Transcatheter valve-in-valve implantation for degenerated stentless aortic bioroots.

Background: Open surgical repair of a failed valve-sparing aortic root replacement (VSARR) or stentless bioroot aortic root replacement (bio-ARR) entails significant operative risks. Whether valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is feasible in patients with a previous VSARR or stentless bio-ARR remains unclear, given lingering concerns about the ill-defined aortic annulus in these patients and the potential for coronary obstruction. We present our experience with patients who had a previous VSARR or stentless bio-ARR and underwent ViV-TAVR to repair a degenerated aortic valve with combined valvular disease, aortic insufficiency and aortic stenosis.

Hemodynamic outcomes after valve-in-valve transcatheter aortic valve replacement: a single-center experience.

Background: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) has emerged as a safe, effective alternative to redo aortic valve surgery in high-risk patients with degenerated surgical bioprosthetic valves. However, ViV-TAVR has been associated high postprocedural valvular gradients, compared with TAVR for native-valve aortic stenosis.

Methods: We performed a retrospective study of all patients who underwent ViV-TAVR for a degenerated aortic valve bioprosthesis between January 1, 2013 and March 31, 2019 at our center.

"Simple" Transcatheter Aortic Valve Replacement With Conscious Sedation: Safety and Effectiveness in Real-World Practice.

Transcatheter aortic valve replacement (TAVR) is a well-established alternative to open surgical replacement. Strictly selecting low-risk patients and using conscious sedation during TAVR has enabled hospital stays to be safely shortened. We evaluated the safety and effectiveness of a less rigorous patient-selection process involving multidisciplinary case discussions, percutaneous procedures with the use of conscious sedation, and postprocedural care outside an intensive care unit, with the goal of discharging patients from the hospital early.

Transcatheter aortic valve replacement after chest radiation: A propensity-matched analysis.

Background: Chest radiation therapy (CRT) for malignant thoracic neoplasms is associated with development of valvular heart disease years later. As previous radiation exposure can complicate surgical treatment, transcatheter aortic valve replacement (TAVR) has emerged as an alternative. However, outcomes data are lacking for TAVR patients with a history of CRT.

Endovascular Treatment of Superior Vena Cava Syndrome via Balloon-in-Balloon Catheter Technique with a Palmaz Stent.

Superior vena cava syndrome is a well-known disease entity that carries substantial rates of morbidity and mortality. Although most cases of superior vena cava syndrome are secondary to a malignant process, additional causes (such as mediastinal fibrosis, pacemaker lead implantation, or central venous catheter placement) have been reported. Multiple treatment options include percutaneous transluminal angioplasty, stent implantation, thrombolysis, mechanical thrombectomy, and venous grafting.

Transcatheter Aortic Valve-in-Valve Replacement Instead of a 4th Sternotomy in a 21-Year-Old Woman with Aortic Homograft Failure.

Transcatheter aortic valve replacement (TAVR) is a well-established method for replacing native aortic valves; however, it was conceived for elderly patients with aortic valve stenosis, and the lack of data on long-term durability has led practitioners to restrict the use of TAVR to patients who have short life expectancies. Here, we describe the case of a 21-year-old woman who had undergone 3 previous open aortic valve replacements and who presented with symptoms of recurrent valvular failure. Transthoracic echocardiograms and computed tomographic angiograms revealed a degenerating aortic root homograft with substantial calcification, moderate-to-severe aortic valve stenosis, and severe aortic valve regurgitation.

Endovascular Abdominal Aortic Aneurysm Repair by Means of the Chimney Technique in a Patient with Crossed Fused Renal Ectopia.

Crossed fused renal ectopia, a congenital anomaly in 1 of 7,000 individuals, presents a challenge during endovascular treatment of abdominal aortic aneurysm. Most treatment approaches in these patients have involved open surgical repair of the aneurysm or endovascular repair with coverage of the ectopic renal artery. We present what we think is the first case of endovascular abdominal aortic aneurysm repair with use of the chimney technique (parallel stent-grafting) to preserve an ectopic renal artery, in an 88-year-old man who was at high risk for open surgery.

Transvenous transcatheter valve-in-valve implantation after bioprosthetic tricuspid valve failure.

We describe the case of a 38-year-old man with a history of metastatic testicular cancer who had undergone multiple thoracic surgical procedures, including tricuspid valve replacement with a bioprosthetic valve as a result of tricuspid involvement of his malignancy. He presented at our outpatient cardiology clinic with worsening fatigue, shortness of breath, and peripheral edema, investigation of which revealed severe tricuspid bioprosthesis stenosis with central regurgitation. Because of the patient's medical history, he was considered to be a high-risk surgical candidate.

Long-term results of aortic banding for complex infrarenal neck anatomy and type I endoleak after endovascular abdominal aortic aneurysm repair.

For many patients with abdominal aortic aneurysm, unsuitable anatomy of the infrarenal aortic neck precludes endovascular aortic aneurysm repair or causes type I endoleak after the procedure. In an attempt to overcome these challenges, we retrospectively examined the usefulness of aortic banding as an adjunctive procedure to endovascular repair in 8 patients who had an abdominal aortic aneurysm with a complex infrarenal aortic neck. The procedures were performed with the patients under general anesthesia and involved making an 8-cm upper-midline laparotomy incision to expose the aneurysmal aorta.

Fistula from right internal mammary artery to superior vena cava after use of a laser sheath to extract a pacemaker lead.

A 55-year-old woman presented with dyspnea on exertion due to a right internal mammary artery-to-superior vena cava arteriovenous fistula that occurred after pacemaker lead extraction with a laser sheath. The fistula was successfully repaired by placing a covered stent in the right internal mammary artery. In this unusual location, endovascular stenting is a reasonable alternative to coil embolization or surgical repair of an arteriovenous fistula resulting from laser lead extraction.

Spontaneous celiac artery dissection case report and literature review.

Symptomatic spontaneous celiac artery dissection is a rare condition that is being detected more often with the use of advanced imaging techniques. There is no consensus as to whether surgical or endovascular treatment is more appropriate.We describe the case of a 41-year-old hypertensive woman who presented with the sudden onset of sharp, persistent, right-upper-quadrant abdominal and epigastric pain.

Low-permeability Gore Excluder device versus the original in abdominal aortic aneurysm size regression.

We sought to compare the efficacy of a low-permeability version of the Gore Excluder™ device with that of the original device. We used volumetric analysis and maximum transverse diameter measurements to examine abdominal aortic aneurysm size regression after endovascular aneurysm repair.From November 2002 through April 2007, 101 patients (82% men; mean age, 71.

Technical tips for endovascular treatment of abdominal aortic aneurysms with challenging infrarenal neck anatomy using the Excluder endoprosthesis.

Purpose: To report technical tips of endovascular aneurysm repair using Excluder endografts in patients with challenging infrarenal neck anatomy (short, angled, and/or tapered necks).

Technique: Several tips are presented to achieve effective and durable fixation and sealing of Excluder stent-grafts in abdominal aortic aneurysms (AAA) with challenging necks. The primary approach to patients with short infrarenal necks is a slow and controlled deployment combined with the bending-the-wire technique to realign the axis of the aneurysm and the axis of the neck.

Benefits of catheter thrombectomy during carotid stenting: a preliminary study.

Despite the use of distal embolic protection devices (DEPs) in carotid artery (CA) stenting, an appreciable risk of stroke exists, particularly in symptomatic patients. The mechanism of embolic events is possibly related to microembolization of atherothrombotic débris that remains or forms on the stent struts. This study evaluated the safety of using thrombus-extraction catheters in the setting of CA stenting.

Endovascular exclusion of popliteal artery aneurysms with stent-grafts: a prospective single-center experience.

Purpose: To determine the safety and efficacy of percutaneous treatment for popliteal artery aneurysms (PAA) using self-expanding stent-grafts.

Methods: From October 2000 through September 2007, 29 patients (27 men; mean age 68+/-6 years, range 54-88) underwent endovascular exclusion of 33 PAAs. All had symptoms of claudication, and all were atherosclerotic in origin.

Endovascular repair of paraanastomotic aneurysms after aortic reconstruction.

We designed this retrospective study to evaluate the effectiveness of percutaneous approaches for repair of paraanastomotic aneurysms that develop after surgical aortic reconstruction. The catheterization records of patients who had undergone percutaneous repair of para-anastomotic aneurysms from January 2001 through December 2005 were reviewed, and data regarding preoperative aneurysm size, risk factors, intraoperative techniques, morbidity, and death were recorded. Eight patients had undergone exclusion of a total of 10 paraanastomotic aneurysms.

Endovascular repair of a ruptured descending thoracic aortic aneurysm.

Endovascular aneurysm repair has considerable potential advantages over the surgical approach as a treatment for thoracic aortic rupture, in part because open surgical repair of ruptured thoracic aortic aneurysms is associated with high mortality and morbidity rates. We describe the successful endovascular deployment of stent-grafts to repair a contained rupture of a descending thoracic aortic aneurysm in an 86-year-old man whose comorbidities prohibited surgery. Two months after the procedure, magnetic resonance angiography showed a patent stent-graft, a patent left subclavian artery, and complete exclusion of the aneurysm.

Celiac artery aneurysm: a case report.

Aneurysm of the celiac artery is an uncommon clinical problem; fewer than 180 cases have been reported in the world medical literature. Most patients are symptomatic at the time of diagnosis. However, occasionally such aneurysms are detected incidentally during diagnostic imaging for other diseases.
