Relación entre calidad del vaso distal y resultados en tratamiento percutáneo de las oclusiones totales crónicas

ERCTO Registry: Current Results for Percutaneous Treatment of Chronic Total Occlusions

Chronic total occlusions (CTO) occur in up to 20% of patients undergoing diagnostic angiographic studies. Over the past two decades, the optimization of recanalization techniques, the development of new specialized devices, and improvement in operator skill have contributed to an increased procedural success rate, reaching 90%. However, specific complications such as collateral perforation and access...

Disnea y oclusiones totales crónicas: un síntoma que podemos aliviar (o al menos intentarlo)

Contemporary Outcomes of CTO PCI in Europe: The ERCTO Registry

Roughly 20% or coronary angiographies show some form of chronic total occlusion (CTO), and this figure is twice as high for diabetic patients or those with cardiac failure and reduced ejection fraction (EF). CTO percutaneous intervention (PCI) has experienced a significant growth thanks to the development of new techniques and dedicated material. However, a considerable...

Use of Intravascular Lithotripsy vs. Rotational Atherectomy for Severely Calcified Coronary Lesions

Severely calcified coronary stenosis poses a significant challenge for coronary angioplasty procedures. Modifying plaque before stenting is crucial to a successful intervention, since it will prevent the sub expansion associated to worse clinical outcomes at followup.  The tools employed to assess complex lesions include specialized balloons such as cutting, scoring, or high pressure balloons, as...

La clave para tratar strokes: saber cuando detenerse

Predictors of Stroke at 30 Days and 6 Months After TAVR

While the rate of stroke has decreased since the early days of transcatheter aortic valve replacement (TAVR), it remains non-negligible, reaching up to 1%-3% at 30 days. As TAVR progressively expands to low-risk populations and younger patients, identifying risk factors for patient selection and management in stroke prevention becomes crucial. While researchers have identified predictors...

¿Es la litotricia coronaria tan efectiva como la aterectomía rotacional?

ROTACUT Study: Rotational Atherectomy with Cutting Balloon for Stent Expansion Optimization

Approximately 30% of patients undergoing percutaneous coronary intervention (PCI) present moderate to severe calcified lesions, which presents a significant challenge involving a high incidence of major adverse cardiovascular events (MACE). Rotational atherectomy (RA) is used to modify these calcified lesions and facilitate balloon angioplasty followed by stent implantation. The combination of RA with other plaque...

¿Es la litotricia coronaria tan efectiva como la aterectomía rotacional?

Is Coronary Lithotripsy as Effective as Rotational Atherectomy?

Severely calcified lesions currently pose a significant challenge, as they require adequate preparation through non-compliant balloons or cutting balloons to achieve effective stent expansion. Another option is the use of orbital or rotational atherectomy (RA), but this carries the risk of complications such as slow/no reflow, perforations, dissections, peri-procedural infarction, or guidewire rupture. Despite the...

OBSERVANT II: Post TAVR 30-Day and 6-Month Stroke Predictors

Despite stroke rate has declined since the early days of transcatheter aortic valve replacement (TAVR), it remains significant, reaching 1% to 3% 30 days after procedure. Since TAVR has seen a progressive expansion to the low risk and young populations, identifying risk factors in patient selection and management is crucial for us to prevent stroke. ...

ROTA.shock Outcomes: Intravascular Lithotripsy vs. Rotational Atherectomy

At present, severe calcified coronary stenosis poses a significant challenge for PCI. A successful intervention will require plaque modification prior stenting, seeing as sub-expansion has been associated with worse clinical outcomes at followup.  The tools normally used to treat these complex lesions include specialized balloons such as cutting, scoring, and high pressure balloons, as well...
