Aims: In this study, we sought to evaluate the safety and efficacy of cryoballoon (CB) based empirical left atrial appendage (LAA) isolation as an adjunct to pulmonary vein isolation (PVI) compared to the PVI-only strategy in patients with persistent AF. Objectives: Clinical outcomes of catheter ablation were less beneficial for persistent atrial fibrillation (AF) than paroxysmal AF. Methods and results: A total of 100 consecutive patients with persistent AF underwent both PVI and additional LAA isolation using CB (Group II)...

Treatment of painful internal snapping hip via arthroscopic release of the iliopsoas tendon is becoming the preferred option over open techniques because of the benefits of minimal dissection and fewer complications. However, complications do occur with arthroscopic techniques as well. We present the case of a 33-year-old woman who presented with painful internal snapping of her right hip and underwent arthroscopic release of the iliopsoas tendon. Following the procedure she continued to complain of pain in her groin and was therefore investigated further with a magnetic resonance imaging (MRI) which revealed a swelling near the femoral circumflex vessels...

Coronary artery aneurysm following drug-eluting stent implantation is rare in the literature. The presentation combined a life-threatening condition with severe in-stent restenosis. How to treat this condition is a complex problem because a surgical approach for a proximal left circumflex lesion is difficult. A hybrid method that is a combination of coronary bypass surgery and coronary stenting for left main bifurcation in-stent restenosis and proximal coronary artery aneurysm is a feasible strategy.

Covered stents are indicated for coronary perforations, but they may seal off major side branches in that process. We report the successful sealing of an ostial left main perforation, induced by a guide catheter in the course of a retrograde approach to treat a chronic total occlusion (CTO) of the right coronary artery (RCA) in a 76year old woman with prior CABG. The implanted Papyrus covered stent, however, overlapped the left main bifurcation and occluded the non-grafted circumflex artery (CX) resulting in acute ischemia...

PURPOSE: Although abdominal-based flaps remain the first choice for autologous breast reconstruction, alternative donor sites are necessary when the abdomen is unavailable. Abdominal donor site suitability is determined, at times, according to deep inferior epigastric perforator (DIEP)-protocol computed tomographic angiography (CTA) results. CTA provides information about the pelvis/upper thigh that can be used to evaluate the suitability of other donor sites. This study aimed to examine the utility of DIEP-protocol CTA in the assessment of a lateral thigh perforator (LTP) flap...

Drug-eluting stents (DES) reduce risk of in-stent restenosis after percutaneous coronary intervention (PCI) but require dual antiplatelet therapy (DAPT) for a longer term than bare-metal stents (BMS). Few studies have examined clinical predictors of DES vs BMS, and variability in provider selection between DES and BMS in clinical practice has not been well described. These insights can inform our understanding of current practice and may identify opportunities to improve decision-making stent selection decinsion-making...

A 64-year-old woman was followed by the other hospital because of left ventricular false aneurysm after percutaneous coronary intervention for acute myocardial infarction of which culprit lesion was left circumflex artery. She admitted to the hospital suffering from nausea and dyspnea. Echocardiography showed huge pericardial effusion and cardiac tamponade due to ruptured left ventricular false aneurysm and transferred to our hospital under pericardial drainage. She presented with symptoms such as shock, so we performed emergent left ventricular reconstruction...

Mandibular reconstruction in osteoradionecrosis or salvage surgery can often be complicated by the lack of suitable recipient vessels in the ipsilateral neck and the associated requirement for significant extraoral skin reconstruction. The scapula tip with its long vascular pedicle and option of a chimeric soft tissue component offers a versatile reconstructive solution in such cases. This article reports four consecutive cases of mandibular reconstruction with poor ipsilateral vascular options and additional soft tissue requirements in which the scapula tip was justified and preferred...

Congenitally corrected transposition of the great arteries (CTGA) is a rare congenital heart disease. In patients with functional CTGA with circumflex artery occlusion and mitral regurgitation (MR), the right ventricle functions as the left ventricle. Coronary artery bypass grafting with mitral valve replacement is an effective treatment for CTGA with concomitant myocardial infarction (MI) and MR.

Vascular quadrilateral space syndrome (vQSS) is an underdiagnosed cause of extremity ischemia, pain and paresthesia in overhand throwing athletes. The mechanism of vQSS is thought to result from repeated abduction and external rotation of the arm leading to a distraction injury of the posterior circumflex humoral artery (PCHA) as this courses through the quadrilateral space. This trauma may cause dissection and dissecting aneurysm formation. Thrombus from this arterial injury then embolizes down the arm resulting in the symptomatic presentation...

Craniomaxillofacial reconstruction using virtual surgical planning, computer-aided manufacturing, and new microsurgical techniques optimizes patient-specific and defect-directed reconstruction. A 3D customized free deep circumflex iliac artery (DCIA) flap with intraoral anastomoses was performed on a 23-year-old man with a posttraumatic right zygomatico-maxillary defect with failure of alloplastic implant reconstruction. An osseous iliac crest flap was sculpted based on a customized 3D model of the mirror image of the patient's unaffected side to allow for perfect fit to the zygomatico-maxillary defect...

BACKGROUND: We have adopted an intraoral microsurgical anastomosis to the facial vessels to eliminate the need for any visible facial incisions. METHODS: Cadaveric dissection was used to demonstrate accessibility of the facial artery and vein through an intraoral approach. Additionally, 5 patients underwent free tissue transfer for reconstruction of major defects of the midface through an intraoral, transmucosal approach, obviating the need for visible skin incisions...

We report a case of an incidental finding of an anomalous left circumflex coronary artery arising from the right pulmonary artery that effectuated a ventricular fibrillation cardiac arrest in a woman aged 34 years. This rarity was detected during routine work-up to delineate the cause of this arrhythmia. Our patient had a background of double-outlet right ventricle and a ventricular septal defect, which was repaired with a Dacron patch and a left ventricle patch over to the aorta at age 14 months. Angiographic study at the time of her presentation showed anomalous origin of the left circumflex artery originating from the right pulmonary artery; this was discussed in multispecialty team meeting and surgical intervention was recommended; eventually, surgery was performed with reimplantation of the anomalous circumflex artery into the ascending aorta...

Management of obstructive coronary artery disease in patients with aortic stenosis and severe left ventricular dysfunction is challenging. Mechanical circulatory support at the time of percutaneous coronary interventions may be necessary in these extreme-risk patients. We present a case in which the TandemHeart was used to support a patient with severe aortic stenosis, severe protected left main and circumflex disease, and severe cardiomyopathy and review the literature on this subject.
