A 60-year-old male with recurrent episodes of supraventricular tachycardia on regular medications had another episode. Was taken up for electrophysiological study and radiofrequency ablation (EPS and RFA) under 3-D electro-anatomical mapping (EAM). The challenges in the case were need for isoprenaline infusion for sustenance of tachycardia and relatively wider area of ablation requirement for success.

Concentric calcific neo atherosclerosis is a rare cause of in-stent restenosis, which is more common in bare metal stents (BMS). It is a cause of undilatable lesions during the intervention and needs additional lesion preparation. 1 We report the use and effectiveness of ultra-high pressure balloons in this setting with intravascular imaging. A 68-year-old man with a history of percutaneous coronary intervention (PCI) to the left anterior descending artery (LAD) in 2008 with a bare-metal stent now presented with unstable angina. Coronary angiography showed severe restenosis of the LAD stent with slow flow (Figure 1A). The first optical coherence tomography (OCT) run showed intimal hyperplasia with severe concentric calcific neoatherosclerosis in the proximal stent with calcium extending more than 180 degrees in circumference (Figure 1B). Predilation with noncompliant

Background: Drug-coated balloons (DCB) are frequently used to treat femoropopliteal artery disease. However, patency loss occurs in ≥10% of patients within 12 months posttreatment with poor understanding of the underlying mechanisms. Objectives: The authors sought to investigate the determinants of DCB failure in femoropopliteal disease. Methods: Data from randomized clinical trials (IN.PACT SFA, MDT-2113 SFA Japan) and 2 prespecified imaging cohorts of the IN.PACT Global Clinical Study were included. Influential procedural characteristics were evaluated by an independent angiographic core laboratory. The primary endpoint was DCB failure (patency loss during follow-up). Additional endpoints were binary restenosis and clinically driven target lesion revascularization. Multivariable analyses evaluated the clinical, anatomical, and procedural predictors of DCB failure. Results: Included were 557 participants with single lesions and 12-month core laboratory-adjudicated duplex ultrasonography. Key clinical characteristics were as follows:

Corresponding author: Juan Salazar, Instituto de Investigaciones de Enfermedades Cardiovasculares de La Universidad del Zulia, Maracaibo, Venezuela. E-mail: juanjsv18@hotmail.com A 24-year-old female patient, without family or personal pathological history, came to the outpatient service because of frequent episodes of palpitations accompanied by generalized weakness and dizziness without loss of consciousness, a duration of several hours, and their selflimited nature. A 12-lead electrocardiogram was performed, which showed sinus rhythm, 88 beats per minute, a short PR interval, a widened QRS complex with initial slurring, and repolarization changes, findings that are consistent with that of Wolff–Parkinson–White (WPW) pattern, possibly right inferior paraseptal atrioventricular accessory pathway (Figure 1A). During the procedure, a right inferior paraseptal atrioventricular (previously called right posteroseptal) accessory pathway was found, with right atria stimulation radiofrequency energy applied with fixed cycles of 500 ms, acquiring atrioventricular (AV) separation and dissociation of ventriculoatrial retroconduction, and an electrocardiogram in sinus rhythm with 88 beats per minute, a PR interval of 160 ms, a QRS complex of 80 ms, a QRS axis of 60°, and symmetrical T-wave inversion (TWI) in DII, DIII, and aVF leads (Figure 1B). Radiofrequency ablation was performed without atrial pacing. The patient was discharged without instantaneous complications. During the follow-up evaluation, 10 days after the procedure, the patient was asymptomatic, with no new episodes of palpitations, and an electrocardiogram in sinus rhythm with 83 beats per minute, PR interval of 160 ms, QRS complex of 80 ms, QRS axis of 60°, and normal repolarization changes (Figure 2). The patient was managed conservatively due to a suspicion of cardiac memory phenomenon . The secondary changes in ST segment and T-wave are due to alterations in the ventricular activation sequence.

Percutaneous coronary intervention for chronic total occlusion is a complex and high-risk intervention (CHIP). Even though persistent ischemia-induced mitral regurgitation is rare, ischemic mitral regurgitation is a frequent complication of an acute coronary crisis. Transcatheter mitral repair has the potential to supplant surgical repair or replacement as the gold-standard treatment for persistent mitral regurgitation. Currently, these interventions are only performed on high-risk surgical candidates, but the indications may eventually be expanded to include low-to-intermediate risk patients as well, in a manner like transcatheter aortic valve replacement. In patients with ischemic cardiomyopathy who still had considerable viable myocardium, combining current guideline-directed pharmacological treatment with interventional complete revascularization decreased hospitalizations for heart failure. We performed a CHIP intervention on the left circumflex artery, which was chronically totally occluded, to address the severe ischemic mitral regurgitation that had been present for a long time.

Recently, we came across the development of new-onset atrial fibrillation (AF) while performing fractional flow reserve (FFR) for the two patients with borderline lesions of the left anterior descending (LAD) and right coronary arteries (RCA). The use of adenosine for the termination of supraventricular tachycardia is a common indication. The hemodynamic evaluation of a coronary lesion prior to revascularization has grown after the publication of the FAME and FAME 2 trials.1,2 In the catheterization laboratory, intracoronary or intravenous adenosine is used to document the significance of borderline lesions as a vasodilator. Transient bradyarrhythmia is known as an adverse effect. The development of AF following intracoronary or intravenous infusions of adenosine is a rare occurrence.3,4

Iatrogenic left main coronary artery (LMCA) dissection is a rare complication of percutaneous coronary intervention (PCI), it is mainly attributed to the catheter-based manipulation during engagement of Ostia or during the intervention. LMCA dissections are very dynamic ranging from a small, stable, and localized tear to extensive dissection obstructing coronary branches and cardiac arrest. Without prompt intervention, it often is a fatal complication. In this case series, we report three cases of LMCA dissection and their management with intravascular ultrasound-guided PCI.

Isolated subclavian artery is a rare anomaly where the subclavian artery, instead of originating from the aorta, is connected to the ipsilateral pulmonary artery via ductus arteriosus. Presentation varies from asymptomatic to vertebrobasilar insufficiency and claudication of the ipsilateral arm. About 100 odd cases were reported in the literature. Some of them underwent definitive surgical repair, ie, reimplantation and others underwent percutaneous closure of patent ductus arteriosus thereby reducing stealing of blood and improvement of circulation in the ipsilateral arm. We are reporting a case of isolated left subclavian artery with a rare association of bilateral PDA.
