Introduction: Mediastinal granulomatous lymphadenopathies, such as tuberculous lymphadenitis, sarcoidosis, are frequently encountered by respiratory physicians, and their diagnosis is based on histological and microbiological tests. Endobronchial ultrasound-guided Trans bronchial needle aspiration (EBUS-TBNA) is widely used to perform mediastinal lymph node sampling. However, very limited data is available on the yield of polymerase chain reaction for Mycobacterium tuberculosis (TB-PCR) using EBUS-TBNA samples in patients with mediastinal granulomatous lymphadenopathy.

Ischemic cardiomyopathy often presents with advanced heart failure necessitating an intensive multidisciplinary approach to management. These patients constitute a very difficult population presenting with angina and ventricular tachyarrhythmias sometimes presenting as sudden cardiac death. In those patients presenting with spontaneous ventricular tachyarrhythmias, treatment with automated intracardiac defibrillator implantation has a significant mortality benefit.

Quadruple-valve repair or replacement is associated with significant morbidity and mortality because the clinical situation of severe disease of all 4 valves implies incipient myocardial damage. We report a case of redo quadruple-valve repair in a patient with rheumatic heart disease who had undergone the Ross procedure 14 years earlier. He presented with heart failure.

The burden of heart failure has long plagued the productive years of the population, with therapeutic advances in the timely treatment of ischemic heart disease decreasing its associated mortality. Angiotensin-converting enzyme inhibitors and β-blockers have impacted heart failure therapeutics in a revolutionary way. The importance of blockade of the renin-angiotensin system and adrenergic stimulation are fully accepted concepts that apply in young and old, symptomatic and asymptomatic, borderline low and very low Ejection Fraction (EF), left ventricular failure and biventricular failure.

Objectives: In patients with previous myocardial infarction, the remote uninfarcted regions, although contractile, demonstrate dysfunctional wall kinetics because of increased afterload, which improves after surgical ventricular restoration (SVR). We characterized left ventricular (LV) mean myocardial velocity (MMV) through an analysis of endocardial motion and wall thickening (WT) over the cardiac cycle using standard cardiac magnetic resonance (cMR).

Methods: LV endocardial motion and WT from cMR data in 7 heart failure (HF) patients with postinfarction antero apical aneurysm were compared against normal controls to establish a baseline for the mean myocardial velocity during phases of the cardiac cycle.

Objective: A hypothesis on left ventricular aneurysms states that there is better preservation of contractile myocardium when the aneurysm geometry is rectangular as opposed to circular. Pre-surgical planning of surgical ventricular restoration was performed on the basis of this hypothesis.

Methods: The intraventricular patch used to exclude scarred or aneurysmal myocardium remains akinetic, hence it was used to define aneurysm geometry as circular or rectangular.

Perioperative anaesthetic management of the VentrAssist™ left ventricular assist device (LVAD) is a challenge for anaesthesiologists because patients presenting for this operation have long-standing cardiac failure and often have associated hepatic and renal impairment, which may significantly alter the pharmacokinetics of administered drugs and render the patients coagulopathic. The VentrAssist is implanted by midline sternotomy. A brief period of cardiopulmonary bypass (CPB) for apical cannulation of left ventricle is needed.
