Impact of same-admission percutaneous coronary intervention on periprocedural outcomes of transcatheter aortic valve implantation.

Background: Current guidelines recommend percutaneous coronary intervention (PCI) prior to transcatheter aortic valve implantation (TAVI) if significant coronary artery disease is present, but whether PCI should be done in the same admission as TAVI is not determined.

Methods: We retrospectively analyzed the National Inpatient Sample from 2016 to 2019 to compare TAVI with and without same-admission PCI and compare in-hospital outcomes after propensity score matching.

Results: Among 170,030 hospitalizations for TAVI, 4425 (2.

Deep learning model to predict the need for mechanical ventilation using chest X-ray images in hospitalised patients with COVID-19.

Objectives: There exists a wide gap in the availability of mechanical ventilator devices and their acute need in the context of the COVID-19 pandemic. An initial triaging method that accurately identifies the need for mechanical ventilation in hospitalised patients with COVID-19 is needed. We aimed to investigate if a potentially deteriorating clinical course in hospitalised patients with COVID-19 can be detected using all X-ray images taken during hospitalisation.

Ruptured Sinus of Valsalva Aneurysm: Use of Multimodality Imaging in Delineating Structure and Function.

Sinus of Valsalva aneurysm is a rare defect that can present with fatal complications in case of rupture. Heart failure symptoms are common due to high fraction of the resultant shunt. Multimodality imaging and invasive hemodynamic assessment is essential for comprehensive evaluation of the defect and guiding surgical planning.

Clinical predictors and outcomes of patients with pericardial effusion in chronic kidney disease.

Background: Pericardial effusion is common in hospitalized patients with chronic kidney disease (CKD). We sought to identify predictors and prognostic impact of pericardial effusion in CKD patients.

Hypothesis: Clinical and biochemical parameters can predict pericardial effusion in CKD patients.

Variant origin and course of left circumflex coronary artery.

Variant origin of left circumflex coronary artery (LCx) from right aortic sinus is a well-recognized coronary variation, usually without any clinical consequences. However, the variant origin and trajectory of the artery may have major implications during percutaneous coronary intervention, coronary artery surgery, aortic and mitral valve replacement procedures. We observed a variant LCx in a heart specimen belonging to 45-year-female with no history of hypertension, diabetes mellitus and coronary artery disease.

Spatial relationship of coronary sinus-great cardiac vein to mitral valve annulus and left circumflex coronary artery: implications for cardiovascular interventional procedures.

Background: The spatial relationship of the coronary sinus-great cardiac vein (CS-GCV) to free posterior portion of the mitral valve annulus (MVA) and left circumflex coronary artery (LCx) has gained importance with the advent of cardiovascular interventional procedures such as percutaneous transvenous mitral annuloplasty (PTMA) and mitral isthmus (MI) ablation.

Methods: In 50 normal (nondilated cardiomyopathy, or non-DCM) and 20 dilated cardiomyopathy (DCM) cadaveric hearts, the diameter and distance from the MVA of CS-GCV and its spatial relationship to LCx along the free posterior portion of the MVA were studied.

Results: The diameter of the CS-GCV increased from the beginning to termination in both non-DCM and DCM cases.

Diagnostic and prognostic significance of ischemic electrocardiographic changes with regadenoson-stress myocardial perfusion imaging.

Background: The diagnostic and prognostic value of regadenoson-induced ST-segment depression (ST↓) is not defined. Due to the low incidence of ST↓ ≥1.0 mm with vasodilator stress, a lower threshold to define ischemic ECG response may provide improved clinical utility.

Diagnostic accuracy retrospectively of electrocardiographic findings and cancer history for tamponade in patients determined to have pericardial effusion by transthoracic echocardiogram.

Unexpected pericardial effusions are often found by frontline providers who perform computed tomography. To study the hypothesis that electrocardiographic findings and whether cancer is known or suspected importantly change the likelihood of tamponade for such providers, all unique patients with moderate or large pericardial effusions determined by transthoracic echocardiography during a 6-year period were retrospectively identified. Electrocardiograms were evaluated by blinded investigators for electrical alternans (total and QRS), low voltage (limb leads only, precordial leads only, and both), and tachycardia (>100 QRS complexes/min).

Magnetocardiography for the diagnosis of coronary artery disease: a systematic review and meta-analysis.

Background: Coronary artery disease (CAD) has a significant disease burden making early diagnosis and management imperative. Magnetocardiography (MCG) is a relatively new noninvasive technique that allows diagnosis of CAD by recording the magnetic fields generated by the electrical activity of the heart.

Methods: We searched MEDLINE and the Cochrane Central Register of Controlled Trials for prospective studies that evaluated the test characteristics (e.

Terminal branching pattern of the right coronary artery in left-dominant hearts: a cadaveric study.

Background: Left coronary dominance has been reported to be associated with increased mortality and severity in case of myocardial ischemia involving left coronary artery. The present cadaveric study was proposed to objectively study and document the termination and branching pattern of the right coronary artery in left-coronary-dominant hearts in relation to the blood supply to the posterior surface of the right ventricle.

Methods: Seventy-five cadaveric hearts were studied.
