Project description:BackgroundMitral valve (MV) repair or replacement surgery is indicated for a variety of conditions. Although uncommon, damage to the left circumflex (LCx) coronary artery, which courses in close proximity to the MV annulus, is a devastating complication.Case summaryThis report describes the case of a 63-year-old woman following re-operative MV replacement. Shortly after being transferred to the surgical intensive care unit after MV replacement, her EKG was notable for persistent inferolateral ST-segment elevations and reciprocal ST-segment depressions. Emergency transthoracic echocardiogram revealed a reduced left ventricular ejection fraction of 35-40% and mid to distal lateral wall motion hypokinesis. She was emergently taken to the cardiac catheterization laboratory where coronary angiography demonstrated complete occlusion of her mid LCx artery. She underwent urgent percutaneous coronary intervention of the lesion and was started on dual antiplatelet treatment, anticoagulation for comorbid atrial fibrillation, as well as guideline directed medical therapy with improvement in her EKG changes and cardiac function.ConclusionPrompt diagnosis and recognition of LCx injury is crucial. Management involves immediate percutaneous recanalization or surgical coronary bypass grafting.

Case Report: Optical coherence tomography to guide PCI of iatrogenic injury of the circumflex artery after minimally invasive mitral valve repair.

Project description:We present a case of a 42-year-old man who suffered an iatrogenic injury to his left circumflex (Cx) coronary artery after mitral valve (MV) repair surgery. After the patient suffered from myocardial infarction without ST-segment elevation following minimally invasive MV surgery, we performed repeated coronary angiography and optical coherence tomography (OCT), which revealed severe coronary stenosis of the dominant Cx caused by intramural hematoma. In addition, we proceeded with percutaneous coronary intervention and stent implantation.

Aorto - Left atrial fistula after mitral valve replacement.

Project description:Acquired aorto-left atrial fistula is uncommon. A rare case of aorto-left atrial fistula following mitral valve replacement is reported with echocardiographic, computed tomograpic and angiographic images.

Computed Tomography Planning for Transcatheter Mitral Valve Replacement.

Project description:Transcatheter mitral valve replacement (TMVR) is a rapidly evolving treatment for mitral regurgitation. As with transcatheter aortic valve replacement, multidetector computed tomography analysis plays a central role in defining the candidacy, device selection and safety for TMVR procedures. This contemporary review will describe in detail the multidetector computed tomography data collection, analysis, and planning for TMVR procedures in patients with native mitral regurgitation as well as in those with failed surgical prosthetic mitral valve replacement or surgical mitral valve repair.

Follow-up optical coherence tomography to evaluate circumflex ostium after fenestration of left main Papyrus covered stent: a case report

Project description:Abstract Background Left main (LM) perforations necessitating a covered stent risk sacrificing the side branch. The lost side branch can be promptly recovered by fenestration of the covered stent, using a stiff wire. However, it is unclear whether subsequent balloon angioplasty of the recovered side branch ostium is sufficient to preserve side branch patency. We report the longer-term patency of the circumflex (LCx) ostium after LM covered stenting. Case summary A 78-year-old lady, with stable angina, presented for elective angiography. Percutaneous coronary intervention of the left anterior descending (LAD) artery to LM was complicated by a distal LM perforation. A covered stent across the LM sealed the perforation but resulted in acute occlusion of the LCx. The LCx was rescued by fenestration of the covered stent with a stiff wire, followed by balloon angioplasty to the LCx ostium. At follow-up, the angina had resolved. However, follow-up angiography demonstrated a new severe stenosis at the LCx ostium, with remnants of the polyurethane membrane seen protruding into the LCx ostium on optical coherence tomography. Therefore, the LCx ostium was stented, using the reverse Culotte technique. Conclusion This case demonstrates that stenting the LCx ostium should be considered after covered stent implantation from LM to LAD, because balloon angioplasty of the LCx ostium may not provide a durable result in this scenario.

Phasic disappearance of left circumflex coronary artery from an early complication of mitral valve surgery.

Project description:LV pseudoaneurysm can be a late complication of mitral valve replacement. In our case, it was an early postoperative complication. This pseudoaneurysm was causing compression of LCX artery during systole, leading to presentation of NSTEMI two weeks after the surgery.

A case of left atrial dissection after mitral valve replacement.

Project description:Left atrial dissection (LatD) is a rare complication of cardiac surgery due to creation of a false chamber through a tear in the mitral valve annulus that extends into the left atrium wall. It is primarily associated with mitral valve surgery although other etiologies have also been defined. Perioperative transesophageal echocardiography (TEE) is a key to the diagnosis. This is a case report of management of LatD after mitral valve replacement.
