Transcatheter Mitral Valve Interventions for Mitral Regurgitation: A Review of Mitral Annuloplasty, Valve Replacement, and Chordal Repair Devices
Khatib, Diana; Neuburger, Peter J; Pan, Sabrina; Rong, Lisa Q
Significant mitral regurgitation (MR) is the most common valvular disease in the United States in patients older than 75. However, many patients with severe MR are at a high risk for surgical repair due to other significant comorbidities. Over the past decade, many transcatheter mitral valve devices have been studied that address the different mechanisms of MR, but only a few have received a ConformitÃ© EuropÃ©ene (CE) mark or United States Food and Drug Administration (FDA) approval. The Carillon, Cardioband, and Mitralign all received CE marking for percutaneous mitral annuloplasty, while the Tendyne and SAPIEN 3 received a CE mark and FDA approval, respectively, for transcatheter mitral valve replacement. Finally, the NeoChord DS 1000 received a CE mark for transcatheter chordal repair. Each of these devices is reviewed in detail, including device indications, performance in clinical trials, anesthetic management, intraprocedural imaging guidance, and postprocedural complications. Although percutaneous devices will appear and disappear from use, understanding the procedural considerations remains highly relevant, as these key principles will apply to the next generation of transcatheter valve interventions.

Complications of Transesophageal Echocardiography: A Review of Injuries, Risk Factors, and Management
Patel, Kinjal M; Desai, Ronak G; Trivedi, Keyur; Neuburger, Peter J; Krishnan, Sandeep; Potestio, Christopher P
Transesophageal echocardiography (TEE) use has become widespread in cardiac surgical operating rooms over the last 2 decades. Surgical and medical decision-making often are guided by the findings of the TEE examination, rendering TEE an invaluable tool both inside and outside the operating room. TEE has become ubiquitous in some parts because it is considered safe and relatively noninvasive. However, it is imperative for clinicians to understand that TEE can cause severe and possibly life-threatening complications, and the risks of TEE must be balanced against its benefits as a diagnostic tool. Upper gastrointestinal (UGI) injuries are the most commonly described complications of TEE; however, the relative infrequency of injuries and lack of uniform reporting make it difficult to definitively identify potential risk factors. Some large retrospective trials suggested that patient factors (age, body mass index, anatomic abnormalities), comorbid conditions (previous stroke), and procedural variables (procedure time, cardiopulmonary bypass time, etc.) are associated with TEE-related injuries. In this narrative review of complications from TEE, the authors focus on the incidence of UGI injuries, the spectrum of injuries associated with TEE, risk factors that may contribute to UGI injuries, as well as diagnosis and management options. Lastly, the discussion focuses on the prevention of injuries as TEE use continues to become more prevalent.

Functional Tricuspid Regurgitation in Patients With Chronic Mitral Regurgitation: An Evidence-Based Narrative Review
Patel, Kinjal M; Kumar, Nakul S; Neuburger, Peter J; Desai, Ronak G; Krishnan, Sandeep
Chronic mitral regurgitation leads to a series of downstream pathologic changes, including pulmonary hypertension, right ventricular dilation, tricuspid leaflet tethering, and tricuspid annular dilation, which can result in functional tricuspid regurgitation (FTR). The five-year survival rate for patients with severe FTR is reported to be as low as 34%. While FTR was often left uncorrected during left-heart valvular surgery, under the assumption that correction of the left-sided lesion would reverse the right-heart changes that cause FTR, recent data largely have supported concomitant tricuspid valve repair at the time of mitral surgery. In this review, the authors discuss the potentially irreversible nature of the changes leading to FTR, the likelihood of progression of FTR after mitral surgery, and the evidence for and against concomitant tricuspid valve repair at the time of mitral valve intervention. Lastly, this narrative review also examines advances in transcatheter therapies for the tricuspid valve and the evidence behind concomitant transcatheter tricuspid repair at the time of transcatheter mitral repair.
