Balloon aortic valvuloplasty for urgent treatment of severe aortic stenosis during coronavirus disease 2019 pandemic: a case report

Balloon Aortic Valvuloplasty in the Modern Era: A Review of Outcomes, Indications, and Technical Advances

Balloon aortic valvuloplasty (BAV) improves the hemodynamics and symptoms of patients with severe aortic stenosis in the short term with low rates of complications, but has not been shown to be an effective destination therapy. Our pooled analysis of >14,300 patients from studies published between January 1, 1991, and April 31, 2022, reported intraprocedural mortality and in-hospital mortality rates as 1.94% (95% CI, 1.39%-2.59%) and 6.02% (95% CI, 4.83%-7.32%), respectively. Hence, BAV is primarily indicated as a bridge to aortic valve replacement/decision with secondary uses as bridge to noncardiac surgery and palliative therapy. Recent advancements in alternative access sites, balloon catheters, and lithotripsy for BAV have opened opportunities for expanded use and further improvements in complication rates. As the utilization of BAV has continually increased since the advent of transcatheter aortic valve replacement, reexamining the role and outcomes of BAV in the era of transcatheter aortic valve replacement has become increasingly important. This review focuses on the outcomes, indications, advances, and technical considerations for BAV.

ESC guidance for the diagnosis and management of cardiovascular disease during the COVID-19 pandemic: part 2-care pathways, treatment, and follow-up

AIMS

Since its emergence in early 2020, the novel severe acute respiratory syndrome coronavirus 2 causing coronavirus disease 2019 (COVID-19) has reached pandemic levels, and there have been repeated outbreaks across the globe. The aim of this two part series is to provide practical knowledge and guidance to aid clinicians in the diagnosis and management of cardiovascular (CV) disease in association with COVID-19.

METHODS AND RESULTS

A narrative literature review of the available evidence has been performed, and the resulting information has been organized into two parts. The first, which was reported previously, focused on the epidemiology, pathophysiology, and diagnosis of CV conditions that may be manifest in patients with COVID-19. This second part addresses the topics of: care pathways and triage systems and management and treatment pathways, both of the most commonly encountered CV conditions and of COVID-19; and information that may be considered useful to help patients with CV disease (CVD) to avoid exposure to COVID-19.

CONCLUSION

This comprehensive review is not a formal guideline but rather a document that provides a summary of current knowledge and guidance to practicing clinicians managing patients with CVD and COVID-19. The recommendations are mainly the result of observations and personal experience from healthcare providers. Therefore, the information provided here may be subject to change with increasing knowledge, evidence from prospective studies, and changes in the pandemic. Likewise, the guidance provided in the document should not interfere with recommendations provided by local and national healthcare authorities.

Balloon aortic valvuloplasty: current status and future prospects

INTRODUCTION

Balloon aortic valvuloplasty (BAV) improves hemodynamic and clinical status of patients with severe aortic stenosis (AS) for a limited period of 6-12 months. However, there is a high number of procedures performed worldwide and an upward trend over the last decades.

AREAS COVERED

Epidemiology of AS and the advent of transcatheter aortic valve implantation (TAVI) contribute to the extensive referral of patients. The expansion of recommendations for TAVI has occasionally led to financial reimbursement-related problems that do not exist for BAV. BAV is indicated as a bridge to valve replacement, to decision in complex cases, and to extracardiac surgery. BAV may play a role in preparing for TAVI and optimizing procedural results. The minimalist approach and reduced complication rate make it applicable in fragile patients.

EXPERT OPINION

In the near future, BAV will continue to be a useful asset in managing patients with AS given the multiple indications, broad applicability, safety profile, low cost, and repeatability. Specific studies are necessary to explore technical solutions, stronger indications, the finest technique, and to standardize the procedural result. Pending the development of potential competitive devices, the role that BAV plays will remain closely intertwined with the one played by TAVI.

Safety and Feasibility of Transcatheter Aortic Valve Replacement in COVID-19 Patients: A Case Series

In 2020, the coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in interventional treatment for structural heart disease worldwide. In this context, the management of patients with symptomatic severe aortic stenosis (AS) or bioprosthetic valve dysfunction (BVD) represents a clinical challenge, as a delay in aortic valve replacement procedures may increase short-term morbidity and mortality. We report four cases of TAVR performed in patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. All of them were discharged in good clinical conditions and no adverse events were reported at 30 days follow-up. Our experience suggests that in selected patients with mild SARS-CoV-2 infection and symptomatic native AS or BVD, TAVR has a favorable short-term outcome.

Balloon aortic valvuloplasty for urgent treatment of severe aortic stenosis during coronavirus disease 2019 pandemic: a case report

An 86‐year‐old man affected by severe aortic stenosis (AS) was referred to our institution owing to decompensated heart failure. Three months before, the patient was scheduled for transcatheter aortic valve implantation (TAVI), which was postponed owing to the coronavirus disease 2019 (COVID‐19) outbreak. Owing to COVID‐19 suspicion, he underwent nasopharyngeal swab and was temporarily isolated. However, the rapid deterioration of clinical and haemodynamic conditions prompted us to perform balloon aortic valvuloplasty (BAV) as bridge to TAVI. The patient's haemodynamics improved; and the next day, the reverse transcriptase–polymerase chain reaction for COVID‐19 was negative. At Day 5, he underwent TAVI procedure. Subsequent clinical course was uneventful. During COVID‐19 pandemic, the deferral of TAVI procedure should be assessed on a case‐by‐case basis to avoid delay in patients at high risk for adverse events. BAV may be an option when TAVI is temporarily contraindicated such as in AS patients suspected for COVID‐19.
