Las CTO por reestenosis ¿tienen pronóstico diferente a las CTO de novo?

In-stent CTO: different prognosis from that of De Novo CTO?

Courtesy of Dr. Carlos Fava. Chronic Total Occlusions (CTO) are truly challenging and different technologies are being developed to treat them, but currently our most pressing questions about them are whether in-stent CTO present the same success rate as de novo CTO, and what their prognosis is.   The present trial analyzed 899 CTO: 111(12.3%)...

Aterectomía rotacional

Incidence of ‘Slow Flow’ After Rotational Atherectomy of Calcified Arteries

Courtesy of Dr. José Álvarez ‘Slow flow’ may complicate a rotational atherectomy procedure, especially when done on severely and extensively calcified lesions and small caliber vessels. Although its incidence is between 3% and 27%, its cause remains unclear, and it is thought that platelet antiaggregation induced by burr rotation speed may be behind it.  ...

Infarto agudo de miocardio y lesiones de múltiples niveles

Primary angioplasty and multivessel lesions: how should we proceed?

Courtesy of Dr Carlos Fava. The association of primary angioplasty with multivessel lesions is not infrequent and has been analyzed in various studies and meta-analyses. However, the proper course of action remains unclear. According to this study, fractional flow reserve (FFR) could better define the ischemic impact of lesions and help with the identification of...

angioplastía coronaria

Is Impella an option in high-risk angioplasty?

Courtesy of Dr. Carlos Fava. Provitional ventricular assist devices are increasingly used in high-risk angioplasties, particularly those involving unprotected left main coronary artery (LMCA) with defective ventricular functioning. However, so far its true role has not been well-studied.   This study analyzed 127 consecutive patients in the USpella registry from 2008 to 2015. These subjects underwent high-risk...

Contrast Induced FFR: Cost and Time Effective Alternative

Courtesy of Dr. Guillermo Migliaro.   Fractional flow reserve (FFR) is the radio of two flows expressed as the ratio of two pressures ─ distal pressure across stenosis (Pd) to aortic pressure (pa) ─ obtained only under maximal coronary hyperemia, which is a state of drug induced maximal vasodilation.   The gold standard to create...

angiografia error

Visual Assessment and Misinterpretation of Coronary Lesion Severity

  Courtesy of Dr. Pablo Baglioni. The visual interpretation of coronary angiographies is still used to decide for or against revascularization of ambiguous coronary lesions. Multiple factors other than stenosis degree, have been associated with the functional significance of lesions. The aim of this study was to analyze the ability of interventionists to visually assess...

Impacto negativo de la hipertensión pulmonar en el TAVI

Hemodynamic, Functional and Clinical Response to Pulmonary Artery Denervation in Patients with Pulmonary Hypertension

Original Title: Hemodynamic. Functional and Clinical Responses to Pulmonary Artery Denervation with Pulmonary Artery Hypertension of Different Causes. Phase II Results from the Pulmonary Artery Denervation 1 study. Reference: Circ Cardiovasc Interv. 2015;8   Courtesy of Dr. Guillermo Migliaro. Hospital Alemán, Buenos Aires, Argentina. The mechanisms responsible for pulmonary artery hypertension (PAH) are multifactorial. PAH reduces...

Vascular complications after valvular replacement using catheter: PARTNER trial findings

Reference: Généreux, et al, for the PARTNER Trial Investigators. JACC 2012; 60 (12):1043-62 Original title: Vascular complications after Transcatheter Aortic Valve Replacement: Insights From the PARTNER (Placement of AoRTic TraNscathetER Valve) Trial The purpose of the study was to investigate the incidence, predictors and vascular complications impact after catheter aortic valve implantation (TAVI) in the PARTNER...
