Reasons for repeat urgent cardiac procedures within the same day.

BACKGROUND: With advances in technology and technique, the expectations are that patients undergoing procedures in the cardiac catheterization laboratory will not need to return for a repeat procedure within the same day. OBJECTIVES: Report why subjects undergoing cardiac procedures return urgently to the catheterization laboratory for a repeat procedure during the same day. METHODS: We retrospectively reviewed patients who were brought back to the cardiac catheterization laboratory within the same day for a repeat procedure. The reasons for index and repeat procedure were identified. Patients who were transferred from an outside center after an initial procedure at other centers were excluded. RESULTS: Between November 2013 and January 2022, 55,942 catheterization procedures were performed at our institution, of which 140 entries were included in our analysis. Common reasons for the index procedure were diagnostic angiography (35.0%), percutaneous coronary intervention (PCI, 29.2%), and transcatheter aortic valve replacement (15.0%). The most common reason for bringing these patients back to the cardiac catheterization laboratory within the same day was vascular complications (24.2%), followed by repeat PCI (20.7%), need for hemodynamic support (15.0%), heart team discussion and PCI (10%), and pacemaker implantation (10%). Acute limb ischemia was the most commonly identified vascular complication (7.1%), followed by pseudoaneurysm (5%). CONCLUSION: Our study demonstrates that a very small number of patients underwent repeat procedures within the same day. Special attention should be paid to vascular access and closure and assessment of recurrent chest pain postprocedure, as these are the main reasons for same-day repeat procedures.

Early Ventricular Arrhythmias After Left Ventricular Assist Device Implantation.

BACKGROUND: Although sustained ventricular arrhythmias (VAs) are a common complication after durable left ventricular assist device (LVAD) implantation, the incidence, risk factors, and prognostic implications of postoperative early VAs (EVAs) in contemporary patients with LVAD are poorly understood. METHODS AND RESULTS: A single-center retrospective analysis was performed of patients who underwent LVAD implantation from October 1, 2006, to October 1, 2022. EVA was defined as an episode of sustained VA identified ≤30 days after LVAD implantation. A total of 789 patients underwent LVAD implantation (mean age 62.9 ± 0. years 5, HeartMate 3 41.4%, destination therapy 43.3%). EVAs occurred in 100 patients (12.7%). A history of end-stage renal disease (odds ratio [OR] 5.6, 95% confidence interval [CI] 1.45-21.70), preoperative electrical storm (OR 2.82, 95% CI 1.11-7.16), and appropriate implantable cardiac defibrillator therapy before implantation (OR 2.8, 95% CI 1.26-6.19) are independently associated with EVAs. EVA was associated with decreased 30-day survival (hazard ratio 3.02, 95% CI 1.1-8.3, P = .032). There was no difference in transplant-free survival time between patients with and without EVAs (hazard ratio 0.82, 95% CI 0.5-1.4, P = .454). CONCLUSIONS: EVAs are common after durable LVAD implantation and are associated with an increased risk of 30-day mortality.

Coronary Artery Dissection and Myocarditis Caused by Eosinophilic Granulomatosis with Polyangiitis (EGPA): A Case Report.

Eosinophilic granulomatosis with polyangiitis (EGPA) also referred to as Churg-Strauss syndrome is a rare vasculitis of the small to medium vessels. We present a rare case of acute coronary artery dissection brought on by EGPA, which generally has a poor prognosis. A 41-year-old male with history of bronchial asthma presented to the emergency room with a 2-week history of dyspnea, cough with clear phlegm, and fever. For the past eight months he had experienced episodes with similar symptoms relieved by steroids. CT chest showed bilateral upper lobe patchy opacities with extensive workup for infectious etiology being negative. He had peripheral eosinophilia with sinusitis. He had acute coronary syndrome and Coronary angiogram showed Right coronary artery dissection. After making a diagnosis of EGPA based on American college of Rheumatology criteria, he was successfully treated with high dose immunosuppression. Coronary artery dissection is a fatal and uncommon complication of EGPA which is usually diagnosed postmortem. Early recognition of this condition ante mortem and aggressive treatment can be lifesaving as demonstrated in our case.

The Use of Telemedicine to Improve Hypertension in an Urban Primary Care Clinic and Predictors of Improved Blood Pressure.

BACKGROUND AND OBJECTIVE: Meta-analysis of randomized controlled trials have demonstrated the efficacy of telemedicine in blood pressure (BP) management when compared to conventional care. We initiated a hypertension telehealth clinic in our urban primary care clinic and through this study aim to evaluate the strengths and limitations of telemedicine in hypertension (HTN) control. The primary outcome of the study is to identify the proportion of patients with improved HTN. Secondary outcomes included identifying: predictors for lower BP, predictors of missing telehealth appointments, and comorbid conditions that are more likely to necessitate use of more than 1 antihypertensive medication. METHODS AND ANALYSIS: Patients seen in the HTN telehealth clinic from May 1st, 2022 to October 31st, 2022 were identified. A retrospective chart review was done to compare the BP during in-person visit prior to first telehealth visit, telehealth visit home BP readings and last recorded in-office BP on chart at end of study period. Descriptive statistical analysis, Chi Square test, and multivariable logistic regression was used to analyze data. RESULTS: Of the 234 appointments, 83% were conducted and 154 patients were seen. A remarkable decrease in percentage of patients with BP >140/90 was seen when comparing in-office visit BP to first telehealth visit home BP, 72% versus 45% respectively. No remarkable difference was noted in percentage of patients with BP >140/90 when comparing first telehealth visit home BP to last in-office BP recorded on chart, 45% and 41% respectively. Patients with diabetes had lower odds of missing appointments, adjusted odds ratio (aOR): 0.34 ([0.12-0.91], P = .03). Patients with partners were more likely to have lower BP at the telehealth visit, aOR:3.2 ([1.15-9.86], P = .03) while patients with obstructive sleep apnea (OSA) (aOR 0.27 ([0.08-0.77], P = .02) and CAD, aOR 0.24 ([0.06-0.8], P = .03) were less likely to have lower BP. CONCLUSION: The study demonstrated telemedicine as a great tool to prevent overtreatment of hypertension as significant difference between in-office BP and home BP during telehealth visits was noted. We did not see a significant change in blood pressure when comparing home BP at first telehealth visit to the last in-person clinic BP at end of study period.

Impact of Preoperative Echocardiograms on In-Hospital Outcomes of Patients Undergoing Surgical Hip Fracture Repair and Their Clinical Appropriateness.

OBJECTIVES: Preoperative transthoracic echocardiograms (TTE) before hip fracture repairs are controversial. This study aimed to quantify the frequency of ordering TTE, the appropriateness of testing based on current guidelines, and the impact of TTE on in-hospital morbidity and mortality outcomes. METHODS: This retrospective chart review of adult patients admitted with hip fracture compared the length of stay (LOS), time to surgery, in-hospital mortality, and postoperative complications between TTE and non-TTE groups. TTE patients were risk stratified using the Revised Cardiac Risk Index (RCRI) to compare TTE indication according to current guidelines. RESULTS: Of the 490 patients included in this study, 15% received preoperative TTE. The median LOS of the TTE and non-TTE groups was 7.0 and 5.0 d, respectively, whereas the median time to surgery was 34 and 14 h, respectively. The odds of in-hospital mortality remained significantly higher in the TTE group after adjusting for RCRI but not when adjusted for the Charlson Comorbidity Index. Significantly more patients in the TTE groups had postoperative heart failure and up triage in the intensive care unit. Furthermore, 48% of patients with an RCRI score of 0 received preoperative TTE, with cardiac history as the most typical indication. TTE changed perioperative management in 9% of patients. CONCLUSIONS: Patients subjected to TTE before hip fracture surgery had a longer LOS and time to surgery, with higher mortality and intensive care unit up triage rates. TTE evaluations were typically conducted for inappropriate indications, which rarely made meaningful changes to patient management.

Case Report: A Case of Post-Transplant Chagas Reactivation after Negative Trypanosoma cruzi Testing.

Patients with Chagas cardiomyopathy carry a significant risk of reactivation after heart transplantation. Reactivation of Chagas disease can lead to graft failure or systemic complications such as fulminant central nervous system disease and sepsis. As such, careful screening for Chagas seropositivity prior to transplant is crucial to preventing negative outcomes in the post-transplant setting. One challenge in screening these patients is the variety of laboratory tests available and their differing sensitivities and specificities. In this case report, we present a patient who tested positive by a commercial Trypanosoma cruzi antibody assay and later tested negative by CDC confirmatory serological analysis. After the patient underwent orthotopic heart transplant, he underwent protocol-based polymerase chain reaction surveillance for reactivation as a result of persistent concerns for T. cruzi infection. It was discovered shortly thereafter that the patient had reactivation of Chagas disease, confirming that he did have Chagas cardiomyopathy prior to transplantation, despite negative confirmatory testing. This case illustrates the complexities of serological diagnosis of Chagas disease and the importance of additional testing for T. cruzi when the post-test probability remains high even with a commercial, negative serologic test.
