ABSTRACT

AIM: Transcatheter mitral valve-in-valve (TMViV) replacement for degenerated surgically implanted bioprosthetic valves has been described by both transseptal and transapical approaches. The balloon-expandable Myval transcatheter valve (Meril Life Sciences, Vapi, India) is commonly used for transcatheter valve-in-valve procedures in India. This study aimed to report in-hospital, 30-day, and 1-year outcomes of Myval patients who underwent TMViV in a single tertiary care centre in India. METHODS: Symptomatic patients with surgical bioprosthetic mitral valve failure with New York Heart Association (NYHA) class III-IV symptoms, despite optimal medical therapy and high or very high risk for redo surgery, were assigned to TMViV following heart team discussions. Data were retrospectively collected and outcomes assessed. RESULTS: Twenty patients were treated, with mean age 64.4 years, 60% were female, and mean Society of Thoracic Surgeons (STS) predicted risk of operative mortality score was 8.1. The failure mechanism was combined stenosis and regurgitation in 60% of patients. Technical success was achieved in 100% of patients. The mean postprocedure and 30-day gradients were 4.6±2.7 and 6.3±2.1, respectively. None of them had significant valvular or paravalvular leaks or left ventricular outflow tract obstruction. All-cause mortality at 1 year was 10%, and all survivors were in New York Heart Association (NYHA) class I or II. CONCLUSION: TMViV replacement with a Meril Myval can be safely performed with high technical success, and low 30-day and 1-year mortality.

ABSTRACT

OBJECTIVES: Information on normative reference values for cardiac structures is critical for the accurate application of echocardiography for guiding clinical decision-making. Many studies using transthoracic echocardiography (TTE) have shown that Indians have smaller diameters of various cardiac structures. There are no normative studies for transesophageal echocardiography (TEE). The authors observed dimensions of various cardiac structures in healthy Indian patients under general anesthesia using TEE and compared them with existing guidelines from non-Indian data. DESIGN: The Indian Normative TEE Measurements study was a multicenter, prospective observational study conducted in India. SETTING: Operating rooms for noncardiac surgeries in tertiary care-level hospitals. PARTICIPANTS: Adult patients undergoing noncardiac surgery who were free from any cardiac, respiratory, and renal diseases and had no contraindications for TEE. INTERVENTIONS: After inducing general anesthesia and achieving stable hemodynamic conditions, a comprehensive TEE examination was performed and various measurements were made. MEASUREMENTS AND MAIN RESULTS: For each of the 83 patients undergoing noncardiac surgery, 39 various measurements for left ventricle, right ventricle, both atria, and all valves were made. This included diameters and functional parameters. They were analyzed in a vendor-neutral software off-line. The absolute values of many of the measurements were higher in men, but when indexed to body surface area (BSA) they were similar in both sexes. The values were lower than most of the Western data but matched previous Indian studies using TTE. CONCLUSIONS: The authors present normative values of various echocardiographic parameters using TEE. Because of its variations, it is recommended to use India-specific data to make decisions in Indian patients. It may be prudent to use BSA-indexed values during decision-making.

ABSTRACT

In infective endocarditis, the perivalvular abscess is a known complication with an incidence of more than 22%-29%, but the primary presentation of a healed aortic abscess without any clinical features of infective endocarditis is very rare. These sorts of cases are scarcely documented throughout literature. We present a successful surgical closure of healed perivalvular abscess cavity with aortic valve replacement and mitral valve repair.

ABSTRACT

We describe a case of submitral aneurysm in a 40-year-old man, which was distinctive in its anatomy and pathophysiology. The patient had a congenital submitral aneurysm located in the anterolateral part of the mitral annulus, complicated by dissection of the left atrial wall, severe mitral regurgitation, and compression of the left circumflex artery. He was managed successfully with aid of a comprehensive preoperative evaluation with all available imaging guidance and methodical surgical techniques, resulting in exclusion of the aneurysm, mitral valve replacement, and a graft to the left circumflex artery.
