Snoring Survivors: the impact of obstructive sleep apnoea and continuous positive airway pressure use on in-hospital mortality, length of stay and costs among patients hospitalised with acute cardiovascular disease - A retrospective analysis of 2016-2019 National Inpatient Sample Data.

Background: The routine administration of supplemental oxygen to non-hypoxic patients with acute myocardial infarction (AMI) has been abandoned for lack of mortality benefit. However, the benefits of continuous positive airway pressure (CPAP) use in patients hospitalised with acute cardiovascular disease and concomitant obstructive sleep apnoea (OSA) remain to be elucidated.

Methods: In this retrospective case-control analysis, using 10th International Classification of Diseases, Clinical Modification (ICD-10) codes, we searched the 2016-2019 Nationwide Inpatient Sample for patients diagnosed with unstable angina (UA), AMI, acute decompensated heart failure (ADHF) and atrial fibrillation with rapid ventricular response (AFRVR), who also carried a diagnosis of OSA.

Annular Rupture Due to Calcified Nodule Located in Left Ventricular Outflow Tract (LVOT) During Transcatheter Aortic Valve Replacement (TAVR) Managed by Protamine Sulfate.

Annular rupture is a rare yet fatal complication of transcatheter aortic valve replacement (TAVR). The likelihood of annular rupture is increased by the presence of extensive subannular calcification, excessive balloon dilatation for valve expansion or aggressive valve oversizing to prevent paravalvular leakage during TAVR. Although extensive annular or aortic root calcification increases the likelihood of annular rupture, rupture due to the presence of a calcified nodule in the left ventricular outflow tract (LVOT) is not commonly reported.

Non-surgical extirpation of a non-infectious expanding tricuspid valve mass by percutaneous aspiration thrombectomy.

Marantic endocarditis refers to a noninfectious lesion, usually in the aortic and mitral valves, that is most commonly seen in advanced malignancy and systemic lupus erythematosus. Inflammatory conditions, including antiphospholipid syndrome (APS), are a rare etiology making up less than 20% of reported cases. The condition is thought to be due to a hypercoagulable state and found postmortem with rates in autopsy series ranging from 0.

Improving the positive predictive value of exercise testing in women for coronary artery disease.

The exercise treadmill test (ETT) in women has been limited by a low positive predictive value (PPV) for coronary artery disease (CAD). However, the reliability of previous studies was unsatisfactory because of the inclusion of younger women with a low prevalence of CAD. To further evaluate the diagnostic properties of the ETT in women, we evaluated a group of women with chest pain who had a positive ETT result and subsequent coronary angiography.
