BACKGROUND: The optimal duration of dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation remains undetermined, especially for those at high risk of cardiac events postprocedure. OBJECTIVES: This study was aimed to investigate the impact of 6 versus 12 months of DAPT after DES implantation based on risk stratification with the residual SYNTAX score (rSS). METHODS: A total of 2737 patients in the I-LOVE-IT 2 trial were grouped according to rSS status (low rSS [rSS = 0, n = 1474] versus high rSS [rSS > 0, n = 1263]) and DAPT duration (6 months vs...

Familial hypercholesterolemia is an autosomal dominant disorder due to mutations in the low-density lipoprotein receptor gene, characterized by skin and tendon xanthomas, xanthelasmas, and increased risk of premature coronary artery disease. Here, we report a case of 9-year-old girl who presented with angina and dyspnoea on exertion with xanthomas and an elevated serum cholesterol and triglyceride. She had severe stenosis of the left main coronary artery (LMCA) requiring angioplasty and placement of Bioresorbable vascular scaffold (BVS)...

Primary percutaneous coronary intervention (PCI) is the treatment modality of choice in patients presenting with ST elevation myocardial infarction (STEMI). Clinical outcomes have dramatically improved with the wide adoption of primary PCI in patients with STEMI because of acute thrombotic native coronary artery occlusion. However, patients with prior coronary artery bypass graft (CABG) surgery who present with STEMI because of acute saphenous vein graft (SVG) occlusion continue to have worse outcomes because of poor acute and long-term results of SVG stenting...

BACKGROUND: Percutaneous paravalvular leak (PVL) closure is an alternative treatment option for severely symptomatic, high-surgical risk patients with PVL. Some patients require multiple percutaneous PVL closure procedures. However, the procedural characteristics and success rate of re-do PVL closure have not been well studied. AIMS: The aim of this study is to investigate the indications, procedural characteristics, technical success rate, and 30-day major adverse cardiovascular events (MACE) in patients who underwent re-do PVL closure...

Acute coronary syndrome (ACS) including spontaneous coronary artery dissection (SCAD) has been reported to trigger its own clinical twin takotsubo syndrome (TS). The pathogenetic association between SCAD and TS remains to be elucidated. The two diseases afflict predominantly women and both conditions may be triggered by an emotional stress factor and an unusual extreme physical exercise. Herein, we describe a case of 54-year-old woman presenting with ACS caused by an obtuso-marginal SCAD. Concurrently, the patient had typical clinical features and course of mid-apical pattern of TS...

OBJECTIVES: To assess patients' perspective about factors associated with stent choice. BACKGROUND: Drug eluting stents (DES) markedly reduce the risk of repeat percutaneous coronary intervention (PCI), but necessitate a longer duration of dual anti-platelet therapy (DAPT) as compared with bare metal stents (BMS). Thus, understanding patients' perspective about factors associated with stent choice is paramount. METHODS: Patients undergoing angiography rated, on a 10-point scale, the importance (1 = not important, 10 = most important) of avoiding repeat revascularization and avoiding the following potential DAPT drawbacks: bleeding/bruising, more pills/day, medication costs and delaying elective surgery...

OBJECTIVES: To describe the feasibility and safety of the Hopscotch Technique, a novel method to close paravalvular leaks. BACKGROUND: Successful closure of paravalvular leaks requires the complete seal of irregular defects, frequently interrupted by remaining sutures or tissue that converts a large defect into a complex series of contiguous smaller defects. Successful treatment with devices placed in a single space is impossible with constrained appearance and significant residual leak; therefore, new techniques to deploy smaller devices in the correct location are needed...

Severe tricuspid regurgitation (TR) remains a vastly undertreated disease, with sustained elevation of right atrial (RA) pressure directly resulting in chronic end-organ damage. Recently, bi-caval valve implantation has been shown to improve symptoms in patients with symptomatic TR who are at high risk for surgery. We present the first report of intermediate term hemodynamic effects of single inferior vena cava (IVC) valve implantation (CAVI) for treatment of severe TR. We performed CAVI on a 66-year-old female with severe TR, who suffered from repeat hospitalizations for treatment refractory NYHA class III-IV heart failure symptoms and had prohibitive operative risk...

A 55-year-old man underwent successful percutaneous coronary intervention for the middle left circumflex artery with a 3.5 × 28-mm bioresorbable vascular scaffold (BVS). At 18 months, follow-up coronary angiography showed ectatic change with aneurysm formation over the BVS. Optical coherence tomography revealed absence of strut continuity at the aneurysm site, in the middle of the BVS. A literature review identified nine patients with intrascaffold aneurysm, including the present patient, which developed 6-32 months after BVS implantation...

Physiologic assessment using fractional flow reserve (FFR) to guide percutaneous coronary interventions (PCI) has been demonstrated to improve clinical outcomes, compared to angiography-guided PCI. Recently, resting indices such as resting Pd/Pa, "instantaneous wave-free ratio", and contrast medium induced FFR have been evaluated for the assessment of the functional consequences of coronary lesions. Herein, we review and discuss the use of FFR and other indices for the functional assessment of coronary lesions...

Coronary artery perforation during percutaneous coronary intervention is a rare, but potentially lethal complication. Immediate balloon expansion at the perforation site can halt the bleeding. Implantation of a coronary polytetrafluoroethylene (PTFE)-covered stent enables the efficient endovascular repair of a coronary artery perforation. However, if the perforation occurs at a bifurcation, a PTFE-covered stent may jail the side branch. We report a difficult case of blowout coronary perforation (Ellis type III) at a left main coronary artery bifurcation, which was successfully sealed with a PTFE-covered stent without interference with the side branch coronary artery circulation...
