Ventricular septal myomectomy (VSM) is the primary modality for left ventricular outflow tract gradient reduction in patients with obstructive hypertrophic cardiomyopathy with refractory symptoms. Comprehensive postprocedural data for VSM from a large multicenter registry are sparse. The primary objective of this study was to evaluate postprocedural mortality, complications, length of stay (LOS), and cost of hospitalization after VSM and to further appraise the multivariate predictors of these outcomes. The Healthcare Cost and Utilization Project's Nationwide Inpatient Sample was queried from 1998 through 2010 using International Classification of Diseases, Ninth Revision, procedure codes 37.33 for VSM and 425.1 for hypertrophic cardiomyopathy. The severity of co-morbidities was defined using the Charlson co-morbidity index. Hierarchical mixed-effects models were generated to identify independent multivariate predictors of in-hospital mortality, procedural complications, LOS, and cost of hospitalization. The overall mortality was 5.9%. Almost 9% (8.7%) of patients had postprocedural complete heart block requiring pacemakers. Increasing Charlson co-morbidity index was associated with a higher rate of complications and mortality (odds ratio 2.41, 95% confidence interval 1.17 to 4.98, p = 0.02). The mean cost of hospitalization was $41,715 ± $1,611, while the average LOS was 8.89 ± 0.35 days. Occurrence of any postoperative complication was associated with increased cost of hospitalization (+$33,870, p <0.001) and LOS (+6.08 days, p <0.001). In conclusion, the postoperative mortality rate for VSM was 5.9%; cardiac complications were most common, specifically complete heart block. Age and increasing severity of co-morbidities were predictive of poorer outcomes, while a higher burden of postoperative complications was associated with a higher cost of hospitalization and LOS. •Higher postoperative mortality was found after VSM than reported in recent studies.•Age was predictive of higher postoperative mortality and complications.•Higher burden of co-morbidities predicted higher postoperative mortality and complications.•More postoperative complications were associated with longer LOS.

Pulmonary embolism (PE) is a life-threatening condition and a leading cause of morbidity and mortality. There have been many advances in the field of PE in the last few years, requiring a careful assessment of their impact on patient care. However, variations in recommendations by different clinical guidelines, as well as lack of robust clinical trials, make clinical decisions challenging. The Pulmonary Embolism Response Team Consortium is an international association created to advance the diagnosis, treatment, and outcomes of patients with PE. In this consensus practice document, we provide a comprehensive review of the diagnosis, treatment, and follow-up of acute PE, including both clinical data and consensus opinion to provide guidance for clinicians caring for these patients.

In the landscape of healthcare, the management of myocardial infarction (MI) stands as a pivotal challenge and a critical juncture where advancements are reshaping the trajectory of patient care. Myocardial infarction, commonly known as a heart attack, remains a foremost contributor to global morbidity and mortality. Conventional management strategies have historically focused on rapid restoration of blood flow through revascularization techniques. However, the last decade has witnessed a profound transformation, with a burgeoning emphasis on precision medicine and innovative interventions. This contextual backdrop sets the stage for a deep dive into the realm of novel diagnostic modalities, spanning high-sensitivity biomarkers, advanced imaging techniques, and data-driven algorithms. These innovations facilitate not only early detection but also the stratification of patients, paving the way for individualized treatment plans. By targeting the underlying mechanisms of myocardial damage, these interventions hold the promise of attenuating the impact of MI and promoting cardiac regeneration. It examines the integration of telemedicine, wearable devices, and remote monitoring platforms, bridging the gap between patients and caregivers while enabling timely interventions. Additionally, the psychosocial aspects of MI recovery are explored, highlighting the integration of psychological support and lifestyle interventions to enhance long-term well-being. By exploring novel diagnostics, innovative therapies, and holistic patient-centered strategies, it underscores the collaborative efforts of medical practitioners, researchers, and technological pioneers in reshaping the trajectory of MI care. As we stand at the intersection of medical advancement and compassionate patient management, embracing these novel approaches promises a future where the impact of myocardial infarction can be mitigated, and lives can be extended and enriched.

AngioVac is a vacuum-based device approved in 2014 for percutaneous removal of undesirable materials from the intravascular system. Although numerous reports exist with regard to the use of the AngioVac device in aspiration of iliocaval, pulmonary, upper extremity, and right-sided heart chamber thrombi, very few data are present demonstrating its use in treatment of right-sided endocarditis. In this case report, we describe the novel device used in debulking a large right-sided tricuspid valve vegetation reducing the occurrence of septic embolisation and enhancing the efficacy of antibiotics in clearance of bloodstream infection. Further research is needed in larger RSIE patient populations to confirm the benefits and the potential of improved outcomes associated with the AngioVac device as well as identify its potential complications.

The AngioVac is a vacuum-based device introduced in 2012 to percutaneously remove undesirable material from the intravascular system. In scattered reports, the AngioVac has been used for removal of device-led vegetations and right-sided thrombi. In this article, we describe three cases of right-sided endocarditis treated with AngioVac: a mobile mass extending from the vena cava into the right atrium, large native tricuspid vegetations, and bioprosthetic tricuspid vegetations. This device shows benefit in reducing vegetation load, decreasing septic lung embolization, and reducing reinfection in active intravenous drug users. These cases exhibit the AngioVac's arrival as a new and exciting tool in endocarditis treatment, providing an alternative to open surgery and accessorizing antimicrobial treatment.

Aortic dissection type A is a life-threatening condition that frequently necessitates surgical intervention. This review focuses on central aortic cannulation, arch branch vessel (ABV) cannulation, and proximal arch cannulation as key techniques during aortic surgery. It discusses innovative solutions for addressing these challenges. The review synthesizes findings from recent studies and emphasizes the significance of meticulous planning and execution of cannulation in aortic dissection repair. This review aims to contribute to the advancement of surgical practices and the enhancement of patient outcomes in the management of type A aortic dissection (AAD) by addressing these frequently overlooked details.

The increase in the number of carotid artery stenting (CAS) procedures over the last decade has necessitated critical appraisal of procedural outcomes and patterns of utilization including cost analysis. The main objectives of our study were to evaluate the postprocedural mortality and complications after CAS and the patterns of resource utilization in terms of length of stay (LOS) and cost of hospitalization. We queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample from 2006 to 2010 using the International Classification of Diseases, Ninth Revision, procedure code of 00.63 for CAS. Hierarchical mixed-effects models were generated to identify the independent multivariate predictors of in-hospital mortality, procedural complications, LOS, and cost of hospitalization. A total of 13,564 CAS procedures (weighted n = 67,344) were analyzed. The overall postprocedural mortality was low at 0.5%, whereas the complication rate was 8%, both of which remained relatively steady over the time frame of the study. Greater postoperative mortality and complications were noted in symptomatic patients, women, and those with greater burden of baseline co-morbidities. A greater operator volume was associated with a lower rate of postoperative mortality and complications, as well as shorter LOS and lesser hospitalization costs. In conclusion, the postprocedural mortality after CAS has remained low over the recent years. Operator volume is an important predictor of postprocedural outcomes and resource utilization.

Contemporary large-scale data, regarding in-hospital outcomes depending on the types of stent used for percutaneous coronary intervention (PCI) is lacking. We queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample from 2006 to 2011 using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure code 36.06 (bare-metal coronary artery stent, BMS) or 36.07 (drug-eluting coronary artery stent, DES) for PCI. All analyses were performed using the designated weighting specified to the Nationwide Inpatient Sample database to minimize bias. Primary outcome was in-hospital mortality. Wald's chi-square test was used for categorical variables. We built a hierarchical 2 level model adjusted for multiple confounding factors, with hospital identification incorporated as random effects in the model and propensity match analyses were used to adjust confounding variables. A total of 665,804 procedures were analyzed, which were representative of 3,277,884 procedures in the United States. Use of bare-metal stents (BMS) was associated with greater occurrence of in-hospital mortality compared with that of drug-eluting stents (DES; 1.4% vs 0.5%, p <0.001). The association stayed significant after adjustment of various possible confounding factors (odds ratio for DES versus BMS 0.59 [0.54 to 0.64, p <0.001]) and also in propensity matched cohorts (1.2% vs 0.7%, p <0.001). The results continued to be similar in the following high-risk subgroups: diabetes (0.57 [0.50 to 0.64, <0.001]), acute myocardial infarction and/or shock (0.53 [0.49 to 0.57, <0.001]), age >80 (0.66 [0.58 to 0.74, <0.001]), and multivessel PCI (0.55 [0.46 to 0.66, <0.001]). In conclusion, DES use was associated with lesser in-hospital mortality compared with BMS. This outcome benefit was seen across subgroups in various subgroups including elderly, diabetics, and acute myocardial infarction as well as multivessel interventions.

Catheter related thrombosis (CRT) is a commonly encountered entity fraught with substantial risk for mortality secondary to various complications including pulmonary embolism (PE), tricuspid regurgitation, endocarditis, right sided heart failure, and cardiogenic and septic shock. CRT carries a mortality rate of 18% in hemodialysis patients and more than 40% in nonhemodialysis patients. Management strategies include systemic anticoagulation, systemic thrombolysis, surgical evacuation, and percutaneous retrieval with no established guidelines. Ultrasound assisted catheter directed thrombolysis emerges as promising modality with a relatively lower risk of hemorrhage compared to systemic thrombolysis. We report a case of a 75-year-old man with dialysis catheter related thrombosis without PE for which ultrasound assisted catheter directed thrombolysis was used successfully as an alternative therapy.

We sought to study the feasibility of axillary artery as alternative access for mechanical circulatory support (MCS) in cardiogenic shock and high-risk percutaneous coronary intervention (HR-PCI) patients with severe occlusive peripheral artery disease (PAD). In patients with severe PAD, the iliofemoral artery may be so diseased preventing deployment of MCS, precluding the use of lifesaving therapy. In such circumstances, the axillary artery may be a viable access site. Records of all patients presenting with cardiogenic shock or HR-PCI requiring MCS through axillary artery access at our institution from January 2016 to September 2018 were examined. Demographics, clinical, procedural, and outcomes data were collected on all patients. A total of 48 patients presented with cardiogenic shock (60%) or HR-PCI (40%) requiring MCS via axillary artery due to prohibitive PAD (mean age 66 ± 11 years). Admission diagnoses were non-ST segment elevation myocardial infarction (38%), unstable angina (23%), ST segment elevation myocardial infarction (19%), and cardiac arrest (21%). Time from axillary access to activation of Impella was 11.9 ± 4 minutes. Four patients required concomitant Impella RP for right ventricular support due to biventricular cardiogenic shock. Twenty-two patients died before Impella was explanted due to multiorgan failure, stroke, and infection. None of the patients who died had vascular complications related to axillary access. Axillary artery appears to be a viable alternative access for large bore devices in patients with prohibitive PAD. As experience of the field with this approach grows, it may be the default access for deployment of large bore sheaths in the future.
