Optical coherence tomography (OCT) is an increasingly available intracoronary imaging modality that provides high-resolution imaging of coronary arteries. Its fundamental reliance on the emission and reflection of light enables rapid data acquisition without compromise of image resolution. As such, OCT can inform operators planning percutaneous coronary intervention (PCI) by accurately defining luminal geometry and detailing plaque composition. Following PCI, OCT imaging delivers a thorough assessment of the treated arterial segment and can identify specific features not always visible on alternate imaging modalities, including stent edge-related dissection, plaque tissue prolapse, incomplete stent apposition and the presence of intra-coronary thrombus...

BACKGROUND: Closure of the left atrial appendage (LAA) to prevent cardioembolic events is an alternative therapy to oral anticoagulation in patients with non-valvular atrial fibrillation. The LAA is an important source of natriuretic peptides and its exclusion from the circulation may alter the blood level of these hormones, thereby influencing their diagnostic value and clinical effects. METHODS: We aimed to prospectively assess potential changes in mid-regional pro A-type natriuretic peptide (MR-proANP) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels six weeks and six months after interventional LAA closure using the Watchman device...

BACKGROUND: New-onset or worsening heart failure is the most common extra-pulmonary complication of community-acquired pneumonia (CAP) during the first 30 days after diagnosis. METHODS: We evaluated the changes in the right ventricular function amongst adult CAP survivors from the time of acute infection to its resolution. We performed comprehensive transthoracic echocardiographic examinations to assess right heart function during the acute illness and the convalescent period (four to six weeks after hospital discharge)...

Blood cysts are benign, congenital tumours of the heart endothelium, found most commonly on heart valves. Adult cases are rare, since most spontaneously regress with age. However, reports of symptomatic cases with embolic phenomena and valve dysfunction have been described. We present a case of a previously healthy 44-year-old woman with no cardiovascular risk factors who developed acute myocardial infarction caused by coronary artery embolism from a blood cyst of the anterior mitral valve leaflet.

BACKGROUND: Atrial fibrillation (AF) is a type of cardiac arrhythmia which is commonly seen following lung resection. There is currently no algorithm which can predict which patients will develop postoperative AF (PAF). The present study aims to identify the risk factors for the development of PAF and high-risk patients with PAF along with multiple risk factors. MATERIALS AND METHODS: A total of 887 patients, who underwent lung resection due to primary lung malignancy at our clinic between January 2000 and December 2016, were retrospectively analysed...

Wenfang Ma, Yan Liang, Jun Zhu
BACKGROUND: Fear of complications related to the procedure and unclear benefits in elderly patients are common reasons for invasive angiography being withheld. METHODS: We searched PubMed and Embase from inception until February 2016 for studies that enrolled individuals older than 75 years with non-ST-elevation acute coronary syndrome (NSTE-ACS) and allocated patients to either an invasive or conservative strategy. RESULTS: Thirteen studies (four randomised controlled trials (RCTs) and nine observational studies) enrolling 832,007 elderly NSTE-ACS patients were analysed...

BACKGROUND: For some patients with atrial fibrillation, direct current cardioversion (DCCV) is one strategy that can be used to establish sinus rhythm but appropriate anticoagulation is mandatory to prevent thromboembolic events. Historically, patients were anticoagulated with warfarin with bridging with unfractionated or low molecular weight heparin, however, recently novel oral anticoagulants (NOACs), apixaban, dabigatran and rivaroxaban have become more popular. Despite the increase in use, real world data on safety and efficacy is limited...

BACKGROUND: Evidence on the long-term clinical benefits of individual members of angiotensin II receptor blockers is limited given the lack of head-to-head studies. We conducted a network meta-analysis to determine the comparative efficacy of different members within this drug class with respect to outcomes of (i) blood pressure reduction (at 24 and 52 weeks) and (ii) prevention of cardiovascular disease (>104 weeks). METHODS: A systematic literature review was conducted - Protocol registration: (PROSPERO - CRD42014007067) - to identify relevant literature from the following databases: Cochrane Library, PubMed, MEDLINE and Embase; searched from inception to July 2016...

BACKGROUND: Primary percutaneous coronary intervention (PPCI) is the preferred therapy for patients presenting with ST-elevation myocardial infarction (STEMI). We reviewed patients undergoing PCI for STEMI over a six-year period to evaluate changes in procedural characteristics and clinical outcomes given recent changes to STEMI guidelines. METHODS: All patients presenting to the Alfred Hospital, a tertiary referral hospital, between 1 January 2010 and 31 December 2015 undergoing PCI for STEMI were identified...

BACKGROUND: An aberrant coronary artery is a rare clinical occurrence with an incidence of 0.05-1.2%. Often it is an incidental finding detected on coronary angiography or at autopsy. However, symptomatic patients can experience angina, arrhythmia, sudden death or non-specific symptoms such as dyspnoea and syncope. At present, there are no guidelines or dedicated studies assessing the treatment of an aberrant coronary artery leaving management options for these patients controversial...

REVIEW
Harry G Mond, Jitendra Vohra
In 1899, Karel Frederik Wenckebach described a cardiac arrhythmia with periodic dropped beats now referred to as a Wenckebach sequence. This was later shown to be due to a block in the atrioventricular node, but today, we identify Wenckebach sequences throughout the heart with most being recognised on the surface electrocardiograph as characteristic footprints. This manuscript will revisit Wenckebach atrioventricular block, the typical features of which only occur in about 15% of cases, with the remainder atypical...

BACKGROUND: We aimed to clarify the pathological characteristics of rheumatic mitral valve disease in Chinese individuals, as well as to determine the appropriate rheumatic mitral valve repair strategy according to such characteristics. METHODS: We obtained detailed statistics regarding the pathological characteristics of patients who underwent mitral valve repair or replacement for rheumatic disease during the past year at our centre. The outcomes of different repair techniques were compared...

BACKGROUND: Due to the advancements in congenital cardiac surgery and interventional cardiology in the last five decades, more than 85% of congenital heart patients now survive to adulthood. METHODS: This retrospective study included 135 Adult Congenital Heart Disease (ACHD) patients, who had cardiac surgery at Southampton General Hospital over three consecutive years. We also included 42 patients with a structurally normal heart who had cardiac surgery for acquired cardiac conditions as a control group...

BACKGROUND: Unroofed coronary sinus syndrome (URCSS) is a spectrum of cardiac anomalies in which part (partial type) or the entire common wall (complete type) between the coronary sinus (CS) and left atrium is absent. It is commonly associated with a persistent left superior vena cava (PLSVC). The PLSVC can even anomalously connect to the left atrium in complete type anomaly. URCSS has been reported to be associated with delayed diagnosis and life-threatening cerebral injury. The purpose of the present study was to review our experience with surgical correction of this often-concealed malformation and discuss methods for reducing diagnostic omission...

BACKGROUND: Prosthetic valve endocarditis is the most severe form of infective endocarditis. This study assessed the risks and challenges of surgery for aortic prosthetic valve endocarditis. METHODS: In total, 116 consecutive patients (98 males, age 65.2±12.7years), who underwent redo-surgery for active aortic prosthetic valve endocarditis between 2000 and 2014, were reviewed. Cox regression analysis was used to identify factors for aortic root destructions as well as for morbidity and mortality...
