Mitral regurgitation (MR) is a valvular heart disease associated with significant morbidity and mortality. Transcatheter mitral valve intervention (TMVI) repairs or replaces the mitral valve through small arterial and venous entry sites and so avoids risks associated with open heart surgery. Transcatheter devices targeting components of the mitral apparatus are being developed to repair or replace it.

We present the first Australian single centre experience of patients treated with Melody TPV.
Method: A prospective, observational registry was developed to monitor clinical and haemodynamic outcomes in patients with RVOT dysfunction treated with the Melody TPV (Medtronic Inc, Minneapolis, United States).
Background: Cardiac Troponin I (cTnI) is frequently measured in patients presenting with symptomatic atrial fibrillation (AF). The significance of elevated cTnI levels in this patient cohort is unclear. We investigated the value of cTnI elevation in this setting and whether it is predictive for significant coronary artery disease (sCAD).
