Atherosclerotic Coronary Artery Disease in a Younger Adult With Transseptal Anomalous Left Coronary Artery.

We present a case of extensive coronary atherosclerotic disease in a younger patient with an anomalous left coronary artery with transseptal course and show the utility of multimodality evaluation to determine the culprit lesion in patients presenting with this rare association. (Level of Difficulty: Intermediate.).

Electromagnetic interference induced ventricular tachycardia in left ventricular assist device.

Left ventricular assist devices (LVAD) have been increasingly utilized end-stage heart failure despite guidelinedirected medical therapy (due to limited organ availability) as a bridge to transplant or destination therapy, with improved overall survival.Majority of patients undergoing LVAD implantation have pre-existing implantable cardioverter-defibrillator (ICD) in-situ.We present a case of device-device interaction resulting in EMI inducing recurrent inappropriate device therapies inducing ventricular arrhythmia followed by the inappropriate triggering of noise reversion mode, thereby inhibiting device therapies.With the increase in number of end-stage heart failure patients with ICDs in situ (and limited organ availability) undergoing LVAD implantation, it is imperative to recognize potential device-device interactions to avoid unwarranted invasive interventions.

Trial of Oral Diuretics Prior to Discharge Is Not Associated With Improved Outcomes in Decompensated Heart Failure.

BACKGROUND: Current heart failure guidelines recommend transition of intravenous (IV) diuretics to oral > 24 h prior to hospital discharge. The aim of this study was to determine whether transition to oral diuretics prior to discharge in patients hospitalized with decompensated systolic heart failure (SHF) was associated with improved 30-day events. METHODS: This was a retrospective cohort study, in which adults admitted to the Loma Linda Medical Center for 3 - 14 days with a primary discharge diagnosis of acute on chronic SHF were included. Mortality data were obtained from the National Death Index, while readmission only to our facility was included. The t-test and Chi-square test were used for analyses. RESULTS: A total of 314 patients were studied. Patients who were managed with guideline-recommended trial of oral diuretics, and patients who continued to receive IV diuretics on the last full hospital day were overall similar in baseline characteristics. Patients who received oral diuretics on the day prior to discharge had longer length of stay, less weight loss, were discharged on lower diuretic doses (all P < 0.05), and had similar outcomes of 30-day readmission and 30-day hospitalization-free survival. CONCLUSIONS: The transition to oral diuretics prior to discharge in patients with decompensated SHF was not associated with improved 30-day outcomes. These results require validation in prospective trials but suggest that guideline recommendations regarding transitioning to oral diuretics prior to discharge may deserve re-evaluation.

Role of Guideline Directed Medical Therapy Doses and Optimization in Patients Hospitalized With Decompensated Systolic Heart Failure.

Despite significant advances in evidence-based treatments for heart failure with reduced ejection fraction (HFrEF), the use of guideline directed medical therapy (GDMT) at recommended doses remains suboptimal. We examine the usage and modification of inpatient GDMT and its effect on outcomes in patients hospitalized with a diagnosis of acute on chronic HFrEF between 2013 and 2018. Overall use and modification of GDMT, which included heart failure appropriate beta-blockers (BB), renin-angiotensin system inhibitors (RASi) and aldosterone blockers (MRA) during the hospitalization were collected. Target dosages were based on guideline recommendations. Primary endpoints included 30-day hospitalization-free survival and 1-year survival. Among 1,655 patients, discharge use of BB, RASi, and MRA was 73.4%, 55.9% and 13.8%, respectively. Upon discharge, ≥50% target dose of BB, RASi, and MRA was used in 25.3%, 15.6%, and 13.7%, respectively. In multivariable analyses, there was a statistically significant improvement in 1-year survival and 30-day hospitalization-free survival in patients discharged on increasing number of medication classes optimized at ≥50% target dose (per extra medication, HR 0.74, 0.64-0.86, p <0.001, and HR 0.73, 0.62-0.86, p = 0.0002), respectively. Initiation and/or uptitration of BB and RASi was associated with improved 30-day hospitalization-free survival and 1-year survival, (HR 0.73 (0.57-0.92), p = 0.0087; HR 0.62 (0.46-0.82), p <0.001) for BB and (HR 0.77 (0.62-0.95), p <0.001; HR 0.62 (0.48-0.80), p <0.001) for RASi, respectively. In conclusion, inpatient optimization of GDMT in acute HFrEF is feasible and associated with improved 30-day hospitalization-free survival and 1-year survival.

Diffuse coronary artery vasospasm in a patient with subarachnoid hemorrhage: A case report.

BACKGROUND: Coronary artery vasospasm (CAV) is a reversible, transient form of vasoconstriction with clinical manifestations ranging from stable angina to acute coronary syndromes (ACS). Vasospasm of epicardial coronary arteries or associated micro-vasculature can lead to total or subtotal occlusion and has been demonstrated in nearly 50% of patients undergoing angiography for suspected ACS. The mechanism for CAV has been described in literature, but in a subgroup of patients presenting with intracranial hemorrhage, it appears to be multifactorial. These patients tend to have electrocardiographic changes, elevation of cardiac biomarkers of injury and neurogenic stress cardiomyopathy. CASE SUMMARY: A 44-year-old woman presented with severe headaches and tonic-clonic seizures. She was found to have diffuse subarachnoid hemorrhage (SAH) requiring ventricular drain placement, coil embolization and induced hypertension. She subsequently developed chest pain with ST elevations in anterior precordial leads, elevated cardiac enzymes and apical ballooning with left ventricular ejection fraction of 35% on transthoracic echocardiogram. Coronary angiogram revealed severe diffuse triple vessel stenoses secondary to CAV seen distally. Subsequent cardiac MRI notable for apical non-viability and scar formation. CONCLUSION: This case highlights a unique etiology of acute myocardial infarction in a patient with SAH leading to ST elevations, diffuse triple vessel CAV and apical scar.

Idiopathic omental infarction: managed conservatively.

We report a case of a 49-year-old woman who presented with acutely worsening episodic abdominal pain. Workup was negative but CT of the abdomen showed right upper quadrant omental fat stranding, suggestive of fat necrosis or infarct. Treatment for the patient was largely supportive with pain management and fluid resuscitation.
