Safety and feasibility of same-day discharge after elective percutaneous balloon mitral valvotomy: a prospective, single-center registry in India.

BACKGROUND

Percutaneous mitral balloon valvotomy (PBMV) is an alternative to surgery for patients with severe mitral valve (MV) stenosis. However, the safety and feasibility of same-day discharge (SDD) in patients undergoing elective PBMV for severe MV stenosis is yet to be investigated. This study aimed to assess safety and feasibility of SDD in patients undergoing elective PBMV because of severe MV stenosis in a tertiary-care hospital in India.

METHODS

From January 2018 to November 2018, patients with a diagnosis of severe MV stenosis were treated with PBMV at our institution. Among these patients, those suitable for SDD were prospectively included in this registry. Vascular access was achieved in forearm arteries and femoral veins. Clinical, echocardiographic and hemodynamic features were collected before and after PBMV. The primary outcome was 30-day mortality. The secondary outcome was incidence of in-hospital complications. Other outcomes of interest were arterial spasm and forearm haematoma.

RESULTS

A total of 98 patients scheduled for SDD after elective PBMV were included in the registry. Mean MV area increased from 0.8 ± 0.1 to 1.6 ± 0.2 cm2 (p < .001). Severe MV regurgitation after PBMV occurred in 3 patients, and 1 patient developed pericardial tamponade. Severe arterial spasm occurred in 2 patients. None of the included patients developed a clinically relevant haematoma of forearm. A total of 94 (96%) were discharged on the same day. No patient died up to 30-day follow-up.

CONCLUSION

PBMV from the venous access site can reduce the hospital stay of patients to less than a day with less local site complications.
