"Use of Snare Catheter Technique in Transcatheter Aortic Valve Replacement With Self-Expandable Valve: Expert Review".

The use of the snare catheter (SC) technique has been described in the field of interventional cardiology, in particular in the retrieval of a lost device, for example, a dislodged coronary stent, broken coronary wire, and so forth. In the transcatheter aortic valve replacement (TAVR) procedure, some cases have been observed where the anatomy is challenging or there are scenarios where some complications occur during the procedure, which make it necessary to use some tools to achieve the success of the procedure. The SC has shown are very useful either to achieve the ascent of the valve to the annular plane in complex anatomies or as a rescue measure in the event of complications that may arise after valve implantation.

Transcatheter aortic valve replacement before to breast cancer management: case report and literature review.

Background: The coexistence of aortic stenosis (AS) and neoplastic pathology are common due to shared risk factors with atherosclerotic disease, such as diabetes, inflammatory conditions, and smoking. Severe AS in patients with cancer requires careful assessment in order to select the appropriate therapeutic choices and their timing (i.e.

High risk of coronary artery obstruction during TAVR, how to avoid it?

Background: Coronary artery obstruction after percutaneous aortic replacement is a complication with high short-term mortality secondary to the lack of timely treatment. There are various predictors of coronary obstruction prior to valve placement such as the distance from the ostia, the degree of calcification, the distance from the sinuses; In such a situation some measures must be taken to prevent and treat coronary obstruction.

Case Presentation: An 84-year-old male, with severe aortic stenosis and high surgical risk, who was treated with TAVR.

Transcatheter aortic valve replacement planning with cardiac computed tomography in quadricuspid aortic valve stenosis: a case series.

Background: The presence of severe aortic stenosis in quadricuspid aortic valve (QAV) is an extremely rare combination, and it is unknown whether transcatheter aortic valve replacement (TAVR) is a safe option due to the low incidence.

Case Summary: We present two patients diagnosed with severe aortic stenosis with QAV morphology type 1 (Nakamura classification). All patients presented to our hospital for evaluation because of worsening functional class, dyspnoea, or syncope.

Valve-in-valve as a rescue treatment in retrograde migration of the transcatheter aortic valve to the left ventricle: a case report.

Background: The treatment of choice for patients with severe symptomatic pure native aortic valve regurgitation (PNAVR) is surgical aortic valve replacement (SAVR). However, not all patients are candidates for surgery because of comorbidities or are deemed high risk for surgery. In such cases, transcatheter aortic valve replacement (TAVR) has proved to be better than medical treatment.

[Complete revascularization with PCI in STEMI patients with multivessel disease, when is the appropriate time?].

Objective: The purpose was to compare the outcomes of patients with ST-elevation myocardial infarction and multivessel coronary artery disease undergoing one-time multivessel revascularization (OTMVR) versus in-hospital staged complete revascularization with percutaneous coronary intervention.

Methods: This was a single-center, retrospective, observational, and cohort study, including data from January 2013 to April 2019. A total of 634 patients were included in the study.

Successful Closure of Paravalvular Leak Using Computed Tomography Image Fusion and Planning With 3-Dimensional Printing.

The presence of moderate to severe paravalvular leak increases mortality. We present a case of giant paravalvular leak closure using the 3-dimensional printing model to assess the success of the device to be used for its closure, computed tomography was performed for planning and guiding the procedure by image fusion. ().

Description of the Step-by-Step Technique With Snare Catheter for TAVR in Horizontal Aorta.

The presence of a horizontal aorta in patients treated with transcatheter aortic valve replacement increases the difficulty of the procedure. We present 5 cases with aortic stenosis with a horizontal aorta who underwent transcatheter aortic valve replacement using a self-expanding prostheses, with the objective of describing the techniques used and obtaining success with a snare catheter. ().

Tricuspid valve-in-valve procedure: a step-by-step guideline.

Objective: The aim of this study was to present a valve-in-valve (ViV) case and a step-by-step guideline on how to perform this procedure.

Methods: A 51-year-old female with a history of rheumatic heart disease and tricuspid valve replacement presented functional class deterioration, a transesophageal echocardiogram (TEE) revealed prosthetic dysfunction due to thrombosis; therefore, a valvular replacement with a 27 mm bioprosthesis (Carpentier-Edwards Perimount) was performed without complication. 3 years after the procedure, the patients presented functional class deterioration (NYHA-III) with tricuspid dysfunction by TEE and the heart team decided to perform a transcatheter tricuspid ViV replacement.

Development of the Mexican Heart Team: The Long and Winding Road.

Heart failure (HF) is the leading cause of death worldwide. Efforts to decrease HF mortality rates include a multidisciplinary approach management. Although evidence suggests that this has been an optimal strategy for treating HF, the model remains not widely implanted.
