Acute severe mitral regurgitation (MR) is the commonest indication for emergency surgery following a balloon mitral valvuloplasty (BMV). It results in hemodynamic compromise with cardiogenic shock and or acute pulmonary edema. These patients deteriorate fast and often require respiratory and critical care support, followed by urgent mitral valve replacement (MVR). We analyzed the data of 1224 BMV procedures done over the 18-year period. We had 85 patients (6.9%) with acute severe MR and cardiogenic shock. The clinical profile, echocardiographic features and operative findings were studied...

This study aims to elucidate 1-year clinical outcomes using this technique for patients with stage 4 or 5 advanced chronic kidney disease (CKD). Research has proven that imaging-guided percutaneous coronary intervention (PCI) reduces contrast volume significantly; however, only short-term clinical benefits have been reported. Minimum-contrast (MINICON) studies are based on the registry design pattern to enroll PCI results in patients with advanced CKD stage 4 or 5 comorbid with coronary artery disease. We excluded cases of emergency PCI or maintenance dialysis from this study...

Percutaneous coronary intervention (PCI) for heavily calcified lesions is challenging because these lesions are resistant to balloon dilatation and stenting. Lacrosse non-slip element (NSE) may have the potential to dilate heavily calcified lesions. We aimed to investigate predictors of successful lesion modification using Lacrosse NSE angioplasty via optical coherence tomography (OCT)-guided PCI. We investigated 32 patients with severe target lesion calcification treated with OCT-guided PCI. Successful lesion modification was defined as the complete fracture of calcification after Lacrosse NSE angioplasty...

The objective is to evaluate our center's experience with the safety and efficacy of the percutaneous approach to endovascular abdominal aortic aneurysm repair (PEVAR) with use of the Perclose Proglide device, in the first period after introduction in our center in 2014. We retrospectively identified all patients that underwent PEVAR or endograft extension with percutaneous approach in our center in the urgent and elective setting. Included were all procedures performed between the introduction of the technique in January 2014 and February 2016 when PEVAR had become the predominant technique in our center...

Transcatheter aortic valve replacement (TAVR) has been recognized as a well-established alternative to surgical aortic valve replacement (SAVR) for symptomatic aortic stenosis with high surgical risk. With this updated systematic review and meta-analysis, we evaluated TAVR vs. SAVR in low- and intermediate-risk subjects. Studies comparing TAVR and SAVR in low-risk patients (defined as STS ≤ 8% or EuroSCORE ≤ 20%) were identified with electronic searches. The principal endpoint was all-cause mortality at short term (< 3 months), 1, and 2 years...

Given that parameters used in the calculation of the PRECISE-DAPT risk score are important contributors to contrast-induced nephropathy (CIN) development, we hypothesized that the PRECISE-DAPT risk score would show good accuracy for predicting CIN in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Therefore, in this study, we aimed to determine the predictive value of the admission PRECISE-DAPT score for the occurrence of CIN in patients with STEMI treated with primary PCI...

We aimed to evaluate the impact of tissue characterization for in-stent restenosis (ISR) with optical computed tomography (OCT) during excimer laser coronary angioplasty (ELCA) in the drug-eluting stent (DES) era. The effect of ELCA for ISR according to differences in tissue characteristics is unclear. Fifty-three ISR lesions (7 bare metal stents and 46 drug-eluting stents) were treated with an ELCA catheter. After ELCA, balloon dilatation with either the scoring or non-compliant balloons was conducted. The procedure was completed by applying a drug-coated balloon...

The burden of peripheral artery disease (PAD) and diabetes in Asia is projected to increase. Asia also has the highest incidence and prevalence of end-stage renal disease (ESRD) in the world. Therefore, most Asian patients with PAD might have diabetic PAD or ESRD-related PAD. Given these pandemic conditions, critical limb ischemia (CLI) with diabetes or ESRD, the most advanced and challenging subset of PAD, is an emerging public health issue in Asian countries. Given that diabetic and ESRD-related CLI have complex pathophysiology that involve arterial insufficiency, bacterial infection, neuropathy, and foot deformity, a coordinated approach that involves endovascular therapy and wound care is vital...

We aimed to compare the efficacy and safety of transcatheter aortic valve implantation (TAVI) using Edwards SAPIEN 3 (S3) valve and SAPIEN XT) in smaller anatomy. The new generation S3 TAVI device has been used worldwide; however, its efficacy and safety in smaller Asian anatomy remain unknown. Between February 2014 and March 2017, 166 consecutive patients (S3, 54; XT, 112) were treated with balloon-expandable TAVI in a single center and their outcomes were analyzed. Median patient age was 85 (range: 81-88) years and mean body surface area was 1...

The extension support guiding catheter has been used to perform complex percutaneous coronary intervention to increase back-up support for the guiding catheter or to ensure deep intubation for device delivery. However, because of its monorail design, advancement of the stent into the distal extension tubing segment is sometimes problematic. Although this problem is considered due to simple collision of the stent, operators have observed tangling between a monorail extension catheter and coronary guidewire in some patients...

Crossover stenting of femoral bifurcation raises the concern of jeopardizing the deep femoral artery (DFA) entry, thereby increasing future risk of limb-threatening ischemia and amputation. This retrospective multicenter study compared clinical outcomes of crossover stenting and non-crossover stenting for ostial superficial femoral artery (SFA) lesions. We reviewed 125 limbs in 103 patients with successful stent implantation for ostial SFA lesions and allocated them to two groups, based on whether the stent crossed over the DFA orifice (CO, n = 54) or not (NC, n = 71)...

We investigated the effect of low-density lipoprotein cholesterol (LDL-C) on the geometry of coronary bifurcation lesions. A total of 300 non-left main bifurcation lesions in 298 patients from J-REVERSE registry were classified according to statin treatment status at admission (NT, non-treated; ST, statin-treated) and were further subdivided based on LDL-C levels with a cutoff of 100 mg/dL (NT-high, n = 76 lesions; NT-low, n = 46; ST-high, n = 99 and ST-low, n = 79). In addition, a group with strict control of LDL-C (< 70 mg/dL) was defined (ST-SC; n = 19)...

We hypothesized that patients who had previous target-lesion revascularization (TLR) for DES restenosis in non-left main coronary artery (LMCA) lesions might have a higher risk for restenosis after subsequent DES implantation for a de novo unprotected LMCA lesion. Among 1809 patients enrolled in the Assessing Optimal Percutaneous Coronary Intervention for LMCA (AOI-LMCA) registry, which is a retrospective 6-centre registry of consecutive patients undergoing LMCA stenting in Japan, 251 patients with previous DES implantation for non-LMCA lesions were subdivided into the 2 groups with (N = 56) or without (N = 195) previous TLR in non-LMCA lesions...
